Two of my instructors at Merritt, different classes, mentioned this movie when talking about soil and water. You will find out why clay soils are good for dry regions and how dryland farming works on clay soils. And why we are now told to plant in native soil rather than amended native soils. This is not generally accepted yet. If you buy a rose plant or fruit tree you will still be sold soil amendments along with your plant. But it's better to put the soil amendments on top and let the worms work it down and let the humic acid do its magic.
