The following raw amendments get homogeneously mixed with the compost in small batches and is then matured (a.k.a. “cooked“) for 21 days or more.
Macro-nutrients
Nitrogen: Alfalfa Meal and Blood Meal.
Phosphorus: Bone Meal and Soft Rock Phosphate
Calcium: Gypsum and Calcitic Lime (pH Buffer)
Sulfur: Gypsum
Potassium and Magnesium: They do not add any additional potassium or magnesium as the compost provides sufficient amounts.
Micro-nutrients
Trace Elements: Basalt Rock Dust and Kelp Meal
If a soil lab test indicates that any other micro-nutrients such as Manganese, Copper, Iron, Zinc or Boron are below target levels then we will add trace amounts to boost these elements.
Silica: Diatomaceous Earth
Additionally they also add a little Insect Frass for chitin, Malted Barley for enzymes, Humic Acid to chelate the nutrients and Synergistic Microorganisms to boost the microbial populations.
