Application of organic fertilisers like composts, vermin-composts and green manure can increase crop production by 15 per cent reducing use of chemical fertilisers side by side with substantially improving soil health
According to experts, demand of organic fertilisers and green manure has been increasing as the farmers purchase those for applying in crop fields to get increase crop output, revive soil health and fertility by adding necessary soil nutrients.
Meanwhile, production of organic fertilisers in homesteads under the ‘Ekti Bari, Ekti Khamar (EBEK) and other projects has already become a profitable venture bringing fortune to hundreds of small and marginal farmers in Rangpur agriculture region.
Talking to BSS, Horticulture Specialist of the Department of Agriculture Extension (DAE) Khondker Md Mesbahul Islam said application of organic and compost fertilisers could increase crop production by up to 15 per cent along with improving environment.
“Production of organic fertilisers has been increasing in all five districts under Rangpur agriculture region where farmers have now set up over 72,000 pits and heaps of compost, quick compost, vermi-compost and farmyard compost fertilisers,” he said.
Extension Agronomist Anarul Haque at Dinajpur Hub of International Maize and Wheat Improvement Center said crop production might increase substantially if balanced use of chemical fertilisers along with composts was ensured adopting conservation agriculture technologies.
“The nationwide annual consumption of urea, TSP, MoP and other chemical fertilisers and pesticides would reduce by 30 per cent if production of organic fertilisers increased further ensuring its popular usages throughout the country,” he added.
Knowledge Management and Communication Specialist of Climate Resilient Agriculture and Food Security Project of World Bank Dr MG Neogi said use of organic and compost fertilisers would also improve environment, ecology and bio-diversity.
Agriculture and Environment Coordinator of RDRS Bangladesh Mamunur Rashid said organic and compost fertilisers and green manures were being produced using cow dung, wood dust, oil cake, water hyacinths, various wastages, leaves and other waste materials.
“The small and marginal farmers, poor, distressed and landless people have been earning better profits through producing compost fertilisers in homesteads under the EBEK project and selling those to the farmers throughout the year,” he said.
Former Chief Scientific Officer of Bangladesh Rice Research Institute Dr MA Mazid said growing awareness about adverse impacts of chemical fertilisers and pesticides among farmers was inspiring them in increasing production of organic and compost fertilisers.
Regional Additional Director of DAE Shah Alam said organic fertilisers could improve soil textures, fertility, increase water and nutrient storing capacities, upgrade sandy land into sandy-loamy and sandy loamy into loamy and then into clay soil in course of time.
“Side by side with increasing crop yield, adequate use of organic and compost fertilisers helps regaining lost population of extinct insecticides, earthworms, birds, fishes to maintain ecology, bio-diversity and environment,” he added.
