AICRP-LTFE Akola

This experiment has been added by the GLTEN Curators using existing published sources.
Objective
To study the long-term impacts of fertilizers on soil quality, crop productivity and sustainability.
Description
The introduction of high yielding varieties, irrigation and improved fertilizers accelerated the mining of nutrients from the soil. To sustain the productivity it was essential to maintain the supply of nutrients to the soil. The All India Coordinated Research Project on Long-Term Fertilizer Experiments (AICRP-LTFE) in September 1970 at 11 centres to understand the long term impacts of fertilizers on productivity, soil quality and the environment.
