Weed learning module
Self test
- What is the weed seed bank? Why is it interesting to researchers? Why is it important to farmers?
- Organic methods frequently improve soil physical quality (tilth). How could improved tilth help cultivators kill weeds?
- How can adding a green manure be compatible with both creating a healthy soil and killing weed seedlings with pathogenic fungi that are known to attack crops?
- Nutrients promote the growth of both crops and weeds.
- Why do we hypothesize that high rates of compost will favor weeds more than crops?
- In what ways do the data collected so far support this hypothesis, and in what ways do they not support the hypothesis?
