Water and Soil Testing for Oregon and Southern Washington

Why do I need to perform soil and water testing?

Ensuring the wellbeing of your soil and water requires routine pH testing. Most plants will grow most effectively when their soil has a pH of approximately 6.5 to 7.0. But why is the pH of your soil and water so important? If your soil becomes too acidic or basic, plants may not be able to retrieve necessary minerals from the soil. The best way to ensure the health of your plants is through proper soil and water testing.

Over time, carbon dioxide in the atmosphere mixes with rain to produce carbonic acid. This acid has the ability to dissolve lime which is necessary for plants to keep the pH of their soil balanced. Routine testing will also let you know about any mineral deficiencies in your soil.

When is the best time of the year to perform testing?

In the Northwest, winter is an ideal time to perform soil and water testing. Broadcasting lime on the surface will allow the rain to dissolve it and move it down into the root zone. There are two common sources of agricultural lime. Dolomite lime contains approx. 51% calcium carbonate and 40% magnesium carbonate. Powered limestone contains approx. 65-80% calcium carbonate and 3-15% magnesium carbonate.

Soil sampling is one of the simplest land management tools available to today’s grower. The science behind soil analysis establishes a baseline inventory of soil composition. Using the information that soil sampling provides to manipulate soil composition is what fertility is all about.
