Depth-stratified soil sampling for assessing nematode communities. Author(s): ARIEIRA, G. de O.; SANTIAGO, D. C.; FRANCHINI, J. C.; GUIMARAES, M. de F. Repository: BDPA Publication year: 2016
Guided soil sampling using soil management zones and proximal soil sensors to improve cost-benefit ratio of fertilizer recommendations. Author(s): VASQUES, G. M.; RODRIGUES, H.; OLIVEIRA, R. P. de; CEDDIA, M. B.; HERNANI, L. C.; TAVARES, S. R. de L. The objective was to integrate soil data from two proximal soil sensors to improve the delineation of homogeneous soil regions using a k-means clustering algorithm defining three distinct management z... ...

The match between microbial community structure and soil properties is modulated by land use types and sample origin within an integrated agroecosystem. Author(s): LISBOA, F. J. G.; CHAER, G. M.; FERNANDES, M. F.; BERBARA, R. L. L.; MADARI, B. E. It is of global concern to adopt measures to mitigate land degradation caused by agricultural production systems. One of the strategies proposed is to replace degraded pastures with agrosilvopastoral... ... Repository: BDPA Publication year: 2014
An optimized sample for assessing soil property variations across the field and within management zones efficiently. Author(s): VASQUES, G. de M.; RODRIGUES, H. M.; TAVARES, S. R. de L.; HERNANI, L. C.; OLIVEIRA, R. P. de An optimized sampling design to assess soil property variation across the field and within management zones is proposed and validated in a 72-ha crop field in southeastern Brazil. An optimized sample... ... Repository: BDPA Publication year: 2022
Enzyme activities in a sandy soil of Western Bahia under cotton production systems: short-term effects, temporal variability, and the FERTBIO sample concept. Author(s): LOPES, A. A. DE C.; BOGIANI, J. C.; FIGUEIREDO, C. C. DE; REIS JUNIOR, F. B. dos; SOUSA, D. M. G. de; MALAQUIAS, J. V.; MENDES, I. de C. Enzyme activities (EAs) and the FERTBIO sample concept have been increasingly adopted as a novel approach to estimate the soil quality in Brazil. However, the performance of this strategy in sandy soi... ... Repository: BDPA Publication year: 2021
Imazaquin sorption in surface and subsurface soil samples. Author(s): OLIVEIRA, M. F. de; PRATES, H. T.; SANTANA, D. P.; OLIVEIRA JÚNIOR, R. S. de The objective of this work was to study the sorption and desorption of imazaquin, in surface and subsurface soil samples from Brazil. Sorption and desorption steps were carried out using batch equilib... ... Repository: BDPA Publication year: 2006
Sample design effects on soil unit prediction with machine: randomness, uncertainty, and majority map. Author(s): CARVALHO JUNIOR, W. de; PEREIRA, N. R.; FERNANDES FILHO, E. I.; CALDERANO FILHO, B.; PINHEIRO, H. S. K.; CHAGAS, C. da S.; BHERING, S. B.; PEREIRA, V. R.; LAWALL, S. Notwithstanding the importance of soil surveys, advances in digital soil mapping have mainly focused on mapping soil attributes or properties rather than developing digital maps of soil units or soil... ...
