豆农场的设备投入；可能改种牛草近一些

1. Core Equipment Needed for Soybean Farming

Equipment	Purpose	Typical Cost (USD, new)	Notes
Tractor (100–250 HP)	Power source for all major tasks	$60,000 – $180,000	Used units can be half the price
Planter / Seeder	Precise row planting for soybeans	$25,000 – $120,000	Air seeders for large acreage
Sprayer	Weed, pest, and nutrient application	$15,000 – $80,000	Self-propelled sprayers for efficiency
Combine Harvester with Soybean Header	Harvesting	$150,000 – $600,000	Critical — used combines are common
Grain Cart / Wagon	Moving harvested soybeans	$15,000 – $60,000	Improves harvest logistics
Grain Storage (Bins + Dryer)	On-farm storage and moisture control	$50,000 – $300,000	Optional but helps sell at better prices
Tillage Equipment (Disc, Harrow, Cultivator)	Land preparation	$10,000 – $80,000	No-till farms may skip this
Truck or Trailer	Transport to elevator or crusher	$30,000 – $120,000	Grain dump trailer ideal

2. Investment Scenarios

Farm Size	Mechanization Level	Estimated Equipment Investment	Example Setup
Small (≤ 200 acres)	Mid-level	$150K – $300K	Used tractor + planter + small combine
Medium (200–1,000 acres)	High	$400K – $900K	New tractor, sprayer, modern combine
Large (>1,000 acres)	Full automation	$1M – $3M+	Precision GPS equipment, multiple combines, drone scouting
