| Dear Organic Gardeners, |
|
We've just returned from visiting many of the organic farmers who grow our seed. Thanks to their skill and dedication, it looks like we'll have plenty of great seed for next year despite the drought that has affected much of the country this summer. In our Farm Report, Micaela Colley discusses the importance of these visits to our mission of providing the best open-pollinated seeds possible. One highlight of our trip was seeing the beautiful crops of seed garlic drying in preparation for shipment to our warehouse. If you haven't ordered your organic fall planting garlic yet, don't wait much longer, as many varieties will sell out. In our own gardens, the harvest has begun in earnest as we dig new potatoes and savor the ever-expanding diversity of fresh food and flowers. If you're blessed with an over abundance of fresh produce this year, we've included a link to Plant a Row for the Hungry to help you find a good home for the excess. Another link from this newsletter is to the Organic Consumers Association. Please join their campaign to stop the use of genetically modified, Bt crops. Have you ever thought about testing your soil? Steve Peters, in his continuing series on soil, gives us some insight into the benefits and complexities of soil analysis. Also this month, we are excited to work with the great folks at Jerzy Boyz Organic Orchards to offer you and your friends some of the finest pears and apples available anywhere. Send a gift box to someone you care about and treat yourself to one too! New varieties will be available as the season progresses. With fall approaching, don't forget to check out our excellent new cold frames or make one of your own, to keep those veggies coming long into the season. In many climates, now is also the time to sow salad greens, spinach, and kale for fall harvesting or wintering over to get the earliest harvest in the spring. It's an exciting and bountiful time in the garden. Enjoy! |
| Farm Report: Visits With Our Growers by Micaela Colley |
|
We just returned from this year's visits, and once again are invigorated and inspired by these passionate and intelligent farmers. We believe that this direct connection to where and how our seed is grown sets us apart from most other seed companies. Unlike companies that buy from a middleman, we can trace our seed lines back to the fields where they were grown. Growing our seed on healthy, organic, family farms not only produces vigorous, long-lasting organic seed, but also plays an important role in supporting small-scale, organic agriculture across the country. Our seed growers are our eyes in the field. Each year, as they grow our seed crops they take care to ensure that our varieties are growing vigorously and true to type. All the seeds we offer are open-pollinated (OP) varieties, which means they freely cross-pollinate in the field. A particular variety's traits are maintained by continually selecting the plants with the desired characteristics. Unlike hybrid seed, OP seed may be saved from year to year and it will reproduce true to type as long as it has not been crossed with another variety of the same species. We offer OP varieties because we believe that seed saving and exchange is important to conserving genetic diversity and preserving our food crops for future generations. Offering OP varieties also avoids dependence on "professionals" to provide us with their selection of seed each year and allows us to adapt varieties to our own conditions. As Carol Deppe, author of Breed Your Own Vegetable Varieties, says, "every time you save seed you are doing plant breeding." She means that by saving seed we select, and nature selects, which plants our seed comes from, and therefore which genes remain in the gene pool. We can intentionally select plants with the most desirable characteristics, whether that is a particular color of zinnia, earliness of a tomato, or vigor of a broccoli.
Many root crops such as onions and carrots are biennial. The root is grown the first year, then dug up and replanted for seed production in the second year. With these crops much of the selection work is done when replanting the roots. A grower we just visited was selecting Torpedo Red Bottle Onions for the characteristic torpedo shaped bulb. He replanted only the onions with the proper shape and gave the rest to his daughter to fix for dinner. In addition to selection work and variety maintenance, some of our growers enjoy developing new varieties by cross breeding different varieties within a species. Frank Morton has been producing lettuces and other greens for mesclun salad mixes for years. His fascination has been with all the novel lettuce types he can produce by crossing different varieties. He crosses lettuces on his farm by interplanting different varieties and introducing pollen from one plant to another. Because lettuces don't readily cross unless planted right next to each other, he can perform several projects in a small area by separating each block of interplanted lettuce from the next by only a few feet. He has found the possibilities limitless, and surprises often emerge, such as interesting textures and colors, unique leaf shapes, or increased resistance to bolting or tolerance to cold.
