Abstract:
A growth promoter for aquatic plants, which increases the carbonate concentration in water to promote the growth of aquatic plants and contains phosphate as an active component, and a method for applying said growth promoter, which comprises placing an aqueous solution or dispersion of the growth promoter in a container of which one end is narrowly opened and placing the container in water in a water tank thereby to allow the growth promoter to ooze through the narrowly opened end.
Abstract:
A cellulosic medium for growing mushrooms is disclosed. A liquid mixture containing sources of soluble carbon and nitrogen is fermented and mixed with cellulosic material. The so-treated cellulosic material is held at a temperature and for a time sufficient to allow substantial reduction of organisms damaging to mushroom culture. The cellulosic material then is cooled to a temperature suitable for spawning.
Abstract:
Phosphorus values are recovered from phosphate crystal mother liquor by contacting the liquor with finely divided calcium salts at elevated temperatures to precipitate hydrated octacalcium phosphate. Ca/P input is specific.
