Study of Physico-chemical and Nutrient Status of the Soil in Chiraigaon Block, Varanasi District,

A study was transported to evaluate the soil pregnancy and their quality limits of Chiraigaon Block of Varanasi district Uttar Pradesh (U.P.) that is located at Latitude 25.3°N, and Longitude is 82.9°E and at height of 81m above mean sea level (AMSL) in the centre of Gangatic plain of Northern India. A total of 54 soil samples were composed from the farmland of six various villages of Chiraigaon Block. Physico-chemical characteristic analyses accompanied average bulk mass and particle bulk of 1.22 and 2.37 mg/m3 respectively inasmuch as water holding volume ranged from 29.80 to 51.70 %, pH categorized from 7.1 to 8.3, EC ranged from 0.18 to 1.68 dSm-1 and basic carbon content categorized from 0.21 to 0.76 % with depressed natural carbon content in 70.37% of the soil samples. Macronutrient study showed depressed to medium range for nitrogen, phosphorus and sulphur accompanying average values of 244.15 Kg/ha, 14.78 kg/ha and 10.60 mg/kg individually whereas medium to extreme range of potassium (481.7 kg/ha) and high range of interchangeable calcium (11.82 mEq/100g) and magnesium (9.89 mEq/100g) were found. Micro-food analysis accompanied low to extreme range for manganese and zinc accompanying values varying from 3.08 to 56.1 mg/kg and 0.58 to 19.62 mg/kg respectively, accompanying iron in the medium to high range (5.1 to 72 mg/kg) while usable copper (2.2 to 4.08 mg/kg) was in the extreme range in the tested samples. The current study proper to help the farmers of the study district in providing guidelines necessary for long-term soil virility management and to advance soil quality and for evolving suitable crop assortments that can grow outside any yield decline.
