Evaluation of Soil Salinity and its Impacts on Agriculture: Nexus of RBOD-III, Pakistan

Abstract

: Agriculture is a primary economic activity of man since long period; agriculture is a huge platform to provide the jobs in this sector. As agriculture simply financial records for 4.2 % of direct service in developed nations, at present employs over 52 % of the labor force in the Africa, and 59 % in Oceania. In this sector employs over 1.3 billion people all over the world or near to 40 % of the global labor force. Over the fifty countries, agriculture employs half of the total population and even 75 % in the pitiable nations.Soil is a backbone of economy of an agricultural country, which increases not only the GDP but also provides the childhood and source of income in rural areas. Agriculture of any region depends upon the Soil fertility, it is natural resource which provides the food and helps to maintain ecosystem and supportsus to control on climate change. Soil salinity is a disease or cancer of soil, by this disease annual production of different crops and fruits are reducing day by day. District Kamber-Shahdadkot is also facing this disease due to the construction and mismanagement of Right Bank Outfall Drain-III (R.B.O.D-III). A six kilometers long belt of Kamber-Shahdadkot along the both sides of RBOD-III is webbed by the soil salinity. Where, farmers are seeking for a grain of rice and wheat. For the recuperation of soils fertility, a scientific experience was done in laboratory on the three parameters pH, Electric Conductivity (E.C) and Total Dissolved salts (TDS
