[ES]En el presente trabajo se estudia la influencia del tipo de suelo sobre la composición y distribuciónn de nutrientes minerales en alfalfa, ecotipo Aragón, cultivada, en régimen de regadío sobre suelos pardo de costra caliza, sobre suelo poco evolucionado sobre sedimentos de margas y sobre suelo aluvial de vega. El material vegetal fue recogido a lo largo de dos ciclos de explotación (1970 y 1971) completando un total de diez cortes, realizados cuando la alfalfa se hallaba en un 10% de floración. Se estudia la distribución en hoja y tallo de nitrógeno, fósforo, potasio, calcio, magnesio, hierro, manganeso, cobre y zinc. Según los resultados obtenidos se puede afirmar que el tipo de suelo tiene influencia sobre la composición y distribución de los elementos minerales en la planta de alfalfa.
[EN] In this work we study the influence of the type of soil on the composition and distribution of mineral nutrientes in the Alfalfa Aragon's ecotype, growing under irrigated soils: Brown soil with calcareous crust (Terrace soil), Undeveloped Soil on marls sedimentation (Serosem) and Alluvial Soil (Ribera soil). The plant material corresponding to ten cuttings, was harvested along two management cycles (1970 and 1971). The cuttings were made at the 10% flowering stage. We study the distribution of N, P, K, Ca, Mg, Fe, Cu, Mn and Zn, in both, leaf and stem. Acording to our results we can tell that the type of soil has a influence on the composition and distribution of mineral nutrientes in the alfalfa.
