Quick Answer: What Does A Soil Test Tell You

The soil test will tell you the percentage of organic matter you have in your soil and will “credit” you a certain amount of nitrogen for it. This will minimize the risk of applying excess nitrogen which might then wash out of your soil and into surrounding waterways.

What does a soil sample tell you?

A soil test can determine the current fertility and health of your soil. By measuring both the pH level and pinpointing nutrient deficiencies, a soil test can provide the information necessary for maintaining the most optimal fertility each year.

What do soil test results look for?

Keep in mind that a soil test is a chemical way of estimating the nutrients available to the plant. The pH is a measure of soil acidity. Generally 6.6 or lower indicates acidic soil, 6.7 to 7.3 means neutral soil, and a reading higher than 7.3 means the soil is basic.Tags: Soil Test. Phosphorus. Potassium. Fertilizer.

Why should a homeowner perform soil testing?

Soil testing for new homes is needed in order to determine the composition of the soil and if it can properly support a foundation. If extra foundation supports are not used, the expansion and contraction of the soil due to moisture content can result in cracked and crumbling foundations.

What do you check in a soil test?

Available nutrient levels in the soil determine how good crop growth will be. Testing for phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) helps determine the need for soil amendments (phos- phate, and lime or dolomite) and the right fertilizer formulations for the crop to be grown.

How deep should soil samples be taken?

The recommended sampling depth for gardens is 6 inches. This is the normal spading depth of most garden soils. Take soil samples to a depth of 4 inches. This is the actual soil depth and should not include roots or other accumulated organic material on the surface.

How much does soil testing cost?

Soil testing costs $1,360 on average with most spending between $811 and $2,052. Garden soil testing costs $10 to $200 per test. Contamination testing, for things like lead, cost anywhere from $15 to $400 each.

How do you read soil results?

A reading of 7 is neutral; crops typically grow best when pH is between 6 (slightly acidic) and 7.5 (slightly alkaline). Results of soil pH are reported on a logarithmic scale; a soil with a pH of 6 is 10 times more acidic than a soil with a pH of 7, and a pH of 5 is 100 times more acidic than a pH of 7.

How do you read a lawn soil test?

The soil pH scale is measured from 0 to 14. A reading of 7.0 is the middle of the scale and is considered to be neutral. Anything below 7.0 is acidic and anything above 7.0 is basic or alkaline. Each movement of one whole number on the pH scale represents a change by a factor of 10.

How accurate are home soil test kits?

La Motte Soil Test Kit had the largest range of pH measures, whereas Rapitest was relatively easy to use and interpret and is a practical choice for home gardeners or landscapers; both were more than 90% accurate for this soil type.

How long does a soil test last?

How long will my soil testing take? Usually, soil testing results are delivered in 10 days, plus an allowance (of around 8 days) for travel time if it’s a regional area. We always try to visit a site within 3 days (but this could take more time, depending on the location), then spend 2 days in the lab.

How do I know if my garden soil is safe?

Signs of healthy soil include plenty of underground animal and plant activity, such as earthworms and fungi. Soil that is rich in organic matter tends to be darker and crumbles off of the roots of plants you pull up. A healthy, spread-out root system is also a sign of good soil.

Should you test your soil?

Test your soil at least once every three years. Keep the test results handy so that you can monitor any changes in soil fertility. You may want to test more often if you have a problem area or if you’ve applied lots of nutrients.

What are signs of unhealthy soil?

3 Signs Your Soil Mix Is Unhealthy Lack of Moisture. Unhealthy soil doesn’t have the moisture and nutrients needed to thrive, which makes it dry, crumbling, and cracked. Poor Growth The successful growth of grass, plants, and flowers starts with the soil mix. Compacted Soil.

What are the 13 types of soil?

Soil Types Sandy soil. Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients. Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients. Silt Soil. Silt Soil is a light and moisture retentive soil type with a high fertility rating. Peat Soil. Chalk Soil. Loam Soil.

How do I know if my soil is healthy?

Soil health cannot be determined by measuring only crop yield, water quality, or any other single outcome. Soil health cannot be measured directly, so we evaluate indicators. Indicators are measurable properties of soil or plants that provide clues about how well the soil can function.

How many soil samples should I take?

Ideally, large uniform fields should have 1 composite sample collected per 20 acres or less. Smaller fields, including contour strips, should have 1 composite sample collected per 5 acres, especially on hilly or rolling ground.

What are the tools needed in soil sampling?

Push probes, hammer probes, and bucket augers (Figure 1) are commonly used because they are capable of taking uniform samples with depth. Figure 1. Examples of soil sampling equipment: a soil push probe, hammer probe, and bucket auger. Along with a probe, a clean plastic bucket should be used.
