Magnesium ammonium phosphate

Magnesium ammonium phosphate (MAP)is produced from hydrated magnesium sulphate, phosphoric acid or a conc. soln. of a very soluble salt of phosphoric acid and, if necessary, ammonia. The exit materials or their solns. are reacted at 0-60 degrees C pref. 25-30 degrees C with a satd. soln. of ammonium sulphate (AS). This soln. is heated enough, pref. 55-65 degrees C, for AS developing with the reaction, to be able to be removed from the heated soln, and for the exit material or solns. of them, to be inserted, only with such a water content that exceeds the bonding power of the MAP. The heat content of the warmed soln. increases with the heat of reaction of the final loss of evaporation sufficiently to allow the initial cold of the AS satd. mother liquor to be reachieved by water withdrawal. Either an excess of this mother liquor results which is useful for other purposes or AS results as a solid by cooling down as described, or both can occur. The MAP hydrate is led away from the AS soln.

These compositions are useful in in odor control.

METHOD FOR DIRECTLY PREPARING A FERTILIZER BY USING STRAWS AND PREPARED STRAW ORGANIC FERTILIZER

A method for preparing a fertilizer using straws and prepared straw organic fertilizer; the method includes: composting straws, spraying a compositing microbial solution containing amino acids to start decomposition of straws, and adjusting humidity of a straw compost, times of spraying a solution of product nutrients, component of the solution to obtain an up-to-standard commercial straw organic fertilizer; and keeping the composting temperature about 70° C. for long time by adjusting the turning time of the straw compost and collocation time of spraying the solution. The method is based on rich organic matters and nutrients in straws, and need for organic fertilization by soil and the like, and by improving the nutrition condition and growing condition of microorganisms of the straw compost, crop straws are directly prepared into high-quality commercial organic fertilizer in short time, so crop straws are completely utilized, and high-quality commercial organic fertilizer product is provided for fertilization. 110-. (canceled)11. A method for directly preparing a fertilizer by using straws , comprising:(1) stacking the raw straws after shipping into a straw pile of 5 meters or higher in height; performing the first spray by spraying as pray solution directly on the straws, wherein the liquid volume in the first spray is controlled to such an extent that an aqueous solution flows out from the bottom of the pile; performing the second spray when the temperature of the pile reaches 70° C. and continues for 3-5 days; performing the third spray after 3-5 days of high temperature composting after the second spray; and spraying once every 3 to 5 days hereafter, so that a straw compost is prepared after 6-7 operations as such, wherein the liquid volume in the second and later sprays is controlled to such an extent that the water content in the pile reaches 55-60% , and no more aqueous solution flows out from the bottom of the pile;whereinthe solution in the first spray is ...
