Achieving desired production levels for dairy operations can be challenging, and once achieved maintaining these levels can be difficult. And then achieving consistency and desired production levels with a particular ration, only to find that the inventory of one or more of the forages is quickly running out can be frustrating.

By addressing the possible requirements with respect to potential cow numbers and production levels, a plan can be formulated for the upcoming planting season.  With adequate acreage and reasonable yields, inventory shortages can be avoided and desired rations can be maintained throughout the year.


For forage crops, that remove the whole plant, nutrient removal values can be very high. To maintain soil fertility, it is important to properly account for these removals and adequately replace. Testing manure to determine nutrient credits as applied allows the calculation of additional fertilizer required. Soil testing more frequently for forage fields will monitor fertility trends, and can also identify deficiencies of micronutrients, such as Boron for alfalfa and Zinc for corn.


SGS can provide water analysis for many different operations. Balancing nutrients, pH, and EC based on a raw water test is important for greenhouses, nurseries, and garden centers.

Monitoring and balancing mineral levels in livestock drinking water benefits animal health.

Microbiological testing of irrigation water is often required for food safety purposes.

Water testing packages available include:

  • Greenhouse water and nutrient solution
  • Livestock water suitability
  • Field Crop Irrigation Water
  • Microbiological Testing (e. Coli, Total Colliform, etc.)
