Plant Nutrients and Soil Nutrients

Gardening can be an incredibly relaxing experience, as long as you know what you’re doing. There are a few factors that you have to keep a close eye on to ensure your plants grow healthily.

So, if you’re interested in finding out more about plant nutrients and soil nutrients, you’re in the right place. 

Let’s dive into everything you’ll need to know to grow a beautiful garden.

Why Is Soil Nutrition Important?

At first glance, soil looks like an inanimate object with not much going on. However, this couldn’t be further away from the truth.

When you put a sample under the microscope, you’ll quickly find out that the substance is its own ecosystem.

It contains hundreds of organisms that work together to maintain a healthy environment. 

These tiny creatures can break down compost material into minerals and vitamins. That creates a fertile base for many other living beings to grow, mainly plants.

Florae depend on the nutrients in the soil to grow healthily. Without them, plants wouldn’t be able to gather sunlight. 

This will significantly impact their ability to turn light into energy using photosynthesis.

Let’s take a look at some of the key roles of the growing medium.

The main function of soil is that it provides a suitable habitat for a variety of species. That includes a few burrowing mammals and microorganisms like bacteria.

Other than that, the growing medium is excellent at recycling raw materials. It can turn waste animal and plant by-products into nutrients.

Finally, soil nutrition is crucial for growing plants.

What Are Soil Nutrients?

There are many nutrients that make up the building blocks of soil. These are minerals and vitamins that plants use to carry out basic life functions.

A few of the major nutrients include nitrogen, phosphorus, and potassium. Each one of these will play a primary role in keeping florae healthy. 

For example, some of the minerals will help with growing strong stems and leaves. Other than that, a couple of vitamins will focus on giving the plants their signature green color.

Moving on, soil nutrients will aid in maintaining the ecosystem in the growing medium. They’ll affect the pH, which is crucial for keeping microorganisms alive. 

That means that not only do you need the right nutrients in the soil, but also the correct concentrations.

In addition, minerals and vitamins can change the texture of the soil. Depending on the nutrients present, the growing medium’s moisture retention will change.

That means the water level in the soil is proportional to the nutrient concentration.

What Nutrients Do Plants Need?

There are a few nutrients that plants need, including nitrogen, phosphorus, and potassium. These are the basic building blocks that go into the main structure of florae.

Although, these are far from the only nutrients that plants need. The nutritional needs of foliage will differ from one species to another.

For instance, chlorine is a mineral that is crucial for plant growth. It plays an active role in many physiological metabolism processes.

The mineral boosts disease resistance and tolerance. In addition, chlorine is responsible for regulating the water content in plants.

As we all know, plants have different watering needs. Some, like Lily of the Valley, need plenty of moisture. That means they’ll want a high concentration of chlorine in the soil.

On the other hand, drought-tolerant florae only need trace amounts of the mineral. A great example of this is the cacti family.

Microorganisms and Soil Health

Microorganisms are an essential part of our world. Even though we can’t see them with the naked eye, they’re around us all the time.

In soil, bacteria and fungi play an important role. They’re responsible for breaking down organic matter into minerals and vitamins.

This gives plants and other tiny creatures in the growing medium the nutrients they need. 

On top of that, microorganisms are excellent at purifying their surroundings. They can digest gasses like nitrous oxides. 

These can be toxic to both humans and plants in high concentrations.

In addition, bacteria can help break down carbon dioxide, which is a greenhouse gas. 

So, not only do microorganisms keep the soil healthy, but they also help the environment.

What Are Essential Plant Nutrients From Soil?

There are many elements that go into making soil. So, let’s take a look at some of the major components and what role they play in soil health.

Nitrogen (N)

Even though there are many minerals in soil, nitrogen is arguably the most critical one. That’s because most plants rely on the element, with the exception of a few florae.

Nitrogen is one of the main parts of chlorophyll, which allows plants to absorb sunlight. In addition, it’s what gives the foliage its bright, green shade.

Other than that, nitrogen also makes up the majority of amino acids. These are the components that go into the structure of all proteins.

A few people are aware that plants rely on proteins just as much as humans do. They use the compound to produce new structures like leaves and stems.

Plus, proteins are crucial for the production of enzymes.

Finally, nitrogen will play a role in DNA formation. It’s a necessary component of the genetic materials that allow plants to grow and reproduce.

Phosphorus (P)

Phosphorus is another mineral that goes into the production of DNA. It helps nucleic acid stabilize and stay healthy for longer. 

This allows plants to use nitrogen in protein synthesis. For that reason, the element is important for cell division and the creation of new tissue.

On top of that, phosphorus aids with complex energy transformations. It makes it easier for plants to break down sunlight into energy. 

This will result in excellent root growth, increased winter hardiness, and speedy maturity. Plus, phosphorus makes it possible for plants to grow new side shoots or tillering.

