“…Organic amendments provide (i) carbon that restores, sustains, or improves soil physical properties (Powlson et al 2011), and (ii) macro-and micronutrients for crop uptake. The effective use of organic amendments is often limited by our ability to accurately predict the N mineralization rate of the organic-N to inorganic-N (Goss, Tubeileh, and Goorahoo 2013). Properly crediting the value of organic amendments as fertilizer in the years following their application will improve manure's nitrogen use efficiency (NUE) (Carter, Westermann, and Jensen 1976;Webb et al 2013).…”

To efficiently use nitrogen (N) while protecting water quality, one must know how a second-year crop, without further N fertilization, responds in years following a manure application. In an Idaho field study of winter wheat (Triticum aestivum L.) following organically fertilized sugarbeet (Beta vulgaris L.), we determined the residual (second-year) effects of fall-applied solid dairy manure, either stockpiled or composted, on wheat yield, biomass N, protein, and grain N removal. Along with a no-N control and urea (202 kg N ha ). All materials were incorporated into a Greenleaf silt loam (Xeric Calciargid) at Parma in fall 2002 and 2003 prior to planting first-year sugarbeet. Secondyear wheat grain yield was similar among urea and organic N sources that applied optimal amounts of plant-available N to the preceding year's sugarbeet, thus revealing no measurable second-year advantage for organic over conventional N sources. Both organic amendments applied at high rates to the preceding year's sugarbeet produced greater wheat yields (compost in 2004 and manure in 2005) than urea applied at optimal N rates. On average, second-year wheat biomass took up 49% of the inorganic N remaining in organically fertilized soil after sugarbeet harvest. Applying compost or manure at greater than optimum rates for sugarbeet may increase second-year wheat yield but increase N losses as well.Abbreviations CNS, carbon-nitrogen-sulfur ARTICLE HISTORY

“…O nitrogênio (N) presente na cama de aves tem sido objeto de estudo em várias partes do mundo haja vista que, quando este resíduo é aplicado ao solo sem critérios técnicos, este elemento apresenta grande potencial poluente (Bolan et al, 2010;Goss et al, 2013), uma vez que está presente em quantidades significativas neste resíduo e sua forma nítrica é bastante móvel no solo (Dynia et al, 2006). Além disto e por questões de ordem prática e econômica, não raramente os estercos são adicionados ao solo em doses superiores à capacidade de seu suporte.…”

A eficiência fertilizante da cama de aves depende da capacidade de mineralização de seus nutrientes que se encontram na forma orgânica. O potencial poluente deste resíduo, por outro lado, depende, dentre outros fatores, da rapidez da nitrificação dos compostos nitrogenados. O presente estudo objetivou quantificar a mineralização líquida e a nitrificação do N presente na cama de aves após sua aplicação em um Cambissolo Húmico álico. Os tratamentos consistiram na incubação com o solo de doses de cama (equivalente a 0; 4; 8; 16 Mg ha -1 ) e uma dose de ureia (204 kg ha -1 de N), todas incorporadas ou aplicadas sobre a superfície do solo. Determinaram-se os teores de amônio e nitrato no solo aos 2, 6, 12, 19, 26, 32 e 48 dias após o início da incubação. Os teores de amônio diminuíram e os de nitrato aumentaram com o tempo de incubação em função do processo de nitrificação; esta conversão foi mais rápida quando a cama de aves foi incorporada ao solo em relação à aplicação na superfície. A recuperação do N da cama de aves na forma mineral foi pequena, independentemente da forma de aplicação ao solo, com valores que decresceram em função da dose de 22,0 para 15,7% para as doses 4 e 16 Mg ha -1
