SOIL CHEMICAL DYNAMICS ON SLOPES AROUND THE RAILWAY TRACK

Shivi Kapoor and M.P. Singh

Abstract

The present paper deals with chemical dynamics of soil on the slopes around the railway track by selecting two different study sites, I (average slope- 35") and 11 (average slope- 45') at Jaunpur. The pH of soil varied narrowly on alkaline side of both the sites (I and II). Organic carbon, total nitrogen, available phosphorus and C/N ratio had shown higher values at site- I in comparison to site II. The values were heigher at the surface layer and had shown decreasing trend towards lower depths, in most of the months. In contrast, their minimum values were obtained during summer, while maximum during rainy season. The amount of carbon, nitrogen and available prohphorus were higher at site in comparsion to site II. Analysis of variance for nutrients showed significant variation in depths (organic carbon P <0.001, P<0.01; total nitorgen, P<0.01; available phosphorus, P < 0.001 and C: N ratio P < 0.01) and between months (pH, P< 0.01; organic carbon, P< 0.001; total nitorgen, P < 0.001; available phosphorus,
