Ótima palestra (em inglês) da PhD em microbilogia do solo Kristine Nichols. A seguir deixo a descrição do video no youtube: Soil as the heart of the farming ecosystem is driven by biological activities to increase soil organic matter, which represents a small percentage of the soil by weight, but controls over 90% of the soil functions. This presentation introduces viewers to the concepts of 1) rhizosphere biology, the area immediately surrounding the plant root with the highest concentration of microbiological activity; 2) soil "livestock" consisting of bacteria, fungi, nematodes, protozoa and microarthropods and representing the greatest concentration of biomass anywhere on the planet; 3) glomalin, a biological glue that holds soil together and improves soil aggregation; and 4) building soil biota to improve soil quality, increase nutrient cycling, and long term sustainability using cover crops, no-till, and other sustainable farming practices.
