The soil quality is defined as the measurements of an essential organic and moving composition. To conserve the environment boundary with human health as well as to maintain the soils productivity are the main objective. In order to understand, it is important to differentiate between the soil heath and soil quality. The soil functions are generally related to soil quality however the living and organic stocks are of a non renewable resources, reutilizing the nutrients is presented by the soil health. Among this the Soil Organic Carbon is most important factor. In the soil SOC plays an important role in the productivity of the soil. In this research we conducted a study on the District of Farrukhabad, Uttar Pradesh by using Remote Sensing. A Sentinel-2 data has used for the analysis of Land Use and Land Cover purposes. The result concluded the highest and minimum measurement of SOC in Agricultural and waste land respectively. The main objective of this research, to describe the quality and characteristic of the soil and consider the reasons by which the soil quality get disturb, to discover the agricultural practices which directly affects the soil quality.

Abstract: Sodic land is one of the major problems that has become an extensive challenge in today’s scenario, which act as a threat to global food productivity. Detrimental climatic changes are acting as a catalyst in the development of soil salinity, thereby increasing the problem in the upcoming future and ultimately effects the unaffected areas. This paper aims to integrate information from previously published literature about the extent, expansion rate, prevailing situation and current policies for handling soil sodicity as well as evaluating the sustainability of reclaimed sodic land. Since Sodic land reclamation has been done in the Indo-Gangetic region on a great extent in many states namely Uttar Pradesh, Punjab and Haryana in India. Although, in some areas, the reversion of reclamation has been reported. Therefore, this study has been done in one of the reclaimed sites of district Raebareli of Uttar Pradesh for sustainability assessment of sodic land using remote sensing, Geographic Information system (GIS) and necessary ground information. It was found that the villages of Singhpur and Tiloi blocks of Raebareli district were greatly affected by sodicity and had shown large extent of sodicity and reversion. Keywords: Raebareli district, Sodic areas, Remote sensing, Reclamation strategies, GPS.

<p><strong>Abstract.</strong> Growth and performance of various sectors of a country largely depends on the infrastructure developed by the country. It is true about the agricultural sector also. Along with the numbers, the location of these infrastructure play a vital role in reducing cost to the farmers while utilizing the existing resources like land, water, electricity and road network to their optimum level. India is the second largest producer of fruits, vegetable and tea. Against the total production of more than 500 MMT of horticultural &amp;amp; non-horticultural produces, the total cold storage capacity is estimated at approximately 31 MMT, which is not even 10% of the total production. In view of this, a site suitability study was conducted to develop an optimum plan to locate cold storages in the state of Uttar Pradesh, a leading potato growing state. Factors considered for evolving the plan includes the site of production, i.e. region where potato is grown, road network, existing cold storage, electricity and land use. When there are various factors behind any decision-making process, it becomes a complex process. It becomes difficult to decide which factor is to be given more importance and how other factors can be compounded with each other to arrive at a decision. Analytical Hierarchy process (AHP), helps us in determining the relative importance of various factors to arrive at a decision. In view of infrastructure planning, an illustrative map indicating spatial features is vital. As is widely established, remote sensing and GIS helps to obtain such a spatial map. Remote sensing and GIS was used to generate maps of the factors involved. AHP was used to develop weights of the factors in relation to each other to generate a map showing site suitability of places for developing cold storage facilities.</p>

Owing to increasing pressure of population there is an excessive demand of lands both in agriculture and non-agriculture purposes. This has resulted in vast stretches of waste land such as degraded land, soil salinity, water logging, desertification, soil erosion etc.; decrease in per capita cultivable land beside ecological imbalances. The pilot studies were carried out by NRSA and evaluated by different experts, and it was decided that the waste land maps on 1:50000 scales depicting the village boundaries were considered to be adequate for reclamation purpose. At present, the new techniques like remote sensing and GIS are used to delineate waste lands, faster and also produce better results. Current study, choose the study area of Gadilam river sub basin falling in Cuddalore and Villupuram districts. Gadilam is one of the sub-basin of Ponnaiyar basin. Main goal of the study examined the role of remote sensing and GIS for the identification of wasteland and to convert the wasteland into fertile land. Study conducted, and various data collected at different levels related to rainfall, control well details, water quality etc. Satellite imagery of the study area is also collected and interpreted. Furthermore, the maps like geology, soil are also collected. Geomorphology, land use, lineament, waste land were generated from satellite imagery. By overlaying the various thematic maps, wastelands and wasteland categories are identified. With the help of ground water wastelands of this study area is to be converted into fertile land.
