A method for making a growing medium includes a step of combining tree bark and/or wood components together to form an initial composition; heating the initial composition to a temperature greater than about 149 C. under steam in a pressurized vessel; processing the initial composition through a refiner with a plurality of opposing disks to obtain the fibrous growing medium, the refiner separating fibers from each other; wherein the growing medium has total porosity of 88 volume % or more.

Methods of amending soil to improve porosity and reduce compaction are provided. The method includes providing a carpet product. The method further includes separating the carpet product into fiber and granules. The method also includes adding the granules to the soil. The method can also include impacting the carpet product with a rotary impact separator. The method can also include impacting the carpet product with a hammer mill.

Some variations provide an emulsion-colloid system for forming a colloidal barrier material disposed on a substrate, the system comprising a hydrophilic first liquid, an acid, a gelling agent, a hydrophobic second liquid, a plasticizer, and optionally additives, wherein the emulsion-colloid system is characterized by (1) a first instance that is a flowable emulsion above 60 C. and less than the boiling point of the first liquid, and (2) a second instance that is a colloid below 40 C. The emulsion-colloid system is capable of reversible transition, mediated by temperature, between the first instance and the second instance. The disclosed colloidal barrier material provides the functionality of plastic alternatives while removing disadvantages. The disclosed colloidal barrier material reduces labor-intensive application of the barrier, such as the case for covering grain piles with plastic tarps. The disclosed colloidal barrier material also eliminates the need for removal when barrier protection is no longer required.

This invention relates to a polymer composition which is particularly suitable for use in the manufacture of films having a great ability to disintegrate, preferably at low temperatures, which can be used in the mulch film sector.
