Soil Organic Carbon Detection &Testing Kit (SOCDTK)

Introduction

Typical soil generally contains at least 45% inorganic components, 5% organic components, 25% air and 25% water on average basis. Organic carbon plays major role in biological activity and fertility of the soil. In different parts of the world positive correlation between the amounts of organic carbon and soil fertility has been proved. Indian soil ecosystems are very dynamic due to its sub-tropical climate, resulting rapid degradation of organic matter in these soils. Soil organic carbon content up to 1.5-2.0 % increases soil porosity that supports growth of the soil microorganisms. This increases availability of different nutrients to the plant, resulting in better crop yield. Thus organic carbon is a true indicator of the soil health. Also it is true that soils with sufficient organic carbon in it definitely contains other major elements like Nitrogen, Phosphorous and Potassium in more available form.

There are difficulties to analyse organic carbon of soil regularly due to specific reagents, skills and proper setup that are available only at approved laboratories. As these laboratories are in low number farmers are unable to monitor soil organic carbon on regular basis. Soil Organic Carbon Detection and Testing Kit developed at BARC, ideally a quick, accurate and field test will be able to guide the farmer for this purpose.

Advantages

Soil Organic Carbon Detection and Testing Kit has following features

• It is user friendly as any farmer himself check the percentage of organic carbon in his field.
• It gives quick and reliable results.
• Evaluates the impact of organic carbon amendments supplemented periodically.
• It gives idea of amount of organic manure additions.
• It is economical and time saving.

Applications

This kit would be useful to great extent in agriculture sector

• Direct use by the farmer for organic carbon detection of soil before sowing of the crop and at the harvest of the crop.
• To take the corrective measures to maintain the soil organic carbon at optimum levels and evaluating the effectiveness of the organic manure supplements.
• Agriculture universities & soil-testing labs for research purpose.
