The Farm as Ecosystem: Tapping Nature's Reservoir ─ Biology, Geology, Diversity
Format: PDF / Kindle (mobi) / ePub
Nature is complex, elegant, and infinite in its wisdom. Farmers who are truly successful learn nature's many facets and her intricate dance; they crack the code of how to honor and feed this boundless natural system while coaxing the production needed for the survival of a modern farm. Natural product formulator and farm consultant Jerry Brunetti wraps together a lifetime of learning and his uncanny observations in this fascinating volume on the interconnected dynamics in place on a farm -- the farm's geology, biology, and diversity of life forms. Learn to look at -- and manage -- your farm very differently through gaining a deeper understanding of the complementary roles of all facets of your farm. With his unique perspective the author takes readers on a journey through a farming ecosystem describing it with principles, stories, facts and science . . . and dotted throughout with real-world advice. This is a book which will be enjoyable to browse while rich enough to want to have a highlighter in hand.
Topics covered include:
• The physical, chemical and biological aspects of soil
• Understanding compost and compost tea
• Working with foliar nutrition
• The roles of trace elements in farming
• Water and your farm
• Cover cropping systems . . . and more.
my test of choice as the “AgriDynamics 3” test. This test includes the following: total exchange capacity (soil’s nutrient-holding capacity and exchange sites) pH organic matter (total, including active) estimated nitrogen release (ENR) or the estimated amount of organic nitrogen within the organic matter sulfur (anions) in ppm phosphate P205 in lbs/acre; (or phosphorus (P) in ppm) calcium in lbs/acre magnesium in lbs/acre potassium (potash or K20) in lbs/acre sodium in lbs/acre base saturation
(% of) calcium magnesium potassium 45 sodium other bases (e.g. Total of cation trace minerals in ppm; of Boron iron manganese copper zinc aluminum selenium chromium cobalt molybdenum silica Note: Mellich III Extraction will yield higher amounts of trace elements than DPTA. For example the range for manganese using DPTA would be 2.0–5.0 ppm. For Mellich III it would be 10–35 ppm. The last five are requested because selenium is not only vital to plant health, it’s critically important for
percent potash), organically acceptable Ammonium sulfate (21 percent nitrogen; 24 percent sulfur, a good balance of nitrogen with sulfur, not organically approved Magnesium sulfate (9.9 percent magnesium; 15–17 percent sulfur), organically acceptable Ammonium thiosulfate (12 percent nitrogen, 26 percent sulfur), not organically approved 14 Si 28.0855 Silica Target: >25 ppm Silica is the mineral with the largest concentrations in the soil, yet because of that it is considered a nonessential
entry point into the vascular organs in the plant. Also, many of these micronized compounds are complex compounds such as carbonates (limestone) and phosphates (tricalcium phosphates like rock phosphate), which are not likely to be assimilated and transported throughout the plant’s vascular system because substances that enhance movement within the plant are usually ion specific. Their advantage would be in a soil drench/fertigation system to be assimilated more efficiently by the roots. As the
cement-like amalgamations of minerals called duripans, fragipans, or placic horizons. These can be salt-like horizons that include an accumulation of gypsum, limestone (chalk), or miscellaneous soluble salts, some of which were applied as salt fertilizers and built up over time. Since soils hold approximately one to three inches of water per foot of depth, obviously having root systems that penetrate into the subsoil can make a massive difference in managing both flooding and drought challenges.
