Magnetic Chemical Fertilizer Unit Constructed in Shenzhen
Batch production of coated multi-element mag-netic chemical
fertilizer developed by Shenyang Institute of the  Chinese
  Academy  of  Sciences  has  been  conducted  in  Compound
  Fertilizer  Plant  of  Shenzhen  Liaohe  Tongda  Chemical
  Industrial  Group  Corporation.   As  a  research  result
  combining  chemical  fertilizer  technology,     magnetic
technology and  new  material  technology,   the  magnetic
chemical fertilizer has a high nutrient  utilization  rate
and multiple functions and  can  promote  the  sustainable
development of agriculture. It has therefore aroused great
interest both at home and abroad.  A  rapid  progress  has
also been  achieved  in  its  research,   development  and
application. The magnetic chemical fertilizer developed by
Tongda Chemical Industrial Group  Corporation  includes  a
variety  with  the  nitrogen,   phosphorus  and  potassium
content higher than 30% and a variety with  the  nitrogen,
phosphorus and potassium content  higher  than  40%.   The
trial-use has proved that the effect of the variety with a
medium concentration of 30% on early  rice  has  surpassed
the effect of imported compound fertilizers  with  a  high
concentration.
