'Soil Health Circular' ie Soil Health Card Scheme is a scheme brought by the Government of India in February 2015.
Under this scheme, farmers are given a soiled card, which is free of cost to the farmers, this helps the farmer to get a good crop by studying the quality of the soil.
This soil card also gives the exact amount of fertilizer required for the crop.
The cropped area was divided into grids of 10 ha for rainfed and 2.5 ha for irrigated and taken only one soil sample from each grid and test results will be distributed to all the farmers whose area was falling under the grid.
Soil samples are processed through standard procedures and analyzed for various parameters namely pH, electrical conductivity (EC), Organic Carbon (OC), available N, P, K, S and micronutrients (Zn, Cu, Fe, Mn & B).
The State Government will collect samples through the staff of their Department of Agriculture or through the staff of an outsourced agency. The State Government may also involve the students of local Agriculture/Science Colleges.
Soil Samples are collected generally two times in a year, after harvesting of Rabi and Kharif Crop respectively or when there is no standing crop in the field.
