[caption id="attachment_606" align="alignright" width="300"] To survive long-term, rhizobia must learn to fight for valuable resources. This can have a negative impact on their ability for future nitrogen fixation.[/caption] One reason why many farmers do not inoculate their soybeans is because they feel that their fields already have high numbers of rhizobia that inoculating isn’t worth it. They feel that the rhizobia population has been built up sufficiently over years of soybean inoculation that enough are already present to provide adequate root nodulation. While it is true that rhizobia levels...

For thousands of years, crop rotation has been used to improve soil nutrient management while also controlling the outbreak of disease. A group of scientists in Norwich, England recently discovered how this happens. All soil is filled with billions of different microscopic species. What was discovered was that different crops will favor the growth of different types of these species. When wheat was grown during the study, it would promote an increase in bacteria. When oats or peas were grown, there would be an increase in nematodes and...

Nitrogen fertilizer management is important for the success of any crop.  It is an expensive input, so growers are always looking for the best way to reduce application costs while still increasing yields. Nitrogen fertilizer is produced from natural gas, which makes the cost of the fertilizer vulnerable to changes in the supply and price of the gas. High yield crops have a high nitrogen requirement. However, some crops are able to supply their own nitrogen, while adding more to the soil for future crops. Legume crops are able...

Farmers benefit as much as anyone from healthy and active soils. A variety of life lives within the soil, ranging from microscopic bacteria to earthworms several inches long, most of them contributing to making the soil a vibrant growing environment for plants. Here are several processes performed by soil organisms that directly impact farmers: Nutrient Cycling: managing nutrients is a very important role for soil organisms. When living matter dies, the nutrients that are stored within it need to re-enter the soil and change form so that other living...
