چکیده انگلیسی


• Quicklime increased soil pH and bacterial alpha diversity of the acidic soil more rapidly.
• Manure improved nutrient concentration of the acidic soil more effectively.
• Copiotrophic taxa were in greater relative abundances with swine manure treatment.
• Oligotrophic taxa were in greater relative abundances with quicklime treatment.

Red soil is a kind of Ferralic Cambisol. Good hydrothermal resources but usually acidic and low base saturation make it very easy to be acidified under unreasonable fertilizer managements in agricultural area. In 1990, a series of fertilizer applications were established on a homogeneous field to investigate the soil fertility changes under different fertilizations in Hunan province, among them, long-term chemical nitrogen fertilization (NPK) induced severe soil acidification, whereas long-term chemical plus swine manure fertilization (NPKM) exhibited an overwhelming advantage in terms of nutrient concentration and bacterial diversity. In 2010, to investigate the effect of short-term quicklime and swine manure applications on the acid red soil, a remediation experiment was established on the NPK treatment. Quicklime (CaO) and swine manure (the same as the swine manure in NPKM) applications on NPK soil had different effects on remediating the soil acidification: short-term quicklime application (NPK + Ca) increased soil pH and bacterial diversity more rapidly, whereas short-term swine manure application (NPK + M) improved soil nutrient concentration more effectively. Alteration of environmental conditions caused significant changes of bacterial community: oligotrophic groups were in greater relative abundances with quicklime treatment, whereas copiotrophic groups were in greater relative abundances with swine manure treatment. This study provides insights into the two major remediation approaches for an acidic red soil; these insights are important for soil remediating and improving fertility. Taken together, we recommended short-term quicklime application to increase the soil pH quickly and long-term swine manure fertilization to improve soil fertility.
