“…1). IER resin was placed at 0.5 m depth in order to capture nutrient availability in the active rooting zone, which has been determined to be from 0.2 to 0.6 m under micro-irrigation (Brown and Sanden unpublished data; Lepsch et al 2019;Vrugt et al 2001). Two PVC pipes were deployed within a treatment plot.…”

“…A poor understanding of how to manage OMAs in orchards limits their use and weakens the potential for improvement in soil fertility in these agroecosystems (Khalsa and Brown 2017). Although there have been many studies that have focused on the effects of OMAs in row crops and permanent crops in other regions, few have focused on how these amendments affect soil fertility in permanent crops in California (Baldi et al 2018;Blackshaw et al 2005;Canali et al 2004;Forge et al 2013;Gannett et al 2019;Lepsch et al 2019;Peck et al 2011). Understanding how surficial applications of OMAs influence nutrient dynamics in the short-term in permanent cropping systems poses different challenges than in annual cropping systems where OMAs are incorporated directly into the soil (Jackson et al 2003).…”

“…Amendment-driven changes in soil physical properties can increase soil water content (θ) and change the soil moisture potential (ψ) and characteristic curve (θ vs. ψ) of orchard soils. For example, soil moisture contents were increased between saturation and 100 kPa in response to fall-applied composted dairy solids in a sandy almond orchard soil [59] and over the growing season in response to applications of compost and spray-on paper mulch in an apple orchard [60].…”

“…En este sentido, un estudio realizado por Islam et al (2020) en el suroeste asíatico, demostró que las enmiendas orgánicas aplicadas en suelos inundables donde se produce arroz, disminuyen el estrés hídrico y aumenta la producción en comparación con fertilizantes químicos tradicionales. Estos resultados, son similares a los reportados por Lepsch et al (2019) en suelos de Norteamérica, donde encontraron que la adición de enmiendas aporta al suelo una mayor capacidad de sostener un contenido volumétrico de agua disponible para las plantas, incluso en épocas secas, debido a que los macroporos que se forman con la enmienda estabilizan el suelo, lo cual permite aumentar la producción de almendras.…”

“…Los abonos o enmiendas orgánicas son el resultado de procesos de descomposición y mineralización de residuos vegetales, animales e industriales, que aplicados al suelo, pueden ayudar a mejorar sus propiedades físicas, químicas y biológicas (Cervera-Mata et al 2018;Cesarano et al 2017;Islam et al 2020). De manera general, las enmiendas mejoran los procesos de infiltración y capacidad de retención del agua (Lepsch et al 2019), promueven la actividad microbiana y controlan el pH (Cesarano et al 2017;Cervera-Mata et al 2018) por lo que se consideran una importante fuente de nutrientes para el suelo y las plantas. Sin embargo, es necesario revisar el origen de dicho material, para evitar la adición de patógenos y elementos potencialmente tóxicos (Araya et al 2014;Martínez-Nieto & Chaparro-Rico, 2013).…”
