Soil phosphorus availability and lime: More than just pH?
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 ...

Making 'mulch' ado of ant hills: Ant hill mulch improves soil moisture
Ants can be annoying little insects. In your home, they make army-like lines to any crumbs on your floor. In your home's frame, carpenter ants can do a job of eating away your walls. But what about outside? Do ants play a ...

Poor soils lose carbon regardless of crop residue and nitrogen inputs, shows study
Let's say you're a corn grower farming on low-fertility soil. How do you go about making that soil healthier and more fertile? Many farmers think if they add plenty of nitrogen fertilizer, that nutrient, along with carbon, ...

How much nitrogen does corn get from fertilizer? Less than farmers think
Corn growers seeking to increase the amount of nitrogen taken up by their crop can adjust many aspects of fertilizer application, but recent studies from the University of Illinois Urbana-Champaign show those tweaks don't ...

Microbes play important role in soil's nitrogen cycle
Under our feet, in the soil, is a wealth of microbial activity. Just like humans have different metabolisms and food choices, so do those microbes. In fact, microbes play an important role in making nutrients available to ...

Unexpected culprit—wetlands as source of methane
Wetlands are an important part of the Earth's natural water management system. The complex system of plants, soil, and aquatic life serves as a reservoir that captures and cleans water. However, as cities have expanded, many ...

Forest soils release more carbon dioxide than expected in rainy season
Current carbon cycle models may underestimate the amount of carbon dioxide released from the soil during rainy seasons in temperate forests like those found in the northeast United States, according to Penn State researchers.

Determining outcomes of on-farm best practices
Baking a cake from scratch has more variables than baking one from a boxed mix. Though one can debate why—and when—cake mixes were developed, they are popular, and produce a uniform product. (They were really patented ...

One crop, two ways, multiple benefits
Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes - naturally occurring bacteria in the soil - work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant ...
