Fertility Of Soil: The amount of organic carbon and nutrients in the soil has decreased significantly. This report released by CSE is a matter of concern for the farmers and agriculture of the country. According to the report, the carbon level in the soil of some states has been found to be very low.
There is a worrying news for the agriculture and farmers of the country. In fact, recently CSE has released the report, which states that Indian soil (Indian Soil) in organic carbon (Organic Farming) and macronutrients (Macronutrients) is either very low or low or medium. The report states that the soils tested (SoilAbout 85 percent of the samples are deficient in organic carbon. About 15 percent of these samples have low levels of organic carbon. Whereas in 49 percent of the samples, the level of organic carbon is very low. At the same time, the carbon level in 21 percent of the soil samples is moderate. Scientists say that soils with less than 0.5 percent organic carbon are considered less fertile. Whereas land with a carbon content of 0.5 percent to 1 percent is considered fertile.
Apart from this, the report has found that 83 percent of the soil samples are deficient in phosphorus. Of this, 17 percent of soils have very low phosphorus levels, 31 percent have low levels and 35 percent have moderate phosphorus levels. At the same time, about 71 percent of the soil samples are deficient in potassium. About 5 per cent of these samples have very low levels of potassium, 14 per cent low levels and 52 per cent have moderate levels. At the same time, the soil is also deficient in micronutrients and more samples show a decrease in boron, iron, sulfur and zinc and lower numbers in copper and manganese.
There is a severe deficiency of micronutrients
According to the Soil Health Card scheme launched by the Union Ministry of Agriculture and Farmers Welfare in 2014-15, the level of macronutrients such as nitrogen, organic carbon, phosphorus and potassium in the soil is very low or low or medium level, then it is categorized as deficient. Similarly, soils with less than the prescribed level of micronutrients-boron, copper, iron, manganese, sulfur and zinc, etc. is considered sufficient.
Haryana has the lowest organic carbon content in soil
According to the report, the lack of organic carbon is almost the same in the whole country. The report said that at least half of the soil samples in 24 states and union territories are deficient in organic carbon. In seven of these states, more than 90 percent of the samples are deficient in organic carbon. The lowest organic carbon has been found in the soil of Haryana. It is followed by Punjab, Uttar Pradesh, Rajasthan, Tamil Nadu, Mizoram and Andaman and Nicobar Islands.
There is less nitrogen in the soil of these states
Nitrogen deficiency in soil is also widespread and severe. At least half of the soil samples in 32 states and union territories are deficient in nitrogen. Of these, 27 states and union territories have very low nitrogen content, with more than 90 per cent. These include fifteen states of Andaman and Nicobar Islands, Dadra and Nagar Haveli, Daman and Diu, Bihar, Delhi, Haryana, Kerala, Madhya Pradesh, Manipur, Mizoram, Odisha, Puducherry, Rajasthan, Tamil Nadu, Uttarakhand and Uttar Pradesh and Union Territories. Nitrogen is deficient in almost all of their samples.
Suggestions issued for farmers
The report also emphasized that if farmers want to cultivate for a long time, then the nutrients in the soil will have to be increased again. It has also been said that along with organic matter or biomass, the use of green manure and adopting mulching techniques can increase the amount of nutrients in the soil. Apart from this, farmers will have to make changes in the farming method like crop rotation, mix farming and inter-cropping will have to be promoted, only then the quality of the soil can be improved.
