When you’re growing plants, it’s important to consider how microbes impact soil and plant health. While these small organisms are often invisible to the naked eye, they have visible impacts on plant growth and vigor.<\/p>\n\n\n\n\n\n

Certain types of bacteria and fungi play a big role in soil\/media health. Therefore, they largely impact plant health in ways such as increasing nutrient uptake, improving tolerance to drought, and protecting against disease.<\/p>\n\n\n\n

In fact, organic production is impossible without microbes. While conventional production can rely on chemicals for nutrition and pests control, organic production cannot. <\/p>\n\n\n\n

Plants in organic systems rely on microbes to convert organic nutrients into available forms. Also, plants rely on these beneficial organisms to boost their immune responses and overall plant health.<\/p>\n\n\n\n

If you’re looking for a way to increase the beneficial bacteria and fungi in your soil, you can innoculate your growing media. Products such as Amplify provide your media with a broad spectrum of beneficial microorganisms<\/a>.<\/p>\n\n\n

<\/p>\n\n\n

What does Microbe Mean?<\/h2>\n\n\n

<\/p>\n\n\n

People often use the word microbe instead of saying microorganism. As you might guess, both words refer to small organisms<\/a>. These organisms include bacteria, fungi, algae, and protozoa. It’s important to note that they do NOT include viruses.<\/p>\n\n\n

<\/p>\n\n\n

Don’t forget that microbes are not inert chemicals, and they are not nutrients. Rather, they’re alive! Therefore, they can multiply and quickly take over an area.<\/p>\n\n\n

<\/p>\n\n\n

Microorganisms in Soil: Why do They Matter?<\/h3>\n\n\n

<\/p>\n\n\n

Healthy soil<\/a> is not an inert physical substance. Rather, it’s teeming with life. In fact, just one teaspoon of soil<\/a> can contain over a million microorganisms! Talk about living soil.<\/p>\n\n\n

<\/p>\n\n\n

So, why do these little organisms matter?<\/p>\n\n\n

<\/p>\n\n\n

Soil bacteria and fungi play a huge role in nutrient cycling. They convert nutrients into forms that plants can take up. Even if you apply nutrients, they might not be available to plants. Microbes help make sure plants can take up the nutrients you apply, so they don’t go to waste.<\/p>\n\n\n

<\/p>\n\n\n

They also help plants take up water. Additionally, they help ward off disease and improve soil structure.<\/p>\n\n\n

<\/p>\n\n\n

When you put all these benefits together, it means healthier plants and higher yields.<\/p>\n\n\n

<\/p>\n\n\n

Types of Soil Microorganisms<\/h2>\n\n\n

<\/p>\n\n\n

These organisms are can be broken into four main categories: bacteria, fungi, algae, and protozoa. Within each of these categories, there are hundreds of different species.<\/p>\n\n\n

<\/p>\n\n\n<\/p>\n

Soil Microbes: Bacteria<\/h2>\n

\n\n\n

<\/p>\n\n\n

Soil bacteria<\/a> are essential to plant health. With that said, soil contains both beneficial and harmful bacteria. By increasing beneficial bacteria, you can limit the harmful bacteria present in soil. So, if you’re dealing with bacterial diseases, consider adding beneficial bacteria to your soil or media.<\/p>\n\n\n

<\/p>\n\n\n<\/p>\n

Common Soil Bacteria<\/h3>\n

\n\n\n

<\/p>\n\n\n

There are thousands of species of bacteria present in the soil. These include both aerobic and anaerobic bacteria as well as rod, sphere, and spiral bacteria.<\/p>\n\n\n

<\/p>\n\n\n

However, some types of bacteria are more common in soil than others. The type of bacteria present in an area depends on factors like geography, aeration, temperature, and soil structure.<\/p>\n\n\n

<\/p>\n\n\n

It’s important to note that you can change the microbial composition of soils. By doing so, you can create a soil filled with microbes that benefit plants.<\/p>\n\n\n

