Long-Term Effect of Soil Use and Management on Organic Carbon and Aggregate Stability

Neuro Hilton Wolschick, Fabrício Tondello Barbosa, Ildegardis Bertol, Bárbara Bagio, Danieli Schneiders Kaufmann

05/Sep/2018

ABSTRACT: The conversion of native grassland into farmland causes changes in the soil. Tillage has profound effects on soil organic matter. The intensification of soil tillage decreases soil quality by reducing aggregate stability. Soil aggregate stability and soil organic matter are key indicators for soil quality and environmental sustainability in agro-ecosystems. The aim of the present study is to evaluate the total organic carbon content and the physical and chemical fractions of the organic matter in a soil under different […]

Water Erosion in Different Slope Lengths on Bare Soil

Bárbara Bagio, Ildegardis Bertol, Neuro Hilton Wolschick, Danieli Schneiders, Maria Aparecida do Nascimento dos Santos

20/Feb/2017

ABSTRACT Water erosion degrades the soil and contaminates the environment, and one influential factor on erosion is slope length. The aim of this study was to quantify losses of soil (SL) and water (WL) in a Humic Cambisol in a field experiment under natural rainfall conditions from July 4, 2014 to June 18, 2015 in individual events of 41 erosive rains in the Southern Plateau of Santa Catarina and to estimate soil losses through the USLE and RUSLE models. The […]

Nutrient and Organic Carbon Losses, Enrichment Rate, and Cost of Water Erosion

Ildegardis Bertol, Rodrigo Vieira Luciano, Camilo Bertol, Bárbara Bagio

20/Feb/2017

ABSTRACT Soil erosion from water causes loss of nutrients and organic carbon, enriches the environment outside the erosion site, and results in costs. The no-tillage system generates increased nutrient and C content in the topsoil and, although it controls erosion, it can produce a more enriched runoff than in the conventional tillage system. This study was conducted in a Humic Cambisol in natural rainfall from 1997 to 2012 to quantify the contents and total losses of nutrients and organic C […]
