Salts dissolved from the soil accumulate at the soil surface and are deposited on the ground and at the base of the fence post. Saline incrustation in a PVC irrigation pipe from Brazil. 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 ...
The first environmental effect is increased crop growth, such as in the Rubaksa gardens in Ethiopia The irrigation that grows crops, especially in dry countries, can also be responsible for taxing aquifers beyond their capacities. Groundwater depletion is embedded in the international food trade, with countries exporting crops grown from ...
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
As a model organism, the Arabidopsis thaliana response to salinity is studied to aid understanding of other more economically important crops. High concentration of salt in the soil has negative effects on plants. For example, it reduces the yield that crop plants can produce in 7% of the land. [1]
The salt level is often taken as the soil salinity or the salinity of the irrigation water. Salt tolerance is of importance in irrigated lands in (semi)arid regions where the soil salinity problem can be extensive as a result of the salinization occurring here. It concerns hundreds of millions of hectares. [2]
Biosaline agriculture is the production and growth of plants in saline rich groundwater and/or soil. [1] In water scarce locations, salinity poses a serious threat to agriculture due to its toxicity to most plants. [2] Abiotic stressors such as salinity, extreme temperatures, and drought make plant growth difficult in many climate regions. [2]
Saline water can be used for agriculture. [26] Soil salinity can vary between extremes in a relatively small area; [27] this allows plants to seek areas with less salinity. It is hard to determine which plants can grow in soil with high salinity because the soil salinity is not uniform, even in small areas. [27]
Dryland salinity is a natural process for soil, just like other processes such as wind erosion. Salinity degrades land by an increase in soil salt concentration in the environment, watercourse or soil in unirrigated landscapes, being in excess of normal soil salt concentrations in dryland regions.
