Many urban gardeners know that adding ingredients like compost and mulch to their soil has great benefits. But it can be difficult to know what to add and why. Researchers at Purdue University gathered scientific evidence about one specific soil addition, leaf mold compost, and how it benefits tomato plants.

Underneath the surface, plant roots are hard at work. Roots, of course, are how plants get water and minerals from the soil. But digging into how different root systems affect crop yields has been challenging for researchers.

Not that long ago, weeds spread at a much slower rate. Seeds would spread to nearby soil and move perhaps a few feet each year or would be transplanted by birds who flew with them several miles away. In today’s interconnected world, though, weeds can hitch a ride on a truck, boat, or even an airplane. What once might’ve taken generations to spread weeds from one region to another now takes no time at all.

Planting cover crops is a beneficial agricultural practice. One of their many benefits is to cover soil for times when farmers cannot plant cash crops like corn and soy – over the winter, for example.  But it is not as simple as just growing cover crops in between growing seasons. Farmers have multiple decisions to make about optimizing cover crop production.

Spills and leaks of petroleum products wreak havoc on the environment. They can contaminate soils and pose significant threats to humans, animals, plants, and soil microbes. Cleaning up petroleum contamination can be energy and time-consuming, however, one of the fastest methods of decontaminating soils is called thermal desorption.

“When it rains, it pours.” This phrase is meant to mean that bad news comes in waves. Unfortunately, that’s true with real rain, too. While rain is usually welcome for various reasons, in developed area like cities and towns, it can produce a big problem: polluted runoff.Long cylinders filled with soil underneath a rainwater spout

Lentils are an important and popular food in many parts of the world. They are also a nutritional powerhouse. This versatile legume is a great source of protein, carbohydrates, and fiber, and high in mineral nutrients and vitamins like iron, zinc, magnesium, potassium, and vitamin B.

The Great Plains in the United States are well known for a rich history and expansive grasslands. This region is synonymous with ranchers herding cattle across the plains and a valuable resource for a growing population.

Understanding how a crop will grow in various places is key to getting more farmers to grow it. Rye is a cereal grain grown in parts of Europe, and although not a commonly grown crop in other regions, its characteristics make it a valuable option for farmers.
