Ultra Yield Micronutrients manufactures quality zinc sulfate fertilizers under the Ultra Yield and BLU-MIN®  trade names. Ultra Yield micronutrients manufactures both liquid and crystalline zinc formulations. Zinc is an essential nutrients in plants, animals and human nutrition. Ultra Yield products are manufactured in liquid and crystal form for use in fertilizaton of a large variety of crops. As a micronutrient, zinc is needed in relatively small quantities compared to N P K fertilizers but is essential for top yields, high quality and peak performance. Micro does not refer to the impact of the nutrient but only to its required quantity. If a crop is micronutrient deficient it can cost as much yield as having a macronutrient deficiency.
