Soils Matter, Get the Scoop!

Since the beginning of agriculture, people have recognized that a sufficient water supply is essential for crop production. The capacity of soil to store and supply water for plant growth is a fundamental agroecosystem service. It also is a soil health indicator. How well this soil water storage function performs affects To understand soil water … Continue reading What affects how well soil holds…

Pores are in almost everything. Look closely enough and you will find them in the wood and bricks of buildings, your skin, and the ground beneath. Soil pores are the spaces between Earth’s solid pieces (rocks, sands, silts, clays, and organic matter). Some pores are isolated and surrounded by solids on all sides, like a … Continue reading What are soil pores?

Most people rarely think of the thousands, if not millions, of living things they step on every day. Soil mesofauna are the tiny arthropods that live beneath our feet, ranging in size from 100µm to 2mm, which is comparable to a grain of salt. This intermediate size category of soil arthropods includes microarthropods, a group … Continue reading How do soil microarthropods affect crop production?

One of the most important jobs for a grower is managing water. Some areas of the United States have plenty of rainfall throughout the growing season. Others do not. And still others have too much water at some times of the year and not enough water at others. All of these different farm fields need … Continue reading What is controlled drainage and subirrigation?

Scientists call the region between the soil surface and the groundwater table the vadose zone. It also is often called the unsaturated zone. This zone comprises soil and underlying sediments or bedrock that lie above the groundwater table. The vadose zone contains “the living skin” of our planet, that is, the outermost layer of Earth … Continue reading What is the Vadose Zone?

In a word, yes, the type of soil on the baseball field greatly affects how players perform! Professional baseball fields are built from many types of soil. You might never guess that beneath the athletes’ feet is a precisely-engineered mixture made of multiple components. We call these materials “engineered soils.” Engineered soils are designed and … Continue reading Does the soil on a baseball f…

Since the mid-19th century, increasing temperatures have resulted in the retreat of mountain glaciers on all continents. When glaciers retreat, they leave “glacial debris.” This debris serves as new substrate for soil and ecosystem development. This is often called “parent material” in the process of soil formation. The glacial debris is initially loose material, which … Continue reading How did …

Tidal marshes are wetlands that are covered with incoming tidal water twice a day. These marshes may be as small as narrow fringe along a tidal creek or miles across in estuaries with adjacent flat landscapes. There are nearly 40 million acres of tidal marshes along the Atlantic, Gulf, and Pacific shores of the US. … Continue reading How do tidal marshes store carbon?

Agriculture is essential to ensuring global food security. However, the agricultural industry is also one of the largest sources of greenhouse gas emissions. Some agricultural practices can release carbon dioxide, nitrous oxide and methane into the atmosphere. Incentivizing climate-smart farming practices by creating “soil carbon credits” is one way to reduce the impact of agriculture … Continue …

We explored how coastal areas are capable of storing carbon at a great capacity in a recent blog. The Everglades in southern Florida are also known as a reserve of carbon storage. Some areas of the Everglades have “tree islands” and a recent study showed they are capable of storing more carbon and other nutrients … Continue reading What is a tree island, and how does it help with carbon storage?

“Blue carbon” is a term for carbon captured by the world’s oceans and coastal ecosystems. Mangrove forests, tidal marshes, and seagrass beds are the main vegetated coastal areas that store vast amounts of blue carbon. It’s not really blue – it’s named after the color of the ocean. But blue carbon is an important tool … Continue reading What is blue carbon, and why is it important?

Cities can have many benefits when designed well, including reducing carbon imprints. Another way cities can improve their environmental impact is by using “low-impact development” with regard to water management. Also called “green stormwater infrastructure,” it provides planners with a toolbox of practices and approaches to manage water during rain events and snowmelt. On undeveloped … Continue…

In order to grow well, plants need a place to grow, access to nutrients, and in most cases sunlight. A rich soil provides that home and a good supply of nutrients. But young soils have less to offer – yes, soils can have different ages ranging from hundreds to thousands to millions of years old. … Continue reading How does young soil support plant life?

Minimizing soil disturbance is one of the key tenets promoted to build soil health in agricultural systems. Many farmers across the county have adopted reduced and no-till systems to build soil carbon, a central component to healthy soils. But what if you grow a crop where the part you sell is underground – like potatoes? … Continue reading How can we improve soil health in potato cropping system…

Have you ever wondered about the living organisms in the soil? Let’s dig into the soil today and meet our very special friend. We will be learning about the secret abilities of this friend and how this tiny friend shows friendship to us. Our friend has a cool Latin name “Trichoderma.” Trichoderma is a genus … Continue reading What is Trichoderma and how is it beneficial?

Lawns are a major part of urban ecosystems. Turf grasses represent one of the major crops in the United States. The area of lawns combined would be about equal to the size of the entire state of Wisconsin. Lawns have several environmental benefits, including carbon sequestration, reducing urban heat, and reducing. However, if they are … Continue reading How can I manage my lawn to prevent nitrate…

In a word, yes! In a paper published in the Journal of Environmental Quality (2021), researchers studied a type of submerged aquatic moss. Fontinalis antipyrectica has a common name of “willow moss” and can even be installed in home ponds. Willow moss is a species in the class Bryopsida, which includes over 11,000 moss species around … Continue reading Can moss help clean up waterways?

Improving soil health on farm fields integrates the three types of soil management: physical, chemical, and biological. Physical management includes how farmers use their equipment on fields – tilling, harvesting, etc. Chemical management involves the timing and choice of fertilizers, manure, and other additions. Soil biology is the next frontier being researched for optimizing soil … Continue re…

As the name implies, “Dead Zone” is an area with no living beings. When a dead zone occurs within a waterbody, that zone has no aquatic life. Dead zones can be found around the world. They are a problem for coastal waters, bays, and lakes. The Clean Water Act was passed in 1972, and is … Continue reading What is a dead zone?

Soil moisture is key to understanding the land’s surface and all the activities that occur there, both seen and unseen. These include agriculture, hydrology, weather, and human health, to name just a few. But first it is important to understand what soil moisture is. Soil moisture is the available water contained within the matrix of … Continue reading How does soil moisture impact our lives?