Farmers are the original plant breeders. Those who continue this legacy through working to produce new varieties, inspire us immensely. After talking with our growers in the field, it is clear that their work is born out of passion. It takes care and dedication to walk a field every morning to observe hundreds or even thousands of plants and remove those with undesirable traits, before they have a chance to flower and degrade the variety. And, it takes patience and time to develop a new variety--cross pollinating, selecting and re-selecting until it is truly a unique and stable variety. Growing seed is unlike growing other crops. It requires heightened awareness and care. At Seeds of Change, our high quality organic seed is made possible through our relationship with an inspiring group of talented organic farmers. We extend many thanks and praise to our growers, (2) Selecting Torpedo Bottle onions at Eel River Farm. (3) Examining one of Frank Morton's many plant breeding projects.

The Botany of Desire A Plants Eye View of the World by Michael Pollan, Random House, 271 pages, hardcover, $20.90 |
|
Whether tending a few containers of flowers and herbs, a half acre of vegetables, or a thousand acres of corn, any caretaker of plants will at some point find themselves pondering their relationship to those plants. Those of us who save seeds may ponder this relationship even more deeply, as we decide not only which varieties to grow and how to do it, but also from which plants of those varieties to save our seed. Ultimately, all of these decisions are based on our desires. We ask ourselves, "What is it that we desire from these plants, and which plants come the closest to fulfilling those desires?" With "The Botany of Desire," Michael Pollan turns the tables and ponders this relationship from the plant's perspective. He convincingly reveals our role in nature as much more than selecting what species or traits to grow or preserve. Instead, Pollan portrays us as somewhat unwitting players, much like the honeybee, working in service of the plants as the plants, adapt to fulfill our innate longings. To make his case, Pollan examines our role in propagating four species that have transformed our culture in various ways, by playing to some of our deepest desires. He begins with the apple, the archetypal fruit, which, by appealing to our desire for sweetness (and hard cider) played an important role in our westward expansion across the continent. Through his image-rich recounting of Johnny Appleseed's story, Pollan demonstrates how a lowly fruit can seduce an entire culture. He continues on with the Tulip, focusing on the "tulipomania" that overtook Holland in the 1630's, at first fueled by the desire for novel beauty, then exacerbated by wanton greed. Pollan then delves into the ever-sensitive subject of marijuana, and how this plant, in satisfying our desire for intoxication (a term he struggles eloquently to define as it pertains to this specific plant) has transformed itself and proliferated throughout the world against all odds. Finally, and perhaps most alarming in scope, is his essay on the genetically engineered (GE) "new leaf" potato. Pollan poignantly discusses how this and other GE crops are leading to an entirely new brand of mono-crop agriculture, by seductively placating our desire for control over nature. Besides being a sensual and engaging read, Michael Pollan's "The Botany of Desire" offers us deep insight into the natural world and our role in it. And, not incidentally, woven through these pages is a compelling case for the preservation of biodiversity by gardeners throughout the world. S.V. |

The Complete Italian Vegetarian Cookbook 350 Essential Recipes for Inspired Everyday Eating by Jack Bishop, Houghton Mifflin, hardcover, $33.25
It's time for a new cookbook at our house. My husband's parents are here for the week so we have willing taste testers. My father-in-law, a self-described "meat and potatoes man" will be a true test for The Complete Italian Vegetarian Cookbook by Jack Bishop. Subtitled "350 Essential Recipes for Inspired Everyday Eating," the book is enhanced Ann Stratton's inspiring photographs of several dishes including "Summer Spaghetti with Raw Arugula and Tomatoes." As truly ripe heirloom tomatoes are now in season, I chose this recipe for our main course. For starters we chose "Crostini with Black Olive Spread and Capers." The spread, containing Gaeta olives, garlic, basil leaves, thyme, and lemon juice, turned out perfect Ð the little peppery bursts of the capers were a great addition Ð a flavorful and satisfying start.Along with the spaghetti, we created "Steamed Green Beans with Tarragon" and "Mixed Greens with Tomatoes, Yellow Pepper, and Fennel." The pasta sauce featured the light sweet flavor of fresh tomato and the wonderful spice of wilted arugula, complemented by ample garlic, olive oil, salt, and fresh ground pepper. The green beans, lightly steamed, drizzled with olive oil, and salted and peppered were greatly enhanced by the almost anise-like flavor of the tarragon. The tarragon transitioned nicely into the salad, with its thinly sliced fennel, yellow pepper, and tomatoes tossed with mesclun. Olive oil whisked with balsamic and red wine vinegars provided a simple dressing. I've never made macaroons before, but Bishop's "Pine Nut Macaroons" were testament to the clarity and simplicity of his writing. Sprinkled with a little powdered sugar after they came out of the oven, they were beautiful - maybe even elegant. Dinner was a great success and my father in law soon forgot about "what wasn't there." This cookbook expands what I think of as Italian, emphasizing what's fresh and in season, in lieu of heavy cheeses and long cooked sauces. I could use it every day and not tire of the variety and the flavor combinations that Mr. Bishop offers. C.P. |

