Stock and carbon levels in the soil in the tree lines or pasture lane in integrated production system (iCLF) in the western Brazilian Amazon. Author(s): PERIN, R.; TONATO, F.; SOUSA, J. N.; MARTINS, G. C. The objective of this study was to evaluate the stock (STC) and the C content (Ccont) in the soil in the tree lines or pasture lane of an integrated system iCLF with Mahogany (Swietenia macrophylla) a... ...

Sub-surface soil organic carbon stock affected by tree lines in an oxisol under integrated crop-livestock-forestry in the Southern Amazon. Author(s): MADARI, B. E.; OLIVEIRA, J. M.; CARVALHO, M. T. de M.; WRUCK, F. J.; MACHADO, P. L. O. de A. The carbon (C) removed from the atmosphere through photosynthesis may be finally transferred into the soil. Soil organic C storage (SOC), therefore, is an important indicator of the capacity of a prod... ... Repository: BDPA Publication year: 2017
Quantification of total carbon in soil using laser-induced breakdown spectroscopy: a method to correct interference lines. Author(s): NICOLODELLI, Gustavo; MARANGONI, Bruno.

Bacterial communities in the rhizosphere of sorghum (Sorghum bicolor) lines contrasting for aluminum tolerance cultivated in unlimed and limed soil. Author(s): SILVA, L. F.; LANA, U. G. P.; OLIVEIRA-PAIVA, C. A.; SOUZA, F. A.; MARRIEL, I. E.; GOMES, E. A. Repository: BDPA Publication year: 2012
Combining ability among maize inbred lines for tolernace to low phosphorus content in the soil. Author(s): GAMA, E. E. G.; PARENTONI, S. N.; ALVES, V. M. C.; GUIMARAES, P. E. O.; PACHECO, C. A. P.; LEITE, C. E. P.; TEIXEIRA, F. F.; MAGALHAES, J. V. Repository: BDPA Publication year: 2006
Assessment of sugarcane harvesting residue effects on soil spectral behavior. Author(s): DEMATTÊ, J. A. M.; TERRA, F. da S.; OTTO, R.; TOMA, R. S.; PEREIRA, L. H.; NASCIMENTO, A. F. do; BORTOLETTO, M. A. M. When the harvesting of sugarcane involves a mechanized process, plant residues remain on the soil surface, which makes proximal and remote sensing difficult to monitor. This study aimed to evaluate, u... ... Repository: BDPA Publication year: 2016

Soil fertility evaluation is important for adopting conservation management and adequate nutrient supply. The objective of this study was to identify critical levels and soil fertility classes using t... ... Repository: BDPA Publication year: 2024
Water use efficiency: behavior of upland rice lines under water deficit. Author(s): VILLELA, G. M.; ROSÁRIO NETO, A.; BOTELHO, F. B. S.; LIMA, I. P. de; CASTRO, A. P. de; CASTRO, D. G. Upland rice (Oryza sativa) is affected by several biotic and abiotic factors that limit the yield potential of cultivars. In relation to water deficiency, the development of drought tolerant and water... ... Repository: BDPA Publication year: 2021
Soil ecotoxicology and mesofauna at the site of an attested oil spill in Ipanema National Forest. Author(s): SCORIZA, R. N.; CORREIA, M. E. F. A disused electrical substation was the site of the spill of 40,000 L of Ascarel oil. However, none of the expected principal contaminants were chemically detected above established guidelines. Since... ... Repository: BDPA Publication year: 2018
