Similarly, growing the cover crop later into the spring (delayed termination) can result in greatly increased biomass due to warmer growing conditions, with corresponding increases in nutrient uptake, root development, and soil health benefits (same field pictured on March 15, left, and May 2, right).

WINTER COVER CROPS - delayed termination
Similarly, growing the cover crop later into the spring (delayed termination) can result in greatly increased biomass due to warmer growing conditions, with corresponding increases in nutrient uptake, root development, and soil health benefits (same field pictured on March 15, left, and May 2, right).

On-farm sampling of cover crop performance, conducts using quadrats and camera equipment, is used to calibrate remote sensing vegetation indices to calculate cover crop biomass and vegetative cover from satellite.

WINTER COVER CROPS - On-farm performance
On-farm performance of winter cover crops is variable, ranging from minimal biomass due to poor agronomy and weather conditions; low biomass due to limited soil nutrients and late planting dates; medium biomass under typical growing conditions; and high biomass due to good agronomy, favorable weather, and abundant availability of soil nutrients.

Wintertime satellite imagery of Maryland farmland shows areas with higher amounts of green vegetation in deeper red colors. Bare fallow fields are distinguishable from cover crops and winter cereal crops, and evergreen forest is distinguishable from deciduous forest.

Monitoring Suspended Sediment and Flow along the Mississippi River: Episode 2
In this video segment, the U.S. Geological Survey (USGS), Lower Mississippi Gulf Water Science Center (LMGWSC) scientists give a detailed description of how the USGS uses Acoustic Doppler Current Profilers, (ADCP) to measure flow along the lower Mississippi River.

Monitoring Suspended Sediment and Flow along the Mississippi River: Bonus Episode
In this video segment, the U.S. Geological Survey (USGS), Lower Mississippi Gulf Water Science Center (LMGWSC) scientists give a preview of how the USGS is currently working to design a new generation large river sampler. This new sampler will incorporate all functions of previously developed USGS depth and point samplers.
