Current status of organic matter in the soil of Bangladesh Current status of organic matter in the soil of Bangladesh Ideal soils need to contain about 5% organic matter on a volume basis. Medium soils must contain an average of about 2.6% organic matter. Incredible but true, the amount of organic matter in the soil of Bangladesh is less than 2% on average. Soil of Bangladesh has more or less amount of organic matter according to land class. Organic matter is less than 1.0% -1.6% in low lands and less than 1.0% in very low lands. Moreover, at present about 39.41% of the land in the country has organic matter content of 1.0% or less and in 53.6% of the land it is less than 2%. About 93.28 per cent of the land in the country is deficient in organic matter. Causes of depletion of organic matter in the soil One of the long standing problems in agriculture is the depletion of organic matter in agricultural lands. As a long-term effect of unplanned cultivation, there is a shortage of organic matter in the soil of Bangladesh. If this trend continues, the vitality and productivity of the soil will decrease incredibly at some point. Other reasons for the depletion of organic matter in the soil are the accumulation of organic matter in the soil from these sources including crop residues, weeds, germs and insects, applied organic manure and non-application of water or airborne organic waste from other sources. Moreover land erosion and unplanned land cultivation. Do not follow the cropping pattern. Deficiency of organic matter occurs when balanced amount of fertilizer is not used. Intensive use of land indiscriminately. Spreading lots of weeds. Use of crop residues and dung as fuel. Do not use organic fertilizer regularly. When soil acidity is not controlled, there is a shortage of organic matter.
