The Use of Organic Waste in Sustainable Water Management Under the Conditions of Dry Areas: Field and Modeling Study

Abstract Organic waste poses a threat to the environment in event of its repeated use; however, this study, we converted it into useful and environmentally safe source fertilization. In addition fertilization ability, exhibited good ability reduce water stress cultivated plants area which irrigation is lacking are suffering impact climate change. Two field experiments were conducted during 2019/2020 2020/2021 seasons study effect regulated deficit strategy organic N-fertilization ratio wheat cultivation. The majority studied characteristics slightly higher when was 75% FI as compared 100% FI. When using nitrogen mineral fertilization, at 50% mineral, possible irrigate scenario, productivity increased by 28.5% 2019/2020, 56% 2020/2021. model simulated two relatively well. summary, modeling results indicate that use sustainable management dry areas has various benefits, including yield reduced chemical fertilizers up 50%. This replaced with fertilizer produced from compost agricultural waste, abundant on all farms. These additional benefits increase income for farmers, environmental pollution.
