When we look at the root­ing depth of a weed, the most lim­it­ing fac­tors are de­ter­mined by the root’s abil­ity to prop­a­gate through the soil, tap­ping into both ma­jor and mi­nor nu­tri­ents re­quired. If your land has a sub­soil com­paction pan – a tight sec­tion of the soil be­neath the top layer – then the abil­ity for any plant to de­velop roots down into the pro­file is much more dif­fi­cult. Sim­i­larly, if you have a wet pad­dock or lawn, my pref­er­ence is to al­ways dig a hole and have a look. There are a num­ber of soil char­ac­ter­is­tics that can be contributing to a weed bur­den, and sub­soil com­paction might be one of them.
