“…These authors observed corn yield increases of 30% in relation to the treatment that received standard N fertilization rate during the prior year. Reddy et al (2009), when evaluating a cotton-cotton-corn rotation system with long-term poultry litter application, also observed residual effect on corn grain yield. Corn grown after cotton on residual poultry litter without fertilization showed higher grain yields (37 and 36%) when compared to the cotton treatments that received ammonium nitrate at the same rate in 2005 and 2008, respectively.…”

“…However, when the addition of nutrients to the soil from both fertilizer sources is considered, it is possible to infer that the organic fertilizer should be recommended since it is a source of more nutrients to the soil, with a difference between the 9,907 kg ha -1 litter level and the mineral fertilizer of 19, 206 and 314 kg ha -1 of N, P 2 O 5 and K 2 O, respectively. Therefore, besides costs, it is also important to consider the benefits of nutrient addition to the soil, the release and residual effect dynamics (Nyakatawa et al, 2001;Mitchell & Tu, 2005;Reddy et al, 2009), the effects on physical, chemical and biological soil traits (Eghball et al, 2004;McGrath et al, 2010) and the environmental impact of its usage, in order to make the best decision on which source to use.…”

-The objective of this work was to assess the effect of poultry litter fertilization levels on corn and black oat yield using different grazing intensities, poultry litter levels (mixture of manure and bedding material) and a chemical fertilization level. The experimental design was a randomized complete block in a split-plot arrangement with four replicates. Black oat + ryegrass grazing intensities, characterized by different pasture sward management, with animal entrance at 25, 30 and 35-cm heights and exit at 5.0, 10 and 15-cm heights, were established at the main plots. After the grazing period, corn was grown at the subplots with four levels of poultry litter (0, 4,953, 9,907 and 14,860 kg ha -1 ), aiming to supply 0, 100, 200 and 300 kg ha -1 of nitrogen, and a treatment with chemical fertilizer, according to soil analysis. Grazing intensities had no effect on corn yield. Corn yield was 7,493, 8,458, 9,188, 10,247 and 11,028 kg ha -1 , respectively, for the treatments without and with 4,953, 9,907 and 14,860 kg ha -1 of poultry litter, and the treatment with chemical fertilization. Poultry litter levels have a residual effect on the production of black oat grown in succession to corn.Index terms: Avena strigosa, Zea mays, chemical fertilizer, organic fertilizer, residual effect, yield components. Intensidades de pastejo e níveis de adubação com cama de aviário sobre a produtividade de milho e aveia-pretaResumo -O objetivo deste trabalho foi avaliar o efeito de níveis de adubação com cama de aviário sobre a produtividade de milho e aveia-preta com uso de diferentes intensidades de pastejo, níveis de cama de aviário (mistura de esterco e material utilizado como cama) e nível de adubação química. Utilizou-se o delineamento experimental de blocos ao acaso com parcelas subdivididas e quatro repetições. As intensidades de pastejo na aveia-preta + azevém, caracterizadas por diferentes alturas de manejo do pasto, com alturas de entrada dos animais em 25, 30 e 35 cm e de saída em 5,0, 10 e 15 cm, foram impostas nas parcelas principais. Após o período de pastejo, o milho foi cultivado nas subparcelas com quatro níveis de cama de aviário (0, 4.953, 9.907 e 14.860 kg ha -1 ), para suprir 0, 100, 200 e 300 kg ha -1 de nitrogênio, e um tratamento com adubação química, conforme análise do solo. As intensidades de pastejo não afetaram a produtividade do milho. A produtividade do milho foi de 7. 493, 8.458, 9.188, 10.247 e 11.028 kg ha -1 , respectivamente, para os tratamentos sem e com 4.953, 9.907 e 14.860 kg ha -1 de cama de aviário e para o tratamento com adubação química. Há efeito residual dos níveis de cama de aviário na produtividade da aveia-preta cultivada em sucessão ao milho.Termos para indexação: Avena strigosa, Zea mays, adubação química, adubação orgânica, efeito residual, componentes de produtividade.

