Healthy soils have a high rate of respiration. Soil respiration refers to the production of carbon dioxide by soil organisms. This includes respiration of plant roots, the rhizosphere, microbes and fauna. The concentrations of both O2 and CO2 are largely dependent on microbial activity, which in turn depends on the availability of organic carbon compounds
In my last newsletter, I talked about how the introduction (inoculation) of new microbes can benefit poor soils and struggling crops. On the other side of the coin, devastating fungi, bacteria and other microbial parasites can contribute to a host of crop diseases. In the 1960s, millions of elm trees in Britain, France and the
Rainforests on infertile wet soils support more than half of all plant species. Shrublands on infertile dry soils in southwestern Australia, jokingly called “knee-high tropical rainforests,” support another 20 percent of all plants. Nutrient scarcity is the common denominator. In both ecosystems plants team up with soil bacteria or fungi to gather nutrients more efficiently.
Hello Friends of Andaman Ag, There’s considerable discussion about biological agriculture these days but what does it mean? A brilliant scientist, Dr. William Albrecht, Head of Agronomy at the University of Missouri in the late 50’s and early 60’s wrote about the importance of maintaining a healthy soil and formulated the Albrecht soil test. It was
