Services | Fertilizer & Lime Analysis

Is your fertilizer perfectly formulated to produce thriving, healthy crops?

Send us a sample – we’ll analyze your fertilizer and see what’s inside.

Want to make sure that your fertilizer is getting the job done?

Variables such as age and storage conditions can degrade fertilizer components, making it difficult to know if what’s on the label is actually making it to your plants. Accurate, reliable testing can help you make informed decisions.

Fertilizer testing can reduce waste and save you money.

Every dollar counts when it comes to crop inputs! Using the wrong formula or applying the wrong amount of fertilizer is going to cost you. Ward Laboratories will test your fertilizer and give you a detailed report of the results, eliminating risk and guesswork.

Here are two of the tests our growers and producers rely on:
