  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • European Space Agency contributes to ocean carbon cycle research

    The Earth’s oceans play a vital role in the carbon cycle, making it imperative that we understand marine biological activity enough to predict how our planet will react to the extra 25,000 million tonnes of carbon dioxide humans are pumping into the atmosphere annually. The colour of oceanic seawater depends largely on the number of microscopic phytoplankton, marine plants that live in the ...
