Farm Futures has partnered with the Ecology and Agriculture Spatial Analysis Laboratory (EASAL) at Kansas State University to bring these maps to you. Each map is composed from satellite data taken over a two-week period. The EASAL maps show current vegetative health for the past two weeks and compare vegetative health with the previous two-week period, with the previous year and with the long-term average. Green reflects healthy vegetative development, while brown reflects a lack of healthy vegetative biomass production.
Satellite imagery shows rapid active vegetative growth in the southeastern quarter of the country, with abnormally warm temperatures encouraging crop growth. However, much of the Midwest continues to see limited crop growth.
This satellite image shows that vegetative growth is clearly advanced relative to the 23-year average for this time of the year in the southeastern quarter of the country. That robust growth is especially evident in Arkansas, Oklahoma, Kansas and Missouri. This year's mild temperatures have also encouraged increased vegetative/crop growth relative to normal in the Northern Plains and the Great Lakes region. It also shows that dryness continues to inhibit crop growth in West Texas.
Mid-April moisture in the center of the country encouraged additional vegetative/crop growth in the center of the country, relative to early April. However, some deterioration is noted in the Midwest after a freeze in the region, combined with ongoing dryness. Considerable vegetative growth was seen in mid-April along the West Coast.
Satellite imagery shows that vegetative growth is ahead of year ago levels across much of the country, due to the warm conditions seen for much of this year thus far, relative to normal. Some areas in the western high Plains continue to see limited vegetative growth due to ongoing dryness, along with the far Southeast.
