Production Agriculture

Plants can’t do without phosphorus. But there is often a ‘withdrawal limit’ on how much phosphorus they can get from the soil. That’s because phosphorus in soils is often in forms that plants can’t take up. That affects how healthy and productive the plants can be.

The world produces more corn by weight than any other cereal crop. Corn, also known as maize, is a staple food in many countries. But farmers growing corn face many challenges, such as drought, diseases, and pests.

Outside Asia, no country produces as much rice as does Brazil. It is the ninth largest rice producer in the world. Average annual yields are close to 15 million tons.

Plants need water—but what about when it’s running low? Is it possible to use less water and still have healthy crops?

How do you boost soil water content and soil health without irrigating? Best cover it with a layer of straw, a new study concludes.

Researchers have good news for growers. Farmers raising a nitrogen-hungry crop like sweet corn may save up to half of their nitrogen fertilizer cost. The key: using a faba bean cover crop.

Ragweed, its pollen potent to allergy sufferers, might be more than a source of sneezes. In the Midwest, the plant may pose a threat to soybean production.

Scientists have found that ragweed can drastically reduce soybean yield.

Soybean is rich in protein, which is great for the humans and animals eating it. But this high protein content comes at a cost.

A ditch containing woodchips may look unassuming—but with a name like bioreactor it’s guaranteed to be up to more than you think.  

How do you host tens of millions of migratory waterfowl every year? The Rainwater Basin of southeast Nebraska provides a vital resting stop and feeding station. There, the native wetland plants produce enough seed to replenish the birds—some of them threatened or endangered species—for their long journey.
