ABSTRACT Swine wastewater can be used as a biofertilizer and promote significant improvements in soil physical-chemical attributes and yield. The objective of this study was to evaluate the effects of swine wastewater application on soil and maize yield. The experiment was conducted at the Agricultural Sciences Center of the Federal University of Piauí, in Teresina, Piauí, Brazil, from August to November 2015. The experimental design used completely randomized blocks in split-plot scheme, with five doses of swine wastewater (0, 25, 50, 75 and 100 m3 ha-1) in the plots and two soil depths (0.20 and 0.40 m) in the subplots, with four replications. Exchangeable contents of calcium, magnesium, phosphorus, potassium and sodium, electrical conductivity, pH, sum of bases, base saturation, potential acidity and cation exchange capacity, and crop yield were evaluated. Results showed calcium, magnesium, sum of bases and cation exchange capacity increased with elevated levels of swine wastewater. Potassium and sodium contents however decreased with doses of 51.58 and 52.28 m3 ha-1, respectively. Except for potassium and potential acidity, variables showed higher values at the 0-0.20 m depth.

The corelations between White Rot (Rigidoporus lignosus L.) incidence and  soil characters of rubber ecosystem in Penumangan Baru, Lampung. A study was conducted to evaluate the corelation between soil characters and white rot incidence. The study was done in Penumangan Lampung from June 2007 to July 2008. Seven sites were observed on the incidence of white rot of indicator plants (cassava). Physical, chemical, and biological soil characters were correlated and regressed with white rot incidence. The results showed that there were correlation between white rot incidence and soil characters such as pH KCl, number of fungal genus (fungal diversity), Ca+, total cation, CEC, and saturation base. Ion Ca+, total cation, saturation base correlated positively with white rot incidence, on the contrary, fungal diversity, cation exchange capacity, and pH KCl correlated negatively with white rot incidence. Thus, efforts to increase fungal diversity, cation exchange capacity, and pH (in acidic soil) could be used as basic strategies to develope intergrated  control of white rot disease.

Soils with small variations in relief and under the same management system present differentiated spatial variabilities of their attributes. This variability is a function of soil position in the landscape, even if the relief has little expression. The aim of this work was to investigate the effects of relief shape and depth on spatial variability of soil chemical attributes in a Typic Hapludox cultivated with sugar cane at two landscape compartments. Soil samples were collected in the intercrossing points of a grid, in the traffic line, at 0-0.2 m and 0.6-0.8 m depths, comprising a set of 100 georeferenced points. The spatial variabilities of pH, P, K, Ca, Mg, cation exchange capacity and base saturation were quantified. Small relief shape variations lead to differentiated variability in soil chemical attributes as indicated by the dependence on pedoform found for chemical attributes at both 0-0.2 m and 0.6-0.8 m depths. Because of the higher variability, it is advisable to collect large number of samples in areas with concave and convex shapes. Combining relief shapes and geostatistics allows the determination of areas with different spatial variability for soil chemical attributes.

SUMMARYSpatial nutrient distribution was studied under a three-and-a-half-year-old fallow of Dactyladenia barteri, Alchornea cordifolia, Senna siamea and Gmelina arborea hedgerows grown on an acid Ultisol in southeastern Nigeria. The objectives were to evaluate the nutrient cycling capacity and suitability of the hedgerow species for alley cropping. No consistent patterns were observed in the lateral distribution of soil pH, total nitrogen, organic carbon, available phosphorus, exchangeable cations (potassium, calcium, magnesium and sodium), total acidity and effective cation exchange capacity in the 4 m wide alleys formed between the hedgerow species. Senna siamea and Gmelina arborea tended to increase soil organic carbon, calcium, magnesium and effective cation exchange capacity, particularly in the top 50 cm, compared with Alchornea cordifolia and Dactyladenia barteri, and can therefore be recommended for soil fertility regeneration on acid Ultisols during periods of fallow. However, they appear to be less suitable for alley cropping than Dactyladenia barteri because they are shallow rooting.Propiedades químicas delo suelo bajo cuatro especies de seto vivo

Global demands for an increased food production have prompted scientists to create technological innovations in various segments of the agricultural and environmental sectors. The use of diffuse reflectance spectroscopy in soil color determination to estimate its attributes is an example of these advances. Thus, the aim of this research was to identify the potential of the three parameters of the Munsell color system (Hue, Value, and Chroma) in estimating different chemical and particle size attributes by pedotransfer functions in a Typic Hapludox in the Cerrado of Piauí State, Brazil. This soil showed a yellowish color due to the goethite and low contents of bases and organic carbon. Among the calibrated pedotransfer functions, we observed that phosphorus, aluminum, hydrogen, potential acidity, potential cation exchange capacity, and base saturation could be estimated by Hue, while clay content by Value, and Chroma used to estimate hydrogen, potential acidity, and cation exchange capacity. We conclude that the parameter color could be used to estimate soil attributes.

The aimed of this study was to evaluate the effects of different dosages of turkey litter on soil’s chemical attributes and yield of the Urochloa decumbens in classified as degraded pasture. The work was performed at the municipality of Mineiros-GO between October/2011 and September/2013 in Quartzipsamment soil. The treatments consisted in applications of 0, 3, 6, 9 and 12 Mg ha-1 of turkey litter at a randomized-complete blocks design with four replications. Was evaluated the fodder’s productivity and the following soil’s chemical attributes: organic matter, hydrogenionic potential (CaCl2), phosphorus (resin), potassium, calcium, magnesium, cation exchange capacity and base saturation of soil. In general terms, the increase of turkey litter’s doses increased the grass productivity and the supply of nutrients of the soil, maintaining the balance of the soil-plant system. The dosage of 12 Mg ha-1 year-1 of turkey litter ensure higher amounts in the soil’s chemical attributes and in the productivity of dry mass of Urochloa decumbens.

