• Changes in root development of Arabidopsis promoted by organic matter from oxisols (2007, background): “…that relatively high (HA > 14 kDa) and low (FA < 700 Da) molecular weight HS can induce changes in Arabidopsis root development, and according to Muscolo et al. (2006), HS have very 208 Ann Appl Biol 151 (2007) 199–211 ª 2007 The Authors Journal compilation ª 2007 Association of Applied…”
• Plant biostimulants: physiological responses induced by protein hydrolyzed-based products and humic substances in plant metabolism (2016, background): “Although the recognized importance of IAA to HS to promote plant growth, there is clear evidence that the simple presence of auxin in the bulk HS is not sufficient to justify all plant physiological responses to these aggregates.”
• Rhizosphere humic acid interacts with root cell walls to reduce hydraulic conductivity and plant development (2010, background): “There, partial disruption of humic acid agglomerates by root secreted organic acids may then release individual growth regulatory molecules that are small enough to penetrate through the cell wall matrix to the cell membrane and effect changes in gene expression or enzyme activities (Piccolo et al. ”
• The Use of Biostimulants for Enhancing Nutrient Uptake (2015, methodology): “In recent studies, the specific chemical structure of the HS rather than the sizes of their molecules have been shown to affect the biological activity of the HS (Canellas et al., 2010; Muscolo et al., 2007).”
• Plant Biostimulants: A Categorical Review, Their Implications for Row Crop Production, and Relation to Soil Health Indicators (2021, background): “Humic acids can be derived from various sources, such as composted organic material, peat soils, and leonardite [34,35], and the source and stage of decomposition of the HA or FA influences the structure, composition, and its effect on crop and soil systems [36].”
