Our Indian government has recently introduced a programme called BGFP. Earlier the programme by the MNRE ( Ministry of new and renewable energy ) was entirely based on the renewable energy aspect and financial assistance was based on expenditure incurred on renewable energy portion. The Bio-fertilizer aspect was totally excluded for the financial assistance.
The financial analysis shows the biogas and fertilizer contribute equally to the return on investment. The revenue from the biogas portion is regular. However for bio-fertilizer sale one has to wait for 2 sowing seasons in a year. That introduces a problem of storage as well maintaining the quality during the this period. Although bio=fertilizer revenue looks more attractive it does not happen in practice. Is there some method of storage and value addition to make this stream more attractive ?

Regarding macro-nutrient (NPK) comparison with inorganics, biol will generally have lower percentages, but a much high percentage of the nutrients are in a form that is available for plant up-take. Another factor that allows us to have IMPROVED harvests with biol over chemical fertilizers in the first year is that soil with constant chemical fertilizer use us essentially sterile, without a healthy biological activity that converts soil nutrients into forms that plants can utilize (Dr. Karve of this list has argued on various occations that ALL soils have all the nutrients necessary for healthy plant growth, and it is just a matter of have the biological activity necessary to convert the minerals to forms that plants can use). When we add the biol, the bacteria in the biol and the bacteria in the soil we activate begin to convert macro and micro nutrients that have accumulated in the soil, so the plants get a large boost. We feel that NPK is a very dated way to look at fertilization of soils, and biol has benefits that include: micro-nutrients, enzymes, amino acids, active biological components, useful macro-nutrients, among other things. These days, the fertilizer benefits of small digesters is the driving force behind our program, with the gas as interesting bonus, whereas the program started with the reverse idea.

"All soils have all the nutrients necessary for healthy plant growth" holds good only when the surface top layer (12 inches) is with some flora fauna and the soil is not overdrawn. Now a days we witness this situation only in Forest Regions. When an ideal living conditions do exist even the small amount of macro and micro organisms would multiply and even the undigested portion of the digestate will be brought into available form by the microbes. To bring the hidden stored reserves from the bottom layers of the soils (upto 20 feet depth) we need again some species like earthworms, etc. For all this to happen we need some carbonaceous material and which is converted into humus by macro and micro flora and fauna. The humus is an essential link. Building soil reserves is essential so that our future generations will have something to eat . If I am right all the magic is done in the top surface area of the soil in and around the feeder roots (even transmutation). When a human is sick we put him on drip it does not meant we will survive on drip without having balanced food to build blood and muscle, so is the available form of nutrients. The need of the hour is to conserve soils and build reserves that is possible with some amount of carbonaceous materials then and only then as Dr. Karve had said microbes will take care everything. If any system is working anywhere without carbonaceous material we can assume that there are still some reserves in the top soil and some humus. We have almost drawn out reserves and it is high time we build a deposit while drawing limited funds for day to day needs leaving behind some amount of reserve every year. This is the way our forefathers gave us richest soils!
