The Design of Dirt

Most of us take dirt for granted and perhaps even have a negative attitude toward what lies beneath our lawns and gardens. We may not realize that soil is a complex structure designed for life and that many life forms live in it. We should take a moment to consider the design of dirt.

There are many kinds of soil, and the amount varies widely in different environments. In deserts or polar areas, we find very little soil. For example, in Alaska, the soil is very thin, but life there is supported by the yearly migration of salmon. In desert areas, we may have only sand and no soil. Also, volcanic regions may have no soil since soil takes time to develop. Volcanic rock coming out of the lava flow is usually very sterile.

Because of the design of dirt, it is home to 59% of Earth’s species. Scientists have identified twelve families of living organisms that survive in the soil. Some of these are more familiar, such as mollusks, arthropods, fungi, protozoans, bacteria, viruses, plants, and even mammals. Less well-known are nematodes, oligochaets, enchytraeids, and archaes.

Humans depend on all of these life forms for food, fiber, and the survival of the animals humans use for food. Life on land could not exist without the organisms living in the soil beneath our feet. Using chemicals on soil threatens its ability to provide what we need to survive. Agriculture is moving toward more efficient and effective methods of growing our food. Efforts to duplicate the design built into Earth’s soil are proving to be a challenge.

In the Garden of Eden, everything humans needed to eat was already growing. God had designed soil that produced the plants; all the first humans had to do was gather it. When God expelled them from the garden, they were forced to deal with an Earth that was out of balance. They had to control the soil and what grew in it. We can try to copy God’s design of soil, but we are only beginning to understand how complex it is and what it takes to maintain a working environment. God’s wisdom is seen everywhere we look, even down to the design of dirt.

Soil Derived from Barren Rock

I have had the privilege of walking along a still hot lava flow in Hawaii and watching it cool and crack, exposing a red hot glowing interior. As a student of geology, I have seen the bedrock that tells of the composition of the early Earth in places throughout North and South America and England. There can be very little doubt that the creation of planet Earth left a ball of sterile, barren rock orbiting the Sun. Having lived for 85 years on this planet, I have had the joy of seeing soil derived from barren rock supporting vast plant and animal life.

The story of how soil is produced is a story of wisdom and design unique to our planet. Therefore, it is essential that we understand the importance of the soil God gave us and how to take care of it in our age of expanding populations.

National Geographic published an excellent article by Ferris Jabr titled “Out of Sight,” containing pictures by Oliver Meckes and Nicole Ottawa. The pictures show the agents God created to convert the barren rock of our planet into soil that can grow a forest. A single gram of forest soil (1/454th of a pound) can contain as many as a billion bacteria, a million fungi, hundreds of thousands of protozoa, and nearly a thousand roundworms. The pictures of those microscopic organisms are incredible.

Soil derived from barren rock began with fundamental processes caused by rain, wind, and ice. Once the elements broke down the rocks to small sizes, the microscopic living organisms went to work. Microbes, fungi, lichen, and tiny plants broke down the sand-size rocks and enriched them with minerals life could use. In Hawaii, you can see the black sand beaches produced in modern times and the places where those agents have processed soil in which plants can live. Over time, the elements in early soils, such as carbon, phosphorus, and potassium, were processed to produce advanced soil structure.

The Genesis creation account does not explain God’s methods of preparing the planet for human life. Proverbs 8:22-36 finds Wisdom narrating the processes of creation. But even Wisdom can’t describe the process of soil derived from barren rocks to people with no microscopes or technical language. Today, we are uniquely privileged to see God’s handiwork and to marvel at the incredible complexity involved in the creation of dirt.

God’s Rototiller the Lyrebird

One of the less known necessities of the natural world is the need to aerate the soil. Without some device to rototill your gardens, the ground would be so hard nothing could grow in it. Worms, moles, groundhogs, and insects work the ground so plants can grow, but the world’s most efficient agent to do this is God’s rototiller, the lyrebird.

