dc.description.abstractThe surly lands of the tropic, which fall into the company of the order of ultisoi and ocsisol are further overgrown, conceives In large quantities a colloid of unassigned variables, has ph Earth (soil: water 1:1) lower than 5.0 das have a capacity Low kation exchange (CTK) (usually smaller than 10 cmoles (+)kg-l With a very high level of base saturation and aluminum saturation, with high levels of above 80%.Phosphorus is available to low plants, just as calcium, calcium, and magnesium are exchanged. At sour sows, reactions between phosphate and nonbiological components of the soil involve the active surface of fe and al minerals Soil minerals like allofan, ferrihydrite and gutit, hematite and kaolinit Is a very reactive kind. The minerals together with the humus-al complex are probably the most active components reacting with phosphate in the sour soils. The capacity for phosphorous preparation (p) of clay minerals depends on many factors, including the large surface proportion it holds.Actually, caolinit (see 1:1) more p per unit of surface area than the mineral 2:1. Andil soils with high anion retention capacity, associated with high al and fe compounds.Compound po4 retention by soil minerals varies in increase In order, hematite < gutit natural < ferrihydrit < allofan. Julah p Inorganic compounds extracted from fe And al varies by distribution and decline by sequence: allofan > fresh gel > gel pseodobumit fe > gel al al > aged gel gel The p covers 30 to 70 times more than giblies, and the gel fe deposits about 10 times more than the same crystalline mineral shape (hermatite, gutit, and acagenit). Key words: minereal clay, affecting, phosphorus, retentionen_US
