Concentration of Some heavy metals in main irrigation and drainage canals water Bakolori Irrigation Project (BIP) were investigated from March 2019 to February 2020. Four sampling stations systematically & randomly selected the two respectively. Water samples collected monthly eight taken laboratory for analysis Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Lead (Pb) Zinc...

In recent years, electrochemical precipitation has gained interest as an alternative method for the synthesis of various minerals, including struvite, from waste streams that can serve fertilizer. Studies in lowland cultivations, specifically rice (Oryza sativa) under flood-irrigated conditions, evaluating struvite a possible phosphorus (P) fertilizer source have been limited. The objective thi...

In order to formulate a reasonable water input model for cotton fields in southern Xinjiang scientific and rational fertilization, reduce soil carbon leaching, improve sequestration capacity, an undisturbed column leaching test was used simulate the current field management method study area. Two methods, drip irrigation flood irrigation, were set up, three nitrogen fertilizer levels carry out ...

flood is considered as a major threat among natural disasters in the world. this case becomes more important and has a higher risk in urban areas due to the existence of important uses. therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. considering the development in iran has been carried out in high risk...

Flood irrigation is often applied in the arid regions of Northwest China to facilitate leaching salts accumulated soil during cotton growth previous season. This will, turn, affect temporal and spatial patterns salinity, thus germination. To reveal salinity two layers (0–20 cm 20–60 cm), so as determine optimal sowing timing, an electronic ground conductivity meter (EM38-MK2) was employed measu...

A new agricultural flood losses prediction method using digital elevation data combined with agricultural economic data is presented. The method is based on dynamically simulating the procedure of flood out. An example in Huangdunhu flood detention area, Jiangshu province of China has been given to describe how to use it to predict the incoming agricultural losses. Compared with prior methods, ...
