>Features
>This method uses known and successful organic farming
>practices and has been suggested by Mr.Gopal Sane of
>Samrudhhi. It also has empirical evidence on sure shot
>success achieved in stabilising biosolids wastes in a
>cold composting process, not known or experienced in
>any alternative methods such as vermi compost/culture,
>windrows, NADEP method.
>
>It allows early period in situ incubation, nursery of
>seeds/seedlings in a shelter, which offers moisture
>and rich soil/nutrient conditions with biodynamic
>activity normally associated with healthy soils.
>
>Tree shelter construction
>Each tree shelter can be made of brick with cement
>mortar jointing or innovatively make use of UV
>stabilised FRP enclosure. With bricks, the structure
>can be square/rectangular shape. It should be 1 to 1.5
>metre deep/height and sides of 1 metre each. So the
>enclosed space will roughly have a volume of 1 cubic
>metre and surface area of 1 sq metre or roughly 10 sq
>feet.
>
>FRP enclosure can be circular and of a shape like this:
>(The sketch can be e mailed in a Word file on request)
>
>The top will be a smaller circle than the bottom. The
>top circle can be about 3.5 to 4 ft (1 Metre) diameter
>and the bottom circle between 5.5 to 6 feet (1.5 to 2
>metre) diameter. The conical shape will have a height
>of 3.5 to 5 feet (I to 1.5 meter) in height.
>Anchoring flaps can be 1 to 2 feet in length and about
>6 inches breadth. It can be constructed by being cast
>on moulds into a circular shape along with flaps. For
>mass production for a large number of tree shelters
>this offers the best method.
>
>The tree shelter also protects the sapling in early
>years until the roots are able to penetrate deeper
>into sub soil layers. In later years, it will anchor
>the sapling until the root system is well developed.
>It need not be removed and therefore the FRP enclosure
>can be left in place permanently.
>
>Cheaper tree shelters can be made of rock and stone
>pieces, discarded automotive tyres, rubble from
>quarries, demolitions, depending upon funds
>availability.
>
>Seeds can be sown direct since the stabilised
>biosolids encourage easy germination or can be
>transplanted after raising seedlings in poly bags
>filled with soil and stabilised biosolids. Care must
>be taken to centre the sapling, so that the tree does
>not have to strain the tree shelter in later years,
>when its girth has grown. Drainage holes are required
>to remove excess water, especially rainwater that may
>have excess nitrates, which will overload the
>biosanitiser. If the ground is somewhat porous,
>allowing excess water to percolate down, then the
>drainage holes are not required. Seeds or seedlings
>are better planted after the enclosure if nearly full
>with stabilised bio solid wastes. This can be after 6
>months to 1 year after the loading of wastes starts.
>
>Cattle/goat guard
>The treee shelter has no provision for a cover to
>protect saplings from grazing cattle, goats, which are
>a constant menace to tree plantations in India.This
>can be done by wire mesh like structure made with FRP
>or mild steel wires, welded or woven, which can be
>bolted to the top of the FRP tree shelter. This will
>ensure that the main stem grows to a height which
>places it beyond the reach of grazing animals, from
>where the branches will spread.
>
>The alternative of pits
>Tree plantation is also done in rocky areas by digging
>out rocks with equipments like bulldozer and then
>filling up the pit with top soil and manure. While
>this can also be attempted when bio sanitiser treated
>wastes can be applied to the pit or allowed to
>stabilise (not decompose ) in situ on the pit,
>experiments show that when treating bio solid wastes,
>the bins are the best alternative, since this allows
>concentration of bio sanitiser effect by limiting the
>micro environment to the bin and isolation of external
>effects from the soil. Since excess nitrates are an
>endemic phenomena all over the world, the seepage of
>nitrates and other influences from surounding soils is
>minimised with above tree shelter construction, which
>is not possible in a pit. Consequently the efficiency
>of the biosanitiser for the given task is optmised
>since it is not overloaded with shock loads of excess
>nitrates and other toxic elements. The criteria to
>apply is that the soil should not experience water
>logging, in which case rain water which normally
>carries excess nitrates will overload the bio
>sanitiser.
>
>Pits can therefore be used and economically will be a
>better alternative if the soil is naturally well
>drained without water logging and in land, which has a
>slope, such as hilly areas. Pits used for
>stabilisation of biosolids have worked very well,
>where the soil is well drained. Hence this methodology
>can be extended to tree plantation also where the
>terrain permits.
>
>Maintenance
>The watering of these tree saplings requires attention
>for several years particularly in hot summer months.
>Wastewater from kitchen, etc can be used if water is
>scarce. Even sewage water can be used in extreme
>situations, although the ability to stabilise
>pathogens requires experimentation trials. If
>possible, effluent waters can be treated with bio
>sanitiser and then used for irrigation.
