“…Conversely, the plants that were not treated with humic substances presented an exponential decay with the increasing nitrogen levels ( Figure 2D). The reduction of fruit soluble solids as a function of an increasing nitrogen level was previously reported by Silva et al (2002), and this reduction could be explained by the positive and direct effect of humic substances on the root absorption of ammonium nitrate (KEELING et al, 2003).…”

“…Agronomy Maringá, v. 37, n. 2, p. 211-218, Apr. involved in cell respiration, photosynthesis, protein synthesis, water and nutrient uptake, enzyme activities (NARDI et al, 2000;TAHIR et al, 2011) and hormones (TREVISAN et al, 2010), thus stimulating plant growth. Humic substances, when applied directly onto the soil or substrate, have been used for plant production because these substances improve soil fertility and nutrient availability, according to Eyheraguibel et al (2008).…”

“…Pant et al (2009) found that the use of VCT had a greater effect on plant height under VC fertilization, and had much smaller effect on plant height under Osmocote fertilization. Additionally, Keeling et al (2003) and Siddiqui et al (2008) observed that application of VCT and compost tea on oilseed rape plant and okra plants, increased root development, plant growth and tap root length, respectively; although we did not measure root growth and nutrient uptake, plants grown in F4 and F5 showed better plant height and nutrient uptake compared to control plants, suggesting that these two variables might be part of the mechanisms involved in plant growth stimulation. Our results might be due to the presence of the VC and the VCT, materials that provide higher quality than manure generated by traditional methods of composting (Santamarí a-Romero et al, 2001;Panikkar et al, 2004;Lopes-Pereira et al, 2005).…”

“…Los mejores resultados se han encontrado con los extractos obtenidos de composts maduros en combinación con la fertilización mineral, con los que se observaron incrementos significativos en el crecimiento de colza (Brassica napus L.) bajo solución nutritiva; sin embargo, el efecto promotor de los extractos disminuyó rápidamente a unas proporciones superiores a 1:3 v:v en agua (Keeling et al, 2003). En este mismo sentido, Gramss et al (2003) con extractos de guisante (Pisum sativum L.) (9,8 g de peso seco/L de agua) aplicados una sola vez a 0,7 L/kg de suelo en el sistema de riego en diferentes especies cultivadas bajo sistemas de producción ecológica, encontraron que los extractos incrementaron respecto al tratamiento control, el peso fresco de plantas entre un 38 a un 84%.…”

“…De esta manera, el efecto de los extractos sobre el crecimiento y nutrición de los cultivos es usualmente atribuido tanto a su contenido y aportación de nutrientes como de sustancias húmicas, hormonales y otras sustancias (Gramss et al, 2003;Ayanlaja et al, 2001;Keeling et al, 2003).…”