These are especially useful for seedlings.

Without the element, you’ll notice that plants will look a little spindly and frail. They may also have grayish-green leaves and a reddish hue near the base of the foliage. 

Once a plant reaches this state, it’s difficult to rejuvenate it. We can try adding phosphorus supplements, but as soon as all the leaves turn gray, it’s too late.

Potassium (K)

Potassium has a couple of different responsibilities when it comes to plants. 

For starters, the element is in charge of regulating water movement. To help you understand this, let’s take a quick look at the composition of leaves.

At first glance, they look like flat green structures. However, if you zoom in on the surface, you’ll see many small openings called stomata.

These allow water vapor to move in and out of the leaves easily. Although to ensure that plants don’t lose too much moisture, potassium will stand guard at the gates. 

It’ll let the florae know when it’s ok to open up the stomata and let water out.

Potassium is also involved in enzyme activation. The element will decrease the energy needs and help break down and absorb minerals.

Besides that, potassium is a key part of the reaction that produces energy in plants. 

Without sufficient concentrations, florae will wither, turn yellow, and have stunted growth patterns.

We call potassium a macronutrient because plants tend to consume a large amount of it. 

Calcium (CA)

Plant cells have a special layer known as the cell wall. This is the outermost part, and it provides structural support to the cells.

Calcium is one of the chief components that go into making this section. It’s a requirement that gives cell walls their rigidity and stability.

In addition, calcium ions have a positive charge inside plants. So, they can attract negative ions into the cells, and repel other positive charges.

This allows the mineral to maintain the electrolytic balance of the organism. In simple terms, the element aids in deciding what goes in and out of the cells. 

Luckily, calcium is relatively abundant in most soil environments. For that reason, mineral deficiency is highly unlikely. 

Sadly, too much of the element can become a problem. It’ll affect a plant’s ability to regulate the materials going in and out through the roots.

This will cause the flora to wilt and fade away.

Magnesium (MG)

Magnesium is the central component of chlorophyll. It’s the portion of the plant cells that is responsible for collecting sunlight.

As you can imagine, that makes the mineral critical for florae survival.

Moving on, just like some of the other nutrients on the list, this one will aid in enzyme activation. It’ll allow the proteins to attach to large molecules and break them down.

In addition, the element can make it easier for plants to produce new protein molecules.

Other than that, magnesium will act as a phosphorus carrier. This means it’ll bind to the second element and help it move around the plant’s transportation system.

For that reason, without the mineral, plants will struggle to grow. They won’t be able to collect any sunlight for energy.

On top of that, the florae can’t make use of the other minerals in the soil.

The early signs of magnesium deficiency include drooping, yellowing, and stunted growth. 

Sulfur (S)

Last, but certainly not least, let’s take a look at the functions of sulfur in plants. First and foremost, the mineral’s main job is to aid in the formation of amino acids.

This will make producing proteins in the future much faster.

Next, sulfur can promote the production of certain oils and enzymes. These will coat the outside of plant leaves and create a waxy layer.

In the summer, this outer shell will provide protection from sunlight. It limits the amount of water evaporation through the leaves.

As for the winter, the waxy layer will keep the leaves bendy enough to avoid breaking in the frost.

Aside from that, sulfur is also a main ingredient in nodulation. This process allows plants to exchange substances through their roots underground.

Lastly, the mineral has a close connection to nitrogen. Without it, plants won’t be able to regulate their mineral concentration.

So, not only will sulfur help keep florae safe, but it’s also instrumental to survival.

Soil Nutrition and Gardening

The key to successful gardening starts with a healthy base. As you can guess, that means that without healthy soil, we wouldn’t have any of the florae we do today.

So, let’s take a look at how the growing medium will affect your gardening.

Soil Nutrition and Plant Health

There are many factors that go into keeping a plant healthy. Some of the major ones include overall temperature, moisture concentration, and sunlight level.

While all these aspects seem disconnected, soil can tie them all together.

The nutrient content of the growing medium will change how it behaves. For example, with a balanced mineral concentration soil is able to retain a lot of water.

This is the main source of moisture that plants rely on.

Other than that, the nutrients in the soil will affect how much heat the ground absorbs. If there aren’t enough minerals in the medium, the earth will heat up a great deal faster.

That makes it much more difficult to control the internal temperature of the plants.

Finally, the soil needs to be sturdy enough to anchor and stabilize the florae. This will allow the foliage to grow in the direction of the sun to gather light.

Soil Nutrition and Potting Mix

Most people think that soil and potting mix are different names for the same substance. However, that’s not quite the truth.

Soil is usually a mixture of organic materials like sand and clay. This makes it ideal for growing an ecosystem and plants.

On the other hand, the potting mix doesn’t contain any of these components. Instead, it’s mostly made up of vermiculite, bark, perlite, compost, and moss. 

