2.7 Soil Analysis
Prior to soil analysis four soil samples were collected at surface soil (0-15 cm) and sub-surface soil (15-30 cm) in each treatment. These four samples were mixed well to make a composite sample for determining the physico-chemical during 2018 and 2019 and pooled values of these two years presented. Soil pH and EC were determined through a multimeter (Eutech Instruments, Singapore) on a 1:2.5 soil-water suspension (Jackson, 1973). Post monsoon Soil moisture status was estimated using gravimetric method. Soil organic carbon, available N, P, and K was analyzed using methods developed by Walkley & Black (1954), Subbiah & Asija (1956), Olsen et al (1954) and Hanway & Heidal (1952), respectively.
