Importance of Good Soil
Good soil is ninety percent of the secret to a successful garden. Without it,
you will be fighting a losing battle no matter how diligent you are with
watering, weed control, ensuring proper sunlight, and pest control.
The quality of a soil is usually determined by examining its fertility and
texture. A soil’s fertility is determined by a combination of essential
nutrients and a pH that makes these nutrients available to the plants. The
basic nutrients required by plants are nitrogen, phosphorous, and potassium.
Nitrogen is responsible for the healthy growth of the plant’s leaf and stem,
phosphorous is important for the root growth of the plant, and potassium is
required for the overall health of the plant, keeping the plant growing and
boosting its immune system. In addition to these three nutrients, plants also
require trace elements such as calcium, magnesium, molybdenum, and zinc in
order to be healthy. The pH of a soil tells us its acidity or alkalinity level
and is measured on a scale between 1.0 and 14.0. A pH level of 7.0 is
considered neutral. Soil with a pH higher than 7.0 is considered acidic and
soil with a pH higher than 7.0 is considered to be alkaline.
A soil’s texture, on the other hand, refers to its particle content, the size
of particles, and how cohesive they are. Sandy soils have very large
particles, for example, whereas soils with a lot of clay have very small
particles. Both soil with a lot of sand and soil with a lot of clay can be
problematic. Sandy soil permits air, roots, and water to move too freely while
soil with a lot of clay does not offer enough room for air, roots, or water.
There are a number of steps you can take to bring your soil into the best
shape possible for a garden and there are definitely things you should avoid
doing so as not to harm the quality of your gardening soil. Enriching your
soil with fertilizer and organic material is one of the best ways to make sure
your garden will be healthy. Soil enriched with fertilizer and organic
materials stimulates plant root systems to go down deep and to spread out, and
the resulting plants are stronger, sturdier, and better able to withstand
disease, heat and drought. Manure is a great fertilizer as long as it is aged
enough and doesn’t contain too much salt or weeds. Organic material can
consist of anything from kitchen scraps such as eggshells, potato peels, and
coffee grinds, to plant residues such as grass cuttings, pine needles and
leaves to even earthworms!
When you are improving and enriching your soil, be sure not to mix a different
type of soil with your existing soil. For example, you wouldn’t want to mix a
sandy soil with a clay soil – this would produce disastrous results. Also,
when adding organic material, make sure you don’t use plant residue that
consists of diseased plants or organic material that has meat scraps. Finally,
sewage sludge can be used but it may contain high levels of lead and cadmium
so it is best to use this material only on plants that you are not intending
to ingest.
