In our experience, Compostar is one of the best compost inoculants available.
Developed by a world renowned microbiologist, this inoculant contains multiple strains of aerobic bacteria, fungi, actinomycetes, and other beneficial microbes. Suitable for composting straw, wood chips, food waste, manures and other green matter. Can handle a carbon to nitrogen ratio of up to 50. Use 2-3 oz of dry inoculant/ton (1-2 yd) of composting material. Use more inoculant for hard-to-compost sawdust, needles, hardwoods, leaves or other high lignin materials.
Instructions: To preblend into a liquid, mix compostar with water (do not use chlorinated water) at a rate of 1 part compostar to 15 parts water. Let stand for 12-96 hours.
Starting C:N ratio should not exceed 50:1. When working with high C:N materials, add materials with a low C:N ratio, such as fresh green material or manures. It is best to shred or cut the materials into small sized particles. Moisture within the pile should range between 45-65%.
Apply the liquefied compostar uniformly with the organic wastes to be composted. Place the mixed materials into piles or windrows in a covered area to protect from rain (or cover with a breathable fabric). Ideal height of the pile or windrow is between 60”-84”.
Check pile temperature every few days and when the temperature begins to fall, turn the pile and remoisten with water if necessary. Composting process should take about 4 weeks to finish depending on particle size, C:N ratio of raw materials, moisture and aeration.
Caution: If eye contact should occur, wash with plenty of water. Avoid breathing mist. Do not take internally. Keep out of reach of children.
