Soil Testing

Lawns and Gardens

Picture
For proper management, a soil test for available nutrients should be made every 3-5 years.  This will help prevent over application of nutrients from fertilizers and other sources.
Proper collection of a soil sample is important.  Test results will be no better than the sample collected.  Accuracy of analysis depends on the collection of a representative soil sample.
Try to take samples when the soil is not wet.  If your samples are wet, spread the soil out to AIR DRY, do not use heat, before sending them in.  Sampling probes and bags may usually be obtained at your local Extension office.
​ Follow these steps to obtain a good soil sample:

1.  Lawn soils should be tested before planting, if possible.  From each lawn or garden area, take at least 10 cores or slice samples to properly represent the area.
  • ​Collect soil 6-8 inches deep for the standard test (nitrogen, phosphorus, potassium and soil pH (Lime requirements).
  • Avoid sampling in old fence rows, along limestone rock roads, low spots and other areas that might give misleading results.  If information is desired on these unusual areas, obtain a sample from them.
2.  For each desired area, collect samples into a clean PLASTIC container and mix thoroughly.  Remove any stones, grass, roots or "thatch".
3.  Put one cup of the soil mixture into a paper bag.
​4.  Clearly label your bag:  Garden, Backyard, etc. so you know where it represents.
​5.  Take representative samples to your local Extension office.
  • Note: The Shawnee County Conservation District Non-Point Source Pollution Program promotes soil testing by paying a portion of the fees for analysis.  For payment, areas being tested must be within the boundaries of Shawnee County, Kansas.  Samples must be taken to:  Shawnee County K-State Research & Extension Office, 1740 SW Western Avenue, Topeka, Kansas 66604-3095, phone: 785-232-0062.

Agriculture Fields (Cropland & Pastures)

Picture
For proper management, a soil test for available nutrients should be made every 3-5 years. This will help prevent over application of nutrients from fertilizers, manures and other sources.  Preventing agricultural pollution.
Proper collection of a soil sample is important. Test results will be no better than the sample collected. Accuracy of analysis depends on the collection of a representative soil sample.
Try to take samples when the soil is not wet. If your samples are wet, spread the soil out to AIR DRY, do not use heat, before sending in. Sampling probes and bags may usually be obtained at your local Extension office.
Follow these steps to obtain a good soil sample:

1.  From each field or area of a field, take enough samples to properly represent the plot, 20-30 cores or slices per field would be typical. If it is one large field you should keep separate samples from the bottom land and upland portions.
  • Collect soil 6-8 inches deep for the standard test (nitrogen, phosphorus, potassium and soil pH (Lime requirements). A second sample down to the 24 inch level is needed for a nitrogen profile test. These samples MUST be kept separate from the upper layer.
  • Avoid sampling in old fence rows, along limestone rock roads, low spots and other areas that might give misleading results. If information is desired on these unusual areas, obtain a sample from them.
2.  For each desired area, collect samples into a clean PLASTIC container and mix thoroughly.
3.  Put one cup of the soil mixture into a paper bag.
4.  Clearly label your bag so you know what field it represents.
5.  Take 
representative samples to your local Extension office or farm dealer.
