The objective of this study was to investigate the influence of application of biochar and biochar-based compound fertilizer on soil water retention under test of improving brown soil for the sixth year in a row, so as to provide a theoretical reference for the use of biochar-based fertilizers in agriculture. A micro-plot (2 m2) field experiment was conducted from 2009 to 2014 with peanut as tested crop. Four treatments were designed: corn straw returning in combination with NPK (CS), pig manure in combination with NPK (PMC), biochar from corncob in combination with NPK (BIO), and biochar-based compound fertilizer (BF). Surface soil moisture content, cumulative evaporation of water, soil physical and chemical properties of peanut field were determined using their relevant methods before sawing and at different developmental stages of peanut in 2014. The results show that when the water is adequate for the treatments of soil, soil moisture content of BIO and BF were close to PMC and higher than CS; when the water moisture is low, BIO and BF were lower than PMC and CS. Compared with CS and PMC, BIO can improve the soil water quantity but lower soil water retention capacity, BF decreases the soil water quantity and water retention capacity.
