چکیده
ABSTRACT The study aimed to identify and evaluate the spatial variability in laminar erosion areas using precision agriculture tools. Soil data from three properties western region of Paraná state, Brazil, were used: one municipality Céu Azul (area A) two Serranópolis do Iguaçu (areas B C). To discrepant (outliers), analysis dispersion quartiles was performed a box-plot graph. Data normality verified Kolmogorov-Smirnov test. A AgDataBox-Map software. parameters universal soil loss equation estimated used with map algebra produce model susceptible erosion. Area (soil estimate = 0-200 t ha-1 per year) presented greater susceptibility than C 0-150 year); however, all had low

Application of Gully and Rill Erosion Indicators for Estimating Soil Loss Using GIS Techniques
The problems of land degradation and soil loss are among the major problems of watersheds in Iran. For erosion andsediment estimation one can use statistical and empirical methods. For doing this, land unit map and the map of effectivefactors should be prepared. For erosion and sediment estimation one can use statistical and empirical methods. However,these empirical methods are usually time co...

متن کاملModeling Soil Erosion Using Rusle and Gis Tools
Soil erosion involves detachment and transport of soil particles from top soil layers, degrading soil quality and reducing the productivity of affected lands. Soil eroded from the upland catchment causes depletion of fertile agricultural land and the resulting sediment deposited at the river networks creates river morphological change and reservoir sedimentation problems. However, land managers...

متن کاملSoil macronutrient sensing for precision agriculture.
Accurate measurements of soil macronutrients (i.e., nitrogen, phosphorus, and potassium) are needed for efficient agricultural production, including site-specific crop management (SSCM), where fertilizer nutrient application rates are adjusted spatially based on local requirements. Rapid, non-destructive quantification of soil properties, including nutrient levels, has been possible with optica...
