United Soils, Inc. understands the need for timely and accurate results, and it starts with collecting meaningful samples. Our field technicians follow strict field mapping & sample collection protocol to assure the lab receives the most representative field samples possible.
USI uses GPS mapping technology to generate field maps and their associated grid / core sample locations. Cores are collected and composited surrounding the predetermined sampling site.
Results from the soil analysis are processed with GIS data-handling software to create field and nutrition-based maps.
This approach provides the most efficient and accurate results for our customers.
USI pulls and tests samples based on our customer requests. Our website's online order form starts the process (USI-Works).
We pride ourselves on our customer service and strive to achieve the below goals for each and every job:
• Fast
• Affordable
• Predictive
• Reproducible
• Widely Applicable
• Track Changes in Fertility
United Soils Inc. suggests following the provided guide below when obtaining
plant tissue samples for analysis. Results of the analysis will determine
whether problems in plant development are due to nutritional factors.
Precise results are possible only when carefully selected plant material is submitted for analysis. Accurate sampling requires that select parts of a
plant are collected at certain stages of plant development. A plant's nutritional
condition differs for each variety, stage of development and growing area. It is recommended to select plant tissue representative of a particular variety and growing area. Place samples in un-lined paper bags.
What Not to Sample: Diseased or dead plant material; plant tissue damaged
by insects and/or mechanical equipment; plant tissue which has been stressed
by excesses of cold, heat or moisture; seeds should NOT be sampled as they
do not reflect nutritional status of the whole plant.

Crop Scouting is an essential part of Integrated Pest Management (IPM). Integrated Pest Management uses field-specific information and improved decision-making to protect crop yield and quality while minimizing the risks associated with pesticide use.
Through a regular and systematic field-sampling program, information gained by scouting fields is crucial for making decisions on in-season pest management treatments as well as making decisions about pest management in future years.
A well-designed scouting program includes three main activities:
1. Sampling to provide an accurate estimate of pest densities & crop health.
2. Identification of pests or diagnosis of the cause of crop injury based on
observable symptoms.
3. Comparison of observed pest pressure or crop injury to recommended
economic injury levels or thresholds.
