Application Guide for Cotton
At Planting
Apply AgZyme and a biological inoculant in-furrow or as a seed treatment to establish beneficial soil biology from day one and accelerate early root development.
Early Season
Follow up with Super Hume or Huma-K during early vegetative growth to improve cation exchange capacity and ensure micronutrients are plant-available.
Mid-Season
Apply Enhance or AgCor to support the critical reproductive and fruit-fill stages, maximizing yield potential and quality metrics.
Cotton Farm Operations Snapshot
What it takes to run a typical Cotton operation — equipment, inputs, and cost benchmarks.
Typical Scale
500–3,000 acres
Avg Yield
1.2–1.8 bales/acre (1 bale = 480 lbs lint)
Gross Revenue/Acre
$700–$1,100
Total Input Cost/Acre
$560–$800
⚙ Key Equipment
- 🚜
Row-Crop Tractor
200–350 hp; beds formed at planting
- 🌱
Precision Cotton Planter
4–8 row, finger pickup meters; precision spacing critical for canopy closure
- ⚙️
Cotton Picker / Stripper
Picker for humid East; stripper for Plains; $500K+ machines often shared
- 📦
Module Builder
Field-build modules (25,000 lbs) for transport to gin
- 💦
High-Clearance Sprayer
PGR, defoliant, and late-season insecticide applications critical

$ Cost Per Acre Breakdown
📋 Key Inputs & Costs
Cottonseed
$70–$105Trait packages vary; seeding rate 2–3 seed/ft for 3–4 plant/ft stand
Nitrogen (N)
$85–$13080–120 lbs N/acre; split applications for fruiting window efficiency
Herbicide
$55–$90Pigweed resistance driving cost up significantly; layered pre + post programs
Plant Growth Regulator
$15–$25Pix / mepiquat chloride; controls rank growth and improves boll retention
Defoliant
$25–$40Critical for picker efficiency; timing off = significant yield loss or quality damage
Biological Inputs
$7–$15AgZyme + Super Hume; improves nutrient cycling in sandy coastal plain soils
💧 Water Needs
Dryland in Texas, Georgia; supplemental irrigation improves yield 0.4–0.8 bales/acre in critical drought periods
🧬 Where Biologicals Fit
Cotton is a heavy feeder grown on soils that have often been depleted by decades of continuous cotton or corn-cotton rotations. Biological programs that rebuild soil CEC (Super Hume) and improve nitrogen cycling (AgZyme) are especially high-value in the sandy Coastal Plain soils of Georgia, Alabama, and Mississippi.
Pro Tip
Rank growth (too-tall, vegetative cotton) is a top yield limiter. PGR helps, but it's treating a symptom. Biologically active soils with better N release timing — releasing N when the plant needs it during boll development rather than all at once — naturally reduce rank growth risk.
