AI Technical Summary

Technical Problem

Existing seedbed materials, such as polyurethane foam and potting soil, are either difficult to handle due to weight or pose risks from fungi and pests, and separation from plants after growth is time-consuming, leading to environmental burden.

Method used

A soil substitute made from crushed fabric fragments containing cellulose fibers, which are lightweight, easy to handle, and facilitate transplanting, with optional biodegradability for direct incorporation into soil.

Benefits of technology

The cellulose-based fabric fragments provide a safe, easy-to-handle seedbed that prevents fungal and pest issues, allows easy transplanting, and reduces environmental impact by decomposing in soil.

Abstract

This invention provides a soil substitute that can be used as a seedbed or similar substrate, is lightweight and easy to handle, and facilitates easy transplanting into soil. [Solution] A soil substitute material comprising an aggregate of fabric fragments obtained by crushing a fabric containing cellulose fibers, wherein the fabric fragments contain 50% by mass or more of cellulose fibers, and the aggregate of fabric fragments satisfies at least one of the following (i) and (ii). (i) When the fabric is passed through a sieve having a 7mm x 7mm square mesh, the fabric pieces remaining on the sieve account for 30% or more by mass of the aggregate of fabric pieces. (ii) When the material is passed through a sieve having a 3mm x 3mm square mesh, the fabric fragments remaining on the sieve account for 60% or more by mass of the soil substitute material.
