Unveiling the Hidden Threats to Our Earth's Foundation

Where Has All the Soil Gone?

Hello, plant parents! It’s no secret that we love our green (and pink, and purple, and yellow, and really the entire rainbow) plant friends and want to make sure they have a happy and healthy place to call home. Sun and water are not the only things plants need to thrive. They also need nutrients which they get from soil.

The Dirt-y Truth

As plant parents, we know that soil is the foundation for healthy and flourishing plants. It provides essential nutrients and a stable environment for our leafy friends to grow. However, have you ever wondered why all the soil seems to disappear and your plants need to be topped off with new soil? Where has it all gone?

In order to answer that question, we need to understand a little about soil and its importance to plant health. Soil is a mixture of organic and inorganic materials, including a variety of minerals, water, air, bacteria and fungi. It’s the primary medium that plants rely on for strength, water, and food.

Soil nutrient loss is a gradual process that occurs when essential minerals are removed from the soil. This happens due to natural processes like erosion or leaching or even human activities like monocropping or continuous cropping. The problem with nutrient loss is that it results in nutrient deficient soil. Which hurts a plants’ growth and leads to soil degradation.

How Does Soil Lose Its Nutrients?

By understanding how soil loses its nutrients, we can take steps to prevent it. And maintain healthy soil for our plant babies. So, what are some of the leading causes of nutrient depletion in soil?

Leaching – The Culprit of Nutrient Loss: Leaching is a natural process where nutrients in the soil are carried away by water. This happens when water moves through the soil and takes nutrients with it. Rain, irrigation, and other types of water application techniques all contribute to the leaching process. Although it’s a natural process, over-irrigation can exacerbate the problem. When too much water is applied, the excess water will leach out the nutrients that plants need, leaving the soil nutrient depleted.
Soil Erosion – A Slow but Steady Killer: Soil erosion is the natural process of soil being moved or carried away by wind or water. While this can happen naturally, it can also be accelerated by farming practices like plowing and tilling. When topsoil is removed, the nutrients that were once present in that soil go with it. Soil erosion can be a slow but steady killer of soil fertility. And it can take years or even decades for the effects to become apparent. But it does happen, and plant parents need to be aware of it.
Monocropping – The Practice of Growing the Same Crop: Monocropping is the practice of growing the same crop in the same field year after year. This depletes the soil of certain specific nutrients, such as nitrogen, and increases the likelihood of pests and diseases. When the same crop is grown repeatedly in the same field, it will use up the nutrients that the crop needs and eventually completely deplete the soil of those nutrients. This can also cause an imbalance in the soil microbiome, making it more susceptible to pests and diseases.
Continuous Cropping – Give the Soil a Break: Continuous cropping is the practice of growing crops in the same field without giving the soil a break or rotating crops. This can lead to nutrient depletion, soil compaction, and increased pest and disease pressure. When soil is continuously cropped, it doesn’t have a chance to recover from the previous crop’s nutrient uptake. Soil compaction can occur when heavy machinery is used repeatedly on the same soil, making it more difficult for water and nutrients to penetrate the soil.
Change in pH – The Soil’s Acidity and Alkalinity Levels: A change in soil pH can affect the availability of essential nutrients for plants. Soil with a high pH can limit the availability of nutrients like iron. While soil with a low pH can limit the availability of nutrients like calcium. When the soil pH changes, it can affect the soil’s ability to hold onto nutrients, making it difficult for plants to access the nutrients they need.
Burning of Crops – Releasing Nutrients into the Atmosphere: Burning crop residues can release essential nutrients into the atmosphere, reducing the amount of nutrients available in the soil. While burning may be an effective way for many people to manage crop residues, it’s important to be mindful of the nutrients that are being lost. Burning can release nitrogen, sulfur, and other important nutrients into the atmosphere. Making them unavailable to the plants that need them.

As you can see, there are several ways that soil can lose its nutrients. Leaching, soil erosion, monocropping, continuous cropping, changes in soil pH, and burning of crops can all contribute to nutrient loss. As plant parents, it’s important to take steps to prevent these causes and maintain healthy soil for our plant kids.

Ways to Prevent Nutrient Loss in Soil

Soil nutrient loss has a significant impact on plant growth and health. Fortunately, there are several ways to prevent nutrient loss in soil and ensure that your plants have the nutrients they need to thrive.

