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

Abstract

A study was conducted to evaluate the soil fertility and their quality parameters of Chiraigaon Block of Varanasi district Uttar Pradesh (U.P.) which is located at Latitude 25.3°N, and Longitude is 82.9°E and at elevation of 81m above mean sea level (AMSL) in the centre of Gangatic plain of Northern India. A total of 54 soil samples were collected from the farmland of six different villages of Chiraigaon Block. Physico-chemical property analyses showed average bulk density and particle density of 1.22 and 2.37 mg/m3 respectively whereas water holding capacity ranged from 29.80 to 51.70 %, pH ranged from 7.1 to 8.3, EC ranged from 0.18 to 1.68 dSm-1 and organic carbon content ranged from 0.21 to 0.76 % with low organic carbon content in 70.37% of the soil samples. Macronutrient analysis showed low to medium range for nitrogen, phosphorus and sulphur with average values of 244.15 Kg/ha, 14.78 kg/ha and 10.60 mg/kg respectively whereas medium to high range of potassium (481.7 kg/ha) and high range of exchangeable calcium (11.82 mEq/100g) and magnesium (9.89 mEq/100g) were found. Micro-nutrient analysis showed low to high range for manganese and zinc with values ranging from 3.08 to 56.1 mg/kg and 0.58 to 19.62 mg/kg respectively, with iron in the medium to high range (5.1 to 72 mg/kg) while available copper (2.2 to 4.08 mg/kg) was in the high range in the tested samples. The current study is expected to help the farmers of the study location in providing guidelines required for long-term soil fertility management and to improve soil quality and for developing suitable crop varieties that can grow without any yield reduction.

Macronutrients for Plants Growth and Humans Health

“…Plants are living entities that require certain nutrients to grow, and thrive, including macronutrients and micronutrients ( Plants require particular nutrients to grow and thrive, including macronutrients (which are required in greater quantities) and micronutrients (Diwakar, A. K., et al 2023). The principal macronutrients are nitrogen, phosphorous, and potassium, while minor macronutrients include calcium, magnesium, and sulfur (Abbas, F., et al 2023), these macronutrients are required in large quantities by plants to carry out essential physiological processes such as photosynthesis, respiration, and growth, and maintaining a balanced supply of these nutrients in the soil is essential for healthy plant growth (Karthika, K. S., et al 2018).…”
