Efecto de fertilizantes químicos y orgánicos sobre la agregación de un suelo cultivado con Musa acuminata AA

Abstract: 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 (<em>Musa acuminata</em> 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 tratamie… Show more

“…Physical analysis was performed in triplicate using a stability analysis of aggregates by the Yoder method (Le Bissonnais, 2016). The structure index (SI) was calculated taking into account equation 1, where SI: structure index, W 1 :% of stable aggregates with diameter > 2 mm, W n :% of stable aggregates with diameter < 0.25 mm, W 2 , W 3 , W 4 , … of stable aggregates in each of the size ranges used, between 2 and 0.25 mm in diameter (Cardona et al, 2016). Mean weighted diameter (MWD) was calculated as described in equation 2, where X i is the mean diameter of the corresponding size fraction and w i corresponds to percentage by weight of a respective aggregates fraction from a certain size range (Ghezzehei, 2012).…”
