Critical limits of soil penetration resistance in a rhodic Eutrudox. ABSTRACT: Soil penetration resistance is an important indicator of soil physical quality and the critical limit of 2 MPa has been widely used to characterize the soil physical quality, in both no-till... ...

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... ... Repositório: BDPA Ano de publicação: 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... ... Repositório: BDPA Ano de publicação: 2021
Evaluation of different selection indices combining Pilodyn penetration and growth performance in Eucalyptus clones. The present study aimed to evaluate the selection indices efficiency for Pilodyn penetration combined with growth traits in Eucalyptus clones. It was carried out experiments in a randomized block desi... ... Repositório: BDPA Ano de publicação: 2017
Correction of resistance to penetration by pedofunctions and a reference soil water content. ABSTRACT: The soil penetration resistance is an important indicator of soil compaction and is strongly influenced by soil water content. The objective of this study was to develop mathematical models... ... Repositório: BDPA Ano de publicação: 2012
Soil penetration resistance and Sugarcane rooting under subsuperficial drip irrigation levels. Knowledge of the soil water regime in a dynamic equilibrium condition (steady state) of the emitter?soil?plant system is essential to evaluate the adopted irrigation management, aiming to maximize the... ...

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... ... Repositório: BDPA Ano de publicação: 2013
Penetration, development, and reproduction of Meloidogyne enterolobii on Psidium species and induced cellular responses in the roots. Meloidogyne enterolobii has severely compromised the main guava producing regions in Brazil, thereby stimulating the development of resistant varieties for efficient management of this nematode. This... ... Repositório: BDPA Ano de publicação: 2017
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... ...

Soil mechanical resistance to penetration (SMRP) in an Oxisol under different integrated crop/livestock systems (CLS). The high values of SMRP indicate reduction of soil water infiltration and high levels of soil erosion. Integrated CLS include forest and pastures. The SMRP of soils managed with CLS can be affected by... ... Repositório: BDPA Ano de publicação: 2015
