What is it with Weeds?

Nature’s way of telling you that there are problems in your soil is if your soil contains weeds. Knowing your weeds is the first step in eliminating them or using them. Here are some of the things weeds do.

  • Protect the soil from erosion
  • Replenish organic matter, and feed and restore soil life
  • Absorb, conserve, and recycle soluble nutrients that would otherwise leach away
  • Absorb carbon dioxide from the atmosphere
  • Restore biodiversity
  • Provide habitat for insects and animals

BINDWEED (Convolvus) Tight, crusted soil, low humus.

BROOM SEDGE (Andropogon virginicus) Depleted oxidized soil, low in calium and possibly magnesium, poor  soil structure and possible overdose of high-salt fertilizer.

FOXTAIL BARLEY (Hordeum jubatum) Wet soil, possibly high in salts and low in calcium, compacted, possibly acid, unavailable potassium and trace elements.

COMMON BURDOCK (Arctium minus) High iron, acid, low calcium, excess of gypsum, dolomite lime, ammonium sulphate plus lime.

DANDELION (Taraxacum officinale) Low calcium, organic matter not decomposing.

DOCK (Rumex) Wet, acid soils.

 

CHEAT, CHESS (Bromus secalinus) Wet, compacted, puddled, fine particles, no crumb structure.

CHICKWEED (Stellaria media) High organic matter at surface but low mineral content.

CHICORY (Cichorium intybus) Fairly good soil, clay or heavy soil.

COCKLEBUR (Xanthium pennsylvanicum) Good soil, high phosphorus but low zinc.

CRABGRASS (Digitaria sanguinalis) Tight crusted soil, low calium, inadequate decay of organic matter.

FALL PANICUM (Panicum dichotomiflorum) Anaerobic, compacted soil.

FOXTAIL, GIANT FOXTAIL (Setaria) Tight, wet soil, possible high magnesium, seed germinates in anaerobic conditions.
