LI Jie, CHEN Zhi-wen, SHI Yuan-liang, et al. Effects of Phosphorus Activator on Different Type of Phosphorus and Their Validities in Red Soil[J]. 2011, 25(3).DOI:
Different phosphorus activators(PA) were added into southern red soil of China to test their activation capability.The results showed that PA could improve available phosphorus contents in the soil effectively
and activations capability of different activators differed.Results of coeffcient analysis and path coefficient analysis showed that the activations capability order were as follows:Low-molecular weight organic acid>humic acid>sodium humate>ethyl allophanate.Meanwhile
