“…The increase of these groups is associated with the expansion of the diffuse double layer, which favors the dispersion of soil particles (WUDDIVIRA & CAMPS-ROACH, 2007). Evaluating clay dispersion and aggregation in a Latosol with application of pig and poultry manure, BARBOSA et al (2015) reported that this long-term fertilization increased the proportion of microaggregates (<0.250mm), thus explaining the increase in clay dispersion. Native forest was strongly correlated with porosity, which may indicate high values of porosity, without depending of microporosity.…”

“…MELLEK et al (2010) tested increasing rates of liquid cattle manure on a Cambisolf or two years, and observed structural improvements in the soil, e.g., a reduction in density and increases in macroporosity and aggregate stability. BARBOSA et al (2015) evaluated aggregation in a Latosol after PS and PL application and observed an increase in aggregates of <0.250mm, between 30 and 60 days after fertilization, in the 0-10cm layer. Assessing changes in physical properties of a Latosol, Oliveira et al (2015) reported no changes after PS application in different soil management systems in the long term, but the land use systems adopted increased bulk density and penetration resistance and reduced the pore volume.…”

“…Oliveira et al (2015) observed that the applications of organic material, by means of swine manure, did not influence the soil structure and Barbosa et al (2015) observed in experiment of eight years duration in a Red Latosol (Oxisol), that the aviary manure improves the soil structure in the first 15 days after the application. As for the LL, the information is commonly directed to the works that evaluate the phyto-extraction of heavy metals through the development of plants and processes of sorption and desorption in clays, in areas of landfill, already infected, as in Coelho et al (2016), Salam et al (2016) and Rong et al (2017).…”

The organic carbon present in the landfill leachate (LL) can improve the physical quality of the soil when applied in agricultural areas, minimizing the problem of disposal of this waste. The objective of this work was to evaluate the effect of the application of different doses of LL on the physical quality of the LATOSSOLO VERMELHO (Oxisol) after five years of applications. The treatment consisted of applications of LL in doses of 32, 65, 98 and 130 m 3 ha -1 crop -1 and the treatment that receives mineral fertilizer. The physical quality of the soil was evaluated in soil samples collected in the layers 0.00-0.10 and 0.10-0.20 m, through the analysis of stability and diameter of the aggregates, soil density, total aeration capacity, field capacity and available water content. After five years of application of LL, at doses of 65, 98 and 130 m 3 ha -1 crop -1 have promoted a linear increase of the aggregates with diameter greater than 2.00 mm, of the weighted average and geometric diameters and of the soil density, with a consequent reduction of the ratio between macro and micropores and the aeration capacity of the layers 0.00-0.10 and 0.10-0.20 m. After five years of these applications, the soils that received the dose of 32 m 3 ha -1 crop -1 presented the best physical quality in relation to the other doses, since this dose did not promote an increase of the aggregates larger than 2 mm in the superficial layer (0.00-0.10 m) and was the dose with lower effect in the reduction of aeration of the soil, in relation to the others (65, 98 and 130 m 3 ha -1 crop -1 ) in the layers 0.00-0.10 and 0.10 -0.20 m.

O objetivo do trabalho foi avaliar o efeito da aplicação de diferentes doses de LAS sobre a qualidade física de um LATOSSOLO VERMELHO Distroférrico após cinco anos de aplicações. Os tratamentos consistiram de aplicações de LAS nas doses de 32, 65, 98 e 130 m 3 ha -1 safra -1 e um tratamento que recebe fertilizante mineral. A qualidade física do solo foi avaliada em amostras de solo coletadas nas camadas 0,00-0,10 e 0,10-0,20 m, por meio da análise da estabilidade e diâmetro dos agregados, densidade do solo, capacidade de aeração total, capacidade de campo e teor de água disponível. Após cinco anos de aplicações de LAS, nas doses de 65, 98 e 130 m 3 ha -1 safra -1 promoveram aumento linear dos agregados com diâmetro maior que 2,00 mm, dos diâmetros médio ponderado e geométrico e da densidade do solo, com consequente redução da razão entre macro e microporos e da capacidade de aeração das camadas 0,00-0,10 e 0,10-0,20 m. Após cinco anos de aplicações de LAS, os solos que receberam a dose de 32 m 3 ha -1 safra -1 apresentaram a melhor qualidade física em relação às demais doses, pois, essa dose não promoveu aumento dos agregados maiores que 2 mm na cama...

