“…At the dose of 6.222 Mg ha -1 , Zn contents reached 10.13 mg dm -3 , with increment of 41.75% in relation to the manure dose of 1.037 Mg ha -1 . These results corroborate those reported by Scherer & Nesi (2009) Table 2). The increase in pH in H 2 O is due to the higher amount of poultry manure applied on surface, which is related to greater release of cations and mineralization of soil organic matter by microorganisms, transforming it into organic substances (organic and humic acids), which attract cations, as well as the release of NH 4 + , which can have an initial alkaline effect.…”

“…Similar results were obtained by Rós et al (2013), Scherer & Nesi (2009) and Andreola et al (2000), with the use of poultry manure. These results corroborate those of Moreti et al (2007), who observed that, in the layer of 0.0-0.1 m, Ca contents were higher when using poultry manure and poultry manure + half of the mineral fertilization, attributing it to the higher content of organic matter in the poultry manure, which promotes lower leaching of cations.…”

“…According to Scherer & Nesi (2009), soil tillage system and fertilizer source influence the availability and distribution of nutrients in the soil profile. In area with recovered pasture, Moreira et al (2005) observed higher values of pH, Ca +2 , Mg +2 , P, K + , Zn, organic matter, macroporosity and total porosity, and lower values of soil density and resistance to penetration.…”

A B S T R A C TPoultry manure and mechanical management may influence the distribution of nutrients in the soil profile. The objective was to evaluate physical and chemical changes in a soil with palisade grass (Brachiaria brizantha cv. Marandu) fertilized with doses of poultry manure with and without use of soil chiseling, after 180 days of application. The design was a randomized blocks with four replicates, in a 5 x 2 factorial arrangement with five doses of manure (0, 1.073, 2.074, 4.148 and 6.222 Mg ha -1 ), with and without soil chiseling at 0.20 m. Soil chiseling caused physical changes with an increase of macroporosity in the layer of 0-0.2 m and reduction in soil density and increase in macroporosity and total porosity in the layer of 0.2-0.4 m. With manure doses, pH in the layer of 0-0.1 m showed quadratic fit with maximum value of 7.2. The increases in Ca and Zn in the layer of 0-0.1 m were, respectively, 0.61 cmol c dm -3 and 2.99 mg dm -3 . In the interaction of Dose x Management, without soil chiseling, K showed a linear fit and increased 1.39 times; while in the interaction of Dose x Management, with soil chiseling in the layers of 0.1-0.2 and 0.2-0.4 m, P increased by 8.10 and 3.95 mg dm -3 , respectively. In the contrast between the dose zero and manure dose, there was significance for pH, Ca, P and Zn in the layer of 0-0.1 m.Alterações físicas e químicas em solo fertilizado com esterco de galinha em diferentes manejos R E S U M O O esterco de galinha e o manejo mecânico podem influenciar na distribuição de nutrientes no perfil do solo. O objetivo foi avaliar as alterações físicas e químicas no solo com capim Marandu fertilizado com doses de esterco de galinha sem e com uso de escarificador, após 180 dias de aplicação. O delineamento foi em blocos ao acaso com quatro repetições num arranjo fatorial 5 x 2, com cinco doses de esterco (0, 1,037; 2,074; 4,148; 6,222 Mg ha -1 ) sem e com escarificação a 0,20 m. A escarificação favoreceu alterações físicas com aumento de macroporosidade na camada 0-0,2 m e redução de densidade do solo e aumento de macroporosidade e porosidade total na camada 0,2-0,4 m. Com doses de esterco o pH na camada 0-0,1 m teve ajuste quadrático com valor máximo de 7,2. O aumento nos teores de Ca e Zn na camada 0-0,1 m foi, respectivamente, de 0,61 cmol c dm -3 e de 2,99 mg dm -3 . Na interação dose x manejo sem escarificação do solo o K teve ajuste linear com aumento de 1,39 vezes enquanto na interação entre dose x manejo com escarificação nas camadas 0,1-0,2 e 0,2-0,4 m, o P teve aumento de 8,10 e 3,95 mg dm -3 , respectivamente. No contraste entre dose zero com dose de esterco houve significância para pH, Ca, P e Zn na camada 0-0,1 m.

“…These results corroborate those obtained by SCHERER & NESI (2009), which showed that the addition of poultry manure and/or pork increased Cu 2+ and Zn 2+ content in the surface layer (0-20 cm) soil, especially in direct planting system. The authors emphasized the effect of manure in Cu 2+ and Zn 2+ soil contents, regardless of tillage system, restricted to the first 20 cm.…”

Association of swine wastewater and mineral fertilization on black oat production

et al. 2016

Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The objective of this study was to evaluate the soil chemical properties and the leachate in face of the association of swine wastewater and mineral fertilization (MF) in oat cultivation. An experiment in drainage lysimeter was carried out, using SW applications associated to MF or not, where treatments consisted of doses of 0, 100, 200 and 300 m 3 ha -1 with the absence or presence of MF, under field conditions. We concluded that swine wastewater provided significant increases in sodium, copper, zinc, and nitrite + nitrate as well as pH and calcium reductions in the soil; and in the leachate, significant increase in sodium. Moreover, the use of mineral fertilizer comprising nitrogen, phosphorus and potassium induced a significant increase in phosphorus, potassium and electrical conductivity and a significant reduction in magnesium in the soil; however, in the leachate, electrical conductivity was increased.
