BSS, Rajshahi :
Substantial and sustainable uses of organic and compost fertilizer in the farming fields can help protecting the soil nutrients from further declining trend.
Plant and animal waste based fertilizer has a vital role towards making the soil nutrients being declined due to repeated crop farming as revealed by the soil scientists and agriculture researchers while talking to BSS here separately.
Besides wide-ranging cultivation of high yielding and hybrid varieties of different crops and vegetables, disproportionate use of chemical fertilizers and harmful pesticides for repeated crop harvesting is being blamed for the continuing soil nutrients decline.
They also observed that lesser use of organic matter and little or no use of leguminous green manure and bio- fertilizers have also been detected as the degradable factors.
Mahabubur Rahman, Scientific Officer of Regional Laboratory of Soil Resource Development Institute, said here that soil test based balanced fertilization has great scope to overcome the crisis through restoring plant nutrient in the soil.
Quoting his research findings he said depletion of soil organic matter triggers nutrient mining together with negative balance aggravating soil fertility and soil degradation declining crop productivity in particular.
He mentioned that optimum level of organic matter is a must for building and maintaining positive soil properties and normal soil ecosystem that supports plant growth. ]
Sufficient organic matter is also imperative for creating a positive soil environment from which plants can uptake nutrients from applied chemical fertilizers.