The number of studies on the importance of Cerrado soil to biogeochemical cycles is growing, with this being the focus of most research in the Cerrado biome. The objective of this research was to verify the correlation among different chemical attributes of the soil in a Cerrado fragment located in Mãe Bonifácia Park, in Cuiabá, Mato Grosso (MT), Brazil, using principal components analysis. For this study, five soil samples were collected at 0-10 cm depth monthly from August 2015 to July 2016. After the collection and identification of the soil, chemical analyses were performed to determine the following chemical characteristics of the soil: organic matter (OM), base saturation (V%), sum of bases (SB), cation exchange capacity (CTC), pH, and concentrations of H+, Al3+, Ca2+, Mg2+, K+, P, S, Cu, Mn2+, Mg2+, Zn, Fe2+ and B3+. The soil was characterized as acidic, which is typical for Cerrado soils, although some chemical elements were found in high concentrations. After the analysis of principal components, it was possible to reduce the seventeen original variables to four principal components that represented 88.86% of the total variation of the data. In which the first main component explained 41.18%, the second component explained 28.39%, the third 11.29% and the fourth explained 7.98%. Based on this analysis, it was identified that the chemical attributes such as the sum of base (SB), organic matter (OM), cation exchange capacity (CTC), calcium (Ca2+), saturation (V%) and pH represented the greater data variance.

ABSTRACT: Remineralizers are comminuted rocks that are applied to soil, and their use as an agricultural amendment was regulated in Brazil in 2013. However, mechanisms of action of these materials must be better known to enable them to be best used in agricultural fields. Soil chemical attributes of an Oxisol were monitored after the application of a diabase remineralizer. The increase in exchangeable Na observed was associated with the dissolution of the border of the plagioclase crystals where this element is highly concentrated (albite). Therefore, it was inferred that the time since the application of the remineralizer (1 to 2 years depending on the treatment) was not sufficient to exhaust this crystal volume. Unfortunately, the presence of several sources of Ca-containing minerals in the remineralizer did not allow to infer if the calcic nuclei was dissolving. An increase in effective cation exchange capacity was observed without the concurrent increase in the pH of the soil. The two non-exclusive hypotheses proposed to explain this result were that an extra surface charge has originated on the surface of the newly precipitated oxidic phases and/or from the dissolution of the remineralizer grains. Rapid precipitation of amorphous solids (as measured by the increase in Alo and Feo) would also explain the lack of increase in exchangeable Fe and Al despite the large amount of Al2O3 (11.90%) and Fe2O3 (14.45%) in the remineralizer.

The differential in the adsorption capacity of 2-chloro-4-(ethylamino)-6- (isopropylamino)-s-triazine (Atrazine) and 3-tert.-butyl-5-chloro-6-methyl- uracil (Terbacil) by 34 Puerto Rican soils was studied in the laboratory using C14-labeled herbicides. The various soils differed greatly in their capacity to adsorb Atrazine and Terbacil. The Caño Tiburones soil was found to be the most adsorptive for both herbicides; the Toa sandy loam and Talante sandy loam the least for Atrazine and Terbacil, respectively. Atrazine was consistently adsorbed to a greater degree than Terbacil. Adsorption of Atrazine was correlated positively with organic matter content, cation exchange capacity and magnesium and silt content but negatively with sand content. Adsorption of Terbacil was positively correlated with organic matter, cation exchange capacity, soil pH, content of phosphorus, calcium, magnesium and clay but negatively with sand content of the soil. Representative adsorption isotherms of Atrazine and Terbacil on several important island soils devoted to sugarcane cultivation are also presented in this report.

ABSTRACT The low soil fertility associated with the lack of adequate irrigation management are factors that most limit crop production. Therefore, the study aimed to evaluate the chemical attributes of an Oxisol and the yield of ‘Paluma’ guava under irrigation with saline water and fertilized with phosphorus, cattle manure, and boron. The treatments were distributed in randomized blocks, with four repetitions and two plants per plot, including borders on the sides of the useful experimental area, arranged in a factorial scheme (5 × 2) + 1, referring to five phosphorus doses (0, 0.08, 0.16, 0.24 and 0.32 kg of P2O5 plant-1), two doses of cattle manure, 0 and 30 kg per plant and an additional treatment consisting of 0.16 kg of P2O5 plus 30 kg of cattle manure and 1.0 g of boron, using as source the borax. In the soil, pH, phosphorus, potassium, calcium, magnesium, and the cation exchange capacity were evaluated in the 0-20 cm and 20-40 cm layers. In plants, the average yield per hectare in two harvests was estimated. The pH decreased with phosphorus doses without cattle manure and in the treatment with boron in the 20-40 cm layer. The cation exchange capacity increased with the application of phosphorus doses associated with manure and decreased in both soil layers with boron. The macronutrients evaluated were not influenced by boron. Phosphorus doses associated with cattle manure increased yield, exceeding the average of 50 t ha-1 year-1 determined for ‘Paluma’ guava. In contrast, boron did not increased the yield.
