Fertilizer Analysis

Why Test? | Available Tests | Sampling Guide | Submittal Forms | Example Reports

The analysis of both custom blended and manufactured dry and liquid fertilizers must meet certain specifications on the plant food contained in the fertilizer. Failure to meet these specifications can result in substantial fines. Each State performs regular, random fertilizer analysis for regulatory purposes. However, it is in the fertilizer dealer's best interest to have the state inspector pull two samples when they inspect the product. The dealer can then retain one sample to be able to check the State's results, and possibly avoid an improper fine.

Sampling Guide

For Dry Samples - Obtain a dry material kit, which contains plastic "Zip-Loc" bags. Fill a bag with sample no less than one-half full. Squeeze excess air from the bag and seal it. Complete the fertilizer information form and write your sample number on the bag in permanent ink on the white panel of the sample bag.

For Wet Samples - Obtain a wet material kit, which contains plastic collapsible containers. Fill the container exactly one-half full of sample. Squeeze excess air from the bag and tighten the cap securely. Tape the lid to help is stay secure in transit. Complete the fertilizer information form and write your sample number on the container in permanent ink.

Shipping - Pack the samples securely in a shipping box, in a way that will minimize shifting and the possibility of rupturing the container. We recommend UPS, Fed Ex or USPS Priority Mail for fastest service.
