<div>Dear Mr. Allison,</div>
<div>organic acids and even sugar is directly taken up by plants only if the plants are raised under totally sterile conditions, as in the case of plant tissue culture. If the plants are growing in ordinary, non-sterilized soil, the organic matter applied to the soil would be eaten up by the microbes in the soil and practically nothing would be left for the plants. There are normally about a hundred million microbes in a gram of field soil. None of them conducts photosynthesis and any organic matter applied to the soil is immediately scavenged by them. In that respect, they are much more efficient than the plants. <br>
Yours</div>
<div>A.D.Karve<br></div>

Anything that passes through a microbes gut has to be very refined, to say the least. These tiny creatures convert organic matter into colloidal materials ideally suited to direct ingestion by plantlife -directly.<br>Admittedly, extraneous materials such as fiber and other debris needs to be excluded. The end result being fulvic and humic acids, the life giving elements of plants and many other creatures.<br>
The gas generated by bio-conversion is but a bonus. The resultant fluid is the life force for plants. It is the basis for sustainable agriculture.<br>What goes into a bio-reactor is derived from plant matter. What comes out is ideally suited to plant-life.<br>

would want to share yesterday's photos with you (sorry the dates on the<br>photos are for Feb 14th 2012 - my camera seems to be crazy lately!!).<br><br>This is a farm 40 km away from Kampala, a long Hoima Masindi road. The farm<br>
has over 600 dairy cows, 250 of these are in a single facility that I was<br>able to visit. All the dung from this facility is moved into a massive tank,<br>(this is the biggest cow dung collection point I have come across!! It is<br>
heaven for a biogas gig!). The dungs needs to be converted to Electricity.<br><br>I will focus on the assessment for biogas, however, I do not much experience<br>with these larger biogas systems. Are you in position to advise? Your<br>
experience will be fantastic. Let me know what you think.<br><br>I am off for now, I will be back.<br><br>Kind regards<br><br>Vianney Tumwesige<br>Director-Green Heat (U) Ltd<br>P.O. Box 10235<br>Kampala-Uganda<br>+256 (0) 71 <tel:%2B256%20%280%29%2071%<u></u>20237%209889> 237 9889<br>
