“…The clear effect of TSP resulted from the following: (i) the high solubility of this fertilizer; (ii) the surface application, which decreases the fertilizer contact with soil, causing less dissolution of water-insoluble sources (RP and MTP) in a short period of time (CHIEN et al, 2011); and (iii) the pH value (5.3) in the 0-5 cm layer, which fell within the pH range shown to favor the dissolution of the TSP granules and enable a greater P release into the solution (pH range of 5.0 to 6.2, 0.01 mol L -1 calcium chloride (CaCl 2 ) (RAIJ, 2011). Thus, higher yields and accumulations of P were found in the forage in the first study year when using the application of TSP, which corroborates findings by Prochnow et al (2003) and Oliveira, Oliveira and Corsi (2007).…”

-The aim of this study was to assess the effects of the sources and levels of surface-applied (broadcast) phosphorus (P) when sowing the winter annual forages on phosphorus accumulation and yields of maize, soybean, black oat and annual ryegrass crops in a crop-livestock integration system over three years. (2010/11) and the accumulation of P in these crops were assessed. TSP provided the highest yield of total dry matter (TDM) and P accumulation only for black oat in the first year of cultivation. In the second year, MTP resulted in higher P accumulation than occurred with the other P sources in annual ryegrass and soybean, and both MTP and TSP provided higher P accumulation and grain export. In the third year, MTP provided a higher TDM yield and P accumulation for both the black oat and maize crops, resulting in the greatest residual effect over time.

“…Segundo Oliveira et al (2007), a baixa disponibilidade do P é um dos fatores mais restritivos para a pecuária, uma vez que as plantas forrageiras podem ser muito exigentes em P, em virtude de uma maior produção de biomassa, consequente à maior extração e exportação desse nutriente.…”

Eficiência de genótipos de, enquanto com aplicação de P foram de 9,4; 10,6; 11,9 e 8,4g vaso -1 , respectivamente. Para as variáveis MSF e MSPA, o P promoveu incremento da produção de todos os genótipos, produzindo em média 2,1 e 2,8g vaso -1 , respectivamente, sem o fornecimento de P, ao passo que, com o fornecimento de P, produziu 3,8 e 5,5g vaso -1 , respectivamente, para MSF e MSPA. Os genótipos Arapoty e B5 foram os mais eficientes no uso de P. O genótipo B12 apresentou maior adaptação para cultivo em solos com baixas concentrações de P, enquanto a variedade Arapoty sobressaiu-se quando realizada aplicação de adubo fosfatado. A variedade Arapoty e o genótipo B5 apresentaram maior eficiência no uso de P, podendo-se indicar esses materiais para programas de melhoramento dessa espécie.Palavras-chave: eficiência agronômica, forragicultura, nutrição de plantas (Arapoty, Capiporã, Marandu, and Piata Xaraés) ABSTRACT This study aimed to evaluate biomass production and agronomic efficiency as a result of the supply of phosphorus in different genotypes of Brachiaria brizantha. The experimental design was completely randomized, with eight treatments consisting of five varieties

“…However, the imminent depletion of phosphate rock reserves in the next century [58], and the use of P rates greater than the ability of the soil to retain can make it polluting in water, make the use of phosphate fertilizers to be minimized and used more efficiently. The low availability of P is one of the most restrictive factors for livestock, since the forage plants can be very demanding in P, due to a higher production of biomass, consequent to the greater extraction and export of this nutrient [12].…”

“…The potential to improve biomass production through P-fertilizer is quite evident due to P deficiency in highly weathering soil of tropical climate. The replacement of P extracted by grazing animals is not accomplished as it should be [12]. Phosphorus fertilizer in forages improves its capacity of tillering associated with faster and higher biomass production.…”

The aim in developing this work was to summarize information about phosphorus (P) limitation and dynamic in tropical soils for forage grasses production. The major idea is direct information about limited factors affecting P availability, dynamic of P fractionation, P pools, P forms, P use efficiency, and the 4R's Nutrient Stewardship' for P-fertilizer in forage grasses. Organizing these sub-headings in a chapter can result in interesting of how P behaves under tropical soils, in order to take decision to manage P-fertilizer to accomplish forage grasses production with social, economic, and environmental benefits. As the most limiting nutrient in tropical soils, P-fertilizer in forage grasses can be more effective if the best management practices are followed. In order to avoid excess P-fertilizer application in soil or P-fertilizer response with low efficiency, it is important to understand the P dynamic and the factors associated with P adsorption in soil. Even with low amount of P requested to forages species, the P available in soil is quite low, and this knowledge is primordial to direct P-fertilizer. Tropical soils are quite limited in P content, due to the natural formation with parental material poor in P content and highly weathering condition. Thus, in order to improve phosphorus use efficiency, the 4R's must be followed to improve P use efficiency (PUE). It is not easy to improve PUE in highly weathering soil with high buffering capacity; however, all the combination of best management practices for P-fertilizer application can result in better use efficiency. Based on the scarcity of natural P-sources in the whole world, the use of alternative P-sources should be incentivized, and more researches about this issue are need for better understanding.
