Soil Organisms Healthy soil is full of animal life. Dig a hole at least 6 inches deep. Watch the interior of the hole for 4 minutes. Look for earthworm casts or burrows on the surface of damp soil. Dig up a chunk of soil 6 inches deep. Count the worms you find in the chunk.
Five is the magic number, but three is still good. Dig a 6 — inch deep hole in damp soil. Remove a soup can-sized section intact. Break it apart Healthy soil consists of different sized aggregates or chunks that retain their shape when slight pressure is applied. If the aggregates are difficult to break apart, you have a hard soil problem.
Kellogg Garden Organics. All Natural Garden Soil. Learn More. Product Locator by Locally. Workability If your soil is hard to work or till and you get clods as a result, your soil has low workability. Compaction This is compressed, hard soil. Stick a wire into the soil. Mark the depth when the wire bends.
Water Infiltration Water infiltration is the process by which water reaches plant roots. Remove the bottom of a coffee can. Push it into the soil, leaving 3 inches above ground. If good soil could be achieved merely by buying a bag of fertilizer from the garden center, most Americans would be boasting perfect soil. While fertility is obviously an aspect of good garden soil, there is so much more involved.
Good soil has:. The next thing to consider is the structure of the soil. There are three main types of soil:. There are several things you can do to improve your soil. Luckily, they are actually all fairly easy to do. Test your soil: The first thing to do is learn all you can about your soil. You may want to try a couple of DIY soil tests to learn more about the level of life in your soil and what its texture is like.
Getting a soil test from your county's cooperative extension would be a great idea; this will alert you to any deficiencies or pH problems. Add organic matter: Adding organic matter is hands-down, without a doubt, the number one way to improve your soil. Whether your soil is clayey, sandy, low in nutrients, compacted, has poor drainage So what should you be adding to your soil?
Compost is a must--it will improve your soil immediately and introduce microorganisms that will continue improving your soil by further breaking down organic matter. Most plants grow in a pH of 6. While adding lime may raise pH or sulfur may lower it, these changes may be negligible at worst or temporary at best. Lime or sulfur may be applied to the topsoil layer but will do nothing to change subsurface pH.
In addition, clay soils have a high resistance to changes in pH high buffering capacity so more amendment may be needed than is practical. It is more advisable to choose plants adapted to a particular soil pH —a local horticulturalist can be very helpful. Soil nutrients important to plants include the macronutrients: nitrogen, phosphorus and potassium, as well as the secondary and micronutrients: sulfur, calcium, magnesium, iron, manganese, boron, copper, zinc and molybdemum.
A soil lab analysis helps us understand more about the site soil including nutrient levels and pH. Bear in mind that nitrogen, one of the most important elements for plant health, is extremely mobile and a soil test will only give you a snapshot of the nitrogen levels present on the day of sampling. A competent horticulturalist can also get an idea of possible nutrient deficiencies or sufficiencies by observing the health of existing plants on the site.
Not to a nitrogen-fixing plant that can compensate by converting atmospheric nitrogen into a form that can be taken up by the roots. For a soil nutrient analysis, samples are typically collected using an auger or core sampler in the top 6 to 8 inches of the soil, where most roots grow.
For a more or less homogenous site, collect more than one sample — a minimum of 10 samples per square feet and mix together to get a blended sample for testing. A larger site may need to be subdivided into smaller areas different depending on the characteristics or uses of each area. While collecting samples for lab analysis, a portion can also be field-tested for texture. To determine soil structure, collect samples from a larger hole or pit.
For a soil profile assessment, collect samples with an auger in the top 3 to 6 feet, to get an idea of the properties of each soil layer, including color, texture, moisture level and amount of living roots found. In a soil profile analysis, the samples are laid out next to each other, not mixed, with careful notes taken about the properties of each sample at each depth.
