Monterey County is one of the most productive agricultural regions in the nation. From cool-climate strawberry fields near Salinas to lettuce rows on the valley floor and wine grape vineyards stretching into Carmel Valley, the diversity of crops here places demanding requirements on soil management. Soil analysis gives growers the objective data they need to make confident decisions about nutrients, pH, and amendments before planting.
What Does Agricultural Soil Testing Measure?
These tests measure the chemical and physical properties of your soil that directly affect crop performance. For Salinas Valley growers, that typically means evaluating plant-available primary nutrients (nitrogen, phosphorus, and potassium), secondary nutrients (calcium, magnesium, and sulfur), micronutrients such as iron, zinc, manganese, and boron, soil pH, electrical conductivity (EC), and trace elements. For strawberry and lettuce production, where nutrient timing is especially critical, even small imbalances can affect a harvest. Testing can also detect salt accumulation, a concern in fields irrigated with reclaimed water across Monterey County.
The Control Laboratory analyzes samples using advanced instruments, including ICP-AES for common metals and ICP mass spectrometry for trace-level element detection. Results meet EPA and USDA guidelines, giving growers and their consultants a reliable foundation for fertilizer programming, lime or gypsum applications, and pre-plant preparation.

- Receive your results report with data ready for fertilizer planning, amendment scheduling, or pre-plant preparation.
Why Soil Testing Matters in the Salinas Valley
The Salinas Valley produces significant shares of the nation's leaf lettuce, strawberries, broccoli, and wine grapes. That production intensity places continuous demands on soil nutrient reserves. Regular soil testing may help growers avoid over-applying fertilizers, reduce input costs, and stay ahead of pH shifts caused by heavy irrigation or repeated amendment use. For certified organic operations, regular analysis can also support program compliance documentation.
Control Laboratory has served California's agricultural community since 1954, building deep familiarity with soil and cropping conditions throughout Monterey County and the broader Central Coast. Find Control Laboratory

Frequently Asked Questions
What Is Agricultural Soil Testing and Why Do I Need It?
Agricultural soil testing is a laboratory analysis of your soil's nutrient levels, pH, and other chemical properties. It helps growers make informed decisions about fertilizer applications, amendments, and crop rotations to protect yield and reduce unnecessary input costs.
How Often Should I Test My Soil in Monterey County?
Most agronomists recommend testing at least once per growing season or before each major crop rotation. In high-intensity production areas like the Salinas Valley, where multiple crops may run on the same acreage annually, more frequent testing helps growers stay ahead of nutrient depletion or salt buildup.
How Long Does It Take to Get Soil Test Results?
Turnaround time varies depending on the analysis package selected. Contact Control Laboratory at (831) 724-5422 or through the contact page for current turnaround times.
How Much Does Agricultural Soil Testing Cost?
Pricing depends on the test package and number of samples submitted. Contact Control Laboratory directly for a quote tailored to your crop type and acreage. Competitive pricing is available for ongoing or high-volume testing programs.
Can I Test Soil for Organic Crop Production Compliance?
Yes. Soil analysis can support documentation needs for certified organic operations by confirming nutrient levels and the absence of restricted inputs. Control Laboratory serves both conventional and organic growers across Monterey County and the Central Coast.
