Substantial and sustainable promotion of biogas plant has become indispensable for more production and use of bioslurry, main effluent of biogas plant, to improve soil fertility and increase crop productions, agricultural extension officials and scientists said.
They viewed enhanced use of bioslurry has enormous contribution towards reducing use of chemical fertilizers and pesticides in the farming fields which is directly or indirectly harmful for the total farming system.
An optimum use of bio-fertilizers always improve soil textures, fertility, increase its water and nutrient storing capacities, upgrade sandy land to sandy-loamy and sandy loamy to loamy and then clay soil in course of time.
Aminul Islam, a seed contract-grower of Bidirpur area under Godagari upazila of the district, said he had made his seed production activities profitable using bioslurry from his two biogas plants.
“In addition to cooking meals of our eight-member family, I have been running a cow-fattening farm with 26 cattle and seed production project on 45 bighas of land commercially with my two biogas plants simultaneously for the last one and half years,” he mentioned.
He had set up a 2.5 diameter plant with his own initiative in 2007 for meeting his domestic fuel demands. Witnessing the success, he installed another 4.8 diameter plant in 2010 for fulfilling his domestic and commercial demands through using the natural resources especially eco- friendly biogas and slurry.
Aminul said there is no doubt that bioslurry acts as the best resource of organic fertilizer. Around 80 families have set up biogas plants in Godagari upazila of the district particularly Premtali and its surrounding areas.
Biogas is not only used as fuel for cooking foods but the slurry is being used as organic fertilizer in the farming fields for boosting its production.
