What's the difference between healthy and unhealthy soil?
Healthy soil is teeming with life and nutrients, while unhealthy soil is challenged by erosion, invasive species, and more.
- 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.
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.
Insufficient or excessive supply of nutrients. Inadequate soil depth. Insufficient population of positive microorganisms and helpful creatures, such as certain bacteria, earthworms and bees.
- Good soil tilth.
- Sufficient depth.
- Sufficient, but not excessive, nutrient supply.
- Small population of plant pathogens and insect pests.
- Good soil drainage.
- Large population of beneficial organisms.
- Low weed pressure.
- No chemicals or toxins that may harm the crop.
Soil in a healthy garden should be a nice, dark, black color. Soil with little to no life in it looks more like dirt: brown and dry. This poor soil will turn to brown mud when it gets wet. Healthy soil absorbs moisture beautifully and should not have a muddy feel.
Some characteristics of healthy soils include good soil tilth, good soil drainage, large population of microorganisms, sufficient (but not excessive) levels of essential nutrients, and low weed pressure.
No matter how bad your soil is to start with, adding organic matter can make any soil better. The good news is that either condition can be improved to make your soil more hospitable to the plants you want to grow there.
Unhealthy soil does not have the nutrients to support as many plants as healthy soil. Fewer plants in the ground means that less photosynthesis occurs, which in turn means that less carbon is being pulled out of the air and stored in plant roots as carbon-based sugars.
Healthy soil contains aggregates that help it bind together, preventing erosion and run-off. It can hold more water, so plants fare better in drought. It contains more bacteria and fungi that help plants fight diseases and pests. And healthy soil also contains more minerals and nutrients that feed plants.
What's an example of bad soil?
Cracked Or Dry Soil
For example, soil erosion from wind or excess rainfall can cause a property to become dry and dusty, making it hard for plants, trees, or grass to survive. In addition, soil can become cracked or dry due to low rainfall or little to no regular irrigation.
Diverse crop rotations can reduce pests and diseases that are specific to certain plant species, build the health of soil microbes that provide nutrients to your plants and ultimately lead to improved yields.
Good soil structure is soft and crumbly, with granular aggregates that hold together even in water. Soil structure can also be blocky, platy, columnar or structureless, such as a single-grain sand or a massive clay soil.
In the last few decades, soil degradation has been sped up by intensive farming practices like deforestation, overgrazing, intensive cultivation, forest fires and construction work. These actions disturb soil and leave it vulnerable to wind and water erosion, which damages the complex systems underneath.

Poorly drained soils are often dominated by blue-grey colours often with yellow mottling. Well drained soils will usually have bright and uniform colours.
Soil color is also important to pay attention to. Generally speaking, colors that indicate good soil are dark brown, red and tan. Dark brown suggests that the soil has a good percentage of organic matter. Red reflects the oxidized iron content of the soil, while tan indicates a combination of organic matter and iron.
Examine the crop regularly, at least weekly, for symptoms of disease or signs of pathogens. Select a few plants from different locations, remove plants from their containers, and gently scrape or wash away soil. Examine roots and crowns for discoloration, softness, shriveling, or other early indications of disease.
Soil colour
Black/dark brown soil usually indicates the presence of decaying organic matter so is generally fertile. Pale brown/yellow soil often indicates that organic matter and nutrients are low and this generally means poor fertility and structure. Pale soil needs plenty of organic matter and mulching.
What are the 3 main nutrients for soil health?
Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K).
The correct balance is where the soil pH is between 5.5 and 7.5, so every effort should be taken to check soil pH levels regularly. Early identification of soil pH problems is important as it can be both costly and difficult to correct long-term nutrient deficiencies.
Opened bags of new potting soil can retain quality for around 6 to 12 months. For unopened and unused potting soil, you can store it for about a year or two before it goes bad.
While it may seem like poor soil health is a death sentence for your garden, there are many plants that have adapted to poor soil, and grow quite well in these conditions. Plants are tenacious, and many have adapted to rocky, soggy, overly dry, or clay soil. Before you plant, check your hardiness zone.
