With harvest wrapping up this fall our attentions are being drawn to the next growing season already. Now’s the time to choose what seed hybrid to plant, which tillage method to implement, how much fertilizer to apply, and in some cases what source of that fertilizer to use.

Solving environmental problems usually just means cleaning up the mess people have made. But scientists are increasingly interested in creating something valuable from pollution.

Healthy soil contributes to healthy crops. Farmers know this, so they do what they can to ensure their soil is in good shape.

An important part of strong legumes pastures not only includes suitable species and varieties, but also successful nodulation with appropriate root nodule bacteria. 

The rising use of nitrogen-based fertilisers is driving up global emissions of nitrous oxide, a lesser-known greenhouse gas, complicating efforts to limit climate change, scientists reported in a study .

Draining waterlogged farm fields helps crops but can leach nitrogen into waterways.

Researchers from Flinders University are investigating organic nitrogen fertiliser to return nitrogen to soil without the need for chemicals.

University of Illinois researchers put hyperspectral sensors on planes to quickly and accurately detect nitrogen status and photosynthetic capacity in corn.

Soil organic carbon is a cornerstone of soil health. It improves soil structure while enhancing water- and nutrient-holding capacity, key factors for any agricultural production system. To build it up, farmers incorporate crop residues into soils.

A study led by environmental scientists at Rice University's George R. Brown School of Engineering puts numbers to the toll of reactive nitrogen species produced in America's croplands.
