Flexible use across multiple crops beyond corn when needed.
Complement Corn
Complement Corn is a high-efficiency nutritional fertilizer engineered to support early corn development by supplying a balanced blend of N-P-K and essential chelated micronutrients. Its formulation—built from ammonium phosphate, potassium hydroxide, seaweed extract, sugar beet molasses, and fully chelated zinc, manganese, and copper—delivers readily available nutrients that enhance seedling vigor, root expansion, and early stand uniformity. The product is optimized for in-furrow or pre-emerge applications, where precise nutrient placement accelerates early crop growth and strengthens stress tolerance.
The label recommends 4–8 quarts per acre applied in-furrow at planting or as a pre-emerge spray prior to seedling emergence, ensuring that phosphorus and zinc—critical for early root initiation—are available when the crop needs them most. The formulation is compatible with standard starter fertilizer programs but should not be tank-mixed with herbicides unless cleared by a licensed agronomist.
Complement Corn may also be used across additional crops such as soybeans, alfalfa, vegetables, berries, and canola, extending its utility across diversified operations. Packaged in 2.5-gallon jugs and 250-gallon totes, it fits both standard and high-acreage systems. The SDS classifies it as a skin and eye irritant, reinforcing the need for standard PPE during mixing and handling.
Overall, Complement Corn provides a reliable, field-ready nutrient system that supports early vigor, more uniform emergence, and improved stand establishment—key drivers of yield potential in modern corn production.
