Geotechnology applied to estimate soil loss by water erosion
(2015-01-01)
Water erosion is a major environmental problem that may compromise agricultural areas and the volume of water in a watershed. This paper presents the estimated soil loss in a watershed using Equation Revised Universal Soil ...
ASSESSMENT OF SOIL LOSS POTENTIAL THROUGH THE GEOGRAPHICAL INFORMATION SYSTEM (GIS) FOR THE PRIORIZATION OF RURAL ROADS IN THE MUNICIPALITY OF OURO VERDE / SP
(Univ Estadual Paulista Julio Mesquita Filho, 2019-05-01)
This work aimed to identify all the variables of soil loss potential risk condition in the municipality of Ouro Verde / SP. Therefore, along with identifying unsafe road sections to make the necessary adjustments, taking ...
Predicting soil erosion and assessing quality indicators in two Brazilian watersheds: subsidy for territorial planning
(2021-01-01)
Soil erosion might be induced by human pressure and result in irreversible environmental impacts. In the municipality of Itapevi (SP, Brazil), where demographic saturation has driven the population to the outskirts of the ...
Effects of soil texture and rates of K input on potassium balance in tropical soil
(Wiley-Blackwell, 2017-09-01)
The efficiency of potassium (K) fertilizer use is important in sustainable agriculture and is affected by losses related to soil texture. However, there is no information on how much K is lost by leaching in tropical soil. ...
Variabilidade espacial de perdas de solo, do potencial natural e risco de erosão em áreas intensamente cultivadas
(2006-04-01)
The objective of this work was to identify the spatial variability of the natural erosion potential, soil loss and erosion risk in two intensely cultivated areas, in order to assess the erosion occurrence patterns. The ...

Agricultural expansion in the Brazilian Cerrado: Increased soil and nutrient losses and decreased agricultural productivity
(2019-01-01)
While food and nutrition security are issues that national and international organizations are tackling, one of the central problems often overlooked is the essential role of soils in providing nutritious food. Soils are ...
Análise multivariada na determinação do risco de erosão em solos sob irrigação
(2010-01-01)
The objective of this work was to verify the application of cluster analysis to evaluate soil erosion risk for different soil classes, soil slopes and soil managements. The study was conducted in a 33 ha section of a large ...
