Upland soils in the region are sandy and largely glacial in origin and consist largely of entisols and spodosols
From Oxisols to Spodosols
and Histosols: evolution of the soil mantles in the rio Negro basin (Amazonia).
The Cook Inlet Lowlands are 38% Spodosols
and 23% Histosols (USDA NRCS, 2004).
Forms and profile distribution of soil phosphorus in alpine Inceptisols and Spodosols
Soil type has been related to buttressing in Malaysia where buttressing has been found to be more common and more massive on loams and clayey soils than on sandy spodosols
The main soil types are Spodosols
, Neosols, Quartzenic, Hydromorphic and Organosols (RODERJAN et al.
Comparing fumigant retention of polyethylene mulches for nutsedge control in Florida spodosols
Lo anterior conduce a considerar la recuperacion de la Bav de los bosques de este estudio como similar al de otros bosques del tropico americano cuando la sucesion se produce sobre suelos quimicamente pobres o sujetos a erosion, aunque no extremadamente pobres como los Ultisols (Saldarriaga 1994) y Spodosols
amazonicos (Jordan 1989, Johnson et al.
Influence of oxalate loading on phosphorus and aluminum solubility in spodosols
Length of irrigation and soil humidity as basis for delivering fumigants through drip lines in Florida spodosols
Now, for Oxisols and Ultisols of the humid tropical and subtropical climates and Andisols, Spodosols
, and part of the Inceptsols soil orders (SOIL SURVEY STAFF, 1994) with predominant pH dependent charge associated with the presence of kaolinite and amorphous and crystalline iron and aluminum oxides, subsurface soil horizons have usually small content of SOM and are usually more acid, favoring the predominance of anion exchange capacity (AEC) that will retain the N-N[O.
