Product Description

Soil fertility is the ability of soils to supply nutrients to crops in an amount favorable for their successful growth and yield.  Plants absorb nutrients and water from soil and combine them with atmospheric carbon dioxide and solar energy to synthesize living tissue.  So soil and water may be considered to be the primary resources of a nation.  Both soil and water have been misused in the past.  Intensive production of crops in soils without adequately restoring the soils' nutrients has resulted in the decline of their fertility, since soils do not have an inexhaustible store of plant nutrients.

In old and densely populated Asian countries including India, peasants have been exploiting soils since their time on earth began.  Consequently soils have become depleted in plant nutrients.  Plant nutrients have also been intensively lost through erosion and leaching from tropical soils.  So their inherent fertility is low.  It is highly essential to build up the fertility of soils or at least to maintain it to a level high enough for sustained production of food to feed the ever hungry millions, especially in developing countries.  To do this, soil fertility management is a basic necessity.
