    A Study of Biopesticides and Biofertilisers in Haryana, India
    Ghayur Alam 2000

    Introduction
    The use of chemical pesticides and fertilisers in Indian agriculture has seen a sharp
    increase in recent years. In some areas, such as Haryana, Punjab and west Uttar
    Pradesh, it has reached alarming levels. The heavy use of these chemicals has already
    caused grave damage to health, ecosystems and ground water. It is therefore increasingly
    urgent that environmentally friendly methods of improving soil fertility and pests and

    I can tell you how to make char out of your burnable organic waste. The simplest device is a top-lit updraft kiln. It consists of a vertical cylinder, having relatively small holes near its base for primary air. You fill the cylindrical body of the kiln with the material to be charred and then light it from the top. Once the fire gets going, you place a lid on the cylinder. There is a chimney built into the lid. The lid does not sit flush on the kiln, but there is a gap between the lid and the kiln. The draft created by the chimney sucks secondary air into the chimney, where it gets mixed with the pyrolysis gas to burn it. The biomass burns downwards, leaving a layer of charcoal on top. As the primary air comes upwards, it meets the burning front which traverses downwards. The burning biomass utilises all the oxygen in the primary air, so that the air going up through the layer of char has only carbon dioxide, carbon monoxide, nitrogen and the pyrolysis gas left in it. As there is no oxygen left in the updraft air, it cannot burn the char that has formed above the burning biomass.The pyrolysis gas and carbon monoxide burn in the chimney, because of the secondary air that is sucked in through the gap between the chimney and the kiln. You have to find out by trial and error, how long it takes to char the material loaded in the kiln. After that much time is over, you remove the lid, and extinguish the fire by sprinkling water over the burning material.

    This particular device is portable and manually operated. There are larger charring kilns, based on the oven and retort process. Prof. Yuri Yudkevich, a Russian scientist, has made them for charring useless material generated by the timber industry in Russia.

    We are already using both types of kilns under field conditions in India for charring agricultural waste as also urban waste.

    We have a video CD that describes the kilns and you can fabricate them by watching the video CD. Our web site www.arti-india.org would show you how to get our CDs by paying us through Pay Pal.

  • Terra Preta and Ants - Rooftop Experiments

    Terra Preta and Ants - Rooftop Experiments
    Dr. Sai Bhaskar Reddy, India, December 13, 2007

    Dear All,
    After the successful field trials in Alkaline soils http://e-alkalinesoilsterrapreta.blogspot.com/ , I have just started second season TP experiments on a small scale on our Roof top in small pots
    http://e-terrapretarooftopexp.blogspot.com/. The charcoal is exclusively from use of Magh-1 woodgas or smoke burner stove
    http://e-smokeburnerstove.blogspot.com/ designed by me. I would like to share some of my immediate observations.

    One day after establishing pots and the seed with soil and charcoal and only soil. I have sowed brinjal seeds in the 6 with charcoal + soil and 6 only soil. To my surprise I saw that in the three control pots the seeds were eaten away by small red ants. The six pots with a mix of about 30% charcoal were untouched by ants. In TP practice the chances of germination of the seed with out any loss to creatures like ants is minimized. I thought this is the first direct benefit of using charcoal. On day two I saw that all the pots without charcoal are with small red ants. There is not a single ant in the pot with charcoal addition.

    Although I love ants, to avoid ants eating away the seeds sown, we could always add some charcoal along with the seeds. Second important application is that in the Vermicompost pits some ants eat away the earthworms to avoid such problem and for value addition to the compost to create a habitat for microbes, we could as well add charcoal.

    From web I learnt that those you want to avoid toxic chemicals are using charcoal and diatomous earth as a repellant for ants. For photographs please see the blog below.

    I would like to know from your experiences what could be the other impacts in using Charcoal to the living things existing in soil.

    Dr. N. Sai Bhaskar Reddy

    The fines of rice hull ash mixed in with stored seeds are very effective in controlling weevils. (Rice hulls have a very high silica content.) The sharp silica structures in the ash scratch the cutinous exoskelton of the first insects to emerge, leaving them to dessicate before they can breed and lay more eggs. (I was taught this in a weekend course by the Tropical Products Insitute, U.K.)

    DE (diatomaceous earth) will do the same because of its silica edges, and is also used for pest control in storing grain. It is also recommended to add DE to compost for the same reason: it is not injurious to beneficials in the process like the digestive tract of worms, but will control certain pests that like to colonize compost
    piles.

