Copper, Iron, Manganese and Zinc. Four essential micronutrients, copper, iron, manganese and zinc, were measured at the Alberta Environmentally Sustainable Agriculture (AESA) Soil Quality Benchmark Sites. Copper is very important for a plant's reproductive growth stage and affects chlorophyll production.
Grass, like all plants, requires specific types of nutrients in order to thrive. These nutrients are broken down into macronutrients and micronutrients. Most fertilizers supply the macronutrients: nitrogen, phosphorous and potassium. Nitrogen supports green growth, while phosphorous plays an important role in plant photosynthesis and energy transfer.
