The soil experiment involved field work. Well, it was sort of field work as it involved digging a small hole at the bottom of the garden to bury some digital thermometer probes. Now we have to monitor soil temperature over a 24-hour period. G will do the midnight reading and I'll do the 6 a.m. one. OK, 7 a.m. I'm not getting up that early.
Tomorrow there will be weighing of soil and determining water and air content.
