Soil Testing

Soil testing is an important management practice on all farms, whether growing vegetables for fresh market or pasture for livestock.  It’s nearly impossible to determine what a soil needs to be productive, without a soil analysis. There are many types of soil analyses available depending on what information you are seeking.  The most commonly requested analysis is for nutrient content, though you may wish to know what organisms are working in your soil, if there are pesticide residues or determine the particle size analysis.
