Abstract

On the basis of soil tests carried out in the four districts of South-East. Rajasthan, the total requirement of fertilizers have been calculated as 57624.06, 36754.69 and 23238.80, tonnes of Nitrogen (N), Phosphorus (P₂O₅) and Potash (K₂O) respectively. These calculations are based on the crop pattern suggested for the area on the one hand and fertility levels of the soils on the other and this reveals that there is sample scope for the use of fertilizers in these areas so that average yield can be increased. The fertilizer recommendations for the common crops of the region have also been suggested.

Abstract

The soil fertility map showing the available nutrient status of the Chambal Commanded area has been prepared and fertilizer recommendations for various crops have been given. This map is based on the analysis of 3793 soil samples collected by random sampling of villages under the command of Chambal Project. Nutrient index values are used to indicate fertility status of soils of a Tehsil for the purpose of mapping.