>
>Loading of wastes
>The current strength of biosanitiser is roughly 10
>grams to handle a daily load of 5 kg bio solids waste,
>applied on a surface area of 1 sq metre or roughly 10
>sq feet. In cities this bio solid waste is normally
>generated by two families - mostly from left over food
>wastes, kitchen wastes. Bio sanitiser can handle food
>wastes of vegetarian and non-vegetarian origin,
>including bone and animal body tissues, feathers and
>other animal tissues. It will also enable pathogen
>stabilisation by removing excess nitrates from its
>environmental vicinity, where the bio solids are
>contained. Some loose soil can be interspersed with
>the wastes to provide some soil for the tree. There is
>no fixed ratio and it can be roughly on a ratio of 1
>parts soil to 3 parts bio solids waste after volume
>reduction. Plants, shrubs have been grown successfully
>in 100% stabilised bio solid wastes in terrace gardens.
>
>Each tree shelter can take maximum of 5 kg bio solid
>waste spread evenly on the surface. The Vermi++ will
>stay permanently at the bottom. The waste undergoes
>size reduction - about 75% as is normal for MSW.
>Horticultural and farmyard wastes can also be added.
>If kitchen wastes are applied in isolation without
>other cellulosic materials of horticulture and
>agriculture, the compost can be stabilised to a safe
>Ph level by application of commonly available rock
>dust sprinkled at intervals as intervening layers. The
>composting process is cold and will not raise
>temperatures and yet pathogen activity will be
>arrested by removal of nitrates which offer sustenance
>to gram negative bacteria and viruses, which play the
>role of scavengers in nature to remove excess
>nitrates, as per Dr Uday Bhawalkar.
>
>This methodology does not include wastes from human
>and animal excreta streams, or washing, bathing
>effluents. The wastes from these streams can also be
>processed but will require a different set of
>applications. Such processing will enable recycle
>wastewater in local situations including ground water
>recharge. Even septic tank overflows can be used for
>irrigation.
>
>Bio sanitiser application
>Normally a 10-gram packet will be enough for two tree
>shelters of above dimensions and waste loading
>capacity. If very bad quality sewage water is to be
>used then 1 packet can be tried per tree shelter. A
>better method would be to treat the effluent
>separately with bio sanitisers and then use the
>treated water for watering the saplings.
>
>Previous applications in tree plantation
>Quote from a press report dated 22 July 2004.
>"Another major offshoot which is described as the
>"by-product" of this project is making a Enviro Road
>at the oldest and popular D.N Road. This exercise will
>involve plotting tyre-planters of various sizes that
>will serve as a homogeneous sculpture with seasonal
>flowers and green. The section of the divider wall
>near the Times of India building has been greened with
>half tyre planters on a single colour base. Further,
>Lagestromia Thorelli will be planted at every 20 ft
>making a green cover of 60 trees to line the road. The
>foot over bridge from CST will have cascading white
>bougainvillaeas on its sides! Note: Shanta
>Chatterji, of Clean Air Island, has used Vermi++
>Biosanitizer for this project funded by EU. Mrs.
>Aparna(Varsha) Inamdar actually made the visits. She
>was also invited to Ireland to start a project in
>Ireland in subzero conditions two years back and it
>was very successful. The Irish and British experts
>visited Mumbai and Pune recently to see all the

>Choice of trees
>Best decided by local ecology. Native species offer
>the first choice. This is especially so where the
>ground is rocky and water tables are low and support
>only selected species of trees. For other plantations,
>such as for raising oil seed bearing trees like
>Pongamia, Jatropha, these planters can be used. For
>normal terrain, planters can be done away with but bio
>solid wastes can be applied in a similar manner.
>Tissue culture can be tried for propagation of
>scarcely available species, which are most suited.
>
>Benefits
>These projects can create biomass for raising goats,
>cattle, silk worms, or oil-bearing seeds like Pongamia
>and Jatropha for use in bio diesel production.
>
>Fruit bearing tress also can be cultivated with this
>technique. In hilly areas the tree shelter will help
>anchor trees to difficult terrain in early years. Can
>be used to prevent landslides in hilly areas, which
>have loose soil conditions.
>
>The surrounding microclimate will improve through
>increased greenery offered by the tree cover and
>ground water tables and its water quality will see
>improvement gradually, due to restoration of bio
>dynamic activity in the soil. Deep burrowing
>earthworms will appear and help harvest rainwater.
>
>Funding
>Preferably with local participation and involvement.
>This will ensure success of the project as a community
>initiative in common and waste lands development.
