Última Application of superphosphate complexed with humic acid in an area of sugarcane Rev. Ciênc. Agron. Zavaschi,Eduardo; Ferraz-Almeida,Risely; Fária,Letícia Abreu; Otto,Rafael; Vitti,André César; Vitti,Godofredo Cesar. ABSTRACT In tropical soils, the efficiency of phosphorus (P) fertilization is low, due to P adsorption on the surface of the clay. Superphosphate complexed with humic acid (SSP+HA) is presented as an alternative for improving P use efficiency and crop yields. The aim of this study was to investigate SSP+HA performance in sugarcane production including increases in plant dry matter (DM) and P content. The experiment was conducted with two sources of P (simple superphosphate - SSP, SSP+HA) and five doses (0, 45, 90, 135 and 180 kg ha-1 P2O5). The dose of 135 kg ha-1 P2O5 was used to explain the residual effect of P, collecting soil samples from the plant cane and first ratoon. Stalk, top and root samples were collected to determine DM and P content; both... Tipo: Info:eu-repo/semantics/article Palavras-chave: Soil fertilization; Phosphorus adsorption; Phosphorus dynamics.

(Palmira) Serna-Posso *,Eduardo José; Sánchez-de Prager,Marina; Cisneros-Rojas,Carlos Adolfo. Abstract: It has been established that organic acid secretion by rhizosphere microorganisms is one of the mechanisms to solubilize the phosphorus (P) attached to insoluble mineral compounds in soil. This action is an important biotechnological alternative, especially in those soils where high fixation of this nutrient occurs, a very common situation in the tropics. This research evaluated the ability performed by five bacterial and five fungal isolates from Typic Melanudands soil to produce organic acids and generate available phosphorus from insoluble P sources. Given these concerns, the selected microorganisms were replicated for 7 days in liquid medium Pikovskaya (PVK) modified sources tricalcium phosphate (P-Ca), aluminum phosphate (P-Al) and iron...
