“…Despite the superiority of mineral fertilization, there was a residual effect of application of compost from one crop to the next. Adami et al (2012), in a study on fertilization with poultry litter, also found a residual effect on yield of black oat in succession with corn.…”

ABSTRACT:Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigation was to evaluate the effects of this compost on soil fertility and on the nutritional status and yield of the corn crop. The experiment was conducted in a Haplic Luvisol in a randomized block design with six treatments and five application rates of the organic compound in Mg ha -1 : 3 (half the standard rate), 6 (standard rate), 9 (one and a half times the standard rate), 12 (twice the standard rate), and 24 (four times the standard rate) and an additional treatment with mineral fertilizers (110, 50 e 30 kg ha -1 of N, P 2 O 5 and K 2 O, respectively), with four blocks. Evaluations were performed for two harvests of rainfed crops, measuring soil fertility, nutritional status, and grain yield. The compost increased P, K, Na and Zn values in the 0.00-0.20 m layer in relation of mineral fertilization in 616, 21, 114 and 90 % with rate 24 Mg ha -1 in second crop. Leaf N, Mg, and S contents, relative chlorophyll content, and the productivity of corn kernels increased in 27, 32, 36, 20 e 85 %, respectively, of low rate (3 Mg ha -1 ) to high rate (24 Mg ha -1 ) with of application of the compost. Corn yield was higher with application of organic compost in rate of 24 Mg ha -1 than mineral fertilizer combination in second crop.

“…We found no studies on the effects of associating poultry litter and Arad phosphate fertilizer over growth response and production of tropical forage grasses such as Urochloa brizantha and Panicum maximum. However, the positive effects of poultry litter on corn (Zea mays) and soybean (Glycine max) yields, as well as the effect of Arad phosphate on dry-matter production, have already been described (Adami et al, 2012;Orrico Júnior et al, 2013;Ragagnin et al, 2013). In this context, we tested the hypothesis that Arad phosphate fertilization associated with poultry litter would favor tropical forage grasses production and development, as well as P concentration in diagnostic leaves.…”

The interaction of natural reactive phosphate with poultry litter may increase the production of forage grasses as a result of phosphorus (P) uptake. This study's goal was to analyze growth, production and P concentration of diagnostic leaves of forage grasses fertilized by an Arad reactive phosphate + poultry litter association. The experiment employed a 2 3 factorial, with the following factors: forage grasses (Urochloa brizantha and Panicum maximum), Arad rates (0 and 50 mg dm-3 P 2 O 5), and poultry litter (0 and 7.5 g dm-3). At the first harvest, the highest dry-matter production of leaves, sheaths + stems and shoots occurred in the interaction P. maximum × Arad × poultry litter. P concentrations in diagnostic leaves as well as number of leaves were similar between forage grasses, but higher in the interaction between Arad + poultry litter when compared to isolated fertilizers. At the second harvest, dry-matter production of shoots and sheaths + stems was higher in the U. brizantha + poultry litter interaction than in other interactions. Compared to the other fertilizers, P concentration in the diagnostic leaves at second harvest was higher in grasses fertilized with poultry litter. At second harvest, the number of leaves and tillers was highest in the U. brizantha + Arad + poultry litter interaction, followed by the Arad + poultry litter interaction. The association of Arad and poultry litter promotes adequate P nutrition and biomass production of forage grasses, and can therefore be considered an important instrument for the establishment of these grasses.

“…Além disso, a utilização racional de resíduos animais como fertilizantes agrí-colas, em substituição aos adubos minerais, contribui para a redução do uso das reservas finitas de minerais e de energia não renovável (Lana et al, 2010). Embora a cama aviária seja uma das melhores fontes de fertilizante orgânico disponível (Adami et al, 2012), a utilização de doses excessivas tende a ocasionar impactos ambientais negativos (Fogel et al, 2013), como a contaminação do lençol freático por nitrato e fósforo lixiviados, bem como a eutrofização em águas superficiais (Oviedo-Rondón, 2008).…”

RESUMO -A cama aviária é rica em nutrientes, sobretudo em N, comparativamente a fertilizantes de origem orgânica comumente utilizados na agricultura. Além disso, os baixos custos e a alta oferta de cama aviária em várias regiões têm levado ao desenvolvimento de estudos para o seu aproveitamento como fertilizante. Objetivou-se avaliar o efeito da aplicação de doses de cama aviária, em cobertura, na produção de milho e na qualidade da silagem. O delineamento experimental foi de blocos casualizados, com seis tratamentos (0,0, 1,5; 3,0; 4,5; 6,0 e 7,5 t ha -1 de cama aviária curtida) e quatro repetições. Determinaram-se altura de planta e de espiga, diâmetro do colmo, prolificidade, peso de espiga, proporção de espigas na matéria verde, produtividade de matéria verde e seca de plantas. Após 65 dias de armazenamento, os silos foram abertos para determinação dos teores de matéria seca e de proteína bruta, perdas por gases e efluente, e perda total de matéria seca das silagens. As doses de cama aviária não afetaram as características agronômicas e avaliativas da silagem, exceto a produtividade de matéria verde e seca de plantas que responderam linearmente ao aumento das doses aplicadas. O maior incremento na produtividade de matéria verde e seca de plantas de milho ocorreu com a dose 7,5 t ha -1 de cama aviária, superando em 39,49% e 27,62%, respectivamente, o tratamento controle. A adubação orgânica com cama aviária não afetou a qualidade das silagens produzidas. Palavras-chave: adubação, resíduo orgânico, produtividade, parâmetros qualitativos, Zea mays L. USE OF POULTRY MANURE IN CORN YIELD AND SILAGE QUALITYABSTRACT -Poultry manure is rich in nutrients, especially N, as compared with manure commonly used in agriculture. Moreover, the low costs of organic fertilizers compared with chemical fertilizers, the high offer of poultry manure in various regions has led to the development of studies for its use as fertilizer. The objective of this study was to evaluate the effect of doses of poultry litter, in coverage, in corn silage yield and silage quality. The experiment consisted of a randomized block design with six treatments (0.0, 1.5, 3.0, 4.5, 6.0 and 7.5 t ha -1 of tanned poultry litter) and four replications. The height of plant and ear, stem diameter, prolificacy, the ear weight, the proportion of ears in green matter, the productivity of green and dry matter of plants were determined. After 65 days of storage, the silos were opened to determine the dry biomass, crude protein, losses by gases and by effluent and loss total of dry biomass of silages. The poultry litter did not affect the agronomic characteristics and quality of silage, except the productivity of green and dry matter of plants that responded linearly to the increase of the doses applied. The highest increase in the productivity of green and dry matter of corn plants occurred with the 7.5 t ha -1 of poultry litter exceeding by 39.49% and 27.62%, respectively, the control treatment. The organic fertilization with poultry manure does not affect quali...
