Promote Healthier Ecosystems With the Right Compost for Soil Enrichment

Compost testing is a crucial process that evaluates the quality and nutrient content of compost, a nutrient-rich soil amendment derived from organic waste. It involves analyzing the nutrient levels, pH balance, potential contaminants, and suitability for various applications. Compost testing evaluates the concentrations of essential nutrients like nitrogen, phosphorus, and potassium (NPK), guiding users in determining the effectiveness of compost in enriching soil fertility. It measures pH to ensure the compost aligns with the preferred pH range of target plants. The percentage of organic matter in compost determines its ability to improve soil structure, water retention, and nutrient-holding capacity. Contaminant screening identifies harmful elements that could affect soil health or human safety. The carbon-to-nitrogen ratio is crucial for efficient compost decomposition.
