IPI activity in India

Coordination: India

The main aim of IPI activity in India is to promote "Balanced Nutrition" with emphasis on K nutrition in the main crops. This mission is carried out via research and extension activities: field experiments, demonstration plots, farmers meetings, dealers training programs, field days, workshops and conferences, publications and awards and assistance for researchers.

Refinement of K Recommendations in Vertisols

In many parts of India, vertisols exhibit adequate available potassium (K) levels, and yet crops grown in vertisols respond to application of K fertilizers. This raises several questions including:

  1. do we need to revise the method to measure available K in vertisols?
  2. do we need to revise low, medium, and high categories of available potassium for vertisols?
  3. do we also need to include the contribution of non-exchangeable K in making K fertilizer recommendations for crops grown in vertisols?

Two workshops were organized to discuss this issue and arrive at recommendations.

In 2010, we organized the IPNI-IPI-NBSS & LUP Workshop on ":Review and Refinement of Fertilizer K Recommendations in Vertisols", August 24-25, 2010, at the National Bureau of Soil Survey & Land Use Planning, Amravati Road, Shankarnagar PO, Nagpur, Maharashtra.

In 2012, we organized the 7th IPI-FAI Round Table in collaboration with IPNI on "Refinement of K recommendations in Vertisols", March 3, 2012, at NAAS, NASC Complex, New Delhi.
