In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water. From a gardening point of view, waterlogging is the process whereby the soil hardens to the point where neither air nor water can soak through.
Waterlogging or water logging may refer to: Waterlogging (agriculture), saturation of the soil by groundwater sufficient to prevent or hinder agriculture; Waterlogging (archeology), the exclusion of air from an archeological site by groundwater, preserving artifacts; Underwater logging, the process of harvesting trees that are submerged under water
Agricultural water balances are also used in the salt balances of irrigated lands. Further, the salt and water balances are used in agro-hydro-salinity-drainage models like Saltmod . Equally, they are used in groundwater salinity models like SahysMod which is a spatial variation of SaltMod using a polygonal network.
waterlogging and drainage problems in villages, agricultural lands, and along roads - with mostly negative consequences. The increased level of the water table can lead to reduced agricultural production. shallow water tables - a sign that the aquifer is unable to cope with the groundwater recharge stemming from the deep percolation losses
In the resource-poor drylands of the Sahel region of Africa, irrigation systems and chemical fertilizers are often prohibitively expensive and thus uncommon: so increasing or maintaining crop yields in the face of climate change depends on augmenting the region's extant rainfed agriculture systems to "increase water storage within the soil and ...
Such a system is therefore called a checked, or controlled, drainage system. More usually, however, drainage systems are meant to function as regularly as possible to prevent undue waterlogging at any given time and it is this regular drainage system that is most often employed. In agricultural literature, this is sometimes also called a ...
Agroecology is defined by the OECD as "the study of the relation of agricultural crops and environment." [2] Dalgaard et al. refer to agroecology as the study of the interactions between plants, animals, humans and the environment within agricultural systems. [3]
Agroecosystems are the ecosystems supporting the food production systems in farms and gardens. As the name implies, at the core of an agroecosystem lies the human activity of agriculture . As such they are the basic unit of study in Agroecology , and Regenerative Agriculture using ecological approaches.
