Impact of Different Amendments and Micronutrient Mixture on Biological Properties of Sodic Soil
نویسنده
چکیده
Sodic soils have low organic carbon content, microbial load and their activities which were the biological indicators of soil health. Soil organic carbon is the kay factor which derives the soil functions. A field experiment was conducted to study the effect of different amendments and micronutrient mixture on soil biological properties. Gypsum+GM, DSW (distillery spent wash) and GLM (Glyricidia) were used as amendments. Application of amendments reduced the pH and ESP of the soil and thereby improved the physico-chemical properties of sodic soil. The microbial population, organic carbon status and enzyme activites were also improved on reclamation of sodic soil over control (without any amendment) and DSW treatment found superior to other treatments. Grain and straw yield was increased on application of amendments and micronutrient mixture. Significant response was also observed for micronutrient application in sodic soils. However, the degree of response varied with kinds of amendments.

The main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (SOM) and lowavailability of macro and micro-nutrients. The effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (USWCS) on the chemical properties of a saline-sodic soil was investigated. The experimentwas conducted using a randomized complete block des...
