Activities of INM (Integrated Nutrient Management) section


The declining crop production due to repeated cultivation on the same plot of available flat land and terraces in Mizoram is attributed to deficiency of major plant nutrients like Nitrogen, Phosphorus and Potash, and also of one or more micronutrients viz Calcium, Magnesium, Sulphur, Iron, Manganese, Boron, Zinc, Copper, Molybdenum, Chlorine and Selenium in the soils. Heavy rainfall area with hilly terrain like Mizoram also naturally lack Calcium and Magnesium as a result of leaching, and the soils in most part of the state are acidic where beneficial bacteria in the soils became deactivated to supply nutrients to the plants.

INM section is working on strengthening and upgradation of existing soil testing laboratories, setting up of new static and mobile soil testing laboratories to cover every district under NPMSF (National Project on Management of Soil Health & Fertility) .Farmers can thus easily access these laboratories to have a clear knowledge of his soil. Fertilizers, manures and soil amendments will be applied judiciously based on soil test results. Step is also being taken to provide on line Soil Health Card where details of soil with recommended dose of fertilizers will be recorded for every farmers.

Accordingly, priority is also given for training of farmers, staff of soil testing laboratories and also for demonstration programme to promote Integrated Nutrient Management under NPMSF.

At present, 1(one) Static Soil Testing Laboratory and 3(three) Mobile Soil Testing Laboratories had been set up where Static Laboratory is set up in Aizawl District, and MSTLs are stationed as follows:-


1. Aizawl- to cover Aizawl, Mamit & Kolasib District

2. Serchhip-to cover Serchhip, Champhai & Lunglei

3. Saiha-to cover Saiha & Lawngtlai District


Objectives :


1. To promote Integrated Nutrient Management (INM ) through judicious use of Fertilizers, including secondary and micro nutrients, in conjunction with organic manures and bio-fertilizers, for improving soil health and its productivity.

2. To strengthen soil testing facilities and provide soil test based recommendations to farmers for improving soil fertility and economic return to farmers.

3. To upgrade the skill and knowledge of Soil Testing Laboratory staffs / Extension workers and farmers and their capacity through training and demonstration on farmers fields regarding benefits of balanced use of fertilizers.

4. To ensure use of quality fertilizers through Fertilizer Quality Control Laboratory
