Soil Testing
When done accurately, soil testing gives
the most accurate assessment of the nutrient environment
for your plants. Also, with proper research and interpretation,
a soil engineer can give the best estimate of fertilizer
needs and advise on preventive solutions for problems that
may arise from expansive or unsuitable soil, saving the
homeowner much time and money.
A soil engineer's main job is to inspect
anticipated construction sites to work out soil and foundation
conditions by conducting drilling and sampling programs.
They are responsible for managing and designing irrigation,
foundations, flood and erosion control systems, dams, earth-retaining
structures and water conservation projects. A soil engineer
can be contracted directly or through the architect. Soil
engineers should always be registered and professionally
licensed through the state.
Expansive soils are one of the most crucial
hazards, in addition to earthquakes and land slips. Expansive
soils are naturally occurring materials found in low lying
regions and flood plains. They are subject to swelling and
shrinkage of the soil, varying in part to the amount of
moisture present in the soil. The effects of expansive soil
include patios, driveways and walkways cracking and heaving
as the underlying expansive soils become wet and swell.
Millions of dollars are lost each year due to damage caused
by them.
Not only can a soil test protect against
any environmental hazards resulting from excessive fertilizer
applications, but it is also be used to determine the nutrients
in soil that are essential for plant growth. Nutrients for
healthy plant growth are divided into three categories:
primary, secondary and micronutrients.
In addition, a soil report will tell you
the pH value (how acidic or basic) of your soil, and it
will make a recommendation for the amount and type of fertilizer
and/or lime you need to add to the soil for optimal plant
growth. This allows you to tailor your soil fertilizer and
lime applications to your plants' needs.
Keep in mind, soil testing is usually required
by building permits as well. This is because soil testing
also looks at the soils ability to support a structure and
the absorption and drainage rate of the soil or how well
it will accommodate septic and water. A soil test can be
ordered through a real estate agent or home buyer.
