Fertilizer Micro & Secondary Nutrients

Micronutrients are used by plants in relatively small amounts and contribute to maximizing plant yield and quality. Pestell Minerals & Ingredients sulphate micronutrients are highly water soluble and highly plant available.

Talk to your agronomic advisor about soil testing and plant tissue analysis to determine micronutrient levels and recommended rates of application.

Fertilizer Micronutrients

Zinc [Zn]

Zinc plays an important role in chlorophyll production, cell elongation, grain formation and protein synthesis. Supplying zinc to a young, developing plant is beneficial, especially in cold soils when zinc availability is reduced. The earlier a crop is planted the greater the need for row-applied zinc.

Responsiveness is relative to when the soil contains low available levels of the micronutrient. Levels may vary based on your location.

Manganese [Mn]

Manganese is involved in several plant processes, including photosynthesis and dry matter production. Manganese also helps plants resist disease and tolerate abiotic stresses such as heat and drought.

Copper [Cu]

Copper is crucial for proper enzyme activity, chlorophyll formation and seed production. In Ontario, copper deficiency is uncommon on mineral soils, however, may be found on very sandy, high pH soils. Organic soils may also have copper deficiencies.

Boron [B]

Boron is important for cell development, sugar and starch formation and translocation. Deficiencies are more likely to occur on sandy or gravelly soils with low organic matter and low water holding capacity.

Sulphur [S]

Sulphur is sometimes called the 4th macronutrient, indicating its importance in crop production. In recent years, sulphur deficiencies have become more prevalent due to lower industrial emissions and higher crop yields. Sulphur is necessary for chlorophyll formation, protein production and nitrogen metabolism.
