Too much of a good thing can be a bad thing. That’s certainly true for nitrogen fertilizers.

Without enough nitrogen, crops don’t grow well. Yields are reduced significantly.

Applying too much nitrogen fertilizer, on the other hand, can hurt the environment. Nitrogen can enter the watershed, polluting aquatic ecosystems. Microbes can also convert the excess nitrogen into nitrous oxide, a greenhouse gas implicated in climate change.

Ground penetrating radar isn’t something from the latest sci-fi movie. It’s actually a tool used by soil scientists to measure the amount of moisture in soil quickly and easily.

Spring in America’s heartland is often wet. That makes its soil too soft for planting. One solution to that issue is tile drainage. Growers insert a series of pipes (drain tiles) under their fields, which drains water from the soil into nearby streams and lakes.

Coffee is one of Brazil’s biggest crops. Brazil’s favorable climate helps coffee beans ripen and be ready for picking during a concentrated period of weeks. This makes mechanical harvesting an economically reasonable choice.

A (wo)man is only as good as his or her tools. In the case of soil scientists, they are only as good as the tools and methods they use. And when it comes to estimating soil organic carbon stocks, new research shows not all tools give the same results.

Interest in organic farming is growing. However, controlling weeds without synthetic herbicides, as organic certification requires, is challenging. Scientists are studying alternative tools for weed management. One such tool is propane-fueled flame weeding.

Farmers make a lot of decisions. One of the most important is how much fertilizer to apply to their crops, and when to apply it. Applying more than necessary or at the wrong time can waste resources, impact the environment, and cut into narrow profits.

We often “flush it and forget it” when it comes to waste from toilets and sinks. However, it’s important to be able to track this wastewater to ensure it doesn’t end up in unwanted places. A group of Canadian scientists has found an unlikely solution.

The future of weeding is here, and it comes in the form of a robot.

Farmers and gardeners know their soil texture can make a big difference in their success. Different plants have different needs for water, nutrients, and air. When they grow in soil that has the right texture, it is easier to deliver the right amount of water, fertilizer, or pesticide to the plants. Then they grow better.
