High Cost for High Yields

January 22nd, 2014 | Posted by XiteBio in Uncategorized - (0 Comments)
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.

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 … Read more

Summer & WInter

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 … Read more

Scientific research being conducted on rhizobia bacteria

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 … Read more

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.

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 … Read more

Crop rotation enables better disease control and nutrient management, leading to healthy crops

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 … Read more

Percent of nitrogen supplied by n fixation

  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 … Read more

natural soil microflora-conceptual image

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 … Read more

How AGPT Works

It’s common knowledge that Mother Nature can be cruel to farmers. Once crops have been seeded, they can be left exposed and vulnerable to the harshest of weather conditions. Farmers know this, and take every precaution they can to protect their investment. Nothing can provide guaranteed protection, but every step taken gives their crops a … Read more

petri plate containing microbes

Farmers never want to hear that their crops have been infected with a virus or fungus, but it may not be long before that attitude begins to change. Scientists are discovering that some viruses have the ability to help infected plants better tolerate different stresses. Dr. Marilyn Roossinck is a professor at Penn State University … Read more

dry soil

For farmers, the impact of a drought is not only felt while it is happening, but also for several years after. According to Randall Miles at the University of Missouri, dry soil can take at least two years to recover to normal conditions. Randall found that soil in the Midwest was dry as deep as … Read more
