- Which four spectral bands are typically included in USDA Farm Service Agency four-band imagery?
- Red, green, blue and near-infrared
- Ultraviolet, X-ray, thermal and radar
- Only red and near-infrared
- Blue, ultraviolet, microwave and lidar
- How does John Deere's See & Spray reduce herbicide use?
- By spraying the entire field uniformly
- By using computer vision to spray only detected weeds
- By banning all herbicides
- By spraying only at night
- What is 'variable-rate technology' in precision agriculture?
- Charging farmers different prices for seeds
- Changing the speed of the tractor randomly
- Applying different amounts of inputs to different field zones
- A type of crop insurance
- Which model architecture did the cited 2025 crop-weed paper evaluate for edge weed detection?
- A speech-recognition Transformer
- A rule-only spreadsheet parser
- A large language model trained on contracts
- A lightweight convolutional neural network
- In the USDA ERS 2023 report, variable-rate technology had been adopted on what share of planted acreage for winter wheat, cotton, sorghum and rice?
- Between 5 and 25 percent
- Less than 1 percent for every crop
- Between 50 and 75 percent
- All planted acreage
- What did the cited USDA precision-farming field study report about yield patterns across years?
- Yield patterns were identical every year
- Yield patterns changed yearly and had little similarity between years
- All management zones produced the same yield
- AI consistently improved yield in every zone
- How is NDVI commonly calculated from red and near-infrared reflectance?
- Red plus blue divided by soil moisture
- Thermal radiation minus wind speed
- Near-infrared minus red, divided by their sum
- Plant height multiplied by fertilizer rate
- Why can variable-rate technology use input maps instead of a single field-wide rate?
- Every part of a field has identical needs
- Maps eliminate the need for agronomic decisions
- The system changes crop genetics while spraying
- Soil and crop conditions can vary across zones within a field
