The main difference with the classification published by Richards in the USDA Agriculture Handbook No. 60, 1954 [4] is that the classes are narrower with steps of 2 dS/m instead of 4. Maas–Hoffman model fitted to a data set. In this example the crop has a salt tolerance (threshold) of ECe=7 dS/m beyond which the yield declines.
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]
It resorts under the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA) and is located in Riverside, California, U.S.A. The mission of its staff is to develop, amongst other, new knowledge and technology for crop production on salt-affected lands. [1]
International Center for Biosaline Agriculture (ICBA) is an international, not-for-profit applied agricultural research center with a unique focus on marginal environments. [1] It identifies, tests and introduces resource-efficient, climate-smart crops and technologies that are best suited to different regions affected by salinity , water ...
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]
In the 20th century, a surge in technology resulted in an increase in agricultural biotechnology through the selection of traits like the increased yield, pest resistance, drought resistance, and herbicide resistance. The first food product produced through biotechnology was sold in 1990, and by 2003, 7 million farmers were utilizing biotech ...
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.
Arid regions constitute about one third of the Earth's land area. Seawater greenhouse technology aims to mitigate issues such as global water scarcity, peak water and soil becoming salted. [1] The system uses seawater and solar energy, and has a similar structure to the pad-and-fan greenhouse, but with additional evaporators and condensers. [1]
