Extensive use of fertiliser affecting land fertility: Expert

Due to extensive exploitation and imbalanced use of fertiliser over the years, the soil health fertility of agriculture land is constantly declining. Ambala has 1.17 lakh hectare of cultivable land and the presences of nitrogen and zinc have been found low in 100 per cent of agriculture land here.

The availability of potash and sulphar are low to medium while the presence of phosphorous is medium.

The trend of taking continuous crops have exhausted the key nutrients from the soil and the agriculture expert fear that if the trend was not changed, the fertility of the agriculture land would go further down in coming years and it would further increase the cost of production.

Guru Prem, subject matter specialist (soil and water management) at Krishi Vigyan Kendra Tepla, said, “Trend of taking continuous crops have exhausted the key nutrients from the soil and it is not getting any time to recover. In order to take higher yield, the farmers have been using chemical-based fertilisers and no attention has been paid towards the bio-fertilisers. Besides, the stubble burning is also leaving a bad impact on the health of soil. If the farmers stop burning the paddy residues, the organic carbon content of the soil would improve in three years.”

“If the farmers want to keep taking higher yield in the coming years too, they have to adopt diversification. Paddy can be replaced with maize and a crop of summer moong can be taken between wheat and paddy. The farmers must use fertiliser as per the recommendations only,” he added.

Rakesh Kumar, spokesman, Bhartiya Kisan Union (Charuni), said, “Diversification is the need of the hour and farmers are ready to shift. We understand that continuous trend of taking crop is leaving a bad impact and the quality and taste of the produce is also decreasing. Besides, the decreasing water table is also a matter of concern for us but the government has not been able to create a favorable scenario where the farmers can get remunerative prices for other crops. The government policies for diversification remain on papers only.”

“There is a need to educate the farmers and if the government assures to purchase the entire stock farmers would go for other crops breaking the wheat and paddy cycle,” he added.
