Effect of Long-term Fertilization on Soil Plough Layer Carbon Storage in a Reddish Paddy Soil
长期施肥对红壤稻田耕层土壤碳储量的影响

With a reddish paddy soil as test materials,soil profile nitrogen storage in long-term different fertilization system(1990-2006) have been investigated.The result indicated that recycling of organic matter significantly increased the soil profile C storage(ranged from 57.7 to 66.2 t/hm~2),and it was increased by 18.7-27.2 t/hm~2 compared with the soil profile C storage of 1990.But it was increased by 5.4 t/hm~2 with only application of chemical fertilizers.Saturated carbon storage of paddy soils was 84.0 t/...
