But that is not all that matters. The real world is a more complicated place, as I shall explain in a moment. And that is why a floating exchange rate regime makes sense for Canada. The case typically made for a floating rate for Canada is that it gives us the chance to run an independent monetary policy. That is true.
Over-irrigation of the soil takes out all of the embedded nutrients and makes the soil fallow. In addition, it can lead to erosion and runoff, which can make the ground less stable and less able to hold fruits, vegetables, and plants.
With light, sandy soil, the organic matter will help hold the water after rain or irrigation. If your soil has plenty of organic matter -- such as decayed leaves or compost -- worked into it, it will stay moist after a rain or irrigation. Organic matter acts like a sponge, holding moisture near the surface. That's good for onions, which have shallow roots and can't tap water or nutrients deep in the soil. If you're wondering about soil acidity or alkalinity (pH), onions do best if the soil pH is between 5.5 and 6.5, a little on the acid side.
