Quantifying soil movement by forest vehicles with corpuscular metal tracers
(2018-09-01)
Bulk soil movement caused by human impact is hard to quantify. In forestry the bulk soil displacement by passage with heavy machinery is virtually unknown. We present a new method to measure such soil movement with hollow ...
Soil moisture retention and mass movement of volcanic soils from the “Sabinas” sector in Caldas, Colombia
(Universidad Nacional de Colombia - Sede Palmira, 2017-10-01)
The mass movement of soils, are soil, rocks displacements or both, caused by soil water excesses in terrains due to gravity effects and other factors. The aim of this research was to quantify the moisture retention capacity ...
The assessment of soil chemical, physical, and structural properties as landslide predisposing factors in the Serra do Mar mountain range (Caraguatatuba, Brazil)
(2020-09-01)
Landslides have environmental, social, and economic impact in the Brazilian Atlantic coast (Serra do Mar). In addition to meteorological, geological, and geomorphological settings, mineralogical and pore space heterogeneities ...

Movimento de Água e porosidade dos solos de uma sub-bacia hidrográfica no noroeste do estado de São Paulo
(2015-01-01)
Lack of environmental planning and inadequate occupation of soils in watersheds have caused their degradation. This study was conducted in the Jardim Novo Horizonte subwatershed in Ilha Solteira city, northwestern São Paulo ...
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. ...
