Nitrogen is the main nutrient added to cereal crops like corn, which makes them grow faster and stronger. But too much of a good thing could sometimes have negative outcomes. Too much nitrogen can run off with rainwater or leach through to soil and contaminate groundwater. Now, a simple, rapid and reliable test can determine the nitrogen amount in soil. …
UF Study: To Help Prevent Harmful Algal Blooms, Limit Nitrogen and Phosphorus
Algal blooms can kill fish and harm a lake’s ecosystem, but by reducing two nutrients together such as nitrogen and phosphorus – not just one or the other — water managers might limit the blooms in lakes and rivers, a new University of Florida study shows. To come to this conclusion, UF Institute of Food and Agricultural Sciences researchers used …
