Sampling Instructions for BeCrop Test
To ensure the highest accuracy when analyzing your soil microbiome, it's important to follow standardized sampling protocols. Proper collection and handling preserve soil DNA integrity and support accurate analysis of nutrient cycling, disease risk, and stress adaptation.
Step-by-Step Soil Sampling Guide
1. Prepare Tools and Materials
-
Use clean digging tools and wear disposable gloves.
-
Disinfect all equipment between sampling blocks to prevent cross-contamination.
2. Take a Composite Sample
-
Identify a block with the same crop and management history.
-
Collect multiple cores using a “Z” or “W” pattern and mix them together.
-
Depth: 5–15 cm (2–6 inches).
-
Proximity:
-
Fruit crops: 60 cm (24 in) from the trunk
-
Vineyards & super-intensive systems: 30 cm (12 in) from the plant
-
Row crops: in the root zone
-
Important: Avoid sampling for 3 days after heavy rainfall and do not sample directly under drip emitters.
3. Measure and Package Soil
-
BeCrop:
-
Use the coded tube provided by Biome Makers (fill halfway, ~1–3 grams), or
-
Use a sterile labeled bag (~1/4 cup or 10 grams minimum).
-
-
BeCrop+:
-
Use the coded bag and fill to the line (~500 grams / 2 cups), or
-
Use a labeled bag with equivalent volume.
-
Note: A mixing bucket is required for BeCrop+ sampling.
4. Complete Documentation
-
Fill out the BeCrop Submittal Form or Excel metadata sheet.
-
Minimum required fields:
-
Field ID
-
Sample reference
-
Collection date
-
Crop type
-
Coordinates (Latitude/Longitude)
-
Include additional metadata (e.g., soil type, irrigation method) for more comprehensive analysis.
Storage and Shipping Guidelines
-
Ship samples immediately after collection to preserve microbial integrity.
-
Transit Time: Use 1- or 2-day shipping. If samples are in transit for more than 5 cumulative days at room temperature, you must include icepacks.
-
Short-Term Storage: Store samples at 0–6°C (32–48°F) for up to 3 days.
-
Long-Term Storage: Freeze at -20°C (-4°F) if shipping is delayed.
