Résumé partiel
Soil is the backbone of India’s agro-economy. The limited arable land contributes about 40 per cent towards Gross National Product (GNP) and provides livelihood to about 70 per cent of the population. It is, therefore, very important to regard the cropland and its soil as a scarce resource, whose protection is essential to meet the most basic needs of mankind that is, agricultural products. It is a well-known fact that the population expansion will lead to the contraction of arable land in the coming decades which, in turn, may disturb the ecological balance resulting in to the beginning of the process of desertification and hence, a decrease in soil productivity. Further, the extensive use of pesticides, insecticides, and inorganic fertilizers may also change the soil characteristics leading to decrease in soil fertility. The study area of Mathura district lies between North latitude 27° 17’ to 27° 58’ and East longitude 77° 18’ to 78° 12’ and falls under the Survey of India (SOI) topo-sheet numbers 54E and 54F on 1:250,000 scale and 54E/5, 54E/6, 54E/7, 54E/9, 54E/10, 54E/11, 54E/12, 54E/13, 54E/14, 54E/15, 54E/16 and 541/2, 541/3 on 1:50,000 scale. The study area is a part of Indo-Gangetic Alluvial Plain, and the soil of this district are alluvium and argillaceous in nature. The basic framework of the soil development i:n the study area is constrained by lithological disposition of the geological formation, physical features and landscape pattern. Besides, the disposition of ground water in the aquifer system has controlled the soil profile and in some areas water-logging has contributed to soil degradation by development of holomorphic zones. The study area covering a geographical area of about 3797 sq. km. with gentle slope from north-west to south-east, is irrigated by tube- wells, canals and their distributaries, and minors. The Yamuna river is the main river, which flows through the study area and divide the district into two physical units : the eastern and the western tracts. Physiographically, the general slope of the study area is from north-west to south-east. The maximum elevation is about 178m above MSL near Kotban in Chhata tehsil and the minimum is 171.6m above MSL near Jalesar road, Sadabad tehsil. The study area lies in the basin of Yamuna river and is more or less plain except for few isolated hillocks on the western part of the area. Large area is subjected to fluvial action up to Mahaban and in its onward course river becomes more closely confined between its bluffs, the strips of cultivable land on either sides growing more narrow and precarious. Environmentally, the study area lies in the semi-arid ecosystem. The climiate of the area is mainly dry, intensely hot during summer and quite cold during winter. The minimum temperature generally ranges from 7°C (January) to 26°C (May) and some times falls up to 1°C in the month of January. The maximum temperature during January is about 23°C while in June it is 45°C.
