Research is undertaken to develop biological and physical measures to combat soil erosion.
Studies are undertaken to investigate soil moisture conservation and the relationship between rainfall, runoff and sedimentation at the catchment scale. Research is undertaken to improve the yield and quality of irrigated crops through the design of efficient management systems for irrigation and drainage. Measures are developed to increase irrigation efficiency, considering the possibilities of using wastewater in agriculture and of reducing waterlogging and salinity risks in irrigated areas by taking proper precautions. Land reclamation techniques are also developed. Research is undertaken to protect and improve the sustainable fertility of agricultural soils.
