Nutritional evaluation of Brachiaria brizantha cv. Marandu cultivated in soils developed from basalt and sandstone in the state of Parana

Autor: Guerra, G. L., Becquer, Thierry, Vendrame, P. R. S., Galbeiro, S., Brito, O. R., da Silva, L. D. F., Felix, J. C., Lopes, M. R., Henz, E. L., Mizubuti, I. Y.

Determining the nutritional composition of a pasture is necessary to evaluate its quality, aiming to meet the requirements of feeding animals and guarantee good performance. The quality of the forage biomass produced depends directly on the fertility

Mineralogical analysis of ferralitic soils in Madagascar using NIR spectroscopy

Autor: Ramaroson, V. H., Becquer, Thierry, Sa, S. O., Razafimahatratra, H., Delariviere, J. L., Blavet, Didier, Vendrame, P. R. S., Rabeharisoa, L., Rakotondrazafy, A. F. M.

The applicability of near-infrared reflectance spectroscopy (NIRS) as tool for estimating mineral soil constituents was assessed over a wide range of highly weathered soils in Madagascar. The predictions were based on two types of methods, chemometri

Phosphorus bioavailability in soybean grown after pasture under different fertility regimes

Autor: Eberhardt, D. N., Becquer, Thierry, Marchao, R. L., Vendrame, P. R. S., Vilela, L., Corazza, E. J., Guimaraes, M. D.

The aim of this study was to evaluate the residual effect of phosphorus (P) fertilizer applied to an Urochloa decumbens cv. Basilisk pasture on the P bioavailability to the following soybean crop. Low-productivity pasture, planted on an Oxisol in an

The potential of NIR spectroscopy to predict soil texture and mineralogy in Cerrado Latosols

Autor: Vendrame, P. R. S., Marchao, R. L., Brunet, Didier, Becquer, Thierry

Near-infrared reflectance spectroscopy (NIRS) has been accepted as a fast method to evaluate various soil constituents. However, very few studies have used NIRS as a predictor of the textural and mineralogical content of tropical soils. The objective

Fertility and acidity status of latossolos (oxisols) under pasture in the Brazilian Cerrado

Autor: Vendrame, P. R. S., Brito, O. R., Guimarães, M. F., Martins, E. S., Thierry Becquer

Publikováno v: Scopus-Elsevier

The Cerrado region, with over 50 million hectares of cultivated pasture, provides 55% of Brazilian beef production. Previous investigations have shown that about 70-80% of this pasture is affected by some kind of degradation, leading to low productiv

Influência da granulometria e da mineralogia sobre a retenção do fósforo em latossolos sob pastagens no cerrado = Influence of soil texture and mineralogy on phosphorus retention in Cerrado Oxisols under pasture

Autor: Eberhardt, D. N., Vendrame, P. R. S., Becquer, Thierry, Guimaraes, M. D.

Pastures cover nearly 50 million hectares in the Cerrado region. The Oxisols, which cover approximately half this area, are highly weathered soils composed mainly of kaolinite, iron and aluminum oxides. Iron and aluminum oxides have a great influence

Disponibilidade de cobre, ferro, manganês e zinco em solos sob pastagens na Região do Cerrado = Availability of copper, iron, manganese and zinc in soils under pastures in the Brazilian Cerrado

Autor: Vendrame, P. R. S., Brito, O. R., Quantin, C., Becquer, Thierry

The objective of this work was to describe the total and available Cu, Fe, Mn and Zn contents, and their relation with the oxisols acidity, fertility, texture and mineralogy under Cerrado pastures. The soil samples were taken from three regions: alon
