At the 2012 Corn Production Symposium, presenter Don Yadon discussed many key elements that have, and will impact yields the most in the future. Genetics, Bio Technology, Farm Practices and Management and Biological Systems were top of the list.
“For every soil management problem lad operators face, there is a biological solution”
A healthy population of Micro and Macro Organisms recycles 30 tons of soil every 12 months.
Some important Microorganisms and their Role In Soil
Bacteria – Are decomposers who convert energy in soil organic matter into forms useful to the rest of the microorganisms in the soil Decomposers are important in immobilizing or retaining nutrients in their cells and preventing the loss of these nutrients, such as nitrogen in the root zone.
Rhizobia Bacteria – Are Nitrogen Fixing Bacteria that convert atomospheric N for Legume crops Important for Mineralization, and Important for the N cycle.
Algae – are present in most of the soils where moisture and sunlight are available. They are photo autotrophic, aerobic organisms and obtain C02 from atmosphere and energy from sunlight and synthesize their own food. Plays important role in the maintenance of soil fertility.
Mycorrhizal fungi – colonize the roots of most plant species, forming a mutually beneficial relationship that has a significant role in nutrient uptake and protects against root feeding nematodes and pathogens. Mycorrhizal fungi are especially important in supplying plant available phosphorus in exchange for carbon. They live inside the plants root system.
Fungi – are comprised of microscopic cells that grow in long threads called hyphae. Fungal hyphae bind soil particles into macro-aggregates which increase the soil’s ability to absorb and retain water. Fungi also play an important role in the breaking down of organic matter into useful forms and assists in nutrient retention and disease suppression.
