Hi Ken Thanks for this, very interesting.

Well, I've no right to say "That's a pity" (he said, saying it), English is much too imperialistic... Anyway that's probably enough to work on Ken, many thanks! >Best regards, > >Ken >Keith > >I forgot to add that the residual can be used for >fertilizer. Where I live, the wet paddy method of >rice production is used and the rice straw is burned >rather than “plowed” back into the paddy. That's a waste, such useful stuff! And the soil needs some return. Composting would be better. (Add 50% water hyacinth, for instance, then there's no need for animal manure.) Are you aware of this, by the way? http://ciifad.cornell.edu/sri/ SRI Homepage/System of Rice Intensifcation Well worth a look, or better than a look. >The >Trichoderma Reesei fungus should be killed or it may >start attacking roots etc. Heating at 121 Celsius for >30 minutes is enough to denature it (a microwave oven >might work).
