    Son La is a province in the Northwest region of Vietnam; this province has diverse terrains with elevation ranging from &#x;m to 2,&#x;m. Due to lack of cultivating lands, farmers still cultivate lands with steep slope, even above 25o. Consequently, the soil erosion has occurred hugely and the time for productive cultivation has been shortened. Therefore, it is The runoff study investigated soil P dynamics when partially P-saturated RM and WTR's were surface applied to grass plots at 2 t ha.

      Data collected from both artificially and field (naturally) weathered biochar suggest that a potentially significant pathway of biochar disappearance is through physical breakdown of the biochar structure. Via scanning electron microscopy, we characterized this physical weathering that increased the number of structural fractures and yielded higher numbers of liberated biochar :// Abstract. A rainfall simulation technique was used to evaluate the influence of slope steepness (3 and 9%), mulch rate (0, , and t/ha), and antecedent soil moisture conditions (dry and wet runs), on runoff, splash, soil loss in runoff and the primary particle composition of soil in splash and sediment from interril areas on two mined land ://

    The average soil loss estimated by TC using MMF model at catchment level was 26 t ha −1 y −1. In most parts of the catchment (>80%), the model predicted soil loss rates higher than the maximum tolerable rate (18 t ha −1 y −1) estimated for Ethiopia.

Get this from a library. A Runoff and soil-loss monitoring technique using paired plots. [William L Jackson; United States. Bureau of Land Management.;] Abstract. A low-cost runoff and sediment monitoring technique which uses rectangular plots and collection devices is described.

The technique is presently being tested near Hobu Community School, approximately 15 km NE of the Papua New Guinea University of Technology, ://   The runoff and soil loss from the treated plots were measured for seven rainfall events that produced runoff during normal rainy season of the study area i.e., December to May Results showed that inoculation of cyanobacteria significantly (p runoff by s 25, 31, 33, 46, 47, and 57% for the recorded rainfall   The plots shown in Plate 4 had only simple brick tanks into which the runoff and soil loss flowed, and they overflowed in heavy storms so that only a proportion of the soil lost was caught in the tanks, but they were very effective for demonstrating to large numbers of farmers the essential principle of reducing erosion by better   Considerations in Rangeland Watershed Monitoring Jackson 09/ BLM Technical Note A Runoff and Soil-loss Monitoring Technique Using Paired Plots Jackson 08/ BLM Technical Note Gully Erosion Harvey 03/ BLM Technical Note Hydrology and the Universal Soil Loss Equation: Application to Rangelands Hawkins 06/ BLM   A replaceable loss, for example, may be nutrients lost in eroded soil; an irreplaceable loss may be the loss in water-holding capacity resulting from decreased soil depth.

Similarly, Walker and Young () and Young () distinguished between reparable and residual loss of yields resulting from soil :// We survey soil erosion processes using an index of connectivity and a non invasive and long-term assessment in situ technique: the ISUM (Improved Stock Unearthing Method).

Sustainable land management interventions were introduced in Geda watershed in to reduce soil erosion, improve water infiltration, and increase plant-carbon inputs into the soil. This study explored the impact of the interventions on biomass production, carbon stock, and carbon sequestration.

Stratified sampling was employed in the main and the dry seasons in the treated and untreated sub Abstract. Surface runoff, or overland flow, is a fundamental process of interest in hydrology. Surface runoff generation can occur at multiple scales, ranging from small pools of excess water that propagate downhill to stream networks that drain large ://   The runoff plots (Fig.

Twelve m2 plots were constructed in an orchard in Davis, California, on bare soil. Two separate 2-event rain treatments were To determine the erosivity index, a large number of correlations between rainfall-runoff factors and soil loss often need to be compared (e.g.

[14–17, 23, 25, 26, 36–37]). For example, the EI 30 index was established as the rainfall erosivity index of the USLE by comparing correlations of more than 40 factors with soil loss [38–40].

As a The soil loss from this one event was 22 tonnes per hectare. Treatments A and B with higher cover levels had much less runoff, soil and nutrient loss. It can take thousands of years to form an inch of soil. The depth of soil lost from treatment C from this one storm event may take hundreds of years to replace, provided no further erosion :// Mean annual rainfall-induced runoff coefficient was and mean annual soil loss was Mg ha-1 y Irrigation contributed to 40% of the crop water supply, but the amount of runoff and sediment yield that it generated was :// Using simulated rainfall events and runoff-erosion plots the effects of coarse-fragment content and size on runoff, infiltration and soil loss were evaluated on an Orthic Dystric ://   Much quality data exist in the UK to describe erosion by water, but it is argued here that few datasets provide the necessary detail with which to evaluate model performance accurately, especially when the description of the spatial heterogeneity of soil loss is a ://   Herbicide use while being of a great benefit in controlling weeds in agricultural systems can also pose a threat to environmental quality due to off-target and off-site impacts.

Monitoring and mediating the negative consequences of LULCC while sustaining the production of essential resources has therefore become a major priority of. Soil erosion is defined as a displacement of solid particles originating from soil, rock, and other sediments.

Soil is a key component of the ‘Earth system’ in controlling the biological, geochemical hydrological, and erosional cycles and also providing goods, resources, and services (Keesstra et al.; Brevik et al.

).Soil is naturally removed by the action of water or wind   The data includes plot geometry, soil density, soil gradation, antecedent and post treatment soil water content, loose surface soil, hydrographs, sediment yield, and rainfall duration, intensity, and distribution.

These data were collected from dry and wet runs from 10 road sections at five different mines for a total of 24 ://  Soil Erosion and Global Change: this is COST Actionfunded by the European Union.

Main objectives are to make realistic predictions of the impacts of changes in land-use and climate on soil erosion across a range of temporal and spatial scales; to identify critical thresholds in the landscape and soil profile which lead to irreversible changes in the rate and style of soil erosion, and
