Workflows by use case

Row crop — 50 ha corn/soy (US Midwest)

1. Spring base fertilizer: Climate FieldView combines last season + satellite imagery → variable-rate prescription map; -20% fertilizer.
2. Post-planting: DJI Agras T40 covers 1 ha in 5 minutes; ±2 cm auto-steer; runs at night.
3. Growing season: weekly drone flight; Taranis flags disease early; spot-spray drops pesticide ~50%.
4. Reproductive stage: Granular AI delivers "harvest Aug 15 ±3 days"; line up combines and dryers.
5. Harvest: auto-steer combine; yield + moisture logged at 1m resolution; feeds next season's prescription.

Outcome: +10% yield, -20% fertilizer cost, -50% pesticide cost, -300 labor hours/yr, +15% net farm income.

Vegetable (cabbage / lettuce, 5 ha family farm)

1. Pre-plant: Climate FieldView soil map; SCiO spot NPK and pH; AI blends optimal fertilizer.
2. Transplant → growth: DJI Agras for protection; xarvio Scouting maps weed pressure.
3. Heading: daily Plantix leaf photos catch disease early; spot-spray only.
4. Two weeks pre-harvest: Granular forecasts volume; pre-sell to wholesale, retail, direct-to-consumer.
5. Shipping: market-demand AI routes loads to highest-priced markets first.

Apple orchard (3 ha, Pacific Northwest / Northern Japan)

1. Pruning: drone canopy scan; AI 3D-visualizes branches to remove.
2. Bloom: AI flower count; fruit-set prediction informs thinning plan.
3. Growth: Plantix leaf photos detect rust and leaf spot early.
4. Harvest: color + size AI prioritizes which trees and which fruit first; sweetness leads.
5. Sorting: AI cameras grade M/L/2L automatically; -30% labor.

Dairy (100 head, Northern US / Hokkaido)

1. Per-cow monitoring: Connecterra collar tracks rumination, gait, intake 24/7; AI flags heat, mastitis, fertility issues.
2. Feeding: Cainthus image AI proposes optimal ration from body condition.
3. Milking: Lely Astronaut robot integration; per-cow yield and quality in real time.
4. Reproduction: heat detection at 95% accuracy (vs. 70% human); +20% AI conception rate.

Tool deep-dives

Climate FieldView ($3-15/ha/yr) — largest farm-data platform

Run by Bayer Crop Science. 180M ha and 250K farms globally. Satellite × tractor data × weather, AI-fused: variable-rate prescriptions, yield forecasts, profitability analysis. Default for US corn and soy.

John Deere See & Spray ($50-150K/sprayer) — AI spot spraying

Built on Blue River Technology. Camera + AI on the sprayer; sprays weeds only. -77% herbicide proven. High capex but 3-5 year payback. Dominant in the US, rolling out to Japan in 2027.

Plantix (Free-$10/mo) — global pest/disease ID with 10M+ users

Snap a leaf, get 99%-accurate diagnosis with treatment in your language. Adopted by smallholders worldwide; 500+ crops, deep pest/disease library.

Taranis ($15-30/ha/yr) — ultra-high-resolution drone scouting

0.3 mm/pixel imagery picks up weeds, pests, and nutrient deficiency at the plant level. Standard on US large-scale operations; AI labels "the 12 spots to act on tomorrow."

2026 trends

1. Autonomous tractors — John Deere 8R Autonomous, Monarch Tractor — 24/7 unmanned operation
2. Harvest robots — Tortuga AgTech (strawberry), Advanced Farm Tech (asparagus) — commercial deployment
3. Vertical farming AI — AeroFarms, Plenty, Bowery Farming — large-scale indoor automation
4. Carbon credits — Indigo Ag, Nori — AI measures soil carbon for tradable credits
5. Robot weeders — Naïo Technologies, FarmWise — mechanical weeding, herbicide-free
6. Climate adaptation — Climate FieldView serves "extreme-weather scenario" cultivar and timing recommendations
7. Cheap sensors — Teralytic at $200/unit (10× cheaper than 5 years ago) — small farms can adopt
8. Gene-editing AI — Inari, Pairwise — accelerated climate-resilient cultivars

Pitfalls

• Capex over-reach — See & Spray's $150K is a large-farm play; under 5 ha, manual + drone is plenty
• Connectivity dependency — Climate FieldView outages happen; keep paper backups
• AI blind spots — even Plantix misses rare diseases; maintain extension agent / co-op contact
• Legacy machinery — older equipment can't accept retrofit IoT; budget for replacement
• Aging operators — 80-year-old farmers struggle with smartphone UIs; pair with successor / family
• Data sovereignty — Bayer / John Deere ingest your field data; consider co-op-run alternatives in sensitive regions

ROI

50 ha row crop — annual

Cost: Climate FieldView $750 + DJI Agras T40 $30K (5-yr amortization $6K/yr) + sensors $5K (5-yr $1K) = ~$8K/yr.

Yield: +10% × 50 ha × $1,000/ha avg revenue = +$5K (illustrative; varies by crop and price).

Inputs: -$10-30K/yr in fertilizer + chemicals depending on scale.

Labor: -300 hrs/yr (~$6K at $20/hr).

$8K/yr in → $25-50K/yr out. 3-6× ROI conservative on a midsized operation.

2026 reframes farming as "intuition + experience + AI = +30% yield." Climate FieldView, John Deere, Plantix, Taranis — yield up, costs down, hours down. The line: AI handles data collection, analysis, and optimization; humans retain final calls, neighbor relationships, and weather-curveball judgment. With succession, climate, and food security pressing simultaneously, AI isn't a luxury — it's the realistic path forward for agriculture.
