What are the best management practices of the Everglades Agricultural Area?

The Everglades of Florida are not just swamp-filled alligator territory! Part of the Everglades is managed as a highly productive agricultural area. Called the Everglades Agricultural Area, it is located south of Lake Okeechobee. The land mass area is about one fourth the size of the original everglades. Soils in the Everglades Agricultural Area are … Continue reading What are the best management practices of the Everglades Agricultural Area?

What is soil made of?

Soils can look like they are a homogeneous material. But in reality, soil contains solid particles of different sizes and different types. Some of the particles are minerals, and others are organic matter. There are spaces between the particles called pores. These pores may be filled with air or water. Soil is a mixture of … Continue reading What is soil made of?

Are there soil microbes under my fingernails?

If you’ve been gardening without gloves lately, then the answer is probably “yes.” But that is, for the most part, a good thing – besides having to clean your hands! In garden soil there are millions to billions of microorganisms, or microbes. They could be bacteria, fungi, viruses, and archaea. Baseline estimates suggest that there … Continue reading Are there soil microbes under my fingernails?

Can industrial hemp be intercropped in pine plantations?

Land covers about 29% of the Earth’s surface and is an essential natural resource for the survivability and prosperity of humanity. As the human population continues to expand, land and other natural resources will begin to experience depletion. I currently work with industrial hemp, and its recent legalization opened opportunities for hemp-based research. Knowing how … Continue reading Can industrial hemp be intercropped in pine plantations?

What do ants and soils do for each other?

Have you ever wondered how important ants are for agriculture and soils? They do not get much credit for their contribution towards our planet Earth. Moreover, many people dislike them. Don’t we? We certainly don’t appreciate them in our homes – or on our picnic tables! Imagine a situation where you are in a corn … Continue reading What do ants and soils do for each other?

Can the parts of plants we can see help predict the parts of them we can’t?

There’s a lot we can tell about plants by looking at them. We can see their leaves, stems and overall structure. If it’s a flowering plant, we can see them, too. But we can’t see what the roots look like under the ground, like root depth or structure. Our research team decided to study if … Continue reading Can the parts of plants we can see help predict the parts of them we can’t?

How can farmers grow crops in more coarse soils?

Particles of sandy soils generally have a mean diameter between 0.05mm and 2mm. They are the largest of soil particle types – the smaller particles are called silt and clay. A soil that is good for farming consists of a mixture of these particles, allowing for healthy crops. Loam is a particularly good type of … Continue reading How can farmers grow crops in more coarse soils?

How are oysters farmed – and what’s the effect on subaqueous soils?

These days, oyster aquaculture is stirring up the conventional definition of agriculture. But exactly how does one grow a crop of oysters? More specifically, how are soils involved in this underwater process? Let’s start by outlining a few key concepts. “Aquaculture” is the farming of aquatic plants and/or animals for food. Oyster aquaculture has a … Continue reading How are oysters farmed – and what’s the effect on subaqueous soils?

How did soil salinity affect ancient civilizations?

Irrigation is a common farming practice, several thousand years old. It is an effort to add water to crops when rainfall is not enough to grow those crops. A North American group called the Hohokam lived 600-1600 years ago in the Lower Salt River valley in Arizona. They are well-known for their irrigation engineering. The … Continue reading How did soil salinity affect ancient civilizations?

How are soil microbes affected by fertilizer in soils?

There isn’t a simple answer to this complex question – but my research hopes to shed some light on this important subject. The key to answering this question starts with understanding that all soils, microbes, and fertilizers are unique. Different farms – or even areas within a farm – may have different situations. Interactions between … Continue reading How are soil microbes affected by fertilizer in soils?
