1. Crescimento e teor de cromo em mamoneira cultivada em solo receptor de resíduos de curtume e carboníferos
RESUMO A produção de resíduos tem aumentado em proporção direta com a industrialização dos países. Sendo assim, a disposição adequada desses resíduos é uma questão largamente discutida entre os órgãos ambientais. Por isso, o objetivo deste trabalho foi estudar o efeito residual de adições sucessivas de resíduos de curtume e da mineração d

2. Nitrogen supply to arugula from pig slurry composts in contrasting soils
RESUMO O estudo foi desenvolvido para avaliar o fornecimento de nitrogênio (N) à rúcula através de compostos obtidos por compostagem automatizada de dejetos líquidos de suínos (DLS). Durante a compostagem, xisto retortado (XR) e dicianodiamida (DCD) foram adicionados aos DLS para mitigar as perdas gasosas de N. O estudo foi realizado em casa de vegeta�

3. Inoculation with Azospirillum brasilense on corn yield and yield components in an integrated crop-livestock system
ABSTRACT. Inoculation of corn with diazotrophic bacteria reduces the need for nitrogen fertilization and mitigates environmental contamination risks due to the bacteria’s biological nitrogen-fixation capacity. The aim of the present study was to evaluate the effect of corn seed inoculation with Azospirillum brasilense under different nitrogen levels and p

4. Efeito de coberturas vegetais e doses de nitrogênio em cobertura no trigo irrigado por aspersão em cerrado de baixa altitude
ABSTRACT Wheat production in the Brazilian cerrado faces major challenges, especially for not being a traditionally wheat region and the occurrence of hot and dry winters. The objective of this study was to evaluate the residual effect of the previous crops corn and Urochloa ruziziensis (R. Germ & Evrard), in single cropping and intercropping, with and witho

5. Residual recovery and yield performance of nitrogen fertilizer applied at sugarcane planting
ABSTRACTThe low effectiveness of nitrogen fertilizer (N) is a substantial concern that threatens global sugarcane production. The aim of the research reported in this paper was to assess the residual effect of N-fertilizer applied at sugarcane planting over four crop seasons in relation to sugarcane crop yield. Toward this end three field experiments were es

6. Adubação nitrogenada e inoculação com azospirillum brasilense em híbridos de milho / Nitrogen application and Azospirillum brasilense inoculation on maize hybrids
Maize is one of the worlds most important cultivated cereals; however, it presents great challenges for correct fertilization management. Its high nitrogen demand has been the major cause of excessive applications of synthetic nitrogen fertilizers in the crop. As a result, both environmental and economical problems have increased. Therefore, alternative meth

7. Validation of models for predicting milk urea nitrogen concentrations, estimating dry matter intake by the NRC (2001)
The objective of this study was to validate three different models for predicting milk urea nitrogen using field conditions, attempting to evaluate the nutritional adequacy diets for dairy cows and prediction of nitrogen excreted to the environment. Observations (4,749) from 855 cows were used. Milk yield, body weight (BW), days in milk and parity were recor

8. Forage yield and quality on soil subjected to phosphorus rates in subtropical grassland of Brazil
Phosphorous application effects were evaluated on ryegrass dry matter (DM) accumulation, root development and plant tissue concentration of phosphorus, nitrogen and carbon aiming to determinate the nutritional status of the pasture, as well as to verify the possibility to establish a phosphorus dilution curve for this pasture. Also, the development of phosph

9. Estimativa da excreção urinária de derivados de purinas a partir do consumo de NDT e determinação da contribuição endógena em bovinos de corte / Estimation of urinary excretion of purines derivatives from TDN intake and determination of the endogenous contribution in beef cattle
Two experiments were conducted with eight Nelore heifers (BW 267 17 kg ) to assess the excretion of purine derivatives (PD) from intake of TND, the intake and digestibilities of nutrients and the endogenous fraction of PD and nitrogen losses using the technique of fasting. In Exp.I the animal were fed a diet based on corn silage and concentrate in the propor

10. Residual effects of successive exposure of soybean Bradyrhizobium strains to aluminium on solid defined medium.
The aim of these studies was to investigate whether residual toxic effects of exposing soybean root nodule bacteria to Al in a solid defined media (SDM) alter tolerance to Al, survival, sensitivity to antibiotics, N2 fixation effectiveness and genetic diversity of Bradyrhizobium strains. After being exposed four times to Al, strains showed variation in Al to

11. Nitrogen fixation by groundnut and velvet bean and residual benefit to a subsequent maize crop.
Chemical fertilisers are rarely avaiable to poor farmers, for whom the nitrogen (N) is often the most limiting element for cereal grain production. The objective of this study was to quantify the contribution of biological nitrogen fixation (BNF) to groundnut (Arachis hypogaea) and velvet bean (Mucuna pruriens) crops using the 15N natural abundance (d15N) te

12. Uso de biossólido em plantios florestais.
ABSTRACT: With the increase of the population density in the cities, a great amount of residual waters passed to be generated. The usual practical ones of disposal of the sewage sludge, as the "sanitary and controlled embankment" or the "oustings the opened sky", are alternative of cost to each day more raised or have potential to produce impacts ambient und
