Effects of irrigating manure water from a scaled dairy farm on soil physicochemical properties and microbial communities
Irrigating manure water may realize utilization,but its effects on soil environment still need to be figured out.This study set up a completely randomized block design experiment with 4 irrigating amounts of 0,0.32,0.64 and 0.96 t/m2 to analyze the effects of irrigating manure water on soil physicochemical properties and microbial communities.Results showed that irrigating manure water could increase soil nutrients and crop biomass.The most suitable irrigating amounts should be 0.64 t/m2,which had the least effect on soil microbial community abundance and diversity,too.The dominant bacteria Skermanella could fix nitrogen so as to reduce nitrogen loss,and Bacillus could secrete cellulase to degrade cellulose.Ascomycota was the most dominant fungus.It could help to degrade cellulose and lignin.
