Book Description
Excerpt from The Desert Corn Flea-Beetle In destroying its food plant, this beetle works from both ends, as it were, the adults attacking the plant above the ground and the larvae below the ground. The adults eat out the chlorophyll of the leaves, and when sufficiently numerous they cause the leaves to wilt. If feeding is long continued, new growing plants will be killed. AS the eggs are deposited below the surface of the ground, the larvae immediately begin feeding. Upon the roots, and soon the plant has quite a shallow root system that will not support it in a thrifty manner. The roots, after having been injured by the larvae, attempt to overcome this injury by sending out new laterals, as illustrated in figure 6, page 11, and then sometimes Slight windstorms will cause plants to blow over and lodge badly, thus further reducing the yield.

Book Description
Row by row - maximize your harvest and feed your soil by developing a customized plan for your garden Everyone loves to prepare a meal with ingredients fresh from their own garden. But for most of us, no matter how plentiful our harvest, homegrown produce comprises only a fraction of what we eat. And while many gardening guides will tell you everything you ever wanted to know about individual crops, few tackle the more involved task of helping you maximize the percentage of your diet you grow yourself. Grow a Sustainable Diet will help you develop a comprehensive, customized garden plan to produce the maximum number of calories and nutrients from any available space. Avoid arriving in August buried under a mountain of kale or zucchini (and not much else) by making thoughtful choices at the planning stage, focusing on dietary staples and key nutrients. Learn how to calculate: Which food and cover crops are best for your specific requirements How many seeds and plants of each variety you should sow What and when to plant, harvest and replant for maximum yield. Focusing on permaculture principles, biointensive gardening methods, getting food to the table with minimum fossil fuel input, and growing crops that sustain both you and your soil, this complete guide is a must-read for anyone working toward food self-sufficiency for themselves or their family.