| Stop Bt Crops Now! |
|
The following is excerpted from the BioDemocracy News #35, Please contact the EPA today and tell the agency to end the registrations for all Bt crops! Despite public opposition from consumers and mounting criticism from scientists, the Bush Administration's Environmental Protection Agency is about to make the decision within the next two weeks to "re-register" or to continue allowing untested and unlabeled genetically engineered Bt crops to be grown on millions of acres across the USA. Genetically engineered Bt corn, cotton, and potatoes have been spliced with bacterial DNA (Bacillus thuringiensis) to produce proteins that are toxic to some insect pests and butterflies. But as mounting evidence indicates Bt crops pose a serious threat to the environment, public health, and organic agriculture and should be taken off the market. The Organic Consumers Association and two national coalitions of which we are a member, Genetically Engineered Food Alert (www.gefoodalert.org) and the National Campaign for Sustainable Agriculture, urge you to send comments to EPA before August 31, 2001. To date, all commercialized genetically engineered insecticidal plants produce a type of Bt toxin, one of a family of related molecules produced by a soil bacterium, Bacillus thuringiensis (Bt). To develop what are known as Bt crops, a company clones the insecticidal gene from the bacterium and inserts it into a crop plant. The plant then produces the toxin in most, if not all, parts of the plant through all, or most, of a growing season.
We have set up a web page with sample letters and ready to send emails to make it as easy as possible for you to comment directly. The 30 day deadline for comments to the EPA ends August 31, so please send in your comments today. |

| Soil Fertility Basics #3: Interpreting Soil Tests by Steve Peters |
|
Passionate gardeners strive to understand the quality of their soil, for balanced, fertile soil is essential for producing healthy, nutritious plants. Physical characteristics of the soil such as texture, color, and smell are all significant indicators of soil quality that can be directly observed. Plant growth and the health of animals eating these plants are the most important indirect indicators of soil quality. Another very useful tool is the soil test, however, we need to understand what a soil test actually means and what its limitations are. A soil test gives us clues about our soil. It is not an exact science but can indicate trends and general nutrient ratios. It tells us whether a specific nutrient is abundant or is lacking and helps us take corrective action. As soil stewards we are trying to balance our essential soil nutrients. The soil test helps us achieve this goal. Soil tests are generally performed by professional soils laboratories. Perhaps the greatest value of these labs is their interpretation of the test results. As an alternative to the professional soil-testing lab, we offer the Lamotteä soil test (pH, nitrogen, phosphorus, potassium) which, while perhaps not as precise as a professional test, is more convenient and allows you to test frequently. Frequent testing combined with good record keeping means you can detect trends early and act accordingly. Complementing the Lamotte kit, we also offer the Solvita Garden Care test kit. This kit measures CO 2 respiration, which indicates a soil's biological activity. Results will indicate whether additional soil amendments, such as compost, are required. Because biological activity fluctuates over the season, it's a good idea to perform this test regularly. Taking Soil Samples. For your soil sample to yield meaningful test results, it should represent your entire field or garden site. From each of 10 - 20 locations throughout the garden, avoiding unusual spots such as wet areas or shaly knobs, take trowel full of soil from the top 6 Ð 8 inches. Place these in a clean plastic bucket. Mix the sample thoroughly with a plastic or wooden tool. Avoid touching the soil with your hands or an iron tool. Take your sample for testing from this. For a laboratory test you'll need about one pound. Soil tests are most useful if we can observe test results from the same field over several years. Sampling during the same time of year and using the same lab or testing methods will assure the most consistent results. Below are actual test results from two different soil samples, followed by a discussion of what this means for the gardener. Soil # 1 is from our research farm in northern New Mexico, within the Rio Grande floodplain. Soil #2 is from our northeast trial garden, which is in a forest clearing in southern Maine that was pasture over 80 years ago but had since grown back to pine forest (before being logged).
