Contribución al estudio del fósforo en suelos ácidos. 1: Características de adsorción y fracciones de fósforo en una tierra parda del noroeste de España.
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1981-07)P adsorption isotherm and P fractions were used to study the P adsorption characteristics of an acid brown soil from Galicia (North West of Spain). Adsorption data were adjusted to Freundlich, Langmuir, and Gunary equations, ... -
Uso de la isoterma de adsorción para evaluar requerimientos de fósforo, 1: Isotermas de adsorción de los suelos [Venezuela].
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1981-07)The principal aim of this research work is to determine the phosphorus fertilizer requirements in some Venezuelan soils. The chosen soils were contrasting in both chemical and textural characteristics. The method consisted ... -
Uso de la isoterma de adsorción para evaluar requerimientos de fósforo, 2: Determinación con base en los datos de adsorción, del requerimiento externo de fósforo para Vigna unguiculata L. var. Tuy [suelos, Venezuela].
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1981-07)The external phosphorus requirement for Vigna unguiculata L. var. Tuy (Frijol bayo) was determined in pot and field experiments The chosen soils were corrected for macro and micro-nutrients deficiences using the corresponding ... -
Uso de la isoterma de adsorción para evaluar requerimientos de fósforo, 3: Comparación con otros métodos.
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1981-10)A comparison of the yield of Vigna unguiculata L. var. Tuy (Frijol bayo) as predicted by a traditional extraction method (Mendell reagent) and two methods which make use of the sorption characteristics of the soils are ...
