In order to explore the relationship between soil-water and fertilization under different land use types in karst rocky desertification areas, we selected cultivated land, Zanthoxylum forest, dragon fruit plantation, and loquat forest soils in the Huajiang Hot Valley area of Guizhou Province as experimental materials. We measured the soil moisture content, bulk density, maximum water holding capacity, capillary water holding capacity, capillary porosity, total porosity, and soil carbon, nitrogen, and phosphorus in these four types of sites. The results showed that the soil hydrological properties in the dragon fruit plantation were significantly lower than those in the cultivated land, Zanthoxylum forest, and loquat forest (p<0.05), but the bulk density was significantly higher, indicating poorer soil structure. Cultivated land exhibited the best soil properties among the studied land use types. The cultivated land had the highest soil organic carbon (SOC) and total phosphorus (TP) content, while the loquat forest had the highest total nitrogen (TN) content. Nitrogen deficiency was the primary limiting factor for soil in the cultivated land, while phosphorus deficiency was the primary limiting factor for the other three land use types.
