As a y l result, considerable amount fertilizer has and is being used Jn the early days when land was dequuu virgin, it contained phosphorous or adequa'e plant nutrients to grow most crops that were being produced. Some fifty to one hundred years later, it was found that many of these land nutrients have been removed from the soil so that is is now necessary to replace them in order to produce a satisfactory crop. ttlTII Al.FAl.I A, the needs are primarily those of supplying phers phorous Alfalfa feeds heavily on phospnorous and needs it tit re latively large amounts in order to produce good yields.

FERTILIZE EARLY According to scientists at Utah State University, a problem has arisen in which some people will not accept the use of consumption crops if commercial fertilizer has been used. This has been brought to their mention by various food plant organizations, by organic farmers and by a series of individuals who are either uninformed or misinformed do Plants not use plant nutrients in the organic form as a popular concept of a number of people. They may be applied in the organic form, but they are converted to the inorganic form before a plant can use them. The plant cannot detect the difference between nitrogen coming from a compost heap and nitrogen be.ng supplied by ammonia nil rate The inorganic form of fertilizer is generally supplied as commercial fertilizer - ammonia sulphate, ammonia nitrate, or Research has been done on a world wide basis to study the effect of commercial fertilizers and their relationship to men and animals, and no evidence has ever been brought forth indicatthat a detrimental effect ing could be found from the use of these products. All the accounts against their use, from a health pornt of view, are completely unfounded and are based either on no information or lack of information. In order to feed the world and the nation as is being done today, it would be impossible to even remotely approach the production that is currently available with organic fertilizers. It is completely necessary that inorganic fertilizers be used. 4 o r9 vtid trodwmozli FERTILIZER all others. L. 4 F,Vi Resuts in 7 day |
