“…These results corroborate those of Moreti et al (2007), who observed difference of 78.25 mg dm -3 between poultry manure dose and control. In the layer of 0.1-0.2 m, the contrast was significant with interaction of Dose x Management with soil chiseling for the poultry manure doses of 4.148 and 6.222 Mg ha -1 , and estimates of -7.07 and -8.67 mg dm -3 .…”

“…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.…”

“…The maximum dose tested (6.222 Mg ha -1 ) promoted value of 5.91, i.e., 6.77% higher compared with 1.037 Mg ha -1 of poultry manure. For Moreti et al (2007), with the application of poultry manure in typic dystrophic Red Latosol with clayey texture (LVd), pH (CaCl 2 ) was equal to 5.3 in the layer of 0.1-0.2 m. Similar results were observed by Silva Neto et al (2013), who attributed lower pH values in the deeper layers to the physical characteristic of the residue and intrinsic characteristics of the soil, which may have leached ammoniacal nitrogen to these layers and intensified the process of nitrification.…”

“…In sustainable agriculture, various fertilization systems with mechanical management can be adopted in order to maintain soil fertility (Moreti et al, 2007). The use of chiseling implements in pastures with soil physical and chemical problems may promote dual benefits; first, breaking compacted surface layers and second, incorporating poultry manure (Brasil, 2009).…”

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.

“…For a sustainable agriculture, many management systems with mechanical fertilization can be studied aiming to maintain soil fertility (Moreti et al, 2007). The use of chisel plows in degraded pasture areas can break the compacted superficial layer of the soil and, in a certain way, incorporate poultry manure in the pasture, according to the recommendations of Brasil (2009).…”

The objective of this study was to evaluate the productive and chemical characteristics of Marandu grass fertilized with poultry manure with or without the use of soil chiseling, during a period of 210 days. The experiment was conducted in a Dark-Red Latosol (Haplustox) of sandy texture, in a randomized block design with 4 replicates, in a 6 x 2 factorial scheme (0, 1.037, 2.074, 4.148, 6.222 t ha-1 of poultry manure and an additional treatment with chemical fertilizer based on 2.074 t ha-1, with and without soil chiseling). Grass-cutting management was performed between 95% of light interception by the canopy and the residual height of 0.15 m. The application of poultry manure resulted in an increase of forage production with higher number of cuts (NC). A linear model described the effect of the applied manure doses on dry matter accumulation (DMA), stems + sheaths (SS) and dead material (DM). There was significant interaction between manure doses and soil managements for leaf blade (LB), with greater variations in the treatment without soil chiseling. For plant chemical evaluation, a negative effect of poultry manure was observed on the contents of Ca, Mg, N, S, Mn and Zn, which may be due to the increased number of cuts. Poultry manure positively changed the production of Marandu grass.

BackgroundSoil quality (SQ) assessment is affected by methods that convert data sets into indices, and such analyses are expensive and time‐consuming. Qualitative SQ assessments are faster and cheaper than quantitative methods, and they can be repeated to monitor SQ in crop and pasture systems. We evaluated SQ using qualitative and quantitative SQ indicators of two grazing systems under Voisin Rational Grazing (VRG) with trees (WT) or without trees (NT). We took an adjacent native forest as a reference, and we used principal component analysis (PCA) to compare the accuracy of the assessment methods.ResultsAccording to the set of indicators used for quantitative assessment, the WT system and the Forest had higher SQ than other systems, due to higher values of soil physical and chemical indicators. That reflected better performance of soil in functions related to structural support, nutrient cycling, and biological productivity. According to the set of indicators used for qualitative assessment, the WT system showed better SQ than the areas NT, due to the higher scores of all indicators and better performance of the soil functions, and those values were close to the Forest in the indicators. PCA applied to integrate the data of qualitative and quantitative indicators indicated that SQ in WT was similar to the Forest.ConclusionsThe qualitative evaluation was as efficient as the quantitative evaluation for SQ assessment in VRG areas with and without trees. Its use can promote farmers’ autonomy and the development of skills to identify environmental factors that help to evaluate their practices.This article is protected by copyright.
