| dc.description | This document deals with the effect of the application of Humic Acids on the structure of sandy loam soils. The objectives were to detail the physical properties of sandy loam soils and establish the benefits of the application of humic acids in sandy loam soils. The conclusions determined that a soil with a composition of 60% sand particles, 30% silt particles and 10% clay particles is classified as having a sandy loam texture. Humic acids induce chemical modifications in the sorption properties of the soil. Balance acidity and alkalinity levels in soils to adjust the proper pH. Humic acids prove to be an effective stimulant of root development. Organic humic amendments with a high content of Iron (Fe) assimilable by plants are recommended for the correction of basic, calcareous soils, low in organic matter and/or saline. These amendments provide plant-assimilable iron (Fe) in the form of ferrous sulfate, reduce iron (Fe) accumulation in the soil, prevent and alleviate iron chlorosis, mitigate soil erosion in sandy soils due to excessive rainfall, and have a cushioning effect on the soil. pH, promotes the formation of soil clay-humic complexes, improves cation exchange capacity (CEC), improves nutrient absorption, supplies a full spectrum of chelated micronutrients, chelates salts locked in the soil for assimilation and improves physical, chemical and biological properties. soil properties. | es_ES |

| dc.description.abstract | El presente documento trata sobre el efecto de la aplicación de Ácidos Húmicos sobre la estructura de los suelos franco arenosos. Los objetivos planteados fueron detallar las propiedades físicas de los suelos franco arenosos y establecer los beneficios de la aplicación de ácidos húmicos en suelos franco arenosos. Las conclusiones determinaron que un suelo con una composición de 60 % de partículas de arena, 30 % de partículas de limo y 10 % de partículas de arcilla se clasifica como poseyendo una textura franca arenosa. Los ácidos húmicos inducen modificaciones químicas en las propiedades de sorción del suelo. Equilibrar los niveles de acidez y alcalinidad en los suelos para ajustar el pH adecuado. Los ácidos húmicos demuestran ser un eficaz estimulante del desarrollo radicular. Las enmiendas húmicas orgánicas con alto contenido de Hierro (Fe) asimilable por las plantas se recomiendan para la corrección de suelos básicos, calcáreos, bajos en materia orgánica y/o salinos. Estas enmiendas proporcionan hierro (Fe) asimilable a las plantas en forma de sulfato ferroso, reducen la acumulación de hierro (Fe) en el suelo, previenen y alivian la clorosis férrica, mitigan la erosión del suelo en suelos arenosos debido a lluvias excesivas y tienen un efecto amortiguador en el suelo. pH, promueve la formación de complejos arcilloso-húmicos del suelo, mejora la capacidad de intercambio catiónico (CIC), mejora la absorción de nutrientes, suministra un espectro completo de micronutrientes quelados, quela las sales bloqueadas en el suelo para su asimilación y mejora las propiedades físicas, químicas y biológicas. propiedades del suelo. | es_ES |
