Effects of Salt Stress on Nutrient Cycle and Uptake of Crop Plants

Abstract

The biogeochemical cycling of elements involves the interactions between the biosphere and the surroundings in the form of cycling of elements throughout the different spheres viz., atmosphere, hydrosphere, and lithosphere. This chapter elucidates the effects of salinity stress on biogeochemical cycle and soil microorganisms that directly or indirectly affect the crop production. Nutrient uptake, primary productivity, and other biological processes are widely affected by nutrient limitation in terrestrial ecosystems. Nutrient cycling is one of the most important phenomena that occur in an ecosystem. The nutrient cycle represents the use, movement, and recycling of nutrients in the environment. Salt stress has an overall negative effect on carbon cycle which is implemented by its effect on various components of carbon cycle viz. photosynthesis, and microbial decomposers. Oxygen and water cycle or hydrological cycle are two biogeochemical cycles through which oxygen and water moves through biotic and abiotic components of earth and are essential for survival of life. © 2022 John Wiley & Sons Ltd.