Use appropriate fertilizers in adequate amounts: One of the easiest ways to prevent nutrient loss in soil is to add nutrients back into the soil using fertilizers. However, it’s important to use appropriate fertilizers in the right amounts. Using too much fertilizer can actually have a negative impact on soil health and plant growth. Over-fertilization can alter the pH of the soil, which can cause further nutrient loss. One perfect choice for most indoor plants is Dyna-Gro Foliage Pro Plant Nutrition from PLANTZ. This complete formula has all six essential macronutrients and 10 micronutrients for optimum plant growth in any medium. Finally, always read the labels on fertilizers and follow the recommended application rates.
Apply fertilizers at the right time: In addition to using the right amount and proper type of fertilizer, it’s important to apply fertilizers at the right time. Applying fertilizers when heavy rains are expected can lead to leaching of the nutrients. Which defeats the purpose of adding them to the soil. It’s best to apply fertilizers when the weather is dry or when light rain is expected. Plus, those heavy rains will wash the fertilizers away into ponds, lakes, and streams which can wreak havoc on an ecosystem.
Make wetlands or filter beds to recover nutrients: Wetlands or filter beds can be used to recover nutrients from runoff or drainage water. These areas are designed to capture and filter water. Allowing nutrients to settle at the bottom where they can be reused. Wetlands and filter beds can be particularly effective in agricultural areas where large amounts of water are used for irrigation.
Apply fertilizers according to the needs of the soil: Different types of plants require different types of nutrients. And soil conditions can vary from one location to another. To ensure that your plants have the nutrients they need, it’s important to apply fertilizers according to the needs of the soil. This means getting your soil tested for pH and nutrient levels so that you can choose the right fertilizer for your plants.
Compost: Composting is a great way to recycle organic waste and add nutrients back into the soil. Composting involves collecting organic materials like leaves, grass clippings, and food scraps, and allowing them to decompose over time. Once the compost is ready, it can be added to the soil to improve its nutrient content.

Preventing nutrient loss in soil is essential for ensuring healthy plant growth. By using appropriate fertilizers, applying them at the right time, creating wetlands or filter beds, applying fertilizers according to the needs of the soil, and composting, you can help to maintain the health of your soil and ensure that your plants have the nutrients they need to thrive.

Reviving Old Soil

You may find yourself faced with the challenge of reviving old soil for your plants. Over time, soil can become depleted of nutrients, compacted, and lacking in the organic matter that plants need to thrive. Fortunately, there are several ways to renew old soil and replenish the nutrients your plants need to grow strong and healthy.

Blend with fresh soil: One of the simplest ways to revive old soil is to blend it with fresh soil. Adding fresh soil to your old soil will help to increase its nutrient content, as well as improve its structure and water holding capacity. When blending old and new soil, it’s important to mix them thoroughly to ensure that the nutrients are evenly distributed. A good rule of thumb is to use a 1:1 ratio of old soil to new soil. Although this can vary depending on the condition of your old soil.
Mix in more nutrients: Another way to revive old soil is to mix in more nutrients. This can be done by adding organic matter like compost or aged manure to your soil. Organic matter is a rich source of nutrients like nitrogen, phosphorus, and potassium, as well as other micronutrients that plants need to grow. To add organic matter to your soil, simply mix it into the top layer of soil with a garden fork or tiller. Aim to add about 1-2 inches of organic matter to the top layer of soil, and then mix it thoroughly.
Compost the soil: Composting your old soil is another effective way to renew it. Composting involves breaking down organic matter like leaves, grass clippings, and kitchen scraps into a rich, nutrient-dense soil amendment. To compost your old soil, start by adding organic matter like leaves, grass clippings, and kitchen scraps to a compost bin or pile. Add a layer of old soil on top of the organic matter. And then repeat this process until the bin or pile is full. Over time, the organic matter will break down into compost, which can then be mixed back into your soil. Composting your old soil is a great way to improve its structure and nutrient content, while also reducing waste.
Add water: Finally, adding water is a simple yet effective way to revive old soil. Soil that is dry and compacted can make it difficult for plant roots to access the nutrients they need to grow. By adding water, you can help to loosen the soil and make it easier for plants to absorb nutrients. To add water to your soil, simply use a watering can or hose to saturate the top layer of soil. Aim to water deeply and infrequently, rather than giving your plants frequent shallow waterings. This will encourage plant roots to grow deeper into the soil, where they can access more nutrients and water.

Reviving old soil is an important part of plant care, and there are several ways to do it effectively. By blending old soil with fresh soil, adding organic matter, composting, and adding water, you can improve the structure and nutrient content of your soil. And give your plants the best chance to grow strong and healthy. Remember to always test your soil’s pH and nutrient levels before making any changes. And consult with the experts at PLANTZ if you’re not sure where to start. Happy gardening!
