Modeling the impacts of no-till practice on soil erosion and sediment yield with RUSLE, SEDD, and ArcView GIS

Carbon management in dryland agricultural systems. A review

“…According to data from the Chinese national projects regarding conservation tillage, the last authors reported a 60 to 79 % decrease in soil erosion when using no-tillage. Similarly, in a modeling study, Fu et al (2006) reported a decrease of soil erosion from 17.7 to 3.9 t ha −1 year −1 when adopting no-tillage, due to mitigation of rill generation. Different tillage experiments have been carried out by the International Center for Agricultural Research in the Dry Areas (ICARDA) in the Central Asia region.…”

Spatial Estimation of Soil Erosion Risk Using RUSLE Approach, RS, and GIS Techniques: A Case Study of Kufranja Watershed, Northern Jordan

“…Information on factors leading to soil erosion can be utilized as a guide for formulating appropriate soil conservation and land management plans. The Revised Universal Soil Loss Equation (RUSLE) is frequently used to estimate the magnitude of soil erosion loss from watershed areas, the spatial distribution of soil erosion severity, and delimiting sites vulnerable to soil erosion for both agricultural and forested watersheds [30,[42][43][44][45][46][47][48]. Finally, the RUSLE model has several advantages: 1) it is easy to implement and understand from a functional perspective [32], 2) is compatible with the Geographic Information System (GIS), and 3) the data requirements to implement the model are not too complex or unattainable especially in a developing country [49].…”

“…The K factor is influenced by intrinsic soil properties related to soil profile parameters such as: percent silt (0.002 -0.1 mm), percent sand (0.1 -2 mm), percent organic matter, soil structure and permeability [43]. Soil types in the study area were identified from the National Soil Map and Land Use Project [50], and the associated reports.…”

A review of phosphorus and sediment release from Irish tillage soils, the methods used to quantify losses and the current state of mitigation practice

“…The SDR is the ratio of sediment reaching a continuous stream system to the total amount of sediment eroded by sheet and channel erosion. The magnitude of the SDR for a particular catchment will be infl uenced by a wide range of geomorphological, hydrological, environmental and catchment factors (Fu et al 2006).…”
