Abstract
A continuous process for the non-destructive recovery of natural nitrogenous materials as highly available particulate agricultural nutrients, employing natural materials such as poultry waste, waste water treatment sludge, alfalfa meal, hatchery waste, feathermeal, corn gluten meal and bloodmeal in a fluid bed reactor-granulator where basic natural materials are acidified to pHs of 3.0 to 6.5 and formed into hardened particulates during a retention time between 4 and 20 minutes at a temperature between 70.degree. and 120.degree. C. and discharged free of caramelization before nitrogen losses from decomposition amounts to 0.5 percent of the natural nitrogenous materials. The continuous process provides a new natural nitrogenous particulate agricultural nutrient composition free of caramelization.
