Abstract
An improved liquid fertilizer distribution manifold operating in two stages. An accumulator piston located above the primary and secondary ports provides for two stages of flow. A broad range of regulated flow for site-specific farming results in precise, accurate and timely application of liquid fertilizer and pesticides. An elevated piston seal flange in the manifold allows flow to be exact with plugged or partially plugged primary orifices. Manifolds are produced in single tier and double tier arrangements to improve efficiency. The same manifold can be applied to NH3 pressure increasing systems. NH3 pressure decreasing systems and liquid fertilizer and pesticide systems.
