Legume species-specific bacteria form a symbiotic relationship with the legume roots. The resulting nodules contain the bacteria. These bacteria can biologically fix nitrogen (N) from the air, making it available to the plant.

You’d be surprised how much topsoil is lost through wind erosion, and even more surprised to learn how long it takes to rebuild it. Texas A&M is looking at how no-till and covers can help manage this problem.

Over the last 3 days my phone, email and twitter account has been blowing up with questions surrounding poorly nodulated soybeans and my thoughts regarding applying foliar nitrogen to alleviate those symptoms.

Soybean acres continue to grow and that means that we will likely have more acres of soybeans planted into "virgin" soils, where there has been no recent history of soybeans.

Soybeans obtain up to 70% of their total nitrogen requirement from biological nitrogen fixation conducted by Rhizobia bacteria colonies (nodules) living on soybean roots. If the nodules fail to form, the plants will become deficient in nitrogen and significant yield reductions can occur.
