Assessment of Precise Land Levelling on Surface Irrigation Development. Impacts on Maize Water Productivity and Economics
نویسندگان
چکیده
The new technologies of surface irrigation require the adoption effective Laser-controlled precision land levelling (PLL) to reach high performance standards, with significant benefits on water saving, salinity control, crop productivity, and farmer’s income. This study aimed assess impacts PLL systems, focusing maize districts Hetao (China) Lower-Mondego (Portugal). experimental at field scale assessed evaluated on-farm under precise levelled fields well management practices. operators have been inquired improve knowledge about hiring services. design scenarios allowed explain effects size slope performance. best practice manage maintenance is an important issue guarantee a effectiveness optimization appeals application soil tillage practices monitoring elevations newest information technologies. Efficient operational guidelines support planning, schedule, operation, trained carefully adjusted equipment, are key factors improvement.
