基本説明
Links modern aspects of water transport in soil and plant with water use and crop production and derives consequences for soil and crop management.
Full Description
In many regions of the world, water is scarce. This causes a problem in plant production, as plants rely on water stored in the soil to meet their needs; thus it is the principal factor limiting crop production. Water Dynamics in Plant Production describes the basic scientific principles of water transport in the soil-plant-atmosphere continuum, explains the linkage between transpirational water use and dry matter production and presents various agronomic strategies to adapt to climate water shortage.
