Estimating water use efficiency under conventional and conservation soil tillage practices at Gairatdin farm in Karayuziak district of Karakalpakistan
The studies on “Water use efficiency under conventional and conservation soil tillage” has been conducted in 2015 in Karayuziak district of Karakalpakstan jointly, by ICARDA and IWMI. The report summarizes the main findings of the study. The main objective of the study is to analyze the impact of soil conservation tillage (direct sowing) on soil physical and chemical properties. According the research program in 2015 the main activities were as follows: study of changes in soil bulk density in 0-100 cm soil layer under conventional and direct sowing methods; study of dynamics of groundwater depths and salinity; soil moisture budgeting; monitoring and recording all farming practices; study of changes in NPK; phenology study; study of irrigation regimes of fodder crops under furrow irrigation.
