Correlación entre aptitud relativa y rendimientos estimados en los suelos de la zona regable del Viar, Sevilla

Abstract

[IT]: Si discutono le possibilità per potete utilizzare un sistema di valutazione che pronostica la attitudine relativa dei suoli per determinate coltivazioni. I risultati ottenuti dalla applicazione del sistema ai suoli della zona irrigabile del Viar (Siviglia) furono analizzati per correlazione semplice con le rendite date dagli agricoltori. Correlazioni significative furono ottenute tra le rendite calcolate con il sistema di valutazione e quelle di riferimento, per le coltivazioni di grano, mais, cotone, barbabietola da zucchero e soia. Per tutte le coltivazioni nell'insieme il coefficiente di correlazione fu molto prossimo alla unità. Da questa analisi statistica e dal numero di suoli considerati si può concludere che il sistema di valutazione discusso potrebbe essere utilizzato per pronosticare l'attitudine relativa dei suoli per le coltivazioni analizzate.

[ES]: Se discuten las posibilidades de utilización de un sistema de evaluación que pronostica la aptitud relativa de los suelos para determinados cultivos. Los resultados obtenidos de su aplicación en suelos de la zona regable del Víar, Sevilla, se analizaron mediante correlación simple con los rendimientos estimados por los agricultores de la zona. Correlaciones significantes se obtuvieron entre los rendimientos pronosticados y aquellos de referencia, para los cultivos de trigo, maiz, algodón, remolacha y soja. Para el conjunto de todos los cultivos analizados, el coeficiente de correlación alcanzó un valor próximo a la unidad. En base a este análisis estadístico se llegó a la conclusión de que el discutido sistema de evaluación podría ser utilizado para pronosticar la aptitud relativa de los suelos para los cultivos analizados.

[EN]: The feasibility of applying a soil evaluation system which predicts the relative soil suitability for several crops was discussed. Results obtained by its application in soils of the Viar irrigation area, Sevilla, were related through linear correlation to those estimated by local farmers. Significant correlations were obtained between predicted yield values and the reference data for production of wheat, corn, cotton, sugar beet and soybean. In all the crops, the correlation coefficient was close to 1.00. Based on the statistic analysis, it was concluded that this soil evaluation systema may be used to evaluate relative soil suitability for specific crop production.
