Recommended Products for Soybeans
These AgConcepts biological inputs are specifically matched to the nutrient demands and growth cycle of Soybeans during the Spring-Summer season.
ZyDrive
BiologicalIn-furrow and seed treatment biological inoculant that delivers nitrogen-fixing bacteria, phosphate solubilizers, and mycorrhizal fungi directly at the germinating seed.

Enhance
FoliarFoliar fertilizer that delivers phosphate and essential nutrients directly through the leaf — applied during vegetative-to-reproductive transition for maximum crop response.

Application Guide for Soybeans
At Planting / Transplant
Apply ZyDrive in-furrow or as a soil drench at transplant to establish nitrogen-fixing bacteria, phosphate solubilizers, and mycorrhizal fungi in the root zone before the crop sees its first stress event.
Vegetative Growth
Apply Enhance as a foliar spray during active vegetative growth to deliver phosphate and essential micronutrients directly through the leaf — timed to the period when the crop's nutrient demand is climbing fastest.
Reproductive / Pre-Harvest
Apply ProMax (OMRI-Listed, PHI 0 days) to suppress soil-borne pathogens and foliar disease pressure through the critical reproductive window and up to harvest day — with zero re-entry interval and zero pre-harvest interval.
Soybeans Farm Operations Snapshot
What it takes to run a typical Soybeans operation — equipment, inputs, and cost benchmarks.
Typical Scale
500–3,000 acres
Avg Yield
50–55 bu/acre
Gross Revenue/Acre
$440–$550
Total Input Cost/Acre
$310–$430
⚙ Key Equipment
- 🚜
Row-Crop Tractor
Same unit as corn; 150–300 hp typical
- 🌱
Planter or Drill
Row planter (30") or drill (7.5–15"); narrow rows yield advantage
- 🫘
Combine + Flex Head
Flex head cuts losses; head height critical for soybean lodging
- 💦
Sprayer
60–90 ft boom for herbicide and fungicide applications
- 🔄
Seed Inoculator
Rhizobia inoculant (ZyDrive) at planting; especially on new soy ground
Equipment specs represent a typical mid-size operation. Scale up or down as appropriate.
$ Cost Per Acre Breakdown
📋 Key Inputs & Costs
Soybean Seed
$60–$90140,000–160,000 seeds/acre; trait packages vary widely
Herbicide
$40–$65Pre-emerge + post-emerge; waterhemp and Palmer amaranth driving cost up
Phosphorus (P2O5)
$30–$50Lower rate than corn; replenish what crop removes
Potassium (K2O)
$35–$55Soybeans remove significant K; soil test critical
Fungicide
$18–$28R3 timing; white mold and sudden death syndrome key targets
Rhizobia Inoculant
$5–$12ZyDrive establishes N-fixing nodules faster; critical on new ground
Biological Inputs
$5–$12Super Hume + AgZyme; enhances nutrient cycling and root mass during R1–R3
💧 Water Needs
Dryland in most production areas; soybean is more drought-tolerant than corn but R1–R3 moisture critical
🧬 Where Biologicals Fit
Soybeans fix their own nitrogen — but only with healthy rhizobia populations. ZyDrive rhizobium inoculant improves nodulation speed and count, especially on fields returning to soybeans after corn. Pair with Super Hume to improve phosphorus availability during pod fill when demand is highest.
Pro Tip
Waterhemp and Palmer amaranth resistance is pushing herbicide costs up 20–30% per year in the Midwest. Healthier soil biology (better root mass, deeper moisture access) reduces drought stress that weed competition exploits. Biologicals are indirect weed management.
