Effect of chemical and organic fertilizers on the aggregation of a soil grown with Musa acuminata AA
Aggregate stability is defined as the persistence of its particles, against destructive forces (climatic factors and anthropogenic activity). The aim of this research was to analyze the effect of fertilization on the structural stability of a soil grown with baby banana (Musa acuminata AA). This research was carried out in Manila and Asobaicotol farms (Icononzo, Tolima Department, Colombia); a randomized complete block design with four replications and eight treatments were performed; including compost, mycorrhiza, mineral fertilizers, fertilizer 17-6-18-2 (60 to 100g) and an absolute control (without fertilization). These soils performed medium aggregation (aggregated> 0.55mm) with values about 38.8%, percentage of aggregates extremes, among 40 - 50% and an aggregate stability about 80%; which allows classifying as very stable soils. The soil samples that received complete fertilization, compost + mycorrhiza and 60g of fertilizer 17-6-18-2; presented structural stability, class 3. MWD (Medium Weighted Diameter) higher values were obtained using only compost and mixed with mycorrhiza; in contrast, soils receiving mineral and chemicals fertilizers, showed poor structuring (MWD <0.5mm). Using the GMD (Geometrical Medium Diameter) more uniform values are observed than with the MWD. Finally, under all treatments, aggregates with diameter >0.75 mm did not exceed 50% and conversely, soil samples showed 20 - 30% of aggregates with diameter <0.25 mm. The results obtained allow show the positive effect of the application of compost and mycorrhiza on soil aggregation under study.

La estabilidad de agregados se define como la persistencia de sus partículas, frente a fuerzas destructivas (factores climáticos o acción antropogénica). El objetivo del presente estudio fue analizar el efecto de la fertilización sobre la estabilidad estructural de un suelo cultivado con bananito (Musa acuminata AA). Esta investigación se realizó en las fincas Manila y Asobaicotol (Icononzo, Tolima); empleándose un diseño de bloques completos al azar con cuatro repeticiones y ocho tratamientos; que incluían compost, micorrizas, fertilizantes minerales, fertilizante 17–6–18–2 (60 y 100g) y un testigo absoluto (sin fertilización). Estos suelos presentaron agregación media (agregados >0,55mm) con valores de 38,8%, porcentaje de agregados extremos entre 40 – 50% y una estabilidad de agregados del 80%; clasificándolos como suelos muy estables. Las muestras de suelo que recibieron fertilización completa, compost + micorrizas y 60g de 17–6–18–2; presentaron estabilidad estructural clase 3. Los valores más altos de DPM (Diámetro Ponderado Medio) se obtuvieron con uso de solo compost y mezclado con micorrizas; en contraste, suelos que recibieron fertilizantes minerales y químicos presentaron mala estructuración (DPM <0.5mm). Mediante el uso del DGM (Diámetro Geométrico Medio) se observan valores más uniformes que con el DPM. Finalmente, bajo todos los tratamientos, agregados con diámetro >0,75mm no superaron el 50% y por el contrario, las muestras de suelo presentaron entre 20 – 30% de agregados con diámetro <0,25mm. Los resultados obtenidos, permiten evidenciar el efecto positivo de la aplicación de compost y micorrizas sobre la agregación del suelo bajo estudio.
