How do I take a soil sample?
In general, soils that differ in appearance, crop growth or past treatment should be sampled separately, provided the area is of such size and nature that it can be fertilized separately. For each sample, collect soil from 10 or more places in each sampling area in a zigzag fashion so as to make a representative sample. Mix thoroughly before filling a sampling carton or container to be mailed to the Lab. One soil sample should represent 10 acres or less. Avoid sampling directly in the fertilized band. Proper sampling depth depends on the kind of crop you plan to grow. We recommend that for pasture, turf, established orchards and minimum tillage, you take top 2-3 inches of soil and for cultivated crops, you collect upper 5-6 inches of soil.
