  • 3. Geographic coordinates: 24 00 N, 90 00 E BANGLADESH
  • 4. 6/1/2014 SRDI, BANGLADESH 4 Land includes all the natural environmental resources contained on the earth surface: soil, terrain, water, climate and weather. Arable lands are needed for sustainable agricultural systems to support a burgeoning human population in countries like Bangladesh.
  • 5. 6/1/2014 SRDI, BANGLADESH 5 Nations, village communities as well as individual land users need to make the best choices among options for the use of land in order to support development without hazard of land degradation, which would endanger sustainable production of food and other rural products. That is why land resources appraisal is needed.

Plant Nutrient Balance Sheet of Bangladesh Source: Karim, et al. (1994)
  • 27. 6/1/2014 SRDI, BANGLADESH 27 Nitrogen alone constitutes over 75 percent of the total nutrients used in Bangladesh agriculture, while the use of P and K are limited to about 6.0 and 6.6 percent only. The probable causes are high price and use of substandard phosphatic fertilizers available in the market. But the use of N-fertilizer has steadily increased which shows inappropriate/imbalance ratio of N, P205 and K20 (1:0.12:0.13). If this trend of fertilizer use continues along with intensive cropping of high yielding varieties, the productivity of our soils is bound to be seriously affected in future.

  • 29. 6/1/2014 SRDI, BANGLADESH 29 Launched on March 14, 2011 > Bangladesh has developed Digital Fertilizer Recommendation Software for Ministry of Agriculture by Soil Resource Development Institute (SRDI). > A central database covering the entire country (459 upazilas) soil sample has been developed as the feedstock of the system. > The addresses of the websites for having online fertilizer recommendation are frs.srdi.gov.bd and www.frs-bd.com, username: srdi & password: srdi (****). Digital Fertilizer Recommendation Software for MOA of Bangladesh
  • 30. 6/1/2014 SRDI, BANGLADESH 30 > To facilitate farmers selection of different fertilizers and their precise dosage for different crops through digital platforms to increase crop yield and decrease production cost. > Expected outcome: On an average rice yield will increase by 20-25 percent and other crops by 10-15 percent. > Farmers can use either of two leading mobile phone operators: Grameenphone and Banglalink platforms to have precise fertilizer recommendations by providing five basic information: name of the crop type of land name of the union upazila and district
