“…The nitrogen provided by the swine wastewater stimulated the forage plant growth, the tillering, the emergence of new leaves, and, consequently, the expansion of aerial part and root system (Galindo et al, 2018;Serafim & Galbiatti, 2012), evidencing how much livestock production could be increased with the use of swine wastewater. Researches with forages plants confirmed that application of swine wastewater, promotes greater plant growth in relation to the control treatment (Brustolin-Golin et al, 2016;Galindo et al, 2018;Pandolfo & Veiga, 2016).…”

The management of swine wastewater is of great importance where swine breeding is considerable and can represent an important fertilizer at maintenance of forages. The objective was to identify the Urochloa brizantha cultivar more responsive to fertilization with swine wastewater. The experimental design was in randomized blocks, with a 3 × 5 factorial scheme and four replications. The treatments consisted of three Urochloa brizantha cultivars (Marandu, Xaraés and Piatã) and five swine wastewater doses (0.0; 3.5; 7.0; 10.5 and 14.0 g dm3 pot-1). The experiment was carried out in a greenhouse in the city of Cuiabá-MT. Three cuts were performed in the aerial part of the plants with intervals of 30 days between them. The application of the swine wastewater, regardless of the cultivar provided an increment in the production of dry mass, plant height, number of tillers, number of leaves and crude protein content, besides reducing the neutral detergent fiber and acid detergent fiber contents. The swine wastewater can be used as an alternative in the fertilization of Urochloa brizantha, because the cultivars were responsive to fertilization.

“…Under these conditions, soil natural fertility, manure doses used and the crop type are factors that have great influences on the results. An example is a study by Pandolfo and Veiga [2] on a Hapludox soil, in Campos Novos, SC, with increasing doses of PS in different management systems related to the maintenance of crop residues on the soil surface. First, the authors observed that winter pasture biomass production and maize grain yield in the summer were higher after the second year of evaluation, due to the improvement of soil fertility with PS applications.…”

“…However, due to the intensive production system in the swine units, the volume of waste produced daily is high. In these conditions, the use of swine manure as fertilizer in crop and pasture areas is an established strategy, promoting a targeting use of this material and cycling of nutrients [2].…”

“…Studies carried out in these Brazilian states have shown that SM are rich sources in macro and micronutrients, and their beneficial use for plant growth and development, serving as an interesting alternative in the partial or total replacement of mineral fertilizers, promoting the maintenance of productivity and decrease in external inputs in agricultural production areas [2,5,9,10]. In addition, SM applications in agricultural areas promotes benefits to different soil properties, increasing soil fertility, improving soil structure and microbiological activity [4,6,9,11,12].…”

Soil Contamination [Working Title]

View full text Add to dashboard Cite

A major challenge in agricultural production systems is the maximization of resources used to promote the development of crops with a minimum of environmental impact. In this sense, the use of fertilizers of animal origin has great potential to promote the improvement of soil properties. In southern Brazil, swine manure (SM) is widely used in agricultural areas, allowing nutrient cycling within pig units and reducing costs for chemical fertilizers. Much of this manure is applied in liquid form (PS), but other strategies are often used, such as PS compost and swine bedding (DL). The use of these SMs improves the chemical, biological, and physical attributes of the soil, contributing to increased fertility and productivity of crops. However, prolonged use or applications with high doses of SM can result in the accumulation of metals and phosphorus in soils, representing a risk of contamination of soils and surface water resources, mainly due to losses by runoff, and subsurface, by leaching. Therefore, the adoption of criteria and the rational use of PMs need to be adopted to avoid dangerous effects on the environment, such as plant toxicity and water contamination. The potentialities and risks of SM applications are discussed in this chapter.

“…Therefore there is great concern in making the rational disposal of these residues in the environment, so that there is no compromise of soil, plants and water resources [2]. One of the causes of pasture degradation is the fertilization absence, the use of swine liquid manure as a source of nutrients is an alternative to be used [3] [4].…”

The objective was to verify the possibility of supplying the nutritional requirement of Tifton 85 grass with swine liquid manure in an intensive management system. The experiment was carried out in a randomized block design, with four treatments of swine liquid manure doses: 0, 70, 140 and 210 m 3 •ha −1 , divided into seven applications and a treatment of mineral fertilization of 200 kg of nitrogen ha −1 •year −1. Samples of the collected plant material were weighed to obtain fresh mass taken for drying and then ground for bromatological determination. The dry mass production data were obtained by dry matter accumulation during the cuts and averages were made for the variables; plant height, crude protein, NDF, ADF, neutral detergent insoluble protein (NDIP) and acid detergent insoluble protein (ADIP). The data were subjected to variance analysis, performing regression for swine liquid manure doses and averages test (Dunnett test) to compare the doses with the mineral fertilization. Higher plant heights, dry mass production, crude protein content, neutral detergent insoluble protein content and lower neutral detergent fiber content in Tifton 85 grass were observed with mineral fertilization. In the variables, acid detergent fiber and acid detergent insoluble protein there was no difference (P = 0.05) between the mineral fertilization and the swine liquid manure doses. There was a linear increase (P = 0.05) of swine liquid manure doses only in dry matter production. Swine liquid manure doses up to 210 m 3 •ha −1 •year −1 do not meet the entire nutritional requirement of Tifton 85 grass, recommending the evaluation of higher swine liquid manure doses or complementation with mineral fertilization.
