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.

Application Guide for Soybeans

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.

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.

📋 Key Inputs & Costs

🫘

Soybean Seed

$60–$90

140,000–160,000 seeds/acre; trait packages vary widely

🌿

Herbicide

$40–$65

Pre-emerge + post-emerge; waterhemp and Palmer amaranth driving cost up

🟡

Phosphorus (P2O5)

$30–$50

Lower rate than corn; replenish what crop removes

🟤

Potassium (K2O)

$35–$55

Soybeans remove significant K; soil test critical

🍄

Fungicide

$18–$28

R3 timing; white mold and sudden death syndrome key targets

🦠

Rhizobia Inoculant

$5–$12

ZyDrive establishes N-fixing nodules faster; critical on new ground

🧬

Biological Inputs

$5–$12

Super 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

Labor: 0.4–1.2 hours/acre/yearHarvest: Late September through October (Midwest)

🧬 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.
