Random use of chemical fertilisers and continued cultivation of the same crop on the same plot of land without interval and non-rotation of crops are steadily destroying the fertility of arable land in the district.
Narsingdi Department of Agriculture Extension deputy director Shovon Kumar Dhar held a meeting on Monday at his office conference room with concerned persons.
He said at the meeting that the cultivators of the district have little knowledge about the soil components. They use the chemical fertiliser haphazardly and unnecessarily to obtain maximum production destroying the production capacity of the soil.
He said most of the farmers in their cultivable lands here are using twice or thrice in yielding crops in a year and chemical fertilisers are using in a big way without any planned consideration. As result the production capability of cultivable land throughout the district is decreasing day by day.
Dhar also said that there is now a a very few member of cultivators of the district rarely use organic fertilisers including cow dung and water hyacinth which possess some capacity to retain the production capability.
The deputy director Suggested that the cultivators should apply chemical fertiliser after proper soil testing and also in consultation with the concerned agriculture officers and possible application of organic fertilisers in place of chemical ones to retain as well as to increase the production capability of the soil.
He also advised the farmers to cultivate Dhancha at their cultivable land every after three or four years. Dhanchas are important green fertilisers of the crop land. Otherwise the yielding rate will decrease further. And time will come in the near future when yield will fail to meet even the production cost.
