Arvum Plant Labs Chain of Custody FormComplete Soil Analysis | Optimize Organic & Soilless Mixes
Soil analysis is used to understand the plant’s ability to absorb nutrients and to determine optimal irrigation requirements. We also test Coco Fiber, Peat Moss and Composted Forest Material.
This full lab panel covers pH buffer capacity, cation exchange, fertility, and harmful salts so you can craft bespoke amendment plans.
When Should I Test My Soil?
Growers should consider Soil testing:
- With a new batch of soil before filling pots
- Between runs when re‑amending living soil
Soil Analysis Example
- Finding: CEC 11 meq/100 g (low) and K 0.15 % (deficient).
- Action: Add 1 lb/yd³ biochar to boost CEC, top‑dress 3 g/gal sulfate of potash, re‑test after two irrigations.
What To Expect: We will ship the appropriate sample holder and accompanying instructions, along with a prepaid return label, if requested, for sending it back to our facility. Test results will be available within 2 to 3 business days after which one of our Cultivation Advisors will contact you to discuss the next steps.
