How much does soil testing cost?
Prices for one sample range from $15 for pH and salinity only, to $74 for basic fertility with fertilization recommendations, up to $187 for fertility, texture and suitability with planting recommendations. Please note these prices are for work by our Santa Clara office and might vary slightly at our other offices. top

Can a representative from the Laboratory take the sample for me?
Yes. There is an additional onsite fee and travel fee. top

What is your normal turnaround time?
5-7 working days after the sample is received for data with a report, or 3-4 days for data only. Expedited service is available at an additional cost. For data and report with recommendations a rush of 2-3 days would be normal cost plus 75-80% and a hurry of 4 days would be normal cost plus 25-30%. top

How much soil do you need?
About one quart. Two cups bare minimum. top

How deep do I take a soil sample?
Deep enough to represent the zone of feeder root activity. top

I'm putting in a new landscape. What test package do you suggest?
Try the A05, A17 or A01 test. top

My yard is already landscaped. What test would help determine the best maintenance fertilization program?
Try the A17 or A01. top

My plants are yellowing. What test would help me?
Depending on the pattern of yellowing, try the A01, A17 or P01 (disease diagnosis). For nursery or agricultural clients, A66 leaf analysis is also suggested. top

There's a spot in my yard where nothing grows.
Try the A17 or P01. top

Can you test leaves?
Yes, although nutrient testing is best-suited for nurseries, orchards and row crops where several of the same plants can be represented by one sample. top

Do you test well water?
Yes. The A71 checks suitability of the water for irrigation purposes. top

Can you check for diseases?
Yes, mainly from symptomatic root, crown or branch tissue samples from declining, and not totally dead, plants. It is usually best to call first to get sampling instructions. top

Can you test for organic contaminants, heavy metals or pesticides?
No. Referrals for other labs can be provided. top

Is your test guaranteed to determine the problem with my plants?
No. Cultural factors not covered in the testing might be involved. A soil test can at least determine if soil chemistry or fertility is a limiting factor. The written report may offer suggestion of further inquiry. top
