FERTILIZER FAQL

Initial writing by Kay Klier, using materials from a wide variety of sources. Primarily written from the point of view of NPK. Needs work on using green manures and cover crops as nutrient sources, since I mainly use them to add organic matter.

MICRONUTRIENTS

The FAQ was clearly intended for rec.gardens, and not for misc.rural, but it might be useful to add that boron is an important element in assuring growth of forage legumes like alfalfa and ladino clover.

One other mineral which can be important to the health of animals fed on forage is selenium. The soils in many areas of the United States are low in selenium; animals raised on hay or pasture from these soils can suffer from selenium/vitamin-E defficiency (White Muscle Disease), a chronic muscular dystrophy that ultimately affects the heart muscles. The condition can be relieved by injections of vitamin-E and selenium, or by diet supplements. I don't know whether selenium can be added to deficient soils.