<\/p>\n\n\n<\/p>\n

Beneficial Bacteria for Plants<\/h3>\n

\n\n\n

<\/p>\n\n\n

Mutualists<\/strong> form symbiotic relationships with plants. This means that the bacteria help the plant and the plant helps the bacteria.<\/p>\n\n\n

<\/p>\n\n\n

One type of mutualist bacteria are nitrogen-fixing bacteria. These bacteria convert nitrogen gas from the atmosphere into a plant-available form. In return, the plant provides the bacteria with carbon sources.<\/p>\n\n\n

<\/p>\n\n\n

Some of these bacteria live in root nodules on legume plants such as clover, peas, and alder trees. Other types of these bacteria live freely in the soil.<\/p>\n\n\n

<\/p>\n\n\n<\/p>\n

\"soil<\/figure>\n

\n\n\n

<\/p>\n\n\n

Another type of mutualist are nitrifying bacteria. These bacteria convert ammonium (NH4) into nitrate (NO3). This benefits plants because nitrate is easily taken up by most plants. However, it also easily leaches from the soil.<\/p>\n\n\n

<\/p>\n\n\n

Decomposers <\/strong>work to break down materials in the soil. These bacteria are essential to holding nutrients in the soil and making them available to plants. Furthermore, certain types of decomposing bacteria can break down toxic compounds such as pesticides<\/p>\n\n\n

<\/p>\n\n\n

How Do Bacteria Help Plants Grow?<\/h3>\n\n\n

<\/p>\n\n\n

Bacteria help plants grow in a number of different ways. One way is by changing the soil structure, another is by increasing plant growth, and yet another is by increasing nutrient uptake uptake.<\/p>\n\n\n

<\/p>\n\n\n

Improve Soil Structure<\/h3>\n\n\n

<\/p>\n\n\n

Bacteria are crucial for creating a proper soil structure. As decomposers break down larger materials to form small soil clusters called aggregates. When the number of aggregates in the soil increases, so does aeration and drainage.<\/p>\n\n\n

<\/p>\n\n\n

Increased aeration leads to increased root growth in plants. As plants’ roots grow deeper and wider, they can better reach and take up nutrients. Increased drainage further increases aeration, and water does not settle in the soil. Therefore, bacteria help inhibit the growth of harmful soil fungi.<\/p>\n\n\n

<\/p>\n\n\n

Increase Nutrient Uptake<\/h3>\n\n\n

<\/p>\n\n\n<\/p>\n

As mentioned above, soil bacteria help stabilize nutrients in the soil and convert them to plant-available forms. Without bacteria, many nutrients in the soil would be unavailable to plants.<\/p>\n

\n\n\n

<\/p>\n\n\n<\/p>\n

Protect Plants from Disease<\/h3>\n

\n\n\n

<\/p>\n\n\n<\/p>\n

Some bacteria, such as Bacillus amyloliquefaciens<\/a><\/em> protect plants from harmful microbes that cause disease. Good bacteria can protect your plants from issues such as root rot and fusarium wilt.<\/p>\n

\n\n\n

<\/p>\n\n\n<\/p>\n

Boost Plant Growth<\/h3>\n

\n\n\n

<\/p>\n\n\n<\/p>\n

Certain bacteria known as plant growth-promoting bacteria (PGPB) act as biostimulants<\/a> to increase plant growth. As the plants’ roots grow, they are better able to reach and take up water and nutrients. In turn, this further increases plant growth.<\/p>\n

\n\n\n

<\/p>\n\n\n<\/p>\n

What Types of Bacteria Help Plants Make Proteins?<\/h3>\n

\n\n\n

<\/p>\n\n\n<\/p>\n

The building blocks of proteins are nitrogen molecules. We know that nitrogen is a macronutrient that plants need in large amounts. However, not all nitrogen in soil or solution is available to plants.<\/p>\n

\n\n\n

<\/p>\n\n\n

As I’ve briefly mentioned above, certain types of bacteria<\/a> convert gaseous nitrogen into plant-available nitrogen. Some of these types of bacteria are listed below.<\/p>\n\n\n

<\/p>\n\n\n<\/p>\n
