1. Corrective phosphate application as a practice for reducing oxidative stress and increasing productivity in sugarcane
RESUMO A fosfatagem aumenta os teores de fósforo (P) na camada superficial do solo, estimula o crescimento das raízes das plantas e aumenta o volume de solo explorado para absorção de água e nutrientes, o que pode reduzir o estresse oxidativo abiótico na cana-de-açúcar. O objetivo deste trabalho foi avaliar a produtividade e a resposta do sistema enz

2. Acid Ammonium Citrate as P Extractor for Fertilizers of Varying Solubility
ABSTRACT: There are several globally accepted methods to chemically characterize P-fertilizers, but not all are suitable to predict the agronomic efficiency of the P sources in terms of plant nutrition. Our aim was to investigate the performance of P extractors for fertilizers, investigating the consistency of different methods for P sources of varying prope

3. Characterization of Single Superphosphate Powders – a study of Milling Effects on Solubilization Kinetics
Conventional single superphosphate (SSP) is known as one of the most important and common sources of phosphorus in agriculture. Despite SSP has been widely produced as a fertilizer, a few studies have been done to describe the fundamental aspects of this P-fertilizer, i.e., phase composition, thermal degradation behavior, and solubility kinetics. Therefore,

4. Capim-piatã adubado com fontes de fósforo de diferente solubilidade em água
The development of piatã grass fertilized with phosphorus sources with different solubilities in water was evaluated. The experiment was developed in the unit of Aquidauana of UEMS, MS, from February to August, 2012. Four treatments were evaluated: control (without phosphorus fertilization), slow solubility, fast solubility (readily available), and mixed so

5. Effect of light sources and curing mode techniques on sorption, solubility and biaxial flexural strength of a composite resin
Adequate polymerization plays an important role on the longevity of the composite resin restorations. OBJECTIVES: The aim of this study was to evaluate the effect of light-curing units, curing mode techniques and storage media on sorption, solubility and biaxial flexural strength (BFS) of a composite resin. MATERIAL AND METHODS: Two hundred and forty specime

6. Solubilisation of inorganic phosphates by inoculant strains from tropical legumes
Microbial solubilisation of low soluble inorganic phosphates is an important process contributing for the phosphorus available to plants in tropical soils. This study evaluates the ability of inoculant strains for tropical legumes to solubilise inorganic phosphates of low solubility that are found in tropical soils. Seven strains of Leguminosae nodulating ba

7. Limestone and oyster shell for brown layers in their second egg production cycle
This study aimed at evaluating the effect of dietary calcium levels and the replacement of calcium sources with different particle size compositions on the performance and egg quality of brown layers in their second egg production cycle. A randomized block experimental design was applied with 12 treatments in a 3x4 factorial arrangement: three calcium levels

8. Eficiência agronômica de fertilizantes fosfatados em solos com diferentes capacidades de adsorção de fósforo e teores de matéria orgânica / Agronomic efficiency of phosphate fertilizers in soils with different capacity of phosphate adsorption and organic matter levels
Tropical soils highly intemperized show increased capability on phosphorus (P) adsorption. Several factors may influence P adsorption in such soils, but special attention must be paid on the organic matter level. Mechanisms involved in this process are related to the release of organic acids derived from the decomposition of the organic matter, which may eit

9. Solubilization of phosphorus by endofhytic bacteria / Solubilização de fósforo por bactérias endofíticas
Soil microorganisms directly affect fertility and plant yield. Among these, inorganic phosphate solubilizers enhance phosphorus availability, and may increase phosphorus fertilizers efficiency. This work aimed to select inorganic phosphorus solubilizing bacteria as potential plant growth promoters. On the first stage, previously obtained isolates, from leave

10. Efeito do fosfato bicálcico ou monoamônico sobre a digestibilidade ruminal do feno de coast-cross / Effects of dicalcium or monoammonium phosphate on ruminal digestibility of coast-cross hay
The effects of phosphorus from Dicalcium Phosphate (DCP) or Monoammonium Phosphate (MAP) sources were evaluated on in situ ruminal digestibility of coast-cross hay (Cynodon dactylum) and also their solubility using in vitro study. Twelve Suffolk crossbred wethers were used, fitted with ruminal cannulas. The experimental period was divided into two stages: th

11. Distribuição do fósforo no perfil do solo sob sistema plantio direto
The Cerrado, even with soils of low fertility, has been increasing in importance within the Brazilian agricultural scenario, by planning the use and management of land, with the adoption of no-tillage system (NT) and the use of correctives and fertilizers. The application of fertilizers in NT is all doneon the soil surface, which leads to the accumulation of

12. Characterization of biofilms produced from pea (Pisum sativum) starch associated with xanthan gum and glycerol / Caracterização de biofilmes obtidos a partir de amido de ervilha (Pisum sativum) associado à goma xantana e glicerol
In the past few years, the attempt to obtain degradable flexible packaging has increased considerably. In this sense, starches obtained from different botanical sources have been evaluated to produce films. Most of these films present good mechanical characteristics and provide a good barrier to oxygen. Nevertheless, some limitations have been observed in re
