“…The −Legume pastures exhibited significantly increased microbial PLFA abundance, SOC, TN, and SOM in response to +Compost treatments, but no significant differences between +Compost and −Compost treatments were observed in +Legume pastures (Table 2, Figures 1b,3b,and 4b). Although some studies have shown impacts of compost on legume production (Hentz, Scheffer-Basso, Escosteguy, & Fontaneli, 2008), we observed no consistent effects of compost addition on forage biomass collected during each summer sampling event (data not shown) that would explain our results. We were able to estimate plant biomass and composition in 1-m −2 subplots at each summer soil sampling date during early season plant growth, but not in the fall because of hay cutting immediately preceding each fall sampling date.…”

Establishment of improved perennial pasture systems for livestock production has been demonstrated to improve soil health in the semiarid Texas Southern High Plains (SHP). Use of waste products from other components of the animal production chain, such as applying composted manure from feedlot operations to grazed pastures, may provide an additional means of improving soil health and sustainability of these systems. However, few studies have examined the impact of composted animal manure on the changes in soil microbial communities, although they are important indicators of soil health. We investigated the effects of a one-time composted cattle manure application at 3.36 Mg ha −1 on soil microbial community size and structure, soil organic C (SOC), total N (TN), and soil organic matter (SOM) up to 1.5 yr after application. We compared pastures consisting of either WW-B. Dahl Old World bluestem grass [Bothriochloa bladhii (Retz.) S.T. Blake] alone or in mix with alfalfa (Medicago sativa L.). Results showed that compost application significantly increased SOC by about 4.4 g kg −1 soil within 1.5 yr after application. In N-fertilized grass-only pastures, compost addition increased microbial phospholipid fatty acid abundance, SOC, TN, and SOM, but no significant differences were observed between compost treatments in unfertilized pastures containing legumes. Our results show that even a one-time compost addition at a relatively low rate can augment SOC in this semiarid pasture system after 1.5 yr, and that stimulation of soil microbial abundance and soil C and N from compost is more pronounced in fertilized grass-only pastures compared with those with legume establishment.

“…Organic fertilizers contain highly variable concentrations and rates of nutrient release in the soil, and for pig deep-litter (PDL) there are still no indices of availability (IA) of the main nutrients, such as nitrogen, phosphorus and potassium (Hentz et al, 2008). As the PDL system is recent, little is known about the quantities to be used in crops, exclusively or associated with NPK fertilization.…”

The use of pig deep-litter (PDL) in pasture fertilization can be an important alternative from an environmental and economic point of view. This study was conducted to evaluate the fertilization with PDL exclusively or in association with mineral fertilizers on the quality and productivity of Panicum maximum cv. Mombasa. The experiment was carried out in Ipameri, GO, Brazil. The design was a randomized block design in a 2 x 5 factorial scheme with four repetitions, in plots of 24 m². The doses of PDL (0; 5; 10; 15 and 20 Mg ha-1) were tested, with or without fertilization with NPK (50 kg ha-1 of P2O5, 10 kg ha-1 of K2O and 10 kg ha-1 of N). The organic fertilizer was applied broadcast at the planting of the pasture, and the mineral fertilizers were split and applied at planting and as topdressing. Dry mass, crude protein, acid detergent fiber and neutral detergent fiber were evaluated. PDL doses associated with mineral fertilization led to linear increases from 52 to 282% in the analyzed variables and better bromatological composition. PDL application is beneficial to the production of pastures, and increasing applications up to the PDL dose of 20 Mg ha-1 associated with mineral fertilization promoted better quantitative and qualitative results. With exclusive fertilization with PDL, the gains in quality and productivity were more modest.

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.
