Hi, I have worked on projects analyzing NPK fertilizer formulations and reviewing micronutrient blends for turf and landscape applications, including recommendations for balanced nutrient release in warm-season grasses. I also assisted in evaluating controlled-release fertilizer options and preparing technical documentation that followed U.S. fertilizer labeling and registration guidelines. I'd love to share my experiences with you. Best regards, Epa

Dear Sir/Madam I am a chemist from Zimbabwe and holds B.Sc. Chemistry and Biochemistry from Zimbabwe as well as M.Sc. Chemistry from the University of Siegen in Germany. I would like to be part of your project in fertilizer formulation. Fertilizers generally have three main nutrients, potassium, phosphorous, and nitrogen. Potassium is absorbed as potassium ions and phosphorus as phosphate and nitrogen as nitrates. Compound fertilizers can be potassium nitrate, ammonium nitrate, or potassium phosphate. Fertilizers are made mainly from ammonia and nitric acid or phosphoric acid. The ammonia is produced by the Haber process whereby hydrogen comes from the electrolysis of water and oxygen from the fractional distillation of air. Nitrogen is required for growth of plants, potassium for flowering and fruit development and phosphorus for root development. Yours faithfully Brian Chiunye
