| Dear Organic Gardeners, |
|
It's that time! It's the time when gardening reaches a frenzy. As the last frost dates pass in many parts of the country, we're all busy transplanting starts, working beds, planting seeds, making compost, incorporating cover crops, harvesting our first green salads, and maybe even digging a few new beds for everything that doesn't fit. (Who needs a lawn anyway?) It's also one of the few times when our soil is laid bare, a good time to get intimate with it as we imagine bountiful harvests and fragrant bouquets, and to ask the question: Does our soil have the nutrients, organic matter and biological activity that our plants need to thrive? This month, our Agricultural Planner Steve Peters sheds a little light on the subject of soil with the first installment of his series on basic soil fertility, while Research Farm Associate Lee Gearheart reveals some of his foliar feeding secrets. In conjunction with our focus on fertility, we are pleased to introduce the complete line of "Earth Juice" liquid organic fertilizers and foliar sprays to complement your soil building program. Micaela Colley takes a break from the Farm Report this month to share her passion for cut flowers, and in her stead I've put together a photo essay on recent activities at the farm. Last month's piece on GMO's created a wave of response, some of which you'll find in the Letters to the Editor. And as always we've got photo tips, a Garden Story and other goodies. Happy planting, Contents | Seeds of Change Homepage |

| Soil Fertility Basics: Organic Matter by Steve Peters |
|
The key to growing healthy, nutritious plants is maintaining fertile soil. Much more than dirt, garden soil is a richly complex ecosystem that is as dynamic and diverse as a tropical rainforest. Most soil activity, however, is invisible to the human eye so we tend to think of soil as merely a medium for holding up plants. Nothing could be further from the truth. A single gram of soil can host billions of living organisms!
Finally, and perhaps most significantly, organic matter is the food source for soil based organisms, including bacteria, fungi, actinomycetes, yeasts, soil-dwelling insects and earthworms. Without these living organisms plants would cease to exist. They perform a variety of critical processes including: 1) Converting organic nitrogen, which is unusable to plants, into inorganic nitrogen compounds (ammonia and nitrates) which are available to plants; 2) fixing atmospheric nitrogen and making it available to plants; 3) producing organic acids that make mineral nutrients soluble and available to plants; 4) living symbiotically on plant roots and aiding the plant in the uptake of many important nutrients and growth substances; 5) preying on pathogenic organisms that would otherwise be detrimental; 6) contributing to soil aggregation by producing gum-like polysaccharides; and 7) producing carbon dioxide (CO2) which is released into the atmosphere and is essential for photosynthesis. As a home gardener, the best way to increase the organic matter content of your soil is to add mature, high quality compost. Composting is that seemingly magical process that transforms raw organic residues into a stable, sweet-smelling earthy substance that contains a balanced blend of all the essential plant nutrients. Compost can be applied to the soil at almost any rate without fear of toxicity or loss of nutrients, although more frequent, smaller applications are preferred. Compost provides a slow and steady release of nutrients throughout the growing season, and can cure a variety of problems including high or low pH or a nutrient imbalance. Mature compost is particularly important in sandy soils which lack the ability to retain much water or nutrients. Another important source of organic matter is >cover crops, which are grown specifically for soil improvement and are incorporated into the soil prior to growing vegetables and other garden plants. Cover crops can be grown any time of the year. Spring annuals (Oats and Triticale) are planted as soon as the soil can be worked in early spring. Summer annuals (Buckwheat, Cowpea, Sorghum) are grown only during frost-free months, while winter annuals (Austrian Winter Pea, Hairy Vetch, Winter Rye) are planted in late summer/early fall, overwinter, and resume growing the following spring. For longer term soil-building, biennials (Yellow Blossom Sweetclover) and perennials (Red Clover) can be grown. Cover crops are not as effective as compost for building humus, but they stimulate a greater amount of biological activity. In heavy clay soils, fresh cover crop residues may be preferred over compost because they help open up the soil and provide drainage. Raw animal manures are not generally recommended for direct application to the garden because much of the nutrients are lost by leaching. They can also introduce unwanted weed seeds and pathogens, and can cause over-stimulated leafy growth because of excess available nitrogen. We recommend composting raw manures before putting them in the garden.
There are soil tests available through many cooperative extension services and private soil testing laboratories, which can give you an idea of the organic matter content of your soil. However, this is often not cost effective for the home gardener. A simple way to measure the biological activity in your soil is to measure CO2 respiration, which is associated with the breakdown of organic matter by soil microorganisms. Higher levels of biological activity in the soil reflect healthier soils, which provide essential plant nutrients like nitrogen and phosphorous. The Woods End Institute, a leading soil and compost quality laboratory, has developed a simple method for the home gardener to test for CO2 respiration in soil and compost. Please look for the Solvita Garden Care Test in our product offerings below. Steve Peters, Agricultural Planner with his prized Paxton Hoe.

