The Neighborly Soil Test allows you to submit 3 soil samples for the basic analysis and get a discount of 30% off the Basic Test Kit price. The basic analysis measures soil pH, percent organic matter, phosphorus, potassium, magnesium and calcium - primary nutrients for plant nutrition. We recommend this test when you have a large landscapes or multiple planting areas (lawn, flower gardens, vegetable, shrub borders, trees etc.) Separate recommendations are given for each sample. This creates a historical record of the soil conditions to refer back to when retesting. Also, this test comes in handy when diagnosing problems allowing you to compare planting areas of healthy and unproductive growth.
