The "Ammoniator": a Device to Enrich Waste Solutions with Nitrogen¹

Utilization of liquid wastes as fertilizers is sometimes limited by the large volumes (due to low N concentrations), which must be applied to provide optimum N rates for crops. A device (ammoniator) is described which facilitates the enrichment of waste slurries with anhydrous ammonia (or other concentrated liquid N sources) to improve the value of the wastes as nutrient sources for crop production. The ammoniator is inexpensive to construct, simple and safe to operate with ordinary precautions for NH, use, and efficient in increasing the plant-available N concentration in waste slurries two- to three-fold. The device is adaptable for use in liquid manure tanker wagons or in pits and holding tanks.

Key Words: Anhydrous ammonia • Plant nutrition • Animal wastes • Sewage sludge
