铁、锰利用率和石灰诱发褪绿病的问题,常常与石灰性土壤有关。在印度马哈拉施特拉邦碳酸钙含量高的黑色土(变性土)上,粒用高梁普遍发生缺铁褪绿病。通过土壤处理来克服缺铁症效果很不一致。Miller等曾指出,有机肥能提供一种螯合剂,促使石灰性土壤中的微量养分保持可溶状态,从而使作物利用得更好。 Iron and manganese utilization and lime-induced chlorosis are often associated with calcareous soils. In black soil (denudated soil) with high calcium carbonate content in Maharashtra, India, grain sorghum disease commonly occurs with sorghum. Through the soil treatment to overcome the effect of iron deficiency is very inconsistent. As Miller et al. Have pointed out, organic fertilizers provide a chelating agent that helps to keep the micronutrients in calcareous soils that they are more soluble.
