POTASSIUM METAPHOSPHATE is one of the newer potassium and phosphorus carriers that contains approximately 40% potash and 60% phosphoric acid. Bartholemew and Jacob have shown by pot culture tests that crop yields with potassium metaphosphate are comparable with those obtained by supplying the equivalent amounts of potassium and phosphorus with potassium sulfate and superphosphate. Potassium metaphosphate has been under trial at Cornell University for the past 4 years. This paper is presented to indicate the yields and plant composition which resulted from the use of this fertilizer as compared with other phosphorus carriers when the potassium was supplied as potassium chloride.
