Finding a way to make nitrogen-fixing bacteria more competitive once they are added to the soil has been one of the hardest problems for seed inoculant companies to overcome. Special strains of the newly added bacteria, called rhizobia, are specifically  selected for their strong ability to remove nitrogen from the air and "fix" it into a form can be used by plants. These strains perform very well in controlled laboratory settings. The problem begins once the bacteria has been applied to the field. Soils contain an infinite number of...

[caption id="attachment_644" align="alignright" width="273"] A "debit/credit" system developed by soil scientist Rigas Karamanos calculates that Canadian Prairie soils went down approximately 30 lb/ac of nitrogen in 2013 as a result of record breaking yields.[/caption] 2013 brought big yields to farmers across the Canadian Prairies. By the end of the year, grain bins were almost literally bursting at the seams. Some farms had such high outputs that they were unable to find storage for their entire crop, and were forced to simply store it on the ground. High yields are...

Many changes in the environment are easily noticed as seasons move from one to the next, though some are less noticeable than others. Just as life above ground has to adapt to changing weather, so does life below ground. Here is a summary, released by the University of Minnesota, of how soil organisms alter their behavior throughout the year: Spring: Soil tillage brings warming air and crop residues for food below the surface, which begins a high level of activity. Organisms start to release nutrients, heat and carbon dioxide into the soil Summer:...

Soils that contain high salt content are a critical problem for agriculture in many parts of the world. Saline soils are a major stress on plants, and also limit the growth of beneficial soil bacteria. Salt also inhibits nodulation for those plants that depend on it for nitrogen. Recently in the country of Uzbekistan, A researcher named Dilfuza Egamberdieva discovered several strains of bacteria that can not only survive in saline soils, but also have properties that help boost plant growth. These salt-resistant bacteria have the ability to directly...
