Fibergro is produced during the processing of virgin wood pulp into tissue paper. The resulting by-product from this process- Fibergro, consists primarily of short paper fibers and nitrogen. Use of this high organic content, weed-seed free product is a cost effective way to improve soil condition and health. Fibergro has been used on agricultural soils since 1989, and has proven its ability to enhance soil structure, improve soil aggregation, and help minimize soil compaction. Fibergro also serves as a valuable ingredient when added to topsoil by improving organic matter levels and providing a source of slow release nitrogen.