“…Animal manure can improve physical properties of the soil by reducing soil bulk density and compaction, and by improving soil structure (Khaleel et al 1981;Barbosa et al 2015) through the production of stable soil aggregates (Boyle et al 1989), soil aeration, and water retention, especially in sandy soils (Hafez 1974;Schoenau and Davis 2006).…”

“…Wet aggregate stability measures the stability of soil structure; a reduction in wet aggregate stability predisposes the soil to degradation (Mbagwu 2003). Barbosa et al (2015) reported that the application of LPM improved aggregation in an oxisol. A study by Dunjana et al (2012) on the effect of solid cattle manure on soil properties showed an increase in macroaggregate stability of clay soils following 7 yr of cattle manure application.…”

Pig (Sus scrofa) manure is added to the soil to supply nutrients and improve soil properties. To our knowledge, no direct comparison has been made on the effect of liquid pig manure (LPM) and solid pig manure (SPM) on the physical properties of a prairie soil. This study was established in 2009 at the University of Manitoba's Ian Morrison Research Station in Carman, Manitoba. The treatment design was a split-plot structure with cropping system as the main plot and manure treatments as subplots. Five years after the study was initiated, soil samples were collected from the 0-10 cm and 10-20 cm depth intervals for determination of bulk density, saturated hydraulic conductivity (K sat ), and water retention at field capacity and permanent wilting point (PWP). For wet aggregate stability, samples were collected from the 0-5 cm layer. Land application of SPM significantly decreased bulk density by 14%, significantly increased K sat by 110% in the 0-10 cm layer, and resulted in a 30% increase in wet aggregate stability (P < 0.05). In perennial plots, SPM increased water retention at field capacity, PWP, and available water in the 0-10 cm compared with annual plots. This was not the case for LPM-amended soils. We conclude that SPM has the potential as an organic amendment to improve the physical properties of the topsoil.Key words: bulk density, saturated hydraulic conductivity, field capacity, available water, aggregate stability, water retention.Résumé : On ajoute les déjections du porc (Sus scrofa) au sol pour l'enrichir d'oligoéléments et en rehausser les propriétés. Pour autant que le sachent les auteurs cependant, l'effet du lisier, fraction liquide de ces déjections, et du fumier, leur fraction solide, sur les propriétés physiques du sol des prairies n'a jamais fait l'objet d'une comparaison directe. En 2009, ils ont donc entrepris une étude à la station de recherche Ian Morrison de l'Université du Manitoba, à Carman (Manitoba), afin d'y remédier. L'expérience consistait en un dispositif en tiroir avec pour principal paramètre le système de culture et pour facteur secondaire, le type d'amendement. Cinq ans après le début de l'étude, les chercheurs ont prélevé des échantillons de sol aux profondeurs de 0 à 10 cm et de 10 à 20 cm en vue de mesurer la masse volumique apparente du sol, la conductivité hydraulique au point de saturation (K sat ) ainsi que la capacité au champ et le point de flétrissement permanent (PFP). Des échantillons ont aussi été prélevés dans les cinq premiers centimètres de sol pour établir la stabilité des agrégats humides. L'application de fumier au sol diminue de façon significative la masse volumique apparente (de 14 %), augmente significativement K sat (de 110 % dans les dix premiers centimètres) et accroît la stabilité des agrégats humides de 30 % (P < 0,05). Dans les parcelles de vivaces, le fumier améliore la quantité d'eau retenue à la capacité au champ, le PFP et le volume d'eau disponible dans la couche de 0 à 10 cm, comparativement à ce qu'on observe sur les parcelles de ...
