A Balanced Diet for Plants

Macronutrients: Nitrogen (N), Phosphorus (P), and Potassium (K)
Macronutrients are the primary nutrients required in the largest amounts and form the foundation of most fertilizer programs. They play critical roles in plant growth, yield development, and overall crop performance.

Secondary Nutrients: Calcium (Ca), Magnesium (Mg), and Sulfur (S)
Secondary nutrients are essential for plant development and productivity. They are referred to as “secondary” because crops generally require them in smaller quantities than macronutrients—not because they are less important.

Micronutrients
Micronutrients are required in very small amounts, but they are vital to plant health and physiological function. Deficiencies can limit crop performance even when other nutrients are sufficient. Essential micronutrients include:
Boron (B), Chloride (Cl), Copper (Cu), Iron (Fe), Manganese (Mn), Molybdenum (Mo), Nickel (Ni), and Zinc (Zn).

Nutrient Stewardship and Fertilizer

Fertilizer is an essential tool in Arkansas crop production when used responsibly, efficiently, and sustainably. Nutrient stewardship emphasizes applying plant nutrients in a manner that meets crop needs, protects soil and water resources, and supports long-term farm productivity. Through sound management practices, fertilizer contributes to sustainable and profitable agriculture while reinforcing the stewardship of Arkansas’s natural resources for future generations.

Why Nutrient Stewardship Matters in Arkansas

Arkansas agriculture is diverse, productive, and vital to the state’s economy. Responsible nutrient stewardship helps ensure fertilizer is used efficiently to support crop yields while protecting Arkansas’s soil and water resources. By following sound, science-based nutrient management practices, the agricultural community can strengthen farm profitability, meet environmental responsibilities, and sustain productive farmland for future generations.
