CALIFORNIA GROWERS LABORATORY, INC.

Plant, Soil, Water, Nematode Testing & Recommendations, EST 1979


What's New?



We would like to announce some personnel changes at California Growers Laboratory, Inc. Roger P. Kerneur has joined the team as a consultant with 25 years of experience, specializing in Plant Science and Viticulture. Our new consultants will continue to maintain the high quality performance of our laboratory, which is always under the professional expertise of Mr. Kamal Sakoury.



Who are We?



We are your complete agricultural testing laboratory serving valley growers since 1979. We utilize the same analytical equipment and procedures used by the University of California in developing the optimum ranges for the diverse crops grown in California.



Soil, plant and water analyses are the farmer's best guide to wise and efficient use of fertilizers and soil amendments. The cost of soil and tissue programs are far less than the cost of loss due to nutrient deficiencies or use of unneeded fertilizers. It is integral to choose a lab that does high quality work, which is based on accurate sampling, analysis and strict quality control. California Growers Lab. uses quality control samples from the National Institute of Standards, Washington D.C., and the Western State Proficiency Testing Program to insure the quality of your analysis.



California Growers Laboratory has soil and tissue permits from the USDA (Permit # -S-2852), which allows us to receive samples from anywhere in the world. We provide recommendations and crop consulting along with nematode testing and water analysis for agricultural suitability.

5. Nematode Analysis: Root Knot, Dagger (XI), Dagger (XA), Ring, Pin, Citrus, Etc..

Any portion of these analyses are also available upon request.

Analysis Include:

1. Data Sheet with results

2. Color tissue history graph- a colorful four year representation of the data. The graph will enable you to interpret data with ease and aid in making cropping decisions.

3. Complete recommendation with crop consultaion.    

Sample results will be sent to you as a hard copy through the mail, but results can also be sent to you via FAX or E-mail. E-mailed results will give you direct access to your results through the computer.

Soil Sampling Procedure:

0-3' Profiles- These samples are taken throughout the year, but are generally taken in the fall on established permanent crops. They are used to set up soil amendments and fertilizer programs for the upcoming year. One sample location should be taken each twenty acres. Within this location, two separate depths should be taken. A composite sample from 0-18" and another composite sample taken from 18-36" should be adequate for a 20 acre block. The two samples will allow for a comparison between the two depths, since most of the roots of permanent crops are found within three feet of the soil surface. Many significant soil variations can be found within these depths, so comparison of the two depths can aid in making proper recommendations on soil amendments. Separate samples should be taken in areas of the field with different soil textures, past cropping patterns or any other variation that may affect nutrient levels or soil chemistry.

Soil samples are to be placed in a bag and labeled as to field location, type of crop, depth and any other pertinent data that may be necessary. About 1-2 lbs of soil should be sufficient. This is usually around the size of the brown lunch bags, filled half full. Samples should be taken to the laboratory for analysis as soon as possible.

Tissue Sampling Procedure:

Tissue samples are to be placed in sample bags and labeled as to field location, date sampled, growth stage, appearance of crop and any other pertinent data. While in transport to the laboratory, the samples should be kept as cool as possible and out of the sun.

Locations of Samples:

1. Samples should be taken 20-40 acre blocks.

2. Tree & Vines-Set up sampling stations (6 rows with 10 trees or vines per row) in each block. Collect 40-60 leaves or petioles (about 1-2 leaves or petioles per plant) which represents the vineyard or orchard. Care should be taken to begin at least 60 feet from the edge of a field before you begin sampling. Cuts, fill and significantly different soil types or growth patterns of the plants should be sampled separately. Once desired location is identified, the field should be sampled in the same location at future sampling dates.

3. Different crops require different sampling dates, along with different parts of the plant. Below is a list of crops, the plant part that must be sampled, and the time of year that the sample should be taken.
