Effects of Different Organic Fertilizers on Phosphorus Accumulation and Leaching Risk of Reclaimed Soil in Mining Area
In order to explore the difference of phosphorus accumulation and loss risk of different organic fertilizers in the process of reclaiming the soil in the mining area. In this experiment
the reclaimed soil of coal mining collapse in Xiaoyi City
Shanxi Province was taken as the research object
and the effect of different organic fertilizers
including poultry manure
swine manure
cow manure and chemical fertilizer
under 4 P levels (0
25
50
100 kg/hm2) after 4 years in reclaimed soil of mining area on total phosphorus
Olsen-P
Mehlich3-P
CaCl2-P
and degree of phosphorus saturation (DPS) and the relationship among them were studied. The results showed that:(1) The application of organic fertilizers increased the phosphorus content in the soil
and the greater the amount of phosphorus applied
the more obvious the impact on the phosphorus content
especially the total phosphorus
Olsen-P
Mehilic3-P in the soil
and CaCl2-P increased; Compared with non-phosphorus treatment and chemical fertilizer
the application of organic fertilizers increased the surface layer (0-20 cm) soil degree of phosphorus saturation (DPS); In general
the effects of different fertilization treatments on the soil phosphorus content showed that poultry manure ≥ swine manure>cow manure>chemical fertilizer. (2) There was a significant linear correlation between the soil Olsen-P and Mehlich3-P
Olsen-P and CaCl2-P
Mehlich3-P and CaCl2-P in each fertilization treatment. (3) Compared with swine manure
cow manure and chemical fertilizer treatment
poultry manure treatment had the greatest impact on the risk of phosphorus loss in reclaimed soil. When DPS ≥ 39.31%
Olsen-P ≥ 26.24 mg/kg and Mehlich3-P ≥ 49.06 mg/kg
the content of CaCl2-P in soil increased rapidly. Therefore
the above indexs could be used as the critical value of phosphorus loss in reclaimed soil of mining area. If these values exceed
the risk of soil P loss would increase. We need to be vigilant about the pollution of surface and underground water.