Organic matter (OM) is a measure of all plant and animal residues, ranging from raw, undecomposed materials to stable humus. It is a source of nitrogen, the major cations (Ca,Mg,K), trace minerals, and growth hormones. OM also stimulates biological activity and enhances soil structure and water retention. It is, however, perhaps the most difficult factor to interpret on a basic soil test, as optimum OM content can vary widely depending on soil type and conditions. Furthermore, the amount of nitrogen being released by OM depends heavily on the quality of the organic matter (stable vs. unstable compounds) and the soil conditions (texture, temperature, water content). Nevertheless, testing for OM can be useful to observe general trends if it is measured every year or two. OM levels can also indicate a soil's ability to retain nutrients. (See below in the discussion on cation exchange capacity. (CEC)) Soil #2 has a great amount of raw residues, which are useful for stimulating soil microbial activity, but do not contribute to nutrient retention. In contrast, humus and other more stable decomposed organic matter are very important nutrient sources. Note the higher CEC in soil #1, even though overall OM is considerably lower. Soil pH is a measure of the hydrogen ion (an electrically charged atom) concentration in the soil solution surrounding soil particles. Pure water (H2O) has a pH of 7.0 which is neutral because it contains equal amounts of H+ (Hydrogen) ions and OH- (Hydroxyl) ions. A pH below 7.0 is acid and has a greater number of H+ ions, while a pH above 7.0 is alkaline and has a greater proportion of OH- ions. Soil pH per se has little direct effect on plant growth, provided that a plant can extract a sufficient quantity of nutrients. The most important concept regarding pH is that extreme acid or alkaline conditions affect the availability of virtually all the essential nutrients. For example, at pH 5.0 (strongly acidic) the amount of calcium, magnesium, potassium, nitrogen, and sulfur available to plants is only half as much as at pH 6.0 (moderately acidic). The availability of phosphorus begins to decline at pH 6.5. Below 6.0, most phosphorous is unavailable to plants. As pH levels drop below 5.0, iron and aluminum are released from the soil in quantities that are toxic to plants. Excessive alkalinity also leads to nutrient imbalances. Many of the trace elements, including iron, manganese, boron, copper, and zinc become gradually less available at pH levels exceeding 7.5. Soils with pH above 7.5 also show dramatic decreases in phosphorus availability. Soil pH also affects the activity of beneficial soil microorganisms. Although bacteria and actinomycetes prefer alkaline conditions and fungi favor acidic conditions, the optimum overall activity of beneficial microbes occurs at mid-range pH levels. Therefore, a pH that is not extremely acidic or alkaline is best for maximizing soil life and plant-available nutrients. Soil #1 has a rather alkaline pH, and the soil test report indicated low levels of several of the trace elements (not shown here). One of the recommendations was to add gypsum (calcium sulfate) because the sulfur is able to acidify the soil slightly. The pH of Soil #2 probably doesn't need to be adjusted, however, if the pH was much lower, the most effective way of raising it would be through further applications of high calcium limestone (calcium carbonate) or dolomite (calcium-magnesium carbonate). Cation exchange capacity (CEC) is a measure of the soil's ability to retain the cation nutrients, including calcium (Ca+), magnesium (Mg+), potassium (K+), and nitrogen in the ammonium form (NH4+). These positively charged elements are attracted to the negatively charged surfaces of clay and humus particles. Once these cations are bound to these sites, they are protected from leaching away in water, yet they are still available for uptake by plant roots. As plants absorb the cations, their roots release positively charged hydrogen ions (H+), which then attach to the negatively charged sites previously occupied by the other cations. As a plant continues to take up the cation nutrients, there are more H+ ions on soil clay and humus particles and in the soil water solution surrounding the particles (i.e. more acidity). Therefore, more cation nutrients need to be added to assure an adequate future supply. At CEC levels above 20 or 25 (milliequivalents per 100 grams of soil), the soil can hold many more nutrients than a plant would normally need in a year. If the majority of exchange sites in this soil were occupied by the nutrient cations (and not by H+), then very little or no additional amendments may be required for the next 1 to 3 years. However, once this soil is depleted of