Call for increasing use of organic fertiliser to boost soil health, productivity
RAJSHAHI, Oct 18 (BSS): Substantial and sustainable uses of organic fertilizers in the farming fields is important for boosting its health and productivity which is imperative for feeding the country's gradually rising population.
Plant and animal waste based fertiliser has a vital role towards protecting the soil nutrients which are being declined due to various natural and manmade catastrophes. There is no alternative to protect the soil nutrients from further declining trend.
The observations came in a daylong workshop on "Uses of Organic Fertilizer in Protecting Soil Health" held in the NCDP conference hall of Department of Agriculture Extension (DAE) in the metropolis on Monday.
Department of Agricultural Extension (DAE) and Earth Lover Fertilizer Limited jointly organized the workshop with the main thrust of disseminating ideas and modern technologies among the stakeholders on how to promote organic fertiliser.
Fazlur Rahman, Additional Director of DAE, addressed the workshop as chief guest saying organic matter improves the chemical and physical properties of soil like its structure by acting as binding agent and the good structure enhances a favourable air-water status of soil from which plant and micro-organisms can take air, water and nutrient elements.
Organic elements enhance microbial activity by serving as energy source and the microbiological transformations like nitrogen and sulfur mineralization side by side with improving physico-chemical properties including the water and nutrient holding capacity.
With Deputy Director of DAE Dev Dulal Dhali in the chair, Agriculture Officers Motaleb Hossain and Monzure Maula and Regional Officer of Agriculture Information Service Abdullah Al Kafi also spoke.
During his keynote presentation, Khairul Abrar, Market and Supply Chain Specialist of Earth Lover Fertilizer Limited, said disproportionate use of chemical fertilizers and harmful pesticides for repeated crop harvesting is being blamed for the continuing soil nutrients decline.
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.
Agriculturist Abrar said soil test based balanced fertilization has great scope to overcome the crisis through restoring plant nutrient in the soil. Depletion of soil organic matter triggers nutrient mining together with negative balance aggravating soil fertility and soil degradation declining crop productivity in particular.
