Home Soil Test

Why get your home soil tested?

Helps you grow healthier, more productive soils

Routine soil testing identifies what nutrients are needed or not needed in the soil. Soil pH, salinity levels, and soil texture are also analyzed. If plant nutrients are found to be deficient, the soil test will indicate amounts needed for optimum growth.

Responsibly protects the environment

Soil testing also reveals what nutrients are present in excess amounts that should NOT be added. Applying nutrients needlessly results in soil chemical imbalance and plant problems. Excessively applied nutrients contaminate water, adversely affecting public health and the environment.

Saves you money

You make better decisions and save money when you do not apply nutrients that are not needed. Wisely, you only apply what the soil needs.


Pick a Test and Complete a Form

Routine Test

Basic measurements for the vast majority of home gardening needs

Provides Phosphorus (P205) and Potassium (K2O) fertilizer recommendations

Provides soil salinity and pH levels useful in choosing appropriate plants for these important conditions in arid/semi-arid Western US environments

Provides a soil texture classification used to determine water holding capacity and irrigation regiment

Micro Plus Test

Starts out with all the features of the Routine Test

Includes key micronutrient levels that are often deficient in arid/semi-arid Western US soil conditions (Iron, Zinc, Copper and Manganese)

Provides recommendations for deficient nutrients tailored to the plants the client indicates are to be grown (please provide this information on the submission form)

Choose this test if micronutrient deficiency symptoms are seen or suspected the previous season. Micronutrient fertilizer applications are most effective in the early spring--much less effective mid-season.
