  1. 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
  2. John Deere의 See & 스프레이는 어떻게 제초제 사용을 줄입니까?
    • 전 현장에 균일하게 분사하여
    • 컴퓨터 비전을 이용해 감지된 잡초만 살포함으로써
    • 모든 제초제를 금지함으로써
    • 밤에만 뿌리면
  3. 정밀농업에서 '가변율 기술'이란?
    • 농부들에게 종자에 대해 서로 다른 가격 부과
    • 트랙터의 속도를 무작위로 변경
    • 다양한 필드 영역에 다양한 양의 입력 적용
    • 농작물 보험의 일종
  4. 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
  5. 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
  6. 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
  7. 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
  8. 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
