Sequestar Chelated Micronutrients

BRANDT Sequestar chelated micronutrients are ideal for hydroponics and fertigation programs requiring targeted iron, manganese, zinc, and copper nutrition. Choose individual chelated nutrient sources to fine-tune your fertilizer formulation around crop requirements, irrigation-water chemistry, and growing conditions.

Choose the right iron chelate

Sequestar 13.2% Fe EDTA provides water-soluble chelated iron for acidic to mildly acidic nutrient programs.

Sequestar 11% Fe DTPA provides water-soluble chelated iron for hydroponics and fertigation where greater pH stability than EDTA is needed.

Sequestar 6% Fe EDDHA offers an iron source for alkaline conditions, including calcareous soils where elevated pH can limit iron availability.

Targeted manganese, zinc, and copper nutrition

Sequestar 13% Manganese EDTA, 14% Zinc EDTA, and 14% Copper EDTA microgranules provide individual micronutrient options for adjusting your feeding program. Separate nutrient sources let you adjust specific elements without relying on a fixed-ratio micronutrient blend.

Select formulations based on root-zone pH, water chemistry, crop requirements, and application method. Use water, media, and tissue testing to guide nutrient adjustments, and follow each product label for application rates and mixing instructions.
