A coir pellet has coconut pith mixed with at least one other material, and binder mixed into the coconut pith, wherein the coconut pith, at least one other material and the binder are compressed at a ratio of at least 3:1. A method of producing coir pellets includes conditioning coconut pith and at least one other material to produce conditioned material, first compressing the conditioned material to produce pellets of a first size at a first compression ratio, at least a second compressing the pellets of a first sized to produce pellets of at least a second size at a second compression ratio, wherein the second size is smaller than the first size, and the second compression ratio is higher than the first compression ratio, polishing the pellets of at least a second size to produce polished pellets, and drying the polished pellets to produce the coir pellets.

Coir plugs have spherical plugs of coir pith having a diameter in the range of 1 to 3 inches having a seam between two halves of the plug, and indentations in a surface of the plugs, configured to receive a seed. A method of producing coir plugs includes at least one compressing of coir material using opposed half ball cup cylinders to produce spherical plugs having a diameter in the range of 1 to 3 inches and a seam between the two halves, and forming an indentation in a surface of the spherical plugs.

The present invention relates to a rice seedling substrate and a preparation method thereof, which is of the technical field of rice planting. The rice seedling substrate according to the invention was prepared from the raw materials includes the following by volume: 40-60% of dredging sediment, 30-50% of vegetable straw, and 10-30% of hickory shell. The rice seedling substrate according to the invention can not only turn waste into treasure to improve the recycling rate of sediment and agricultural and forestry waste resources, but also save the limited cultivated soils, reduce the production cost of rice seedling substrate, and promote the healthy and sustainable development of rice planting. Therefore, The inventive substrate has significant benefits in terms of economics, sociology and ecology.

A permeable floating concrete vessel for creating floating aquatic habitats is disclosed. The vessel includes an interior space to hold growth material and a plant. The vessels includes one or more channels so a root of the plant can extend through the channel and into a body of water in which the vessel is secured. The vessel is made from a buoyant material, such as water-permeable concrete material. In an exemplary embodiment the water-permeable concrete material includes a mixture of cement, glass microspheres, expanded glass aggregate, and microfibers. Two or more vessels may be connected together via a connecting member to form an array of the vessels.
