Abstract
The present investigation in relation to “micronutrient status of soil in Deoli tahsil of Wardha district” was undertaken during 2018- 19. Surface soil sample were collected by systemic survey using georeferences system from Deoli tahsil of Wardha district. Total 75 soil samples were collected that represent all area. Soils of Deoli tahsil of Wardha district were studied for their physico-chemical properties, major and micronutrient status of surface soils. All the soil under study were slightly to moderately alkaline in reaction, EC values for these soils were within the safe limit. The organic carbon content in these soils showed low to medium status. The free CaCO3 content of these soils ranged from moderately calcareous to calcareous in nature. The average available major nutrient content in these soils show low to medium status for available N (150.62-319.47 kg ha-1), low to medium status for P2O5 (9.51-18.89 kg ha-1) and medium to high status for available K2O (254.55-380.45 kg ha-1). As regards with available S status it varies from 9.23 to 18.54 mg kg-1. Among the micronutrient cation content in soils of Deoli tahsil, available Fe content varies from 3.40 to 11.57 mg kg-1. Mn content varies from 4.96 to 13.80 mg kg-1. Zn status in soils varied from 0.28 to 0.82 mg kg-1.The Cu content varied from 1.2 to 2.68 mg kg-1. B ranged between 0.33 to 0.78 mg kg-1 and showing that these soils are well supplied with Cu, Mn and Fe and low to marginal in Zn and B. The correlation study reveals that availability of major and micronutrient decreases with increase in pH. The increase in organic carbon leads to increase in N, P, K, S and Fe, Mn, Zn, Cu and B. Soil fertility index worked out for major and micronutrients and showed that as per six tier system the nitrogen, phosphorus, Zn and B comes low category, S under moderate, Mn under high, whereas, potassium and Cu comes under very high category.
Description
It relates to micronutrient and macronutrient status in Deoli tahsil of Wardha district and found that Soil organic carbon, available N, P, Zn, and B are important soil fertility constraints indicating their immediate attention for sustained crop production.
