Figure 1. The Vegetation Condition Report for Kansas for June 28 – July 4, 2016 from K-State's Precision Agriculture Laboratory continues to show greatest NDVI values are confined to extreme northeast Kansas, along the Missouri River. The continued dry, warm weather has limited vegetative activity in the rest of the state. That is particularly noticeable in the Flint Hills, in Osage, Coffey, and Lyons counties.
Figure 2. Compared to the previous year at this time for Kansas, the current Vegetation Condition Report for June 28 – July 4, 2016 from K-State's Precision Agriculture Laboratory shows much lower photosynthetic activity across eastern Kansas, while the west is seeing higher NDVI values. The area of greatest increase in photosynthetic activity is confined to southwest Kansas. Rainfall has continued to be well distributed in the region and crop progress continues ahead of last year at this time.
Figure 3. Compared to the 27-year average at this time for Kansas, this year's Vegetation Condition Report for June 28 – July 4, 2016 from K-State's Precision Agriculture Laboratory shows below-average vegetative activity is greatest in the east central part of the state. The rapid change to hot, dry conditions has accelerated plant develop and stressed newly planted row crops. Impact from this week's rainfall won't be visible for a while.
Figure 4. The Vegetation Condition Report for the U.S for June 28 – July 4, 2016 from K-State's Precision Agriculture Laboratory shows low NDVI values West Virginia and western Pennsylvania. Much warmer temperatures are driving the downturn in conditions as parts of the Midwest are reporting lower-than-average precipitation. In southeastern Missouri and northern Arkansas conditions are more favorable, although the Boot Heel region of Missouri missed the most recent rains.
Figure 5. The U.S. comparison to last year at this time for June 28 – July 4, 2016 from K-State's Precision Agriculture Laboratory shows that lower NDVI values are most evident in the Mountain West where drier-than-average conditions, coupled with extremely hot weather, have stressed vegetation compared to last year. In the East, heavy rains have limited NDVI values.
Figure 6. The U.S. comparison to the 27-year average for the period June 28 – July 4, 2016 from K-State's Precision Agriculture Laboratory shows increased areas of below-average photosynthetic activity. The boundary in Texas of favorably moist conditions in the west to excessively wet conditions in the east has shrunk. Lower-than-average photosynthetic activity is also widespread across the Mid-Atlantic states. Widespread heavy rains were common in that area last week.