    Could it be that the charcoal has similar cystalline structures which keeps the insects away...in fear of being scratched to death...?

    Gerald Van Koeverden vnkvrdn at yahoo.ca

    According to a old research study, the effect of charcoal fines on insects might have nothing to do with it as an abrasive or 'scratchy'medium. This article shows that certain dusts actually absorb the lipoid layer from the exoskelton of bees without any apparent abrasion, resulting in the dehydration of the insect. The results (Table 1) show that all the dusts effected an increase in the rate of water-loss of the dead bees; that the three most effective dusts were silica gel, Almicide and activated charcoal, the common physical property of these materials being their capacity to act as powerful absorbents; that Bentonite and activated charcoal, both soft materials, were more effective than carborundum, which is hard and highly abrasive. These facts again indicate that abrasion is not an important factor in the action of these dusts in disrupting the waterproofing layers, and suggest furthermore that they may act by adsorbing the lipoid material.

    Dear Gerrit
    Thanx for this interesting paper.

    TECHNICAL NOTICE:
    Activated charcoal (from gas mask 300 mesh about 50 micron) is very much different than TP. Activated charcoal is an aggressive - powerful absorbent with specific surface area BET 650-1200 m2/g, while TP is mild with specific surface area BET 25-100 m2/g, As far as I know CALCON Carbon tried to put in activated carbon to soil since long time, but was not successful.

  • Biochar use - Munda Tribals, India

    Munda tribals living in parts of Orissa, Jharkhand and West Bengal states, in India, use biochar for increasing the crop production. They mix charcoal with farm yard manure (pellets of small ruminants / cattle dung) and add to the red lateritic soils which are other wise less fertile. They cultivate vegetables and green salad in the well fenced plots of about 1 acre in size. The biochar is mostly a byproduct from the biomass cook stoves in use (most often three stone stoves / simple clay earth stoves). They have access to wood from the jungles, which is used as fuel.

  • BIOCHAR URINALS

    1. GEO BIOCHAR URINAL - PVC and 2. GEO BIOCHAR URINAL - CLAY

    Biochar / charcoal can be used for tapping the Nitrogen and other useful elements. Simple urinals are designed http://e-biocharurinals.blogspot.com/ for tapping the nitrogen and other useful elements for using as a soil amending material for improving the quality of the soils, increasing crop production, addressing the global warming by reducing the NOx emissions, avoiding artificial fertilizers, keeping the toilets clean and odor free, etc.

    Two sets of prototype Urinals - PVC urinal and Clay pot urinal are designed and being used by GEO.

    The production of fertilizers require lots of energy, in many countries Natural gas is used for producing urea in large quantities. This demand is ever growing and we dont have enough energy to meet the demands. The complex fertilizers are also contributing to alkalinity of the soils.

    From the below information we can see that there is a great potential to tap nitrogen from Urine, as biochar has an affinity to tap nitrogen, using charcoal for tapping the Nitrogen and other elements is a great opportunity to find solutions for many problems. Urine is a great source of Nitrogen, Phosphorous and Potassium

    On highly weathered soils in tropical and subtropical climates, maintenance of soil organic matter is essential to sustain system productivity and avoid rapid soil degradation. But climatic conditions as well as soil characteristics favor the rapid decomposition of organic matter. However, several recent studies indicated that black carbon, the product of incomplete combustion of organic material, could combine characteristics highly beneficial for soil nutrient dynamics with high stability against chemical and microbial breakdown.

    On highly weathered soils in tropical and subtropical climates, maintenance of soil organic matter is essential to sustain system productivity and avoid rapid soil degradation. But climatic conditions as well as soil characteristics favor the rapid decomposition of organic matter. However, several recent studies indicated that black carbon, the product of incomplete combustion of organic material, could combine characteristics highly beneficial for soil nutrient dynamics with high stability against chemical and microbial breakdown. Lasting soil amelioration by incorporation of black carbon from wooden plants was proposed based on the beneficial evidence from “Terra Preta” soils in Western Amazonia. Theoretically, charred crop residues in rice-based systems could serve the same purpose but this hypothesis has never been tested. Within this context, our objectives were to 1) assess possible options for the use of charred rice residues, to 2) test the effect of charred rice residues on important soil fertility parameters and rice growth, and 3) to evaluate the effect and stability of charred rice residues in a variety of rice growing environments.
