1. Bone meal as a source of phosphorus for forage sugarcane1
RESUMO Adubos fosfatados de origem orgânica podem apresentar-se como alternativas viáveis para a substituição de adubos minerais na nutrição de culturas como a cana-de-açúcar forrageira. Objetivou-se investigar os efeitos da adubação fosfatada com farinha de ossos e superfosfato simples sobre a concentração de fósforo (P) no tecido vegetal, sól

2. Phosphorus sources associated with organic compound in broccoli production and soil chemical attributes
RESUMO O fósforo é um recurso natural finito e o uso de fontes fosfatadas de liberação gradual associado ao composto orgânico pode favorecer o uso mais racional, devido à matéria orgânica proteger esse nutriente da fixação no solo. Dessa forma, objetivou-se com este trabalho avaliar o efeito de fontes de fósforo associadas à aplicação de compos

3. Apatite multi-generations in the Três Estradas Carbonatite, Southern Brazil: physical and chemistry meaning and implications to phosphate ore quality
Abstract Carbonatites were recently discovered in Southern Brazil, which increased the interest to evaluate the economic potential of these uncommon rocks, especially the Três Estradas Carbonatite. Carbonates are the dominant minerals of fresh rock followed by apatite, but the weathering process makes apatite abundant. We focused on apatite from the carbona

4. Utilization and fate of phosphorus of different sources applied to cohesive soil of Amazonian periphery
ABSTRACT In the Amazonian region, P is often a primary factor limiting sustainable agrosystems. We compared the efficiencies of local aluminous phosphate (ALP) and single superphosphate (SSP) under a cover of leguminous residues to determine the fate of P sources in an Amazonian soil with hardsetting characteristics. The experiment followed a randomized bloc

5. 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,

6. Biofertilizante de rochas mais matéria orgânica inoculada com bactéria diazotrófica na cana-de-açúcar.
Sugarcane (Saccharum spp.) Is currently considered one of the most important crops in the Brazilian social and economic. In Pernambuco, the sugar cane industry occupies an important agricultural area with high sugar and ethanol, generating many direct and indirect jobs. For increased productivity becomes necessary the use of management technologies that fost

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. Dinâmica do fósforo em latossolo do cerrado sob sistema de integração lavoura-pecuária
The integration of crop-livestock systems (ILP) is one of the alternatives to recover the fertility of soils under degraded pastures in the Cerrado region. This system has positive effects on soil fertility and quality, increasing organic carbon contents and soil biological activity, thus requiring a new characterization of soil fertility by identifying soil

10. Corn fertilization with ammonium sulfate in a Brasília Cerrado soil under Brachiaria decumbens pasture. / Fertilização com sulfato de amônio na cultura do milho em um solo de cerrado de Brasília sob pastagem de Brachiaria decumbens.
Crop/livestock integration systems have been adopted in the cerrados, since this is a technology for pasture recovery and renovation, used in association with annual crops, such as corn. In this system, the pasture is recovered and maintained productive by crop fertilization. Nitrogen is prominent among the nutrients applied in fertilizations; it undergoes s

11. Agronomic efficiency of nitrogen sources and fertilizers associations on deferment process of Brachiaria brizantha cv Marandu pastures. / Eficiência agronômica de fontes nitrogenadas e de associações de fertilizantes no processo de diferimento de Brachiaria brizantha cv Marandu.
The present research was conducted, from March through November 2003, to evaluate the efficiency of different nitrogen sources and fertilizers combinations on the deferment process of B. brizantha cv. Marandu upon forage production and applied nitrogen recovery along the growing, grazing and regrowth phases, besides the grazed forage nutritive value and the