That makes for a sterile environment that doesn’t promote the growth of any harmful bacteria.

Since they have different properties, each medium is better suited for specific applications.

Soil is best in a wide, open space, with plenty of room for sunlight and water to pass through. As for the potting mix, its ideal use is in small containers and tight spaces like planting boxes.

The only thing soil and potting mix have in common is that they can grow plants. Both mediums should contain everything florae need to develop healthily. 

Soil Nutrition and pH Levels

pH is the measure of the acidity of an object, meaning it can tell you if something is an acid or a base. It’s one of the easiest ways to identify whether the soil is healthy or not.

This is because each nutrient will affect the pH of the soil in a specific way. So, if you measure the overall pH, it can tell you if the growing medium is off balance.

For example, nitrogen has an average value of around 5.5. This will result in your soil being slightly more acidic than it should be.

So, the solution to that is to add a bit of calcium, which has a pH of 7.5. These will balance each other out and give you a stable growing medium.

Ideally, soil pH should be around 6.0 or 7.0. That’s a neutral environment that can support the growth of a large variety of plant species.

Soil Nutrition and Soil Types

The type of soil you use will affect its ability to dissolve and retain nutrients. To help you understand this, let’s take a look at the most common medium types.

Sandy

As the name suggests, the main ingredient in this medium is sand or tiny weathered rocks. That means the particles in the soil are quite large, which creates giant pores. 

These will allow water to move freely through the soil. This is especially useful if you live in a damp area.

The medium will be able to regulate the heavy moisture flow and keep your plants healthy. That’s an excellent way to avoid diseases like root rot from developing.

Clay

Clay has much finer particles than sand, meaning it also has smaller pores. This makes it the densest type of soil on our list.

The medium is exceptional at retaining moisture and can stay damp for days on end. Sadly, since water can’t travel easily through this soil, neither can minerals.

That means clay soil isn’t all that fertile.

Silt

Silt is in a happy medium between sand and clay when it comes to particle size. That means it gets the best of both worlds.

This is probably why silt soil tends to be the most fertile variety.

Loamy

Loamy is a combination of all the previous types of soil on our list. It maintains some of the sandy medium’s ability to drain water with clay’s dense nature.

This makes for a stable mixture that can support a variety of plant species. Even though silt is more fertile, loamy is much easier to use and maintain.

Soil Nutrition and Soil Fertility

Soil fertility will determine how likely plants are going to grow in the medium. This is directly proportional to the level of minerals in the mix.

Without the proper nutrients, all soil is infertile. The medium won’t be able to support the growth of any plants. 

How to Improve Soil Health for Gardening

The easiest way to improve the health of soil is to ensure it has all the basic building blocks for plants.

That includes:

• Sufficient moisture
• Adequate sunlight
• Proper temperature

These should ensure the soil is a hospitable environment for most plants.

It’s also a good idea to boost the mineral concentration in the medium. You can do that by sprinkling a little fertilizer on the surface. 

How to Test for Soil Nutrition for Gardening?

The most accurate way to test soil is to send a sample to a local lab. There a specialist should be able to tell you the exact concentration of each mineral.

While this works great, it can be a little time-consuming and a tad expensive. 

Other than that, to test soil health, you can measure the pH. Using an at-home test, determine the pH of the soil and ensure that it’s around 7.0.

All you have to do is plant the tester in the ground and wait for it to display a reading. 

If the reading isn’t neutral, then you can add nitrogen to decrease the pH and sodium to increase it.

However, this may lead to the over-saturation of a specific mineral. So, it’s best to use a prepackaged fertilizer to avoid throwing the medium off balance.

Does Performing Soil Amendments Improve Soil Nutrients?

Soil amendments are substances that we add to the medium to boost its properties. 

Some examples like coconut coir can alter the texture. It’ll soften the growing medium and enhance its ability to collect water.

This will make it easier for nutrients to dissolve in the soil, where plants can absorb them.

Moving on, some amendments can alter the pH of the medium. As we mentioned before, this will have an effect on the nutrient concentration of soil.

Besides that, amendments like fertilizers and compost directly increase the level of minerals. This will make for a much more hospitable environment for florae to grow. 

FAQS

What Is Soil Exhaustion

The simplest way to describe exhaustion is when soil is no longer able to support plant growth.

This can be because of a textural issue where the roots can’t anchor to the ground. You can fix this by adding a few amendments to correct the consistency.

Aside from that this may be because of nutrient depletion. Once soil runs out of minerals, florae will stop growing and can fade away completely.

What Causes Soil Exhaustion?

There are many culprits behind soil exhaustion. These include:

• Erosion
• Pollution
• Overwatering
• Lack of crop rotation

To ensure that doesn’t happen to your soil, you need to cycle through crops every season. Other than that, it’s also a good idea to regularly fertilize the growing medium.
