Do you have Acid in your Soil?

What type of soil do you have?

Soil chemistry is very complex topic. There are laboratories and advanced

college courses dedicated entirely soil science. Knowing the measurements of

a few soil components can greatly increase the health of landscape plants and

the lawn. When things go seriously wrong with the soil, plants will start to

display some symptoms of nutrient deficiency. Potted plants, growing in a

limited amount of soil, tend to show deficiencies much more. When grown in

the ground, plants also symptoms indicating the soil needs some adjustment.

When there is a problem with the soil chemistry, plants show stunted or

abnormal growth. The pH and other factors affect the availability of

nutrients. In some cases, elements and micronutrients, including metals, are

unavailable to the plants. These type of deficiencies affect the production

of chlorophyll. The yellowing of the leaves if typically related to a

deficiency.

Knowing the pH and amount of nutrients and metals is valuable in new and

established landscapes. In some cases, when moving into an older home it

might be beneficial to test for contaminants like arsenic or lead. A basic

soil test includes the pH, and possibly the phosphorus and potassium content,

which are important nutrients from strong roots and beautiful flowers.

Ideally, a full soil test would also include the micronutrients iron,

manganese, and zinc.

For most of us, we don't really know what was on the property before we

arrived. To make sure the test is an accurate representation of the soil

on-site, collect samples from two to three points around the yard. Take two

samples if there's an indication that topsoil was brought in or there are

two areas with different characteristics. To get a good indication of the

soil the plants will be growing in, dig a hole about six inches deep that is

the levels where the majority of the roots will be growing. Collect soil

samples using a clean garden tool. Dig into the side of the hole to collect

clean soil for the most accurate analysis. For most yards with native soil,

combining the samples from two or three places in the yard will give a good

analysis of the general state of the soil. Allow the soil to dry overnight.

The next day package a heaping one cup of soil in a zip lock bag for soil

testing.

Cooperative extensions all over the country offer soil tests through the mail

as do independent laboratories. For preventative care, most common nutrient

deficiencies can be prevented with a regular side dressing of humus or

compost.
