10 Easy Soil Tests That Find Your Garden’s Problems

  1. Soil Structure and Tilth

When the soil is neither too wet nor too dry, dig a hole 6 to 10 inches deep. Separate an intact section about the dimensions of a soup can and break it apart together with your fingers. Determine whether the soil is cloddy, powdery, or granular. Ideally, your soil should be made from different sized crumbs which will hold their shape under slight pressure. Crumbs or aggregates, as soil scientists call them  that break apart only with difficulty mean your soil is just too hard.

Why it is vital

“Soil rich in organic matter tends to make relatively round aggregates, which results in porosity,” says Tom Thompson, Ph.D., a professor of soil science, also at the University of Arizona. Open, porous soils allow the free movement of water and oxygen, he explains, so plants can develop strong, healthy roots.

2. Compaction

Plunge a wire flag vertically into the soil at different locations. Mark the depth at which the wire bends. the earlier it bends, the more compacted the soil. A foot or more of easily penetrable soil is right .

Why it is vital

Compacted soil inhibits root growth and water availability, and keeps earthworms and other vital soil fauna from circulating freely.

3. Workability

You may have already learned about your soil’s workability the last time you bought the garden ready for planting. If tilling or digging the soil produces cloddy or plate-like clumps, the workability is low. Farmers measure workability by monitoring what proportion tractor fuel they use; you’ll simply judge the trouble necessary to organize beds for planting.

Why it is vital

Workable soil allows water to succeed in roots efficiently and it’s less susceptible to compaction. Fail this step, and your garden will likely show disappointing results for several of the opposite tests. “If the soil isn’t easily worked, other problems have already been happening for a short time ,” says Raymond Allmaras, a soil specialist with the USDA’s Agricultural Research Service in St. Paul, Minnesota.

4. Soil Organisms

Measure the animal life in your soil by digging down a minimum of 6 inches and peering intently into the opening for four minutes. check the amount and species of every organism observed, like centipedes, ground beetles, and spiders. Because most soil organisms spurn daylight, gently probe the soil to unearth the more shy residents. If you count but 10, your soil doesn’t have enough active players within the organic phenomenon .

Why it is vital

A thriving population of diverse fungi, bacteria, insects, and invertebrates is one among the foremost visible signs of soil quality. The more that creeps and crawls under your garden, the less opportunity there’s for unwelcome pests and disease. Each level of soil life does its part to interrupt down plant residue and make more nutrients available for growth.

5. Earthworms

When the soil isn’t too dry or wet, examine the soil surface for earthworm castings and burrows. Then dig out 6 inches of soil and count the amount of earthworms squirming on the shovel. Three worms are good; five are better. The absence of worms means the soil doesn’t have enough of the organic matter they prey on . An exception: If you reside within the Southwest, don’t waste some time looking albeit the soil displays other signs of excellent quality. “Earthworm activity is a smaller amount likely within the desert,” says Walworth. “Worms do not like hot soil.”

Why it is vital

Not only do earthworms aerate the soil, but their castings infuse the soil with enzymes, bacteria, organic matter, and plant nutrients. They also increase water infiltration and secrete compounds that bind soil particles together for better tilth.

6. Plant Residue

If you’ve grown a canopy crop, dig down 6 inches one month after turning it into the soil then search for plant matter. The range of organic material is vital to note here. The presence of recognizable plant parts also as plant fibers and darkly colored humus indicates a perfect rate of decomposition.

Why it is vital

“The single most vital component of healthy soil is organic matter,” Thompson says. But plants and other organic materials decompose only soil organisms are there to try to to the work. Any sign of this process may be a good sign, but the speed of decomposition is vital , too. Fast decomposition is another indicator of soil quality. In poorly aerated soil, plants break down slowly, a condition that provides off a faintly sour scent.

7. Plant Vigor

Start this test during the active season and appearance for healthy plant color and size that’s relatively uniform. Overall health and development must be judged against what’s considered normal for your region. One caveat: If you suffered a pest infestation or planted late or during a drought, results of this test could also be unreliable.

Why it is vital

Plant vigor indicates soil with good structure and tilth, a well-regulated water system , and a various population of organisms. it is the best sign of effective soil management you will have above ground.

8. Root Development

Use a shovel or hand trowel to dig gently around a specific plant, preferably a weed you will not miss. Once you’ve reached root depth, pull an annual plant up and check the extent of root development, checking out fine strands with a white healthy appearance. Brown, mushy roots indicate serious drainage problems — and a poor outlook for this year’s harvest. Stunted roots may additionally indicate disease or the presence of root-gnawing pests. “When you check out the roots, you’ll really see what is going on on,” Allmaras says.

Why it is vital

Roots have the foremost immediate reference to and reliance on soil quality. Without air, water, biological activity, and crumbly soil to grow in, roots can’t do their job.

9. Water Infiltration

Take an empty can with rock bottom removed and push it into the soil until just 3 inches remain above the surface. Fill the can with water, marking the water height and the way long it takes for the water to be absorbed into the soil. Repeat this several times until the speed of absorption slows and your times become consistent. Anything slower than 1/2 to 1 inch per hour is a sign of compacted soil.

Why it is vital

Good infiltration gets water to plants where they have it (at their roots), prevents runoff and erosion, and lets air move more efficiently into soil pores.

10. Water Availability

Wait for a soaking rain; then record how long until plants start to point out signs of thirst. Results will vary widely by region. the essential lesson is that if plants require more frequent watering than typical for your region, your soil is perhaps the culprit.

Why it is vital

Porous soil can better resist evaporation and adequately supply plants between waterings. “It could make all the difference within the world if water were to travel another inch deeper,” Allmaras says.
