Land use impacts soil quality in Wuling Mountain, affecting nutrient levels.
The study looked at how different types of land use affect soil properties in hilly areas. Soil samples from cropland, orchards, woodlands, unused land, and intercropping land were analyzed. Woodlands had the highest levels of organic carbon, total nitrogen, available nitrogen, and available potassium, but the lowest soil moisture. Intercropping land had the lowest levels of organic carbon and total nitrogen. Unused land had high soil moisture and bulk density, but low available phosphorus and potassium. Soil nutrients decreased with soil depth. Overall, woodland had abundant soil nutrients, while total nitrogen and organic carbon were deficient in all land uses.
