Nitrogen and carbon isotope composition of organic Fertilizers. Author(s): INACIO, C. de T.; CABALLERO, S. S. U.; CHALK, P. M. Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be... ... Repository: BDPA Publication year: 2013
The isotopic composition (d15N, d13C) of agricultural wastes and derived composts. Author(s): INACIO, C. de T.; MAGALHÃES, A. M. T.; SOUSA, P. O.; CHALK, M. The aim of this study was to measure variations in the isotopic composition (d13C and d15N) during the composting of different agricultural wastes using bench-scale bioreactors. Four different feedsto... ... Repository: BDPA Publication year: 2013
Fiber fractions, multielemental and isotopic composition of a tropical C4 grass grown under elevated atmospheric carbon dioxide. Author(s): ABDALLA FILHO, A. L.; COSTA JUNIOR, G. T.; LIMA, P. de M. T.; SOLTANGHEISI, A.; ABDALLA, A. L.; GHINI, R.; PICCOLO, M. de C. Abstract: Brazil has the largest commercial herd of ruminants with approximately 211 million head, representing 15% of world?s beef production, in an area of 170 million hectares of grasslands, mostly... ...

Water relations and carbon isotope composition in young plants of two provenances of Jatropha curcas L. subjected to water deficit. Author(s): GOMES, F. P.; GOMES, L. M. C.; LAVIOLA, B. G.; GRIFFITHS, H. Repository: BDPA Publication year: 2016
Bothrops atrox in captivity, change isotopic composition in tissues collected from different environments of the eastern Amazon. Author(s): MARTINEZ, M. G.; CHALKIDIS, H. de M.; MOURA, A. M.; OLIVEIRA JUNIOR, R. C. de; CAMARGO, P. B. The Bothrops Atrox is little studied because it is sympatric to Amazonian animals. Very little is known about the ecology and natural history of this species. It has a generalist diet and the distribu... ... Repository: BDPA Publication year: 2014
Origin of organic matter and quantity of transported material from Jaguari river, SP and MG, Brazil. Author(s): CAMARGO, P. B. de; COSTA, C. F. G.; FIGUEIREDO, R. de O.; PICCOLO, M. C.; REIS, L. C.; MAJER, P. E. T. The objective was to investigate the origin of the organic matter of the sediment and the particulate material in the Jaguari River, under the influence of different land uses. The basin, a few decade... ... Repository: BDPA Publication year: 2017
Different tools to trace geographic origin and seasonality of croaker (Micropogonias furnieri). Author(s): CHAGURI, M. P.; MAULVAULT, A. L.; NUNES, M. L.; SANTIAGO, D. A.; DENADAI, J. C.; FOGACA, F. H.; SANT'ANA, L. S.; DUCATTI, C.; BANDARRA, N.; CARVALHO, M. L.; MARQUES, A. The aim of this study was to use proximate chemical composition, macro and trace elements, fatty acid profile and stable isotopes as traceability tools to assess geographic origin and seasonality of c... ...

Spondias tuberosa trees grown in tropical, wet environments are more susceptible to drought than those grown in arid environments. Author(s): ANTUNES, W. C.; MENDES, K. R.; CHAVES, A. R. de M.; OMETTO, J. P.; JARMA-OROZCO, A.; POMPELLI, M. F. In this study, we investigated the different responses of Spondias tuberosa (umbu) trees, which grow in two different ecological life zones in northeast Brazil: tropical wet and tropical arid ecosyste... ...

Organic matter in areas under secondary forests and pasture. Author(s): MENEZES, C. E. G.; GUARESCHI, R. F.; PEREIRA, M. G.; ANJOS, L. H. C.; CORREIA, M. E. F.; BALIEIRO, F. de C.; PICCOLO, M. de C. The objective of this study was to evaluate the soil carbon stock (Stock C) and bulk density, the chemical and granulometric fractions of the organic matter and the isotopic signal of the soil δ1... ... Repository: BDPA Publication year: 2017
Carbon isotope fractionation for cotton genotype selection. Author(s): BRITO, G. G. de; SUASSUNA, N. D.; DIOLA, V.; SOFIATTI, V.; DUCATTI, C.; SILVA, E. T. da; MORELLO, C. de L. Repository: BDPA Publication year: 2014
