摘要 |
An economically efficient agricultural pellet of enhanced structural integrity comprises up to about 15% by weight of non-crystalline silica fibers blended with one or more other nutrient substances, such as calcium silicate and/or magnesium sulfite, such that the silica fibers to form an interlaced matrix dispersed throughout the body of the pellet. Fragmentation agent(s) and/or soil amendments may also be included. The silica fiber matrix provides both structural reinforcement and a source of bio-available silicon. In embodiments including calcium silicate, additional structural integrity is gained through pozzolonic bonding.
