Abstract

The importance of fertilizers was expressed as far back in 1563 by the french naturalist Pallissy that salts form on the basis of life and growth of all crops. German chemist Glouber (1656) proved that addition of salt petre to soil markedly increases the yield of crop. Role of N2 in the life of plants was elucidated even much latter. Original Ideas concerning aerial nutrition of plants was set forth by M.V. Lomonosov in 1753. The roots of Luxuriant trees in barren sand is manifestation that their succulent leaves receive copious nourishment from air. Lavoisier in 1775 discovered that plants take up substances from surrounding air water and mineral kingdom. Necessity to fertilize "bad" soils where fertilizers act as agent enabling conservation of moisture in the soil and improving its structure and to neutralize it's acidity or promote decomposition of the organic matter present there.


                        Nitrogen accumulated in the soil by Leguminous crops. Introduction of clover (or other legumes) into crop rotation improves the N2 balance and leads to substantial increase in crop yields by taking N2 from air. The amount of 'C' in the crop has nothing to do with its content in manure the source of 'C' for plants being atmospheric CO2 Liebig formulated the law of minimum That the crop size depends on the amount of minimum (i.e. the most deficient) factor.


If N2 or Zn is deficient in cultivation of a crop, no matter how much P, K and other nutrients are added they will not increase the crop yield. In 1858 Knop and Sachs succeeded in bringing plants grown on artificial nutrient media with supply of mineral salts to full maturity.
