How Does Soil Temperature Affect Plants: The Facts Explained

Spread the Word!

Soil temperature plays a very important role in the biological processes plants employ to grow and mature. 

Changing soil temperatures can alter the nutrients in the soil and the availability of water for plants.

Soil temperature affects both plant growth and development. Warmer soil temperatures promote faster germination and root development, while cooler temperatures can delay growth and increase susceptibility to diseases. Additionally, soil temperature affects the availability of nutrients to plants, as well as the activity of beneficial microorganisms in the soil. 

This article explains how the temperature of soil affects how plants function with respect to water absorption and photosynthesis, as well as how the soil itself is affected by changing temperatures.

How Does Soil Temperature Affect Plants

The soil temperature can affect the growth of plants in various ways, such as the absorption of nutrients, water, and sunlight. It affects seeds‘ germination, seedlings’ growth, and the rate at which plants use water. The chemical composition of the soil can also be affected by changing temperatures.

Soil temperature is essential for plants because it affects plant growth rate. In addition, the soil temperature helps to determine the type of plants that will grow in a certain geographic region.

Generally, the soil temperature is higher in warmer climates than in colder climates. 

This is because there are more hours of sunlight in warmer climates than in cold ones. Soil temperature also reflects the climate and topography of a certain region.

Soil temperature is one of the most important factors in plant growth.

The soil’s temperature can affect the rate of photosynthesis and respiration, affecting how much food a plant can produce.

It also affects how fast water evaporates from the soil. If the water evaporates too quickly, it will leave behind salts and minerals that can build up and inhibit root growth.

Three pertinent questions need to be answered to understand how soil temperature affects plants.

These are explained below in detail.

Ways Soil Temperature Affects Plants

The soil temperature affects the roots of plants and their ability to extract water and nutrients. If the soil is too cold, it can stunt plant growth and cause them to die.

It could also lead to rot, a major problem for plants that grow in colder climates. Plants like tomatoes, peppers, beans, squash, eggplant, and more need warmer soil to grow properly.

Soil Temperature Affect on Photosynthesis

The Process of Photosynthesis

Soil temperature affects many aspects of a plant’s life cycle, from germination to flowering to seed production. 

For example, photosynthesis is the process by which plants use sunlight to turn water and carbon dioxide into food. 

The manner in which soil temperature affects photosynthesis varies depending on the type of plant and where it is grown.

Effects of High or Low Soil Temperatures on Plants

Plants have different optimal soil temperatures for their growth and development. Some plants are more tolerant of high or low soil temperatures than others. 

Plants have to adapt to changes in temperature to grow properly. They can do this either by moving or growing faster.

The effects of high or low soil temperatures on plants can be seen worldwide as many plants live in one place all year round, while some migrate to different climates during their life cycle.

Does the Plant Type Determine its Temperature Limit

Plants are living organisms that must be kept at a certain temperature to stay alive. Different plants have different temperature limits, and they also react differently to changes in the environment.

However, the plant type does not determine its temperature limit, but it determines how it reacts to changes in the environment. 

Some plants are more sensitive to environmental changes than others and will die at lower temperatures than others. 

The plant will survive in different temperatures as long as it is within the temperature range that it is used to.

Temperature is a factor that affects the growth and health of plants. A plant’s ability to survive in different temperatures depends on its native habitat, ranging from -40 degrees Fahrenheit to 120 degrees Fahrenheit.

Does Soil Temperature Affect Transpiration and Water Movement in Plants


The soil temperature is an essential factor for plant growth. It affects the water movement in plants because of the difference in transpiration rates.

A study by the University of Washington found that plants with higher water use rates were more sensitive to soil temperature changes than plants with lower water use rates.

The study was conducted on two species, red maple, and a cottonwood tree. 

The researchers found that the cottonwoods showed little change in their transpiration rate when the soil temperature varied from day to night, but the red maples showed significant changes.

Plants need water to survive, and they can absorb it from the soil. To do so, they have developed a special system of absorbing and transporting water. 

Transport of Mineral Ions in Plants

They do this through the process of transpiration. Transpiration is when water moves up from the roots into the leaves, evaporating into vapor, which carries some dissolved minerals and nutrients with it. 

The vapor then travels back down to the roots in a process known as capillary action.

The temperature of the soil will determine how much water will evaporate from plants’ leaves and affect how much water plants can absorb. 

Transpiration rates increase with temperature because there is more energy for evaporation, so this process can transport more moisture. 

As a result, plants need less time to get their required moisture from warmer soils than cooler ones.

Do Plants Need a Specific Temperature to Flower

Flowers are the reproductive organs of plants. They are a way for plants to reproduce and spread their seeds.

Plant species have different flowering periods, and some need specific temperatures to flower.

For example, if you live in an area that is too cold outside, some plants cannot produce flowers because they need a certain temperature to produce their flowers. Therefore people often put these plants inside their homes during winter.

Some plants need a specific temperature to flower. This is because the plant needs a certain heat level to produce enough energy. 

For example, tulips will not flower if grown in temperatures below 20 degrees Celsius.

Some plants are more sensitive to changes in temperature than others. More sensitive plants will need a higher temperature for them to flower.

How is Soil Affected by Temperature

Soil is a mixture of mineral particles and organic matter. As the temperature increases, the soil’s water content decreases. 

This is because the water evaporates faster from warm soil than from cold soil. In addition, organic matter decomposes faster in warm soil than in cold soil because it needs more energy to break down.

Temperature affects the soil in many ways. It changes the soil’s chemical composition and affects the rate at which water moves through the soil. 

As the temperature increases, the water content of the soil decreases, and organic matter decomposes faster. The higher the temperature, the more water evaporates from the soil.

Temperature also affects soil because it changes the type of organisms that can live in it. For example, if the soil is too cold, then the number of organisms that can live in it will decrease.

Temperature and other factors influence the number of living organisms in the soil, such as moisture, pH levels, and air circulation. 

Different bacteria and fungi grow at different temperatures. Therefore, temperature affects the soil.

Does Soil Moisture Affect Soil Temperature


The answer to this question is yes. Soil moisture is the amount of water in the soil. Knowing how soil moisture affects soil temperature is essential because it can impact plant growth and health.

Soil moisture affects soil temperature in two ways.

  • First, it plays an essential role in the heat transfer rate from the ground surface to the air.
  • Second, it affects the rate of heat loss from the soil and its ability to absorb solar radiation and release thermal energy into the atmosphere.

The heat capacity of the soil is higher than the heat capacity of the air, so it takes longer to cool down. 

The soil temperature is also influenced by how much water is in the soil. When there is less water in the soil, it will take more time for a temperature change to be felt.

The soil’s moisture affects how quickly or slowly a change in temperature will be felt by plants and animals living on or near the ground.

The Takeaway

The soil temperature can affect plants in many ways. For example, it can affect the plant’s growth and development, as well as its health. In some cases, it can even affect the plant’s flowering time.

Soil temperature is a key factor that affects plant growth and development. The soil temperature affects how fast a seed germinates, how fast a root grows, how fast the stem grows, and how quickly the leaves grow. 

For example, plants will grow faster if they are grown in warmer temperatures than colder ones.

Soil temperature also affects plant health by causing stress to the roots, which leads to water loss or drying out of the roots in extreme cases, which can lead to wilting of leaves and death of plants. 

Soil temperatures that are too high or too low will cause adverse effects on plants because they require specific temperatures for optimal growth.

So, knowing the importance of soil temperature, you should always note it so that you can grow healthy plants on your farm.
