Evaluación paramétrica de suelos para usos agrícolas: II. Modelos de regresión polinomial para calcular la productividad

Abstract

[ES]: Se establece una aproximación a un sistema paramétrico de evaluación de suelos según su productividad agrícola. A partir de datos correspondientes a una zona de referencia, en la provincia de Sevilla, y siguiendo un procedimiemo de modelación estadística, se computaron modelos de regresión polinomial para interpretar la influencia de características edáficas seleccionadas sobre las producciones de trigo, maíz y algodón. De acuerdo con los resultados del análisis estadístico, los modelos tienen elevadas posibilidades de aplicación en el cálculo de la capacidad productiva de los suelos.

[EN]: An approach to a parametric soil evaluation system according to its agricultural produtivity was estalblished. A range of Sevilla soils constituted the experimental basis. Applying a statistical modeling procedure, it was computed polynomial regression models in order to interpret the influence of selected soil characteristics on the productions of wheat, field corn, and cotton. Results of the statistica1 analysis suggest that application of these models could be used to evaluate the soil productive capacity.

[IT]: Si è stabilita l'approssimazione ad un sistema parametrico della valutazione dei suoli secondo la loro produttività. Dai dati corrispondenti ad una zona della provincia di Siviglia, e secondo un procedimento di modellazione polinomiale per interpretare l'influenza delle caratteristiche pedologiche selezionate sulle produzioni di grano, mais e cotone. D'accordo con i risultati delle analisi statistiche, i modelli hanno eleva te possibilità di applicazione nel calcolo della capacità di produzione dei suoli.
