Abstract

"PRODUTO DE LIBERAçãO CONTROLADA, PRODUTO BASEADO EM URéIA DE LIBERAçãO CONTROLADA, E, PROCESSOS PARA TRATAR PARTìCULAS, PARA ALIMENTAR NUTRIENTES àS PLANTAS E PARA ALIMENTAR NUTRIENTES AOS RUMINANTES". Suplementos de alimentação baseados em uréia de liberação controlada para animais ruminantes e nutrientes de plantas baseados em uréia de liberação controlada são compreendidos de partículas ou grânulos compreendidos em todo ou na parte principal de uréia ou tendo uréia em ou sobre às superfícies externas destes, e um revestimento de rede de polímero interpenetrante resistente à umidade nas partículas compreendido dos produtos de reação de uréia e um poliisocianato, e os produtos de reação de poliisocianato, uma resina alquídica tendo no mínimo uma ligação dupla em cada unidade repetida e um óleo tendo no mínimo uma ligação dupla, as ligações duplas sendo reativas com um ou outro e com elas mesmas. Os nutrientes de planta revestidos têm uma taxa substancialmente linear de liberação de nutrientes para o solo durante um período controlado de tempo, por exemplo, 30 a 120 dias. Os suplementos de alimentação de ruminante revestidos têm uma taxa substancialmente linear de liberação de NPN no rume durante um período controlado de tempo, por exemplo, 12 a 24 horas. A razão de nutrientes para controlar agentes é alta, liberação controlada é alcançada com gasto mínimo, e os produtos são económicos para usar.
