Author(s): MORAES, M. T. de; DEBIASI, H.; CARLESSO, R.; FRANCHINI, J. C.; SILVA, V. R. da 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... ... |
Author(s): OLIVEIRA, R. L. L. de; VASCONCELOS, S. S.; TEIXEIRA, W. G.; KATO, O. R.; CASTELLANI 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... ... |
Author(s): SOUZA, W. J. O. de; ROZANE, D. E.; SOUZA, H. A. de; NATALE, W.; SANTOS, P. A. F. dos 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... ... |
Author(s): MORAES, M. T. de; DEBIASI, H.; FRANCHINI, J. C.; SILVA, V. R. da 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... ... |
Author(s): RESENDE, R. S.; CINTRA, F. L. D.; PACHECO, E. P.; AMORIM, J. R. A. de; BRANT, R. da S.; SILVA, S. M. da 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... ... |
Author(s): SOUSA, A. D. de; PEDROSA, E. M. R.; ULISSES, C.; CASTRO, J. M. da C. e; RIBEIRO, J. M. 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... ... |
Author(s): NUNES, A. C. P.; RESENDE, M. D. V. de; SANTOS, G. A. dos; ALVES, R. S. 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... ... |
Author(s): CANEPPELE, B. F.; VALANI, G. P.; OLIVEIRA, P. P. A.; PEZZOPANE, J. R. M.; BERNARDI, A. C. de C.; COOPER, M. 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... ... |
Author(s): VASQUES, G. de M.; RODRIGUES, H. M.; HUBER, E.; TAVARES, S. R. de L.; MARQUES, F. A.; SILVA, M. S. L. da The objectives are to use ground penetrating radar (GPR) to: (a) find a suitable length and location for a future underground dam; and (b) model the shape and estimate the volume of its water reservoi... ... |
Author(s): NASCIMENTO, C. W. R. do; CEDDIA, M. B.; VASQUES, G. M.; RODRIGUES, H. M.; MARTINS, S. S.; OLIVEIRA, R. P. de; TAVARES, S. R. de L. The Ground Penetrating Radar (GPR) has potential to characterize soils both vertically and horizontally. The effectiveness of using GPR relies on the interpretation of soil targets in the radargrams.... ... |
