I need a good method for continuous, automatic (computer-connected)
soil moisture monitoring at several points. I plan a field experiment with 
potted birch seedlings. Weighing of pots or soil plugs is not possible in
this case. I'm going to try resistance blocks. How to make them? Is there
any other surface material than gypsum? Thanks!
