NACHURS CropMax® is a concentrated liquid micronutrient fertilizer developed to provide crops with essential secondary nutrition during planting, seeding, sidedress, foliar, and fertigation applications.
Its premium 2-0-2 formulation supplies boron, copper, iron, manganese, molybdenum, and zinc. The copper, iron, manganese, and zinc are fully chelated with EDTA, helping protect these nutrients against reactions that can reduce their availability in the soil or when combined with other fertilizer materials.
Unlike partially chelated or complexed micronutrient sources, the fully EDTA-chelated nutrients in NACHURS CropMax are designed to remain available for plant uptake. This makes CropMax a practical option for addressing micronutrient requirements identified through soil testing, tissue analysis, or professional fertility recommendations.
NACHURS CropMax offers excellent compatibility with NACHURS in-furrow starter fertilizers and may also be combined with compatible liquid fertilizers, fertilizer suspensions, and nitrogen solutions. Its flexible application options allow growers to incorporate targeted micronutrient nutrition into a wide range of crop fertility programs.

Role of the Micronutrients
Boron
Boron supports new plant growth, pollination, seed production, and the balance and movement of sugars and starches within the plant.
Copper
Copper functions as a co-enzyme and helps activate plant enzymes involved in converting amino acids into proteins. It also supports healthy new growth.
Iron
Iron is required for chlorophyll formation and supports important processes such as respiration, photosynthesis, and symbiotic nitrogen fixation.
Manganese
Manganese contributes to chlorophyll development and functions as a catalyst within several plant enzyme systems.
Molybdenum
Molybdenum supports nitrogen metabolism by helping convert nitrogen into amino acids. It also assists legumes with the fixation of atmospheric nitrogen.
Zinc
Zinc supports starch formation, proper root development, seed production, and crop maturity.
Ideal Applications
- In-furrow starter fertilizer programs
- Soil application at planting or seeding
- Sidedress micronutrient programs
- Foliar micronutrient treatments
- Fertigation systems
- Crops with soil-test-confirmed micronutrient requirements
- Crops with tissue-analysis-confirmed deficiencies
- Programs requiring fully EDTA-chelated micronutrients
- Liquid fertilizer and nitrogen-solution combinations
General Application Rates
In-Furrow
Apply 1–2 pints per acre. NACHURS CropMax is formulated for compatibility with NACHURS in-furrow starter fertilizers.
Foliar
Apply 1–2 pints per acre with enough spray volume to provide thorough and uniform crop coverage.
Fertigation
Apply 1–2 pints per acre. Extremely hard water or water containing high total dissolved solids may affect product performance.
General Mixing Instructions
- Add approximately one-third of the fertilizer to the application tank.
- Add any additional compatible agricultural chemicals.
- Fill the tank with the remaining fertilizer.
- Add the recommended amount of NACHURS CropMax.
- Agitate thoroughly to create a uniform mixture.
Always perform a jar test before field mixing CropMax with fertilizers, pesticides, or other agricultural products.
Why Growers Choose NACHURS CropMax
Micronutrients are required in relatively small amounts, but they perform essential functions throughout the crop’s life cycle. Limited nutrient availability can affect root development, chlorophyll production, enzyme activity, nitrogen use, pollination, and seed formation.
NACHURS CropMax delivers six important micronutrients in one concentrated liquid formulation. Its fully EDTA-chelated copper, iron, manganese, and zinc are designed to remain available to the crop, helping growers incorporate dependable micronutrient nutrition into existing soil and foliar fertility programs.
Use CropMax according to soil testing, plant tissue analysis, and professional fertility recommendations. Excessive boron application may damage crops, and molybdenum-containing fertilizers should only be used on responsive soils. Crops containing high molybdenum levels may be harmful to grazing ruminants.
Protect micronutrient availability. Support essential plant functions. Maximize every fertility application.
