Moisture status of different soils under seven mapping units of Baraigram Thana has been described. The basis of description has been compiled from Thana Nirdeshika that includes moisture storage capacity in the dry season, availability of moisture to the plant/crops. Four moisture status have been categorized. These are greater than 250 mm, 250-150 mm, 151-70 mm and less than 70 mm per 100 cm profile respectively, and shown on the moisture status map. It has been observed that in dry season most of the crops suffered heavily due to drought. Satisfactory crop yield has not been observed due to lack of proper water management practices. The study shows that siltloam (Sara) is the best suited for low cost involvement in irrigation for wheat and pulses, whereas silty clay/clay (Ishurdii/Ghior) is the least suitable. Lowest amount of irrigation for wheat and pulses is required for all soils during the period of 15th November to 5th March. Adapting Thana Nirdeshika technology, large area of single crop land can be converted into at least double cropped land and command area of irrigation can be increased following proper water management practices.
