چکیده

Soil salinity/sodicity is the major problem in irrigated and rain-fed areas are a continuous threat for sustainability of agricultural production. The presence salt affected soils has been identified as process land degradation greatest cause declining productivity by causing detrimental effect on biological, physical chemical properties soil system. Therefore, objective this topic to review impacts soil- water relations plant growth dry relation their extent, distribution development so manage efficiently utilize limited natural resources under irrigation farm lands. Land salinization often found Arid Semi-Arid lands where unsuitable or with poor quality common practice. Moreover, salinity also mainly function rising groundwater tables, caused increased recharges. Soils having soluble salts solution and/or Na + ions both exchange sites exceeding certain limits that can adversely affect health disturbing biological , lower limit classified saline, sodic saline taking into consideration pH, ECe ESP. High levels have negative impact potentially lethal effects plants growth. On other hand, high sodium concentration causes sodium-induced dispersion like reduced infiltration, hydraulic conductivity surface crusting while calcium magnesium, do not because they smaller tend cluster clay particles keep be flocculated since compete same spaces bind reduce amount dispersion. affects nutrient balance interfere uptake some nutrients.

Partitioning soil-water losses in different plant populations of dry-land corn

In situ volumetric soil-water contents were measured on 11 days at 0.20 m depth intervals to 1.0 m in a field experiment with four replicates of a dry-land corn hybrid (Pioneer 3140) at plant populations of 37, 49, and 62 thousand plants haÿ1. These measurements were used to estimate total soil-water losses in each of the 12 field plots for each of the 10 measurement intervals. The area of the ...

Impacts of Land Use Change on Soil Erosion and Water Quality—A Case Study from Hawaii

The ongoing diversification of agricultural lands in Hawaii to replace sugarcane and pineapple plantations is a major challenge. It presents an interesting case study for global concerns with land degradation-land use interaction. The important question posed by this paper is: will “diversified” crops have a different impact on the natural resource base and environmental quality from earlier cr...

Soil-Tree-Atmosphere Water Relations

A process model of the soil-tree-atmosphere continuum, which treats the plant physiology, eco-physiology and vegetation structures in detail, needs to describe the dynamics of the water flow within this continuum. The concept of a soil-plant-atmosphere continuum (SPAC) (Philip, 1966) was first described by Huber (1924). In such a continuum, the removal of water lowers the water potential in the...
