The Temporal Dynamics of the Latosol Soil Potassium Content after Application of the Eight Kind of Crotalaria Green Manures
The temporal dynamic changes of the Latosol potassium after application of the eight kind of Crotalaria were studied in this paper.The results showed that: the application of different green manures on soil available potassium content was different,but the impact on soil available potassium content had the similar rules.Application of green manures in soil could to some extent increase the soil available potassium content and the soil available potassium content after application of different green manures was also different with the change of application time,the best time to increase soil available potassium is the first month.
