GMS Labs

GMS Labs - Soil Analysis

GMS Labs offers a complete range of analysis. Today's progressive farmer needs more than just numbers, they rely on comprehensive results, data and analysis across a full spectrum of analytical needs. GMS Labs offer testing in the following areas:

  • Fertility: To grow a bumper crop good fertility is vital. At GMS Labs we put our emphasis on providing you the most accurate results possible.
  • PSNT: Pre-sidedress Nitrate Test, the best test to verify Nitrogen needs for your corn crop.
  • Water GMS Lab offers livestock operator’s analysis of Perimeter tile as required in Illinois (Livestock Management Facilities Act 900.511). If you have a LF number associated with your operation, call to see how we can help you with compliance.
  • Manure: Livestock producers have realized that manure is a valuable commodity and need to understand the value of the material they are applying to their production fields.
  • Nematodes: Soybean Cyst Nematodes are only one of thousands of microscopic worms that can only be seen under high powered microscopes. We can help prevent lost dollars.
  • Radium: This is a special test done mostly by Municipalities to meet EPA Regulations.
  • Heavy Metals: Heavy metal analysis has been increasing over the past few years as gardeners become aware of the potential hazards that may be lurking in the soil of their gardens. Municipalities trust GMS Lab with handling the analysis for land application of filter cake (sludge).
  • Plant Tissue: Whether we are checking corn leaf or potato petioles, the process is the same. We check the growing plant for signs of nutritional deficiency. This analysis allows time for foliar application if necessary; or adjustment in fertility programs. Stalk nitrate, on the other hand, is a post yield check to assess the usage, or over usage of Nitrogen.
  • GMS Labs also offers the SoilBiotics Soil Testing Program. This is a soil analysis that aids in determining pre-plant and side-dress fertilization requirements. It was created by GMS and SoilBiotics with certain criteria to provide an understanding of the crop production capabilities of each field in terms of salinity, soil type, water holding capacity, percolation, and much more!

SoilBiotics provides a comprehensive line of non-toxic conventional and organic plant growth systems. The SoilBiotics Growth Systems are based on improving soil structure, reducing water usage, and increasing the plants ability to metabolize nutrients. SoilBiotics is an industry leader in specialty inputs for commercial agriculture, commercial/ residential gardening, turf/grasses and more.

SoilBiotics Growth Systems, (Conventional and Organic), utilize naturally occurring humic matter or humates, which were formed through the chemical and biological humification of plant and animal matter over millions of years. Humates are recognized by many in the sustainable agriculture movement as one of the most productive inputs available to growers. They have the ability to chemically bond with nutrients in the soil for increased absorption by the plant. In addition, they increase the permeability of plant cells which has been shown to both increase nutrient uptake and decrease stress on plants throughout the growing season. The overall effect is substantially increased yields.

SoilBiotics also offers its Specialty Products line, which include a variety of microbial products, nitrogen maintenance aids, plant foods, and other products. Some are certified for Organic use by OMRI, but can also be used in Conventional programs. Some are for Conventional use only. These products have been specially designed to complement SoilBiotics Growth Systems.
