About Us   

Dellavalle Laboratory, Inc. was founded in 1978 to assist growers in making decisions regarding fertilizer applications, soil management practices and other related agricultural areas. Over the years we have grown into one of the foremost consulting laboratories in California, specializing in analyzing soil, water and plant tissue primarily for environmental and agricultural markets.

We employ Certified Professional Agronomists/Soil Scientists and Crop Advisors with expertise in water usage, soil science and plant nutrition. Our consultants can provide assistance with nutrient management planning, fertilizer recommendations, influent/effluent, fertility/salinity and irrigation management and troubleshooting.

Based in California's San Joaquin Valley, we serve clients throughout California, 11 Western States and many countries. Our analytical methods are appropriate for arid and semi-arid agricultural conditions. University of California research is the basis of consultant information.
