“…Moreover, humic acids improve soil structure and soil fertility, the metabolisms of soil microorganisms, and nutrient uptake. In addition, it enhances the water-holding capacity of the soil, leading to exceptional plant growth and micronutrient uptake (Ouni et al, 2014b;Plaza et al, 2015). Table 4 illustrates the statistically significant (p < 0.05) differences among all BOR and humic acid (HA) levels on soil nitrogen (N) composition.…”

A field trial was conducted to evaluate blends of organic resources and humic acids, in order to enhance organic berseem forage production. The objective of this study was to compare an EM.1 (effective microorganisms)-treated blend of organic resources with an untreated blend of organic resources, and thereby evaluate the usefulness of humic acid as an organic fertilizer. The two types of blends,each with 4 application levels(0, 15, 30, and 45 t·ha −1 ), and humic acid (4 application levels: 0, 15, 30, and 45 kg·ha −1 ) were evaluated using a randomized complete block design with a split-plot arrangement (blend types were the main plot factor and humic acid a sub-plot factor). Except for the difference in EM.1 inoculation, both blends were prepared by co-composting cow manure, poultry manure, and kitchen waste (2:1:1 ratio by volume, respectively). The differences among treatments with respect to fresh and dry yield, as well as mineral composition were recorded. The blend treated with effective microorganisms was found to be a more effective fertilizer than the untreated blend. Additionally, heavier application of both types of organic resource blends and humic acid enhanced both fresh and dry yields, and improved the mineral composition of the crop. These findings are valuable for organic growers and it may open a new avenue for researchers worldwide.

Purpose Sugarcane vinasse is generated in large amounts and can be utilized to improve soil attributes, especially in areas degraded by burns. The aim of the present study was to evaluate the effects of sugarcane vinasse on physico-chemical attributes of a Cambisol managed via annual burns. Methods Soil samples were collected from an annually burned area under pasture and used in an experiment in pots to evaluate the effects of dosages of vinasse (0, 18.8, 37.5, 56.3, 75.0, 112.5, and 150 ). The water-dispersible clay was reduced by the formation of bonds with organic matter, which overlapped the repulsive forces intensified by the increment of K + /(Ca 2+ + Mg 2+ ). The estimated vinasse dosage that provided the minimum water-dispersible clay (69 g kg −1 ) was 110 m 3 ha −1 . Conclusions Vinasse can be applied to improve the physico-chemical attributes of soils degraded by annual burns.

“…Mg 2+ is a flocculant ion due to its relatively high capacity to compress the electric double layer, explaining the positive coefficient (Table 4) (ARIENZO et al, 2012;MAHANTA et al, 2012;MARCHUK, 2011). K + is a dispersant ion and the positive correlation with flocculation degree was not expected .…”

“…The increase in K + Mg 2+ and K + also correlated with the flocculation degree in sandy soil. Mg 2+ is a flocculant ion due to its relatively high capacity to compress the electric double layer, explaining the positive coefficient (Table 4) (ARIENZO et al, 2012;MAHANTA et al, 2012;MARCHUK, 2011).…”

“…Clay flocculation is the initial process of soil aggregation and is mainly affected by electrostatic forces (CARDOSO et al, 2013;CHOROM;RENGASAMY, 1995). Organic matter also influences flocculation, or by the formation of bridges between particles, favoring their union or increasing the density of negative charges, favoring repulsion in electronegative soils and reducing its structural stability (LEE et al, 2015;PLAZA et al, 2015).…”

Vinasse is a potassium-rich waste generated in large amounts by the ethanol production that, applied in the soil, can promote changes in water dispersible clay and in its physical quality. The aim of this study was to evaluate the clay dispersion of Oxisols after vinasse application and correlate it with some chemical attributes. ResumoA vinhaça é um resíduo rico em potássio gerado em grandes quantidades pela produção de etanol que, aplicada ao solo, pode promover mudanças na dispersão de argila em água e em sua qualidade física. O objetivo desse estudo foi avaliar a dispersão de argila em Latossolos após a aplicação de vinhaça e correlacioná-la com alguns atributos químicos. Amostras foram coletadas em dois Latossolos (155 e 471 g de argila kg -1 ), alocadas em vasos e permaneceram incubados por 120 dias após receberem doses de vinhaça (0, 50, 100, 150
