There is little information on whether human urine （ALW） can be used as a nutrient source in crop cultivation. A study was conducted to explore the potential of human urine in cultivation of radish （Raphanus sativus L.）. The ALW was provided to radish in a pot trial. Comparison was with combinations of using synthetic fertilizers. Human urine contained N （0.45%）, P （0.18%）, K （0.16%）, Ca （4.25 me Ll）, Mg （5.15 me L＂t） and Na （0.36%）. The highest available nutrients N, P and K contents in soil at harvest, and the more number of leaves, tallest, root length, root yield and root diameter were from the in 3：1 ALW--three parts of ALW （human urine and one part of water used pot）. Water treatment applied in two splits compared to the recommended fertilizer rate （75：37.5：37.5 kg hal of N, P and K） and absolute control （no fertilizer and no ALW added）.展开更多

Accurate knowledge of the various elemental concentrations in wheat and its products （bran and flower） is of great importance from nutrition point of view. Wheat samples were obtained from Asir region, 900 Km southern of Riyadh, and analyzed. Up to 50 elements in wheat products were determined. It was observed that the mineral content of bran was much higher than white flour.展开更多
