Dilute hydrochloric acid as an extractant for available zinc, copper and boron in rice soils
Because zinc deficiency is a widespread disorder of wetland rice and copper deficiency may occur with it, 0.05M HCl was compared with 0.1M HCl, EDTA and DTPA as an extractant for available zinc and copper. It was...
