Soil Analysis

Soil Technologies begins by discovering what is missing in the soil. A few of the factors that have most likely affected your soil over the years are moisture, temperature, light tillage, heavy plowing, organic matter decomposition, nitrogen levels, cropping and fertilization

Step One: Boundary Mapping

Using a GPS system, we start by mapping the perimeter of a field.

Step Two: Electrical Conductivity Testing

Soil Technologies uses an electrical conductivity (EC) tester to measure soil variability or ranges within farm fields. For example, smaller soil particles such as clay conduct more current than larger silt or sand particles. This makes the zones easy to identify, which is important for you to know since clays contain higher amounts of plant nutrients than silt or sand.

Since this is a one-time analysis, EC testing is a low cost effective way to chart or map different zones for soil testing, spreading fertilizer and plant tissue testing. Additionally, the EC zones can be given to your fertilizer company to variable rate spread according to your soil test results, your zones and your budget.

Step Three: Soil Sampling

Soil testing will help you ensure that your farm is sustainable. Because this is also important to us, Soil Technologies wants to help you reduce your costs in testing. We do this by taking samples of your soil at various locations within each EC zone. Your soil samples are then sent to a highly reputable lab for a detailed soil analysis system for fertility management, using the principals developed by Dr. William Albrecht (1888 to 1974), agronomist at the University of Missouri. His teaching and research showed us that “when optimum ratios of bases exist, the soil is believed to support high biological activity, become resistant to leaching, and have optimal physical properties (water intake and aggregation). The plants growing on such soil are also balanced in mineral levels and are nutritious to humans and animals alike.” (Preston Sullivan, ATTRA Technical Specialist, Fayetteville, AR)

Soil sampling by Soil Technologies can take place at any time after an EC test is complete.

Step Four: Prescription Mapping

Once you receive your soil mapping data, Soil Technologies can give you a prescription for each zone. Having this data will save you time, and ultimately cost, since not all zones require the same level and/or type of nutrients.
