Fertilizer Spill Cleanup

A fertilizer spill can harm people, water and soil, and the right response depends on the product and the size of the spill. This guide gives the general approach and points you to the agencies that set the rules.

What comes first when a spill happens?

People come first. Move children, animals and bystanders away, and keep anyone who is not trained out of the area. If anyone is hurt, feeling ill, or if the product is a gas or a large liquid release, call 911.

Do not rush to clean up. The product label and the safety data sheet tell you what the material is and what it can do, so find them before you start.

How do I know whether I can handle it myself?

Small, contained spills of some dry products may be manageable by trained workers using the right gear. Larger releases, anything near water, and anything involving a pressurized or reactive product belong with professionals.

When you are unsure, treat it as beyond your ability and call. Your fire department, your supplier and your state environmental or agriculture agency can all help you decide.

• Is anyone hurt or showing symptoms?
• Is the product a gas, or is it flowing toward a drain or water?
• Do I know exactly what the product is?
• Do I have the right protective gear and training?

What about keeping the spill from spreading?

Containment is about stopping movement. Preventing product from reaching drains, ditches, wells and surface water is the main goal, and it is often easier to do early than late.

Specific containment materials and methods depend on the product. Ask the supplier or the agency for guidance instead of mixing products or adding water on your own, which can make some spills worse.

Do I have to report a spill?

Some spills must be reported to state or federal agencies, and the thresholds and deadlines depend on the product and the place. This site does not state those numbers.

Call your state department of agriculture or environmental agency and ask what applies. Keep notes on when the spill happened, what product it was, how much, and what you did.

How should cleanup material be handled?

Collected product and contaminated soil or absorbent may need special disposal, and in some cases may be usable again. Do not dump it in a field, a ditch or a household trash bin without checking.

Ask the supplier and the state agency about the right path. Label containers clearly and store them where children and animals cannot reach them.

How can I prevent the next spill?

After any spill, look for the cause. A worn hose, a loose fitting, an overfilled tank or a rushed transfer is often the story.

Fix the cause, update your routine and talk it over with everyone who helps. Keep spill supplies in a known spot, and make sure the people who work there know what is in the kit and how to get help.

Spills are stressful, and stress leads to shortcuts. Decide now, on a calm day, who makes the calls, who keeps people back and who gathers the safety data sheet. Practicing the plan once a year, even as a short conversation around the shop, makes the real thing go better. Afterward, take a few minutes to talk through what worked and what did not, and write down one change to make before next season.

What should a spill kit and plan include?

A spill plan is a short written page: who to call, where the supplies are, what the products are and where the safety data sheets live. Keep it with the supplies and review it each year.

The kit contents depend on the products you handle. Ask your supplier and your extension office what makes sense for your operation, instead of assembling a kit from an online list. Spills in transit or on land you do not own raise extra questions about reporting and liability. Call 911 if the road is blocked or anyone is at risk, and then call your supplier and the proper state agency.

Take photos, write down what you remember and avoid guessing about the cause when speaking to others. Honest, simple facts are the most useful.

• Phone numbers for 911, your supplier and your state agency.
• Location of safety data sheets.
• Labeled containers for collected material.
• Protective gear that fits the people who will use it.
