To get an accurate soil test, you need to carefully collect and prepare soil samples. This section describes how to collect a good sample. Get the Right Tool . A soil probe (Figure 2) or auger is ideal for taking soil samples.
Applying Lime to Raise Soil pH for Crop Production ...
catalog.extension.oregonstate.eduRaising soil pH with lime Soil acidification is reversed by adding a liming material. Liming materials are oxides, hydroxides, carbonates, and silicates of Ca and/or Mg. The anion in liming materials (chemically speaking, a “base”) reacts with soil acidity (H) to neutralize it (Figure 3). The most common liming material, “aglime,” sup-
Testing Your Soil Why and How to Take a Soil-Test Sample
www.nrcs.usda.govSoil tests indicate pH problems and allow recommen-dations for correcting them. • Available nutrient levels in the soil determine how good crop growth will be. Testing for phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) helps determine the need for soil amendments (phos-phate, and lime or dolomite) and the right fertilizer

This stratification has not adversely affected crop yield, but misleading soil test results may be obtained if samples are not taken to the proper depth. Shallow samples will Figure 8.1.

It is important that you know your individual state lime law when dealing with liming materials and amounts to be applied. An example of this is shown below: • One ton of lime is recommended from state soil testing laboratory (assuming 63% effective);

Soil tilth (how easily or difficult a field is tilled) is influenced by texture, soil moisture, aeration, and organic matter as well. Soil Textural Classes The combined portions of sand, silt, and clay in a soil determine its textural classification.
