NOVELTY - Stitch less, heat-sealed, high-density polyethylene (HDPE) substrate-tetra low-density polyethylene (LDPE)-layered, vermicomposting bed (100) constructed of a composite fabric (90), comprises: a main panel (100-1) of the fabric; two side panels (100-2, 100-3); fourteen, inverted U-shaped pockets (80-1 to 80-14); fourteen round, straight, 39 inch long wooden poles; six windows (70-1 to 70-6), made by cutting out respective pre-marked portion from side panels and heat sealing HDPE net; and a drain, cut open in marked portion of the main panel and covered with a HDPE net over the drain opening.    USE - The tetra vermi bed is useful for composting agricultural waste (claimed) into nutrient-rich manure.    ADVANTAGE - The tetra vermi bed: propagates production of worms and yields high-quality manure, which is easy to handle and to economically transport in bags; is easy to install and to dismantle for operation at multiple sites, storing agricultural waste; is an earthworm-friendly, portable and foldable; and is light in weight.    DETAILED DESCRIPTION - Stitch less, heat-sealed, high-density polyethylene (HDPE) substrate-tetra low-density polyethylene (LDPE)-layered, vermicomposting bed (100) constructed of a composite fabric (90), which is made of UV-stabilized, four, hot extrusion coated, LDPE layers, where the four layers are laminated and alternating with UV-stabilized, three, HDPE substrate (woven fabric) layers, comprises: a main panel (100-1) of the composite fabric, admeasuring 16 feet, 9 inchesx 2 feet; two side panels (100-2, 100-3), where each the side panel of the composite fabric admeasures 12 feet, 9 inchesx 2 feet, so that the ultimate size of the tetra vermi bed, made of the seven-layered composite fabric admeasures 12 feet long 4 feet widex 2 feet high, the vermi bed has an internal volumetric capacity to contain 96 cubic feet volume of waste and the ultimate shade of the tetra vermi bed exteriorly is green and interiorly is snow white; fourteen, inverted U-shaped pockets (80-1 to 80-14) made of the seven-layered composite fabric, where each of the pocket is open with inverted U-shaped mouth at bottom end and closed at top end by anchoring by roped end of the side panels or of the main panel; fourteen round, straight, 39 inch long wooden poles, where each of the pole grouted at a pre-marked holes to 18 inches depth below the laid ground surface and projecting above the ground surface to a height of 21 inches; six windows (70-1 to 70-6), made by cutting out respective pre-marked portion from the side panels and heat sealing HDPE net, over the cutout portions with round comers, where each of the window admeasures 8 inchesx 4.5 inches; and a drain, cut open in marked portion of the main panel and covered with a HDPE net over the drain opening, where the drain is resting atop a semi-circularly, cut-open pipe along part length and buried for the remainder length in soil under the drain of the tetra vermi bed, where the drain admeasures 3.5 inchesx 1.5 inches. An INDEPENDENT CLAIM is also included for composting agricultural waste in the tetra vermi bed, comprising: (a) sorting out hard material, including stones and domestic animal dung from partly decomposed agricultural waste and leaching out animal urine from the partly decomposed waste by watering and precipitating out salt to less than 0.5 wt.% level; (b) layering alternately in the tetra vermi bed, the partly decomposed waste and the animal dung each in 6 inch thick layers and repeating the layering process till the tetra vermi bed is almost filled to brim or alternatively filling completely with animal dung; (c) sprinkling water in fine spray over the contents of the tetra vermi bed till heat of the contents is positively removed and the contents of the tetra vermi bed are cooled and humidity initially is 70-80 wt.%; (d) checking settling down of the contents after sprinkling water and adding a layer of animal dung till the contents reach the 2 feet height of the tetra vermi bed; (e) measuring periodically temperature of the contents and maintaining it to 25-35 degrees C and maintaining moisture to adequate levels; (f) periodically checking pH value and maintaining it at 5-9; (g) adding calcium carbonate to the contents to raise pH to 5-9 level or adding peat moss to the contents to lower pH to the required 5-9 level, where ideal pH is 7.5 indicating slightly alkaline nature, favorable for reproduction of worms; (h) making 3-4 inches deep basins into the contents along all sides of the tetra vermi bed, after it is sufficiently cooled down and the water content comes down to 20-30 wt.% so as the waste to become sufficiently moist and porous for free movement of earthworms; (i) adding earthworms to the basins, allowing them to mix with the contents and closing the basins; (j) repeating the process after three days, as described in step (h) above but to add proper feed for worms; (k) frequently watering the contents for maintaining the porousness of the decomposed waste to facilitate free movement of worms; (l) allowing earthworms for 2 months to work on the partly-decomposed agricultural waste; (m) collecting vermi wash liquid in the container placed in the pit; (n) periodically inspecting the vermi wash liquid, earthworms and the tetra vermi bed and monitoring temperature; (o) gathering the produced manure, after 40 days, from all sides of the tetra vermi bed and stacking it in a pile, thus leaving earthworms at bottom of the tetra vermi bed; (p) sieving the produced manure and packing it in bags; (q) sampling the packed manure for inspection for quality check; and (r) re-using earthworms segregated from the produced manure in following manure production batches.
