摘要

AERIAL IMAGERY REVEALS CROP PROBLEMS DIFFICULT TO SEE FROM THE GROUND. For a new view of crop production, try rising above it all. Aerial images of fields are useful tools for detecting crop variations and equipment problems that are hard to see fromthe ground, says Tom Oswald, a Cleg-horn, IA, farmer who's used aerial imagery for several years. From a bird's-eye view, you can spot nitrogen (N) deficiencies, poor irrigation-water distribution, drainage problems and uneven seeding or fertilizer application. Geo-referenced aerial photos can show storm damage, soil compaction, disease infestations, even marauding wildlife. Aerial images are also helpful for finding old tile lines or soil variations.
