Abstract
The agriculture sector on the whole planet has been subjected to abrupt climate changes, sudden floods and continuous drought. The nutrition of the planet is indangered taking into account the rate of population growth combating with water resources scarcity on some places. There is a need of developing water efficient technologies and improving their management. The MOHID-Land model has been developed in 2018 and simulates the full soil-water-plant-atmosphere transfer system and can help the improvement of agricultural water management. The current paper discussed the simulation of the soil water dynamics of drip-irrigated tomatoes cultivated in the Experimental field of the Agricultural University – Plovdiv, Bulgaria. The data by the simulations has been compared with experimental data obtained at three soil depths.