| Garden Help: Foliar Feeding |
|
Foliar feeding is just that: feeding your plants through the foliage. When nutrients are applied directly to the leaves, they are absorbed quickly into the plant through the stomata, tiny mouth-like organs on the leaves that facilitate nutrient intake and gas exchange. Mostly they are located underneath the leaves, especially in the sun-loving plants, so when you spray, be sure to get underneath the plant's leaves and allow some to drip onto the soil to nourish microorganisms and plant roots. Never spray during the heat of the day, as the food and magnification principles of the water droplets can burn the leaves. Early mornings and evenings are best. I prefer evenings because this gives the nutrients to the plant during its nighttime respiration period when the stomata are most active. For large applications, a backpack sprayer is often used, but a hand held pump sprayer works well for most jobs. As for the number of applications throughout the season, I like to spray before the full moons, as the full moon energy pulls up and out through the plant. New moon applications are especially good for root crops, as it pulls energy downward. Be aware that foliar feeding isn't meant to supercede a good organic, soil-building program, but it does add that extra nutrient boost at key plant-life events. Critical times include: in the nursery (in cell trays, flats, or containers), before and after food harvest to stimulate and inspire continued healthy production, and around early and late season frost times to lengthen the growing season and increase plant hardiness to environmental stresses. Spraying for frost protection works because the uptake of nutrients increases the soluble solids levels in plant tissues lowering the plant freezing point. There are a lot of foliar products available and just as many "recipes" to mix for their application. For large-scale farm applications, my favorite foliar spray so far is a blend of Maxi Crop, Algamin, Humex, and Therm-X 70. For garden-scale applications, or if you're not into blending your own mixes, Seeds of Change is now offering the "Earth Juice" liquid organic fertilizers and foliar sprays. Judging by the ingredient lists these should be very effective and can be used in various combinations depending on your needs. We'll keep you posted as we get results from our farm trials. Whatever you use, experiment, and come up with your own combinations. It's fun, and your plants will love you for it. They'll show their appreciation with such visible results: healthier plants, more, bigger, better tasting food, and taller, brighter flowers. Research backs it up, so give it a try. Have fun, and happy spraying!

Micaela's Cut Flower Seed Collection |
| Organic Cut Flowers by Micaela Colley |
|
When I do buy cut flowers I always try to purchase organically grown ones. I have been asked, "Why buy organic flowers? You're not going to eat them!" Actually, I have seen several children and pets put them in their mouths, but beyond that, I think of the effects of toxic pesticides on the people who work in the fields and greenhouses, as well as on the environment. The EPA's allowable levels of pesticide application are often significantly higher for flower production than for food crops meant for consumption. In part this is due to the consumer's demand for "perfection" which is especially stringent in ornamental crops. The commercial industry has also become strict in grading cut flower quality. Meeting these standards has led to increased pesticide use and lack of variety in the industry. Certain stem lengths, flower sizes, and lack of blemishes are required to make the grade as a #1 flower on the wholesale market. Therefore, flowers are often bred for intensive production or specifications of size or length rather than beauty and fragrance. Yet, flowers are a symbol of love and beauty. I feel there is beauty in diversity, irregularities, and imperfection. Doesn't it make sense that food for our soul should be as healthy as the food for our bodies? For many years the cut flower industry produced a select number of species for sale: roses, carnations, gladiolas, and a few others. In recent years, however, there has been a revolution in cut flower production. Because of innovative growers and the extensive research done by Alan Armitage (author of "Specialty Cut Flowers") at the University of Georgia, we now find flowers like Delphinium, Veronica, Larkspur, and Asters in many flower shops. Beyond these new selections there are endless possibilities for the home gardener. Growing your own flowers means that they travel straight from the garden to the vase and don't necessarily need to hold up for weeks, unlike a flower harvested, distributed, displayed in a florist shop, and eventually sold a week or two later. I like to experiment with cutting all kinds of flowers from my garden to see what will last.
This year each of our selections will be trialed at Four Sisters Farm, an organic cut flower farm in Aromas, California. (www.localharcest.org/farms/M1657) Four Sisters has been producing cut flowers for both wholesale and retail markets for the past 20 years. Their professional experience will give us information about the performance of our varieties in an organic production system. If you're interested in learning more about growing an abundance of organic cut flowers, please scroll down to our review of The Flower Farmer, an Organic Growers Guide to Raising and Selling Cut Flowers by Lynn Byczynski. Tips for growing cut flowers:
When selecting varieties for your cut flower garden, try to imagine how they will come together in a bouquet. Certain colors and shapes naturally compliment each other, but everyone has their own taste and sense of style. I like bold colors that set off one another. I call them Crayola colors: deep blue, bright yellow, vibrant red, and rich purple. Another approach is the calm beauty of an all white bouquet, or a subtle contrasting purple against predominately white. My best friend's wedding bouquet (which we composed together) was an unusual, eclectic mix of rich peach, and deep maroon set against chartreuse-colored foliage. Whatever your taste, let the artist in you compose your own creations. Seeds of Change Favorite Cut Flower Varieties
