“…The PS doses were different between the years as a consequence of the N content in the manure, which changed in each period of application (Table 1). Positive and linear response to PS has been reported for natural pastures (Scheffer-Basso et al, 2008), Tifton 85 (Vielmo et al, 2011) and giant missionary grass (A. jesuiticus x A. scoparius) (Miranda et al, 2012). These reports and our results indicate 150 m 3 PS ha -1 (499 kg N ha -1 ) did not differ from the DMY obtained with ammonium sulfate (60 kg N ha -1 ).…”

A B S T R A C TThis study evaluated the response of carpet grass to pig slurry fertilization in order to estimate the agronomic efficiency and the plant-available nitrogen (N) of such manure. A field test was conducted during two years, following a randomized block design with six replicates of the treatments: 0, 100, 200, 300, 400 and 500 kg N ha ). The average agronomic efficiency of the manurewas 15 kg DM kg -1 N and it was lower than that found with ammonium nitrate (27 kg DM kg -1 N).The estimated plant-available N of the pig slurry was similar between the growing years. The N fraction of this manure available to the pasture was 0.64 (2008-09) and 0.60 (2009-10).Dejeto líquido de suínos em pastagem de grama-tapete: Produção e nitrogênio disponibilizado R E S U M O Este estudo avaliou a resposta da grama-tapete à aplicação de dejeto líquido de suíno para determinar a eficiência agronômica e estimar a disponibilidade de nitrogênio desse esterco.

-This study assessed the effect of successive applications of pig slurry on the dry matter (DM) production and the nitrogen use efficiency of giant missionary grass along two years. A total of 55, 110, 165, 220 and 275 m 3 of pig slurry/ha/year were applied in order to supply 100, 200, 300, 400 and 500 kg of total N/ha/year, respectively. These treatments were compared with the ammonium nitrate (200 kg of N/ha/year) source of N and with a control (no nitrogen application).Annually, nitrogen was applied in four divided doses, after the cutting of forage grasses, which takes place five times a year.The total DM yield did not differ between years and increased linearly as a function of pig slurry application, ranging from 2,698 kg of DM/ha/year (control) to 11,371 kg of DM/ha/year (275 m The efficiency index of pig slurry ranged from 0.52 to 0.72.

“…GATIBONI et al (2008) reported that when the levels of available P in soil reach the "very high" group, the risks of environmental contamination are high. To evaluate the response of a pasture to the application of pig slurry, SCHEFFER-BASSO et al (2008) found a significant increase of P in the plots that received manure application. CERETTA et al (2003) also showed high concentration of P in the topsoil, with increases of 580% at 8.3 months and 6,710% after 48 months of application of liquid swine manure.…”

ABSTRACT:The objective of this study was to evaluate the effects of the nitrogen fertilization in the form of swine deep bed in the properties of a quartz-sand neosol. The organic compound used was the deep bed made with rice hulls, from a commercial swine finishing system farm. Deep bed samples have been collected at various points in the installation in order to obtain a representative composite sample which has been fractionated in a 2.0 mm sieve and submitted to a 50-day maturation period. Then, agronomic value analyses were done. The experimental design was completely randomized. The treatments consisted of 0; 75; 150 and 300 mg dm -3 of N doses of deep bed as well as an additional treatment with ammonium sulfate at a 150 mg dm -3 of N. The experimental period in the greenhouse was 45 days, where the soil was cultivated with maize. After the experiment completion, further soil properties analyses were done. From the results, it was noted that the organic fertilization with deep bed provided a significant increase in the levels of potassium, in the sum of the bases, in the effective CEC, in the CEC at pH 7.0 and in the percentage of saturation.KEYWORDS: swine production, swine buildings, alternative management, waste treatment, organic fertilizer, quartz-sand neosol. ADUBAÇÃO NITROGENADA NA FORMA DE CAMA SOBREPOSTA DE SUÍNO E SEUS EFEITOS NOS ATRIBUTOS DE UM NEOSSOLO QUARTZARÊNICO1 RESUMO: Objetivou-se com o presente trabalho avaliar os efeitos da adubação nitrogenada na forma de cama sobreposta de suíno sobre os atributos de um Neossolo Quartzarênico. O composto orgânico utilizado foi a cama sobreposta, feita com casca-de-arroz, proveniente de uma granja comercial de suínos em sistema de terminação. As amostras de cama sobreposta foram retiradas em vários pontos da instalação, visando a obter-se amostra composta representativa, após o que foi fracionada em peneira de 2,0 mm e submetida a uma compostagem adicional de 50 dias. Na sequência, foram realizadas análises de valor agronômico. O delineamento experimental foi o inteiramente casualizado. Os tratamentos constituíram-se das dosagens de 0; 75; 150 e 300 mg dm -3de N na forma de cama sobreposta, bem como um tratamento adicional com sulfato de amônio na dose de 150 mg dm -3 de N. O período experimental em casa de vegetação foi de 45 dias, onde se cultivou o solo com milho. Finalizado o experimento, procedeu-se a nova análise dos atributos do solo. Pelos resultados obtidos, notou-se que a adubação orgânica com cama sobreposta proporcionou aumentos significativos nos teores de potássio, na soma de bases, na CTC efetiva, na CTC a pH 7,0 e na porcentagem de saturação por bases.
