“…The available P level (anion exchange resin) in the soil at experiment establishment was considered low in the 0-5 (8.1 mg kg −1 ) and 5-10 (9.7 mg kg −1 ) cm layers, and very low in the 10-20 (4.8 mg kg −1 ) cm layer according to Raij et al (1997). Iron oxide content, mineral assemblage by X-ray diffraction and P maximum adsorption capacity (2201 mg kg −1 ) were also determined in a soil sample collected from the 0-20 cm layer before trial establishment and the results are accessible at Teles et al (2017).…”

“…To investigate the changes in the proportions of total P in different P fractions with time (Figure 1), data of 2009 and 2011 were obtained from Teles et al (2017), data of 2014 were retrieved from Soltangheisi et al (2018), and data of 2017 are the results of the current study. Each small square represents 1% of total P. Labile, mod-labile, and non-labile P fractions were shown with the shades of green, blue, and brown colors, respectively.…”

Use of cover crops in an integrated agricultural system can reduce demand of inorganic phosphorus (P) fertilizers, where the subsequent crops can take up P accumulated in cover crops biomass after the decomposition. In this research we hypothesized that some cover crops can take up P from less labile fractions and recycle it back to the soil through plant residues resulting in better P use efficiency of the system; cover crops are capable of P uptake from subsurface layers which leads to the accumulation of this P on the surface after the decomposition of their residues; and cover crop species respond differently to distinct inorganic P sources. To examine these hypotheses, a field experiment was conducted over nine successive years in South Brazil. The experimental treatments were established as a split-plot randomized block design, in a 3 × 6 factorial scheme, considering three P treatments [no-P, single superphosphate (SSP), and rock phosphate (RP)] as main plot and six cover crop treatments (common vetch, white lupin, fodder radish, ryegrass, black oat, and a fallow) as subplots. Soil samples were collected from the depths of 0-5, 5-10, and 10-15 cm and analyzed by Hedley P fractionation. In P-unfertilized cropping system, the amounts of labile and mod-labile P fractions were not modified by cover crops related to fallow. When inorganic P fertilizers were applied, the amount of labile and mod-labile P pools under fallow were higher than under cover crops in 5-10 cm depth. Black oat and common vetch cycled more labile P under SSP and RP, respectively. Common vetch and ryegrass resulted in the highest accumulation of organic P on the surface under SSP and RP, respectively. Black oat was capable to change P extracted by 1.0 M HCl to more labile forms. Fodder radish showed the highest P uptake in comparison with other cover crops. The higher P balance efficiency of the system was achieved under SSP in comparison with RP application but it seems that cover crops are more effective at improving the efficiency under RP compared to SSP.

“…The referred deficiency is found when the efficiency of P recovery, that is, what returns to plant production, is between 5 to 25% of what is applied (Yang et al, 2013). This fact justifies the large amounts of phosphate fertilizers used in Brazilian soils (Teles et al, 2017). Especially in the central portion of the Amazon, the processes of adsorption and availability of P are more intense in relation to other regions of the country, mainly due to the climate conditions, marked by high rainfall and high temperature, as well as by the material of poor origin present (Novais et al, 2007;Melo & Alleoni, 2009;Cravo et al, 2012).…”

Amazonian soils have some physical, chemical and mineralogical differences, understanding the differences is important to understand the behavior of nutrients in the soil, especially phosphorus. The study was carried out in two types of soils: a Hydromorphic soil profile and a Non-hydromorphic soil profile in the Central Amazon region of Brazil, located in the metropolitan area of Manaus. Five depths were sampled: 0.00-0.05; 0.05-0.1; 0.1-0.2; 0.2-0.4; and 0.4-0.6 m. Physical, chemical, mineralogical and morphological attributes of both soils were studied. With the exception of clay, the levels of sand and silt remained stable in depth. The levels of organic matter gradually decrease in depth. The pH in water and in KCl, ∆pH, point of zero load, were similar between the surface and subsurface soils. Al 3+ , H + +Al 3+ , CECt, CECT and clay activity were similar in Non-hydromorphic soil and increase in surface (< 0.2 m) and stabilize in subsurface (> 0.2 m). In both soils, the bases are reduced in subsurface (> 0.2 m). Aluminum and iron oxalate reduce with greater expressiveness in Non-hydromorphic soil. Aluminum and dithionite iron exhibit the same behavior. The levels of Goethite (Gt) and Hematite (Hm) are high in depth in the Non-hydromorphic soil and decrease in the Hydromorphic soil. There are sensitive distinctions between soils, due to the imposed edaphoclimatic conditions.

“…O fosfato de Araxá (24% P2O5 e 4% solúvel em ácido cítrico 2%) é uma fonte inorgânica de fósforo, de origem ígnea, e baixa solubilidade devido a pouca capacidade de substituição isomórfica (HAMMOND et al, 1986). O fosfato de Araxá está incluso entre os fosfatos naturais aos quais se subdividem em reativos e pouco reativos e podem ou não exibir efeito residual em solos tropicais brasileiros (CAIONE et al, 2015;TELES et al, 2017). O fósforo presente no fosfato de Araxá está quimicamente complexado e para ser disponibilizado para a solução do solo é necessário a ação de metabólitos de baixo peso molecular (normalmente ácidos orgânicos), sobretudo de origem microbiana, processo conhecido como solubilização (REZA et al, 2016).…”
