“…These authors observed an increase in the canopy height with increasing slurry doses. Araújo et al (2011) reported an increase in canopy height with increasing doses of (non-treated) bovine liquid waste. A positive effect on Marandu grass canopy height was also observed by Santos et al (2009) using mineral nitrogen fertilizers.…”

The objective of this study was to evaluate forage production and root accumulation in Brachiaria decumbens cv. Basilisk with swine wastewater as a fertilizer. The experiment was conducted into a greenhouse in Federal Institute of Education, Science and Technology of Southeast of Minas Gerais, Rio Pomba Campus. Pots with 6 dm -3 volumes were used as experimental units. Were used a randomized block design with four replications. Were studied four swine waste doses (0, 225, 450 and 675mL pot -1 ) over four regrowth cycles. The dry matter production of the aerial part, forage accumulation rate, crude protein and dry matter production of roots increased with the highest swine waste doses being around 670, 742, 160 and 465% respectively from lower to higher dose. There was interaction between swine waste and regrowth cycles for plant height and tillering, and in all regrowth cycles responded positively with increasing swine waste doses. Applying swine waste on pastures is therefore a viable alternative to increase productivity of B. decumbens cv. Basilisk, it recommends the use of swine waste corresponding to the dose of 675mL pot -1 to maintenance pastures. Key words: Brachiaria. Effluents. Fertigation. Forage yield. ResumoObjetivou-se com este trabalho avaliar a produção de forragem e acúmulo de raízes em Brachiaria decumbens cv. Basilisk com o uso da água residuária de suínos como fertilizante. O experimento foi conduzido em casa de vegetação no Instituto Federal de Educação, Ciência e Tecnologia do Sudeste de Minas Gerais, Campus Rio Pomba. Vasos com volume de 6 dm -3 foram utilizados como unidades experimentais, utilizou-se o delineamento em blocos casualizados com quatro repetições. Foram estudadas quatro doses de água residuária (0, 225, 450 e 675 mL vaso -1 ) durante quatro ciclos de rebrotação. A produção de matéria seca da parte aérea, a taxa de acúmulo de forragem, a proteína bruta e a produção de matéria seca de raízes aumentaram com as doses de água residuária, com aumentos de cerca de 670, 742, 160 e 465% respectivamente da menor para a maior dose. Houve interação entre doses de água residuária e ciclos de rebrotação para as variáveis, altura das plantas e densidade populacional de perfilhos, sendo que em todos os ciclos de rebrotação, responderam positivamente com o aumento das doses de água residuária. A aplicação de água residuária suína é uma alternativa viável para aumento da produtividade da B. decumbens cv. Basilisk, recomenda-se o uso de água residuária correspondente à dose de 675 mL vaso -1 na manutenção das pastagens. Palavras-chave: Brachiaria. Efluentes. Fertirrigação. Produção de forragem.

“…Wastewater, such as from meat (Araujo et al, 2011) and dairy products (Santos et al, 2014) and domestic sewage sludge (Barbosa et al, 2007) have been effectively used as soil amendments due to their plant essential chemical composition. However, some solids residues, such as the sludge from the gelatine industry, still need to be evaluated as a source of plant nutrients.…”

Various types of industrial wastes have been tested as a source of pasture fertilization. However, little is known about the sludge of the gelatine industry. This study aimed at testing gelatine sludge as a soil amendment by assessing the chemical modifications caused in the soil profile. The experiment was conducted in Araguaina, Tocantins, using a typical Quartzipsamment soil (Entisols) from February to November 2013. Four doses were tested in experimental plots: 0, 50, 150 and 300 m 3 ha -1. Soil sampling was performed at four depths: 0-5, 5-10, 10-20 and 20-30 cm with collection at the beginning and the end of the experimental period. Five grazing simulations of 21 days of rest of Piatã grass were testes. The gelatine sludge was able to raise the contents of calcium, phosphorus, and sum of bases only in the superficial layer (0-5 cm) and did not alter the pH, potential acidity and saturation by base, indicating that there was no use restriction due to salinization or acidification. Therefore, it was concluded that the maximum tested dose (300 m 3 ha -1) improved the chemical characteristics of the soil, especially in the 0-5-cm layer.
