“…Lowering the pH of anaerobically digested dairy manure to pH 3.8 increased P availability by 500% , whilst a lesser decrease to pH 4.5 resulted in 43-100% of the total P present in dairy manure becoming available (Shen et al, 2011). Szogi et al (2008) demonstrated that 60-80% of the total P in poultry manure was released from organically bound P following acid treatment. Treating with a base to increase alkalinity also enhances P availability as demonstrated by a 50-70% increase in available P in dried sewage sludge (Stark, 2005).…”

“…Acid leaching (for dairy manure and poultry litter), use of chelating agents (dairy manure), microwave treatment (dairy manure), anaerobic digestion (dairy manure) are the key pre-treatment methods used for farm based waste (Szogi et al, 2008;Moody et al, 2009;Zhang et al, 2010;Qureshi et al, 2008).…”

“…Albeit more concentrated in the biochars, solubility of some elements can diminish with pyrolysis. While 19.5% phosphorus from raw poultry litter was extracted in water by Qiu and Guo [24], Szogi and Vanotti [25] extracted up to 80% using organic acids in a treatment process called "quick wash". Upon conversion into biochars Cantrell et al [26] reported 0.5-31% reductions in the amount of soluble-P in poultry manure biochars from raw feedstock.…”

“…A diferença de produção de MSRA e MSPA entre a cama constituída por areia e as demais possivelmente deve-se a diferenças nas taxas de liberação do P. Na cama constituída por areia, a quantidade total de cada nutriente vem exclusivamente dos dejetos animais e restos de ração, ao passo que nas demais camas esses também fazem parte da constituição de cada material utilizado como cama para as aves, o qual precisa ser decomposto para que os nutrientes sejam liberados para as plantas. (Miles et al, 2003;CFQSRS/ SC, 2004;Szogi &Vanotti, 2009). Os valores de N mineral total presentes no solo na determinação realizada cinco dias após a aplicação dos adubos ao solo não diferiram entre os tratamentos com camas de aves em relação àqueles que não receberam N (Figura 1).…”

“…Para as camas de aves, a TR do N variou entre 25 e 34 %, com pouca diferença entre essas (Figura 4). As camas de aves proporcionaram menos da metade da TR, em relação aos fertilizantes minerais (71 %), em razão de que grande parte do N presente nos dejetos animais encontra-se em formas orgânicas que não se tornam disponíveis às plantas num curto espaço de tempo, pois as doses aplicadas foram com base no teor de N total desses materiais (Miles et al, 2003;CFQSRS/SC, 2004;Szogi & Vanotti, 2009).…”
