Biomass growth water plants

The role of water in the life of plants is well known. In terms of its major effects this role consists in transporting the mineral nutrition, maintenance of intracellular pressure responsible for the vertical growth of plants and, finally, participation in photosynthesis which provide the biomass growth, or plainly speaking, the crop production. 

The CENTURY model also includes a simplified water budget model that calculates monthly evaporation and transpiration water loss, water content of the soil layers, snow water content, and water flows between the soil layers. The main abiotic driver for the water budget model is the potential evapotranspiration rate, which is calculated as a function of the average monthly maximum and minimum air temperature. Near surface soil temperature is calculated as a function of maximum and minimum air temperatures, litter and standing plant biomass. The plant production model calculates potential plant production as a function of soil temperature and the ratio of actual water loss to potential water loss. Potential plant production is reduced when nutrients limit growth and the element that is most limiting for plant growth controls plant production. The nutrient...
