Assessment of Soil Quality of Different Villages in Chauth Ka Barwara Block in Sawai Madhopur District, Rajasthan

A study was conducted to assess the soil quality of Chauth Ka Barwara block in Sawai Madhopur district, Rajasthan. A total of thirty soil samples were collected at a depth of 0–15 cm. The samples were obtained at regular intervals of around 1 km, utilizing a random sampling approach. The soil samples were air dried in a shade area at room temperature, grind into a fine powder using a ceramic mortar, and filtered a 2 mm sieve and subsequent physico-chemical analysis. The results showed the bulk density (1.12–1.46 g cm-3), particle density (2.22–2.92 g cm-3), porosity (38.72–52.35%), water holding capacity (27.30-44.92%), pH (6.2–8.2), electrical conductivity (0.11–0.89 dS m-1), organic carbon (0.16–0.99%), available nitrogen (62.72–188.16 kg ha-1), available phosphorus (6.72-52.86 kg ha-1), available potassium (246.4–397.5 kg ha-1), available sulfur (1.11–12.26 kg ha-1), available calcium (1.10–25.5 meq 100-1), available magnesium(1.8–23.6 meq 100-1), available iron (1.80–7.40 mg kg-1), available manganese (1.50–8.10 mg kg-1), available copper (0.11–2.30 mg kg-1), and available zinc (0.10–4.30 mg kg-1). The analysis reveals that 43.33% of the samples demonstrate a moderately alkaline response, 6.66% produce a strongly alkaline reaction, and 26.66% present a neutral reaction. 90% of samples fall within the acceptable range while 10% exceed it marginally. The organic carbon content is classified as low at 53.33%, high at 16.66%, and medium at 30%. The study emphasizes the vital significance of soil fertility in fostering sustainable agricultural output.
