Considerações teóricas sobre o cálculo da resistência mecânica do solo à penetração determinada com penetrômetros dinâmicos. ABSTRACT: The aim of this work was to describe an equations to calculate the soil mechanical impedance by dynamic penetrometers. The calculations regard two different equipments, including theoretical... ... Repository: BDPA Publication year: 2007
An agglomerated powder supplement may improve the efficiency of mineralization of grazing cattle. Losses in mineral supplementation of grazing cattle is likely to occur in unsheltered troughs, mainly throughout the rainy season both by lixiviation and hardening. The aim was to evaluate supplement... ... Repository: BDPA Publication year: 2018
Avaliação da resistência à penetração em diferentes sistemas em lote de reforma agrária no município de Itapeva, SP. O sistema vivo, complexo e dinâmico do solo tem sido, no ultimo século, considerado apenas um suporte inerte para a obtenção de lucro pela agricultura convencional e os passivos de degradação de sua e... ...

Machine traffic and soil penetration resistance in guava tree orchards. The study was conducted in irrigated commercial orchards of ?Paluma? and ?Pedro Sato? guavas, which were mapped with a Garmin GPS unit (Cx60). Sixty five sampling points were marked on a 21 x 21 m sam... ... Repository: BDPA Publication year: 2018
Temporal variation of penetration resistance in an agroforestry system with oil palm. Soil penetration resistance penetration is property important to characterize the state of soil compaction in cultivated systems. Thus, this work aimed to evaluate the impacts of management and moistu... ... Repository: BDPA Publication year: 2021
Soil resistance to penetration in an oxisol under integrated and non-integrated grazing systems in southeast Brazil. In order to learn more about soil physical quality in integrated systems, this study proposed comparing soil penetration resistance in two different depths, 0 - 5 cm and 12.5 - 17.5 cm, in areas under... ...

Compactação do solo: consequências para o crescimento vegetal. ABSTRACT: Soil compactation is problem in modern agriculture. Over cultivation, intensive cropping and inappropriate soil management leads to soil compactation. There are important factors which direc... ... Repository: BDPA Publication year: 2005
Field proximal soil sensor fusion for improving high-resolution soil property maps. Mapping soil properties, using geostatistical methods in support of precision agriculture and related activities, requires a large number of samples. To reduce soil sampling and measurement time and c... ... Repository: BDPA Publication year: 2020
Resistência à penetração de um Latossolo Vermelho-Amarelo Distrófico sob diferentes manejos e métodos. Os sistemas de manejo têm grande influência nas propriedades físicas do solo e estão relacionados com a compactação do solo. Assim, este trabalho teve o objetivo avaliar a resistência mecânica do solo... ... Repository: BDPA Publication year: 2020
Soil penetration resistance in a rhodic eutrudox affected by machinery traffic and soil water content. ABSTRACT: Soil compaction caused by machinery traffic reduces crop yields. This study aimed to evaluate the effects of intensive traffic, and the soil water content, on the soil penetration resistance... ... Repository: BDPA Publication year: 2013
