7. Soil fertility status of wheat growing areas of union council cattle farm, Tehsil Jhat Pat, Balochistan

Abstract

For sustainable agriculture, optimum soil fertility plays an important role. Analysis of soil nutrients status with the passage of is inevitable. In order to investigate the fertility status of soil in wheat growing areas of union council Cattle Farm, Tehsil Jhat Pat, Balochistan, 30 soil samples were collected from surface soil (0-15 cm) to analyse some physio-chemical properties and nutrients status. The results of the present study revealed that 100% soils were clay loam in texture. Electrical conductivity (EC) ranged from 0.59-2.55 dS m^-1 (average 1.10 dS m^-1), 86.6% soils were grouped as non-saline (EC < 2 dS m^-1) while 13.4% samples were slightly saline (EC: 2-4 dS m^-1). For soil pH, all samples were observed moderately alkaline (7.4-8.4). Soil ABDTPA-P ranged from 0.30-49.80 mg kg^-1 (average 8.44 mg kg^-1), about 43.3% of the soils were observed high (> 7 mg kg^-1) in P. Soil ABDTPA-K ranged from 237.5-762.5 mg kg^-1 with an average value of 360.0 mg kg^-1. The K was high (> 150 mg kg^-1) in all soil samples. On the basis of present results, the EC of the soil is non-saline, P is marginal and K is high in the mentioned area. It is recommended that proper soil management, balanced fertilization and management can increase crop yield and maintain soil fertility.
