The penetrometer is a gauged probe used to measure the level of compaction at various levels within the soil. As soil becomes more compacted, it loses its ability to absorb and retain moisture. The soil pressure in the aerobic zone (with oxygen) should not exceed 300 PSI (pounds per square inch). This is where the feeder roots of most plants exist and they are unable to penetrate higher levels of pressure. The anaerobic zone (without oxygen) is where the soil loses its ability to drain water and can no longer pull fresh oxygen in.
A refractometer measures the Brix level (sugar content) of a substance. The VeeGee refractometer is a simple fuel gauge for your crop. It is durable and has an all metal design. By looking through the eye piece you will notice that the refractometer has a high quality optical glass prism that helps make your reading as clear as possible. A rubber grip that is dimpled helps ensure a simple external cleanup.
The Milwaukee MW302 is a cost effective and reliable meter used for measuring electroconductivity (EC) in the soil. A 'slurry' mixture is required for this unit, which consists of equal part of soil mixed with distilled or deionized water. The MW302 comes with a sturdy carrying case, calibration solutions and a measuring cup for mixing.
The Spectrum FieldScout is a direct soil meter used for measuring electroconductivity. This feature offers accuracy and convenience. The FieldScout has a patented paired sensor tip which provides maximum soil-sensor contact and higher accuracy and automatic temperature compensation. This meter includes a sturdy carrying case and calibration solution.
The Back To Your Roots Get Start Kit is a must have for all producers. This package includes a VeeGee refractometer to measure Brix (sucrose production) levels, and a Milwaukee MW302 electroconductivity (EC) meter to monitor the conductivity within the soil. These are simple instruments to use, and they provide valuable information about the health and productivity of the soil and the crop growing there.

The Lamotte Nitrogen kit is an economical and efficient way for producers to test the level of nitrogen in the soil. Within less than an hour, the results are available to enable more informed choices for fertility needs.
This line of combination soil analysis outfits offers the finest visual color matching system available to today's agronomist. Technically advanced reagent systems and unique extraction procedures based on the Mehlich I extraction provide fast, simple and extremely accurate soil testing.
Both Model AST outfits are furnished in rugged, lightweight carrying cases with components securely mounted in removable foam-lined trays. This format permits easy conversion from an in-store lab to service in the field. Each kit includes simplified and complete instructions, a pad of soil analysis report forms, instructions for collecting representative soil samples and a copy of the LaMotte Soil Handbook. This handbook contains charts with data on the nutrient needs of various crops. It also contains general information on using soil test results to determine actual lime and fertilizer requirements for optimal plant growth.
This test kit is safe, easy to use and cost effective. Each kit contains non-hazardous TesTabs and everything that is required to perform up to fifty tests each for nitrogen, phosphorous and potassium levels.