nutrient cations, it would require a large input of nutrients to restore its original fertility. On the other hand, if a soil has a low CEC, say below 10, then the nutrient reserves would be quickly depleted, and annual additions of the cation nutrients may be required (although at much lower quantities than in a high CEC soil). Soil #2 has a low CEC and may need to be monitored more closely than soil #1, which has a moderate CEC level. CEC levels are largely dependent on the amount of clay (fine texture) and humus in the soil. Silty (medium texture) and sandy (coarse texture) soils contribute almost no exchange sites, and hence must be fertilized more often. Soil #2 is interesting in that it has a relatively low CEC but a large amount of organic matter (humus). The humus contributes a large number of exchange sites, yet the texture is silty (few exchange sites), so that the combined exchange site contribution of the humus and mineral portions of the soil is still relatively modest. Since the humus is contributing the lion's share of exchange sites, an increase in the pH will increase the CEC. In most soils, however, the CEC remains fairly constant, yet knowing what it is will help us determine the amount and frequency of fertilizer applications. The cation nutrients (Ca, Mg, K) are expressed in parts per million (ppm). If you multiply ppm by 2, you will get the approximate number of pounds/acre of the nutrient (in the top 6 inches of soil). Soil labs usually report the level of each of these cations from very high to very low, relative to the CEC of each particular soil. This explains why, although the calcium level of soil #1( higher CEC) is greater than soil #2 (lower CEC), the Nutrient Level Rating of soil #1 is lower. Considering this, the total amounts of the cation nutrients are not as important as the proportion of exchange sites that each of these cations occupies. This is expressed as the "% Base Saturation." Calcium dominates the exchange sites, and for best crop performance, should occupy 65 to 85 percent of the sites . Magnesium is best between 10 and 20 percent, while potassium should be about 3 to 5 percent. The remaining sites are occupied by hydrogen, sodium (high alkaline soils), ammonium, and trace elements. Even these ranges are not necessarily the best in all cases, but they can be used as guides for balancing your nutrients. Soil #1 is rated very high in potassium, which could lead to nitrogen deficiency. If your plants are not exhibiting N-deficient symptoms (yellowing of leaves, slow growth), then you probably have nothing to worry about. The calcium level of soil #1 is rated medium and the lab recommendation was to add gypsum (Calcium sulfate), which can be helpful in several ways. First, it raises the calcium level. Second, the calcium in the gypsum replaces some of the potassium on the exchange sites, allowing excess to leach away. Third, the sulfur in the gypsum decreases the pH, which increases the availability of several trace minerals. Soil #2 has high or very high levels of the major cations and their ratio appears to be ideal, therefore no major adjustments are needed. Phosphorus, like the cations, is also expressed in parts per million. Two tests are performed on this element. The P1 (weak Bray extraction) measures the amount of phosphorus immediately available to the plant. P2 (strong Bray extraction) measures the readily available P plus the active reserves, which usually are available later in the season. The P2 levels should be 2 or 3 times the P1 levels. Soil #1 had no P1 reported because this test is unreliable in soils above pH 7.5. P2 levels were very high in soil #1, so presumably no additional P is required. If phosphorus deficiency symptoms show up (purpling of leaves, poor root growth, poor flower/fruit set), the best strategy would be to lower the pH and increase biological activity through the addition of compost and green manure crops. Soil #2 had high P1 and P2 levels, and their ratio indicates no problems for supplying the crop throughout the season. If phosphorus levels are low, a colloidal, soft rock phosphate is best because it can supply adequate P over a relatively long period. Soil tests are not an absolute measurement of soil fertility, but they can serve as a valuable guide for indicating problem areas and what directions we may go to solve these problems. The subject of soil quality, health, and fertility is enormously complex, and the soil test is but one tool to help us unlock a small piece of the vast mysteries that lie below the surface. We, as stewards of the land, will do well to be intimately involved with our soil on a regular basis by feeling, observing, and reflecting. The rewards will be great for us as well as our gardens.
