Resistência do solo com cultivo de erva-mate e plantas de cobertura
(Universidade Federal de Santa Maria, 2021-08-27)
Improper management in production systems can lead to soil degradation, by erosion, loss of organic carbon and even by the compaction process, which is one of the main ways of compromising its structure. The soil susceptibility ...
Estrutura e funcionalidade do sistema poroso do solo em sistemas com uso de plantas de cobertura
(Universidade Federal de Santa Maria, 2021-08-31)
The soil structure and the porous system are essential for the soil to perform its environmental
functions. The use of cover crops can be a useful tool for improving the functionality of the
soil due to the contribution ...
Modeling sediment yield on hillslopes under no-till farming
(Universidade Federal de Santa Maria, 2021-05-31)
A geração e o desenvolvimento do escoamento superficial dependem de vários fatores que controlam a infiltração de água no solo e a propagação do escoamento superficial. A quantidade de água que não é infiltrada tem o ...
Caracterização e modelagem dos processos erosivos com interface canal-encosta em bacias de elevado gradiente topográfico: o caso da bacia experimental do rio Guarda Mor
(Universidade Federal de Santa Maria, 2022-10-27)
Water erosion is closely related to environmental preservation, sanitary quality and general infrastructure problems. The phenomenon of sediment transport in channels is extremely complex because it is a non-punctual ...
Espectroscopia Vis-NIR-SWIR combinada com machine learning para predição de cobre e zinco em solos de vinhedos no sul do Brasil
(Universidade Federal de Santa Maria, 2022-12-30)
Careful and sustainable management of vineyard soils is fundamental to the success of
vineyards. These areas have been faced with high levels of available copper (Cu) and zinc (Zn)
in the soil, as a result of the frequent ...
Espaço poroso avaliado por tomografia e propriedades hídricas e mecânicas em solos argilosos sob culturas anuais e campo natural
(Universidade Federal de Santa Maria, 2020-07-16)
The growing demand for food and energy causes an intensification in agriculture, which uses
larger machines and results in high pressures applied to the soil. As the pressures increases there
are changes in the soil ...
Qualidade e quantidade de resíduos culturais modulam a estabilização de carbono e nitrogênio no solo
(Universidade Federal de Santa Maria, 2023-03-31)
Crop residues left on the soil surface play an important role in controlling erosion,
nutrient cycling and soil organic matter (SOM) formation. The diversification of
cropping systems is a strategy that allows the input ...
Funções das áreas hidrologicamente frágeis na formação e modelagem do escoamento superficial na bacia experimental do Arroio Lajeado Ferreira, Arvorezinha - RS
(Universidade Federal de Santa Maria, 2022-10-31)
Physically based and distributed erosion models like the Limburg Soil Erosion Model (LISEM) are complex and
require high-quality information, equations aligned with the processes, and accurate spatial representation ...
Dinâmica do carbono influenciada pela qualidade de resíduos culturais, teor inicial de carbono e textura em dois solos subtropicais
(Universidade Federal de Santa Maria, 2020-02-28)
Crop residues quality and initial soil carbon (C) content influence the residue-derived C
dynamic in agricultural soils. However, there is a limited understanding about the fate of residue
C and the net C balance in the ...
Structural architecture and functioning of an alfisol after 17 years of organic fertilization in no-till cropping
(Universidade Federal de Santa Maria, 2023-06-05)
Using animal manure as fertilizer is an alternative adopted in Brazilian agricultural farms,
especially where there is integrated production of animals and crops. Nevertheless, the longterm impacts of continuous application ...
