Abstract
ABSTRACT Agricultural management significantly influences soil physical properties and soil erosion. However, there are few studies investigating the long-term effects of agricultural management on soil erosion and physical properties. Here, we assessed the impacts of 20-year agricultural land uses under different management practices on soil physical properties and interrill erosion. This study was conducted on an experimental farm of the Embrapa Western Agriculture, Brazil, and the treatments consisted of soybean cropping under conventional tillage (CT) and no-tillage (NT), crop-livestock integration [...]

Erosion is a surface process mainly influenced by soil physical conditions and is one of the processes of soil degradation accelerated by anthropic activity (Murphy and Fogarty, 2019)
This study was conducted on an experimental farm of the Embrapa Western Agriculture, Brazil, and the treatments consisted of soybean cropping under conventional tillage (CT) and no-tillage (NT), crop-livestock integration during the cropping phase (CL-C) and the livestock phase (CL-L), and Brachiaria decumbens pasture under rotational grazing (PP)
We investigated the impacts of long-term agricultural production under different management systems on soil physical properties and soil erosion
Summary
Erosion is a surface process mainly influenced by soil physical conditions and is one of the processes of soil degradation accelerated by anthropic activity (Murphy and Fogarty, 2019). Production systems have been improved in recent decades so that conventional methods have lost ground to modern production and conservation systems such as no-till, intercropping, crop-livestock integration, crop-livestock-forest integration, and livestock-forestry integration These systems involve diversification of agricultural production and crop rotation, leading to better water use conditions, increasing agricultural production, and improving soil quality (Almeida et al, 2018; Sone et al, 2019). Some studies have investigated the effects of different agricultural land uses and integration systems on soil physical and chemical properties (Salton et al, 2014; Cade-Menun et al, 2017; Zajícová and Chuman, 2019) These studies found that the use of the no-till and crop-livestock system can improve soil physical properties and, control soil erosion by water in the short, medium, and long term. The lack of studies on agricultural land use impacts on soil properties and productivity has discouraged some farmers (Jose, 2009), and it undermines the advancement and application of innovative agricultural strategies that maintain soil health while increasing productivity
