STUDIES ON THE CROPPING PATTERN AND SOIL BASED COMPUTERIZED FERTILIZER RECOMMENDATIONS IN THE GANGETIC SOILS OF BANGLADESH (Pages : 39 - 43)
M.H. KABIR AND M.A. JABEDThe results obtained from the studies done on the cropping pattern and soil based fertilizer recommendations show that the fertilizer recommendations given by different agencies for farmers as per soil properties made during the last decade deviated by more than 44-65% for rice-cereal grain based cropping patterns. The study areas included Gangetic Alluvium including AEZ-10 Active Ganges Floodplain, AEZ-11 High Ganges Floodplain (FP), AEZ-12 Lower Ganges FP, AEZ-13 Ganges Tidal FP, AEZ-14 Gopalganj-Khulna Peat Basin, AEZ-15 Arial Beel, AEZ-12 High Ganges FP, and attached AEZ-8 Yong Brahmaputra Jamuna FP and AEZ-9 Old Brahmaputra FP transition soils The work was done after detail analysis of the SRDI-DAE database and data of primary data collection from about 2000 soil samples representing Nowabganj and Gournadi Upazila. The summarized findings of the studies were shared with 50 dealer farmers of which 78% of the dealer-farmers told that they were using fertilizers which quantities are more by about 20% than what is recommended by the DAE agencies. Nawabganj Upazila soil potentials and crop productivity decreased by 37% when compared with the data of last decade. The findings directly indicated the essentiality of doing more researches detailing out the accurate diagnosis of soil fertility problems by field testing of soils and making yield target based computer software based fertilizer recommendations as found workable in this research.