These birds of eastern Australia have rake-like feet that are so strong they can crush scorpions. Lyrebirds do more than any other form of life to till the soil. One lyrebird can turn over and aerate 388 tons of material on the ground every year while reducing fire risk. Lyrebirds eat insects that they kick up as they work the soil, reducing the danger of insect infestations.

Humans have learned what it takes the get the soil to yield its best crop. We plow and disk the ground to prepare it for producing plants that give us our food. God’s rototiller, the lyrebird, does it more efficiently by controlling even the pests that would defeat our efforts. The natural world continues to reveal God’s design in ways that we are just beginning to understand.

Bacteria Working Together

Bacteria are single-cell microorganisms that we do not think of as having social behavior. However, scientists are studying Myxococcus xanthus bacteria working together. They are rod-shaped bacteria that live in the soil and organize into structures of thousands of cells to hunt food or to survive when food is not available.

Myxococcus xanthus bacteria are predators that eat other microbes. When they organize into 3-D structures, they can be visible to the naked eye. In this complex form, they swarm toward their prey in a single mass of bacteria working together in “ripples.” You can see them on the left side of the picture.

To capture their food, the swarms of Myxococcus xanthus microbes secrete enzymes that kill and digest the prey and then take in their nutrients. These predator bacteria hunt together because individually they can’t produce enough of the antibiotics to kill the prey, but together they are deadly to other microbes.

When there is a food shortage, scientists still find these bacteria working together to survive. They form a structure called “fruiting bodies” as pictured on the right. In that form, they can survive for years if necessary. As single cells, they would not survive.

Studying how these microbes work can help scientists design new antibiotics or pest-resistant seeds for agriculture. Myxococcus xanthus rods are alive and can crawl, so their movement applies the laws of physics and the biological laws that govern living things. Studying these bacteria may help materials scientists gain new ideas for constructing liquid crystal display screens in electronic devices.

We learn much by looking at what is functional in the natural world. A wonder-working hand has moved before us and gives us tools for developing new materials to improve our lives. Also, bacteria working together can serve as a lesson to remind us that humans can accomplish more when we work together.

Good Soils Are Vital for Survival

Many years ago in Alaska, I had a discussion with a biologist who was studying the Alaskan soils. His study revolved around the fact that Alaska has very little soil and what it does have is developing. The lack of soil in Alaska has limited plant growth and made the ecology dependent on migrating salmon. Soils are complex mixtures of organic matter, minerals, water, air, and billions of organisms that form over hundreds of years. Good soils are vital for survival. President Franklin D. Roosevelt once said, “A nation that destroys its soils destroys itself.”

Research has shown that plants are designed to “call” for nutrients from the soil. A plant will release molecules called flavonoids, which cause bacteria in the soil to migrate into the plant and form nitrogen nodules on the roots. The nitrogen nodules generate food for the plant. If ample nitrogen is already available for the plant, it will not release the flavonoids.

This “hunger” by plants is vital to understand because many natural and human-caused processes can deplete the soil. Forest and brush fires, hurricanes, pollution, and climate change can deplete soils’ nitrogen content and kill plants. Studies of the giant sequoias in California have shown that the soil under them has twice as many bacteria as the soil under nearby sugar pines. We all know that bacteria influence human health, but bacteria also affect plant health and growth.

As our population increases and world climates change, it will become increasingly important to understand how soil allows us to feed our growing population. God’s design of the Earth includes providing the soils necessary to produce food. Good soils are vital for survival.

Why We Need Lightning

Why We Need Lightning All life forms on planet Earth need nitrates to build proteins and DNA. We get our nitrates from the plants and seeds that we eat. Plants absorb nitrates from the soil through their roots. The nitrates in the soil come from rain that has absorbed nitrates from the air through which it falls. The nitrates in the air come from the action of lightning. Our atmosphere is 78% nitrogen, and lightning takes some of the nitrogen and catalyzes it into a bond with oxygen to make nitrates. That is why we need lightning.

