A white fungal network called hyphae, not plant roots, is the principal structure for the uptake of many important nutrients in the plant kingdom.

Years ago, before the Internet, Mother Earth News magazine was my main source of gardening information. They have decades of free articles online, which in my opinion is a remarkable treasure trove. The following article is just a sample.

“Nurture the ancient, symbiotic relationship between mycorrhizal fungi and plants’ roots for increased garden harvests and healthier soil.

We still define natural habitats primarily in terms of plants and animals, the two kingdoms of life we can see with unaided eyes. The greatest amount of biological activity and the largest diversity of species and genes, however, come from the other four kingdoms science now recognizes: bacteria, archaea (a less-studied division of life-forms formerly considered bacteria), protists (mostly single-celled algae and protozoans), and fungi. The vast majority of these members are microscopic in size. They cannot be seen with the naked eye, but we now know they permeate soils and suffuse waters. They drift en masse through air. They thrive not only on the surface of every plant and animal, but within them as well. From the upper reaches of the atmosphere to the bottom of the seas, down into the rock layers and outnumbering the stars in the known universe, microbes are literally the creatures that make Earth a living planet.

… the mycelium becomes an auxiliary root system that’s in contact with a subterranean volume of soil from several hundred to 2,500 times greater than what the plant could reach alone.

… Mycorrhizae, not plant roots, are the principal structures for most nutrient uptake in the plant kingdom.

… mycorrhizal fungi numbers can decline for lack of live roots to colonize. Douds advises avoiding empty beds by keeping plants, whether food crops or cover crops growing at all times… Douds’ favorite, hairy vetch.

How to Promote the Plant-Mycorrhizae Partnership
• Minimize soil tilling
• Always keep live plants in your beds, even in winter
• Rotate crops within your beds
• Avoid pesticides and chemical fertilizers
• Avoid applying too much phosphorus; a soil test every few years is a good idea”
[Plus keep the soil covered with mulch.]

  1. This reply is not about the post.

    Today in Arlington,TX city workers were filling sand bags for possible flooding from the remanents of Tropical Storm Bill. I thought the tool they use to fill the bags would be of interest to you and your readers. I just realized that I can’t attach a picture. Go here. http://youtu.be/vTW6G0IXn10 For the news story. You can see the rack at about 2 minutes in and then again at about 2:45.

    • We’ve covered several similar sand bag filling devices. Search our blog for keywords tools or mechanized earthbag. You could make something similar with a bucket for about $1. Plus, unlike sand moist soil does not flow through the complex devices.
