Abstract:Fertilisation is one of important factor impacting soil water content in agroecosystem. There is a poor understanding of how different fertilisation practices affect soil water content in a Mollisol in China. A long-term fertilisation field experiment including three treatments: no fertiliser (NF), chemical fertiliser (NP) and chemical fertiliser plus pig manure, was conducted in order to investigate the effect of different fertilisation practices on soil water content in a Mollisol. NPM had lower soil water content than NP with 2.07% decrease and CK with 2.78% decrease in view of mean soil water content in 0-170 cm soil layer. During growing season, the largest difference of soil moisture among CK, NP and NPM was observed in early August due to evapotranspiration with the increasing order of NPM, NP and CK. Different fertilisation practices have significant impact on soil water content within 0-50 cm; the difference was decreased with soil depth increasing. Therefore, different fertilisation practices impacted the soil water content in a Mollison in China as deep as 50 cm.
