Abstract:How to decrease and slower fixation of phosphorous in soil,and how to recycle potential phosphorous in soil,were very important to help solving these problems which were found in agriculture,such as economy,environment,resource,and so on.This paper summed up the latest research achievements at home and abroad about humic acid and modified lignin,which were mainly focused on applied research and mechanism research of improving use efficiency of phosphorous and reducing environmental risk of phosphorus.At the...
Keywords:Humic acid  Modified lignin  Phosphorus availability  Research advance
