  Author(s): Andrey Norov*, Denis Pagaleshkin and Pavel Fedotov
  
  JSC “NIUIF”, the oldest (founded in 1919) and the only one in Russia scientific research institute for phosphorus containing fertilizers, developed an innovative flexible technology of production of slow release NPKS / PKSfertilizers with a controlled dissolution rate and controlled nutrient supply into the soil solution. These fertilizers are environmentally safe, nonradioactive; practically do not contain compounds of harmful heavy metals (arsenic, cadmium, lead, mercury, chromium, etc.). Besides the main nutrients (nitrogen, phosphorus, potassium) they also contain sulfur and calcium in a plant available form. The dissolution rate is regulated by changing the ratio between the water soluble and plant-available forms of phosphorus, as well as by addition of ammonium salts. The technology is waste free, moreover, it allows to process wastes and.. Read More»
