Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
Normally, the salinization of agricultural land affects a considerable area of 20% to 30% in irrigation projects. When the agriculture in such a fraction of the land is abandoned, a new salt and water balance is attained, a new equilibrium is reached and the situation becomes stable.
Secondary salinity is a direct result of human interaction with the land, during development, agriculture and irrigation. Certain land practices have led to changes in the natural structure of the biosphere resulting in excess salting of the land, waterways and soils; thus having detrimental effects on biodiversity and the lands' productivity.
One of the first studies made on soil salinity and plant response was published in the USDA Agriculture Handbook No. 60, 1954. [4] More than 20 years later Maas and Hoffman published the results of an extensive study on salt tolerance. [5] In 2001, a Canadian study provided a substantial amount of additional data. [6]
Texas' water infrastructure, such as dams, pipelines, and reservoirs, is aging and often not equipped to handle modern water management challenges. Leakage and inefficiencies exacerbate the problem.
to mitigate the adverse effects of shallow water tables and soil salinization, some form of watertable control, soil salinity control, drainage and drainage system is needed as drainage water moves through the soil profile, it may dissolve nutrients (either fertilizer-based or naturally occurring) such as nitrates, leading to a buildup of those ...
On WFAA's "Inside Texas Politics," Texas Department of Agriculture Sid Miller said Texas is running out of water and lawmakers need to react soon.
The cattle business in Texas is worth an estimated $15.5 billion, making it by far the most profitable agricultural commodity in the state, according to the state’s Department of Agriculture.
