- This study examines how soil aggregate stability and organic carbon (SOC) vary across different grassland types in temperate deserts, focusing on the Longzhong Loess Plateau, using analytical methods like wet sieving and correlation analysis.
- Findings indicate that certain grassland types (specifically one type) have significantly higher levels of larger soil aggregates and SOC compared to others, particularly in the upper soil layers (0-10 cm and 10-20 cm).
- As soil depth increases, the largest aggregate and SOC contents were observed at the 10-20 cm layer, while the aggregate content of a specific grassland type was primarily composed of medium-sized aggregates (0.25-2 mm).
- The study examined how climate factors like average precipitation and temperature affect soil carbon, nitrogen, and phosphorus across different depths in Longzhong's temperate steppe.
- Findings revealed that as soil depth increases, the contents of carbon and nitrogen, as well as their ratios to phosphorus, decrease, while the carbon to nitrogen ratio increases, with phosphorus levels remaining stable.
- The research concluded that while precipitation primarily influences soil nutrient content, the impact of temperature varies depending on soil depth, indicating that these climate factors interact differently with soil nutrients at different layers.
