It is always a good idea to know the analysis of the fertilizer you are purchasing or manufacturing. Regulatory specifications require manufacturers to be able to verify their claimed contents. The failure to meet specifications can result in a fine for the manufacturer. Be sure to protect yourself and your investment by having your fertilizer products analyzed.

Agricultural Lime is one of the least expensive, but most valuable inputs a producer can utilize in their soil fertility program. Proper soil pH is the basic building block of any soil fertility program and a major factor in nutrient availability. There are numerous sources of agricultural lime located in all regions of the United States. However, each source can vary in physical and chemical quality. Lime testing allows distributors and producers the knowledge to make proper lime applications.