A surprising thing about this complex system is that the lightning is far more abundant than we realize. Lightning strikes the Earth around 1000 times every second. Above the clouds, in the upper atmosphere, there are continuous lightning types that we don’t see from Earth’s surface. They are called elves, sprites, blue jets, and gigantic jets, depending on their color and shape. There is a voltage difference between the ground and the ionosphere, which varies from 200,000 volts to 500,000 volts. Even in fair weather, there is a constant flow of current, which scientists believe is caused by the spinning of Earth’s core. All of this adds up to a total of over three million lightning strikes a day, and each produces nitrates to sustain life. The jet stream carries these nitrates around the planet, providing a natural fertilizer in places where electrical storms rarely occur.

The Old Testament contains suggestions of this being a part of God’s design for life on Earth. Ecclesiastes 1:6 talks about wind patterns, and Jeremiah 10:13 speaks about lightning. Job 36:29 and 37:21 speak of clouds and bright lights. Lightning is sometimes destructive, often because of foolish construction by humans or ecological problems caused by human mismanagement. In reality, lightning is a tool God uses to build and maintain life on Earth. That is why we need lightning. The more we learn of the creation, the closer we get to the Creator.

Soil Studies Speak of God’s Preparation for Humans

Healthy Soil
There is an economy of language in the Hebrew descriptions of the Bible. In Genesis 2:8-9 for example, the Bible says: “Now the Lord God had planted a garden in the east, in Eden; and there he put the man he had formed. The Lord God made all kinds of trees to grow out of the ground…”

We can learn a lot from those verses. They tell us that the Lord planted something, he did not “zap” something into existence. Later the man was told to tend the garden (verse 15), suggesting that it needed care to continue to provide for the man’s needs and later for the woman’s needs. How long was it after God planted the trees before they began to produce fruit? What did Adam and Eve have to do to take care of the garden? How long was it before Adam and Eve sinned? What else did God need to do in the process of planting the trees?

This last question opens the door to a great deal of understanding that science has gained in recent years through the study of soil chemistry. Plants do not grow in sterile sand. For soil to nourish plants so that they can feed us, much careful science has to be applied. Modern soil scientists refer to “healthy soil” meaning that it is rich in organic material, is crumbly, and has the right chemical profile. To have these things, the soil must contain microbes including bacteria, fungi, nematodes, and protozoa. A teaspoon of healthy soil can hold more microorganisms than there are people on Earth.

We now know that there is a symbiotic relationship between plants and soil microbes. Plants use the sun’s energy to pull carbon dioxide from the air and create a carbon-rich nutrient packet to allow growth. Oxygen is released in that process. The plants also leak nutrients to the microbes, and the microbes supply plants with other nutrients they have extracted from the minerals in the soil. The fungi produce an underground network that brings water and carbon to the plants. When insects begin to feed on a plant, fungi filaments called hyphae help the plant bring tiny soil nematodes that feed on the insects.

When humans abuse the soil and interrupt this system, we have to artificially add chemicals to do what organisms in the soil were designed to do. The chemicals of modern farming could be reduced or eliminated if farmers worked on building healthy soils. The Garden of Eden was a place of healthy soil. God used incredible wisdom and intelligent design to build a system that would meet human needs. This was done in God’s time and was not a magic show, but a consciously built system that has sustained all living things for a very long time. Proverbs 8:22-31 tells us that wisdom was involved in all of this planning and design, and Romans 1:18-22 lets us know that all of this is a testimony to the existence of God.

There is a wonderful article in the April/May 2017 issue of National Wildlife page 35 (available online http://www.nwf.org/News-and-Magazines/National-Wildlife/Gardening/Archives/2017/Soil.aspx) that documents all of this and shows us the complexity of God’s soil science.
