The enhancement of soil erosion resistance via and water conservation practices is a necessary venture in the modern agricultural industry. Soil infiltration performance, as indicator resistance, closely related to aggregates. However, relationship between C/N ratio aggregates overall performance under tillage unclear. Experiments were conducted 2022 2023 observe carbon nitrogen distribution patterns sloping cultivated land different practices. In this study, ridge pitting field + subsoiling (RF-S) contour (TP-S) have been used plot experiment, with down-slope cultivation (CK) control. results showed that stability aggregates, organic total contents particle-sizes, greatly increased RF-S TP-S treatments (up-slope, mid-slope, down-slope). Compared CK, significantly improved at slope positions (on, in, slope) particle sizes >2 mm 2–0.25 mm. more effectively reduced deposition macroaggregates down can comprehensively improve performance. mean weight diameter (MWD) geometric (GMD) reflect also indicate structure. MWD by 6% 17.7%, GMD 9.7% 27.2%, average rate 41.8% 78.3%, initial 19.1% 46.6%, stable 109.2% 165.9%. positively correlated negatively <0.25 study show reasonable measures are helpful improving anti-erosion ability illustrate influence mechanism on

Abstract The upstream of the Cisadane Watershed is included in Mount Halimun Salak National Park area as water catchment area. Water resource conservation important because land use change. Rainfall analysis was carried out to determine rain intensity amount. Then, infiltration observations were also Ecosystem Restoration (ER) areas. ER an rehabilitation zone that requires improvement, especially biophysical improvement. Several areas are Cibunian Village and Purwabakti Village. determined rates Field surveys data collection on sample measurements. Sample points selected using Stratified Random Sampling. results show average rainfall study around 3950 mm/year. ability relatively slow. However, there still rapid at several points. Due limited absorption capacity, soil characteristics with clay texture influence slow conditions. Even though high, surface runoff quickly formed. watershed should be stored reserve supply, during dry season. In detail, storage can pit, artificial tanks, reservoirs, or ponds. availability resources challenges uses Watershed. This research essential initial find more about hydrological system demand level.