If your soil is doing this, chances are your plants might not get enough water or nutrients either. Many nutrients are carried to plants in water, and plants showing deficiency for these nutrients – such as potassium – can actually have enough nutrient in the soil if only there was enough water to carry it to them.
Too wet - wet season, wet soil or overwatering. Remedy: Check the soil around new plants for standing water or waterlogged conditions. Reduce watering where necessary (remember plants in the ground do not need to be watered as frequently as those in containers). Choose plants suited to wet soil conditions.
Since the roots of plants get the oxygen they need from the air in those spaces, the roots can literally drown in a soil that stays waterlogged over an extended period. In turn, a sick root system leads to a sick plant. Plants in such situations often lose vigor, look wilted, turn yellow, are stunted and often die.
Soils such as sand and clay are not suitable for growing crops. Sandy soil loses water at a high rate leading to a low level of water retention that is unsuitable for plant growth.
Soil compaction (dense soil that drains water very slowly), topsoil removal, and erosion are three key soil problems. Evaluating your soil and making necessary adjustments and improvements prior to planting will save you time and money and result in a healthier landscape.
Sliding is the most common cause of soil failure. Sliding and other modes of failure can occur in soils that are not densely compacted.
What is the best soil quality?
Loam soil is often thought of as the ideal soil type for plants because it's a combination of all the above-mentioned soils. It also has enough nutrients to sustain plants and crops. It's easy to plant with and drains well. Numerous plants and crops plant well in loam soil.
The most fertile soils on Earth are the so-called black soils or chernozems. These are found in some areas in North America, Central Europe, Eastern Europe and Russia. It took several millennia and a specific climate and steppe vegetation for them to form.
The ideal soil texture is a mix of sand, silt, and clay particles, known as a loam. However, in most cases, the particles will not be balanced, and the soil will need to be altered by adding organic amendments. To evaluate soil texture, use a simple jar test to determine the percentages of sand, silt, and clay.
- a plant looks dried out and pops right out of the pot when you try to remove it.
- you water the plant and the water runs through to the pot's dish, which mean there's no more organic materials left to retain moisture.
- the plants aren't growing well and start to look slightly yellowish.
- Mix one-half cup vinegar with a scoop of soil. If it fizzes or bubbles, your soil is alkaline.
- Mix one-half cup water with a scoop of soil, then add baking soda. If it fizzes or bubbles, your soil is acidic.
- If neither reaction occurs, your soil is balanced, or neutral.
pH: pH is an important indicator of soil health because if there is inadequate soil pH, crop growth can be impacted and key nutrients may become less available.
As potting soils decompose, bad things happen to your plants: The potting soil compresses. It looks like the dirt is settling because there seems to be less of it, but the peat moss is breaking down. As it does, the peat and soil particles pack around the plant's roots and slowly starve them of oxygen.
Legionella longbeachae, a bacteria commonly found in potting mix, can cause Legionnaires' disease, a form of pneumonia. This disease is often caused by inhaling or by spreading the bacteria from hand to mouth after handling potting mix, soil or compost.
Typically, changing the soil in your potted plants should happen every 12 to 18 months. There are some exceptions that may change this timing. These include if you're moving a plant into a bigger pot because it's outgrown its current pot or if the soil has become very hard.
Besides indicating nutrient deficiencies, a soil test can also provide information on soil acidity, the percentage of organic matter in your soil, and your soil's texture.
Can I test my soil myself?
You can test your own soil using a basic soil test kit from The Home Depot. Inexpensive, easy and accurate, soil tests provide a wealth of knowledge about what's going on under your feet, including the levels of pH, calcium, lime, gypsum and potassium.
Scoop some soil into a container. Then, add 1/2 cup of vinegar. If the soil bubbles or fizzes, it's alkaline. The chemical reaction that you're seeing occurs when an acid (vinegar) comes into contact with something alkaline (soil).
The chemical indicators that can be directly measured in the field are soil pH, EC, nitrate-nitrogen, and phosphorus-phosphates (measured by P test strip particularly in the Midwest).
Soil color is also important to pay attention to. Generally speaking, colors that indicate good soil are dark brown, red and tan. Dark brown suggests that the soil has a good percentage of organic matter. Red reflects the oxidized iron content of the soil, while tan indicates a combination of organic matter and iron.
