Influence of biochars and silica on K fractionations and release into CaCl2, HCl and oxalic acid in a calcareous soil
Abstract The amount of potassium (K) in arid calcareous soils is sufficient; however, insufficient K fertilization, along with competition between K and calcium (Ca) for absorption has led to reported deficiencies. This study investigated the effect of sheep manure and rice husk biochars produced at...
