About Soils

Soils are derived from weathered parent material. If the original material was low in a particular element or non existant, so too is the resulting soil.
Soils can become depleted of minerals and trace elements which too are absorbed into the likes of meat, milk, bone, wool, vegetables and fruits, as well as the major elements, and many soils are naturally deficient in one or more of these elements.
Within a space of just a kilometre or two, soils can be radically different, with.localised deficiencies of trace elements like copper, cobalt or selenium.
Because our supply of minerals comes through the food chain, from the plants and animals we eat, and because these same minerals are essential ingredients of these same plants and animals, any that are missing can have serious implications for plant, animal and ultimately our own health.
One has to conclude then, that this is where fertilization should start.
Even though the major element solid type NPK fertilizer is required in the largest amounts, if used exclusively, sooner or later a deficiency of a minor element can occur in soils low in that particular element, and it too should be replaced.
Foliar nutrients can quickly correct a nutrient imbalance, and are by far the most effective way to apply micro nutrients or trace elements and supplement the major elements , because foliar nutrients are readily available and more easily utilized by the plant than soil nutrients.
