According to the IFFCO Field Officer, Mr C.G. Airani, the programme carried out on five plots adopting five different strategies in each field to analyse the impact of soil nutrients on paddy harvest has underlined the need for soil testing as a prerequisite, which many paddy cultivators ignored.

The strategies for demonstration plots were - local farming technique with usual irrigation and protection methods, local farming technique with application of secondary nutrients of NPK, cultivation techniques suggested by the Agriculture department, guidelines of Agriculture department accompanied by the use of secondary micronutrients. In the fifth plot, a comprehensive soil test along with its nutrients.
