Abstract:
Various factors, including salinity, alkalinity, erosion, and others, contribute to land degradation, which is a serious problem for agricultural output. For identifying, analysing, mapping, and keeping track of land degradation, remote sensing and geographic information systems (GIS) are important tools. A study was undertaken in the Ballia district of Uttar Pradesh to map the spatial variation in physico-chemical properties of soil and correlate land degradation with climatological and anthropological factors. The study was conducted on soil assessment under special monitor and mapping of degraded soil of Ballia district, UP reference to GIS and Remote sensing conducted during the year 2018-2020 at Department of Soil Science and Agricultural chemistry, with an objective to assess and monitor land degradation dynamics using geo-spatial technology in Ballia District of Uttar Pradesh. Using the Global Positioning System, 77 soil samples were taken from Ballia district of Uttar Pradesh. Correlation studies to study the relationship between two dependent variables. The statistical software IBM SPSS (version-20), was used to analyse the association between the chemical characteristics of the soil and the amount of plant nutrients that are present in the soil. With "r" values of -.604 and - .522 respectively, the correlation coefficient (r) of pH demonstrated a substantial negative association with the amount of accessible P and Na. The EC demonstrated a substantial negative association with available P and Na, with r values of -.497** and -.232* and respectively and positive relation with available K with "r" values of .618**. Organic carbon having a negative relation with available S ("r" value -.316**).
