Sampling instructions

1. Using a clean bucket and a shovel, collect three samples of compost from different areas of the pile.

2. Break up any clods, remove debris, and thoroughly homogenize together.

3. Take out 2 cups of compost and place into plastic bag and label with a sample ID (i.e., Stevie's front yard), type of test, and order number (found in order confirmation email).

4. Purchase your test on our website and send sample to Alluvial Soil Lab, 201 E Center St, Ste 112 #3083, Anaheim, CA 92805 using any postal carrier of your choice.

Turnaround time is between 7 and 11 business days. Results will be sent via email.

Report comes with write-up and recommendations.

Compost analysis is a comprehensive assessment conducted to evaluate the quality and nutrient content of compost materials. This analysis encompasses a wide range of parameters crucial for understanding compost composition and its suitability for agricultural or horticultural applications. Key parameters include:

  • Nitrogen: Assessing total nitrogen content, including Ammonium Nitrogen and Organic Nitrogen forms.
  • Phosphate and Potash: Essential for promoting root development, flowering, and fruiting.
  • Micronutrients: Boron, Calcium, Copper, Iron, Magnesium, Manganese, Sodium, Sulfur, and Zinc are crucial for enzyme activation and overall plant health.
  • Chloride: Evaluation to avoid toxicity.
  • Carbon-to-Nitrogen (C/N) Ratio: Indicates decomposition stage and nutrient availability.
  • Conductivity: Measures soluble salts, influencing soil salinity and nutrient uptake.
  • Moisture/Total Solids: Determines compost stability and application rates.
  • Organic Matter and Ash: Provide insights into compost quality and nutrient retention capacity.
  • pH Level: Affects nutrient availability and microbial activity within the compost.

Through meticulous analysis of these parameters, compost quality and suitability for agricultural use can be determined, enabling growers to make informed decisions regarding soil fertility management and crop production practices.
