Soil Testing is simple: pull soil samples, complete our Soil Testing Form, then ship labeled samples, the completed form and your payment for testing directly to CSI.


CSI tests both domestic and international soils. CSI is a USDA approved lab for receiving 'restricted soils' from the US and abroad. In January of 2014 new regulations for the actual shipment of soil to CSI came into effect for both International and US restricted soils. "Soil must be in a securely closed, watertight container (test tube, vial, jar, bag, etc.) which must be enclosed in a second durable container." Please use standard soil test bags or sealable plastic zip-lock bags. If you can, combine multiple, individually bagged samples, into one large plastic storage bag or a plastic snap cover dish. Please pack them carefully in a sturdy cardboard box for shipping. Do not let them “float” around in the box. If the soil is leaking out of the container, CSI is required by law to quarantine your sample, and call a USDA APHIS inspector and follow their instructions. This could mean that your sample may be destroyed rather than tested.

International soil samples (except Canada) have two more requirements. One, boxes of international soil samples must include a copy of CSI's  International Soil Certificate. Please print certificate and included it with shipment. Second you must affix a "Black and White USDA Label" on your shipping container. Contact CSI by phone, fax or email and we will email or fax you  a bar-coded & numbered label that is good for one box of soil.   Failure to have the Black & White label and the soil permit papers may mean that your soil sample will be destroyed at the border. Sorry for any inconvenience, but current world situations prompted our USDA to “tighten” the rules.

CATION EXCHANGE TEST (CEC):  A standard extraction used by most modern laboratories that is assumed to measure the total nutrients available for agronomic purposes.  These readings help to define your soil and show what is missing according to sustainable agronomy practices. [Based on the Albrecht Model.]  This test will not show what is actually available as does the LaMotte Test above and the readings may differ greatly.  The differences reflect the lack of biological activity and the potential improvement possible. Sample CSI Soil Test results.


LaMotte TEST: A mild soil extraction that has been shown to approximate the extracting ability of plant root exudates.  Therefore, the readings found are considered to be a good indication of the effective or useful levels of fertility available to your crop.  Experience has shown that the LaMotte readings will increase as the biological activity of your soil increases.

CARBON TEST:  In today's Political climate there is  talk about paying the farmer for sequestering carbon from the atmosphere to the soil. Biological growers know that by increasing their soil carbon levels - Organic Matter/Humus - they realize an increase in microbial life as well as soil water holding capacity. This combustion test, performed by a Carbon Analyzer, measures the percentage of C in the soil. Establish your baseline now for possible future Carbon Credits (sequestration.)


MICRONUTRIENT TESTS: Cobalt is a core element of vitamin B12 and needed by ruminants; Molybdenum is required for the fixation and uptake of nitrogen; Nickel is necessary to create the enzymes necessary to break down natural or manufactured urea into usable nitrogen; Selenium has no known function is soil or plants yet without it higher life forms lack a functional immune system; Silicon contributes to stalk strength, sheen and protection against insects and, with boron, enhances uptake of calcium.


SCANNER TESTS: A scanner is also called a radionic device.  It can detect and measure the low level, subtle energies emitted by all matter.  This enables you to see what is happening at the “Quantum” level without very expensive equipment and procedures.


RECOMMENDATIONS: All recommendations are based on analysis of CEC and LaMotte test data.  The chosen materials are for mineral correction/balance and bio-activation are then checked with the scanner to find the ones with the most resonance with your soil.  Experience has shown that the resonating materials are the ones that will provide the best “bang for the buck” at that given time.  Materials chosen for one year are not always appropriate for the next year.  Recommendations usually don’t include the total amount of N that your soil and plant situations might require as each % of OM is assumed to release 30-40 lb. N per acre.


Please call if you have any questions on the tests appropriate for your situation. We appreciate your business and hope we can work with you on your soil recovery work over an extended period of time.
