How long will KELP FIBER remain in the soil?
The perlite that composes half the bulk of KELP FIBER is inorganic and will continue to aid in the percolation of air and water through the soil for many years, while the alginic acid that is responsible for the moisture holding capacity of KELP FIBER reportedly lasts seven years in the soil. The nutrients in KELP FIBER are slowly released, as in time release fertilizers, over a two year period.
