I will say two things about this.
One, we should know and assess what our soils are across this county, and ensure we have the right labelling for everything.
Two, we have to understand how soil works and understand that if we don't take care of it or feed it, we will see the degradation of it. There are places where farmers have decided that fertilizer or manure are not accessible. Perhaps the livestock operations are too far away, or perhaps the fertilizer is priced to the point where they can no longer afford it because the margins are too small, so they don't put enough on. You can watch how, in two or three years, the soil changes colour and the plants get smaller and smaller. In the end, you just end up with weeds.