“…In addition, the higher CO 2 emissions in AN-SI plots can be attributed to increased biomass production in the form of crop residues from N application which directly adds C to the soil, which upon decomposition, can result in soil emission of CO 2 . Our studies comparing PL to AN sources of N on a Decatur silt loam soil have shown that inorganic N application generally results in better plant growth rate and higher biomass production compared to PL at the same application rate in the short term (Nyakatawa and Reddy 2000;Reddy et al 2009). Paustian et al (2000) also reported that N application to the soil can increase mineralization rates of soil organic matter by increasing residue input, which may also increase CO 2 emission.…”

Soil management practices can alter the natural balance at the soil-plant-atmosphere ecosystem interface, which can significantly affect the environment. This study compared CO 2 fluxes in conventional tillage (CT) and no-tillage (NT) corn ( Zea mays L.) production systems receiving poultry litter (PL) and ammonium nitrate (AN) fertilizers on a Decatur silt loam soil in the Tennessee Valley region of North Alabama from Spring 2008 to Fall 2009. Soil CO 2 flux in CT plots (9.5 kg CO 2 ha −1 day −1 ) was significantly greater than that in NT plots (4.9 kg CO 2 ha −1 day −1 in summer. Soil CO 2 fluxes were lowest in fall where CT plots had a mean soil CO 2 emission of 0.8 kg CO 2 ha −1 day −1 , while plots under NT and grass fallow system were sinks of CO 2 with fluxes −0.6 and −1.0 kg CO 2 ha −1 day −1 , respectively. Mean soil CO 2 flux averaged over seasons in NT plots was 36% lower than that in CT plots. Grass fallow plots were net sinks of CO 2 with a mean CO 2 flux of −0.4 kg CO 2 ha −1 day −1 . Our study showed that application of PL or AN fertilizer in NT systems can significantly reduce soil CO 2 emissions compared to CT systems in corn production. 873 874 E. Z. Nyakatawa et al.

“…The experiment was composed of three tillage methods (conventional-till, no-till, mulch-till), two cropping systems (cotton in summer-fallow in winter; cotton in summer-rye in winter) and two sources of nitrogen: poultry litter and ammonium nitrate. In total, there were twelve treatments laid out in a randomized complete block design with plot size of 8 m by 9 m having eight rows of crops [20]. There were three replicates from three blocks.…”

Macro and micro nutrients enrichment from poultry litter amendment, tillage, and crop rotation have been investigated to determine their impacts on crop yield, soil and environmental sustainability. This study was conducted to evaluate the soil arsenic (As), copper (Cu), lead (Pb), nickel (Ni) and zinc (Zn) enrichment that could result from the long term effect of poultry litter amendments and tillage practices on selected soil properties at the Alabama Agricultural Experiment Station, Belle Mina, AL. Soil samples were collected in 2006 from plots established in 1996 that received yearly poultry litter applications with three tillage systems, conventional-till (CT), no-till (NT), and mulch-till (MT); and at three depths (0-10 cm, 10-20 cm, and 20-30 cm) that received poultry litter based on 100 kg total N ha -1 yearly. An untreated control was also included in the study. Soil pH values at the 0-10 cm were greater or equal to the lower depths. Copper and Zn concentrations were significantly higher for all tillage systems at the 0-10 cm depth compared to the 10-20 and 20-30 cm depths and decreased with increasing depth. For example, at 0-10 cm depth Cu concentrations were 58, 66 and 65 and Zn were 13, 24 and 22 percent higher than the control for the CT, MT and NT tillage practices respectively. These results demonstrated that Cu and Zn did accumulate in the surface soil after 10 annual applications of poultry litter but not at phytotoxic levels in contrast to As, Pb, and Ni regardless of the tillage practices.
