在自然情况和在人工条件下 ,红壤渗漏水中磷的浓度很低 ,而NO- 3-N浓度随着氮肥硝化作用的进行快速增加 .钾的浓度介于氮磷之间 .在施用NH+ 4 -N氮肥时 ,渗漏水中未见NH+ 4 -N出现 .植株和植物残体经雨水淋洗的养分是主要是钾 ,但植物残体磷溶出量也较高 .
Under natural conditions and under artificial conditions, the concentration of phosphorus in the infiltration water of red soil was very low, while the concentration of NO-3-N increased rapidly with the nitrification of nitrogen, the concentration of potassium was between that of nitrogen and phosphorus. -N nitrogen fertilization, no NH + 4 -N was found in the leaking water, while the nutrient leaching plants and plant residues was mainly potassium, but phosphorus residues in plant residues were also higher.
