“…The Pi-NaOH 0.5 fraction was the majority buffering of the labile fractions, and lower clay content explain the generalized reduction of Pi-NaOH 0.5 fraction, which is the most labile fraction observed. As observed by Santos et al (2008) and Alovisi et al (2016), the lower labile fraction participated in P supply for plants, proved by its decreasing in total P through time of P-fertilizer.…”

“…P distribution in soil is present in net crystalline of some soil mineral until more stable fractions as organic matter, which compose the total P fractions in soil that is constituted of organic and inorganic fractions. These organic and inorganic P fractions in soil are present under dynamic balance (Alovisi et al, 2016). P adsorption is directly correlated with clay content in soil due to capacity of P adsorption in broken face of silicate clay as well as iron (Fe) and aluminum (Al) oxi-hydroxide.…”

“…Researches related to concentration of silicate in soil solution can promote alteration in the characteristic of phosphate adsorption in soil, resulting in decreasing the intensity of P adsorption turn P more available for plant uptake (Menegale, Castro, & Mancuso, 2015). Thus, knowledge about ionic interaction and P forms distribution in soil can offer relevant information of P dynamic in soil and plant, improving the evaluation process of soil availability (Tokura et al, 2011;Alovisi et al, 2016). The knowledge of P dynamic can help in guide soil fertilizer recommendation for crops and the possible silicate affects can contribute for increasing P availability and possible decreasing P fertilizer rates.…”

Phosphorus is the most limited nutrient in Brazilian soils for plant growth, resulted of low availability and poor P content in bedrock. The aim of the study was to evaluate the dynamic of P fractions in a sand soil typical Quartzipsamment cropped with common bean under the effects of P and Si-fertilizer rates. The research was carried out in a soil with sand texture and clay mineralogy constituted mainly by kaolinite, classified as Neossolo Quartzarenico Ortico típico (RQo). The greenhouse location was the campus of Universidade Federal de Lavras located in the city of Lavras, state of Minas Gerais, Brazil (approximately 21o13'46.54" S and 44o58'26.30" W, average altitude 932 m above sea level). The experimental design used was entirely random, arranged in a 4 × 3 factorial design, with four repetitions, with amount of 48 experimental units. The treatments included four P rates (0, 80, 240 and 410 mg dm-3) and four Si rates (0, 240 and 410 mg dm-3). Phosphorus fractions in soil are little affected by Si-fertilizer rates. P uptakes by bean plants are correlated to the labile and moderately labile fractions. P-fertilizer rates increment majority the stable P fraction in soil and in lower proportion the labile and moderately labile P fractions in soil. Po-NaHCO3 is the only that contributes to bean plant nutrition.

“…Achat et al 1 the results show the dominant role of aluminum and iron oxides and organic carbon in the control of the dynamics of phosphate ions in acidic and non-acidic soils. Alovisi et al 2 showed that the effect of inorganic fertilizer on the moderate and labile P fractions was high. The NaHCO 3 -Po fraction in the organic P fractions was observed to be the only fraction that contributed to the plant nutrition.…”

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.
