abstract: Current priorities in the Soil Fertility and Chemistry subprogram are similar to those discussed at the last In-House Review. We attach greatest emphasis to research on nitrogen, but phosphorus is gradully being given more attention. The major changes in the supprogram over the past two years have involved experimental approaches; these will be discussed.  Research on nitrogen has been subdivided also into areas of different priority, based on both the need and the probable time -frame of the research needed. Studies of the efficiency of fertilizer nitrogen have been given greatest priority. In out cooperative project with IFDC, major achievements to data are the demonstration that fertilizer-N can be used effectively by cereals particularly sorghum in the ICRISAT environment provided that good fertilizer and agronomic management techniques are used; the expertize in the use of 15N has given a preliminary insight into the extent of losses. Residual fertilizer-N had only low availability to a succeeding crop. A separate assessment of our fertilizer-N experiments over the past 6 years has been provided us with evidence to extend Dr Kanwar's comparision of the importance of "Hunger vs Thirst" in SAT soils: on Vertisols with rainfall as assured as the ICRISAT environment (or better), contraint than the oft-quoted variabilty in rainfall
