Agriculture accounts for more than a third of water use in the United States. In drier parts of the country, like the southwestern U.S., that fraction can be much higher. For example, more than 75% of New Mexico’s water use is for agriculture. 

A favorite healthy snack, almonds are a staple on grocery store shelves worldwide. More than 80% of these almonds are grown in California. As permanent crops, almond trees have unique needs and challenges for farmers.

Chocolate is almost universally adored. But few know the complicated process of how cacao beans become chocolate. Did you know cacao tree farming is done mostly by small-scale low-income farmers in Latin America, particularly in countries like Ecuador?

Earth is getting hotter. Huge amounts of greenhouse gases are warming the planet and altering the climate. Heat waves are harsher. Droughts are longer. And some diseases and pests are stronger than ever.

After an oil spill or leak, it’s important to act fast. If the oil has gotten into soil, scientists need to rapidly assess how much oil there is and how far it spread. It’s a process that has always been costly and time-consuming.

Many living creatures live in soil. Though their sizes range from microscopic soil microbes to larger animals like gopher turtles, they all call soil their “home.” Included in these ground-dwelling species are bees – vital in the pollination cycle of about 90% of plant life.

For most of us, our closest encounter with the element fluorine is likely to be our toothpaste or a municipal water supply with added fluoride.

But excess fluorine can be a problem. For example, high levels of fluorine in the soil can hurt plants. Fluorine in soils may also affect microbes and other organisms higher along the food chain.

Chicken is the most consumed protein in the United States. According to the National Chicken Council, the U.S. produced more than 9.2 billion broiler chickens in 2019. US consumers spent more than 95 billion dollars on chicken products.

What goes down the drains can be used to make things grow.

Sewage sludge – carefully treated to make it safe – is used often in agriculture. Now, researchers are testing these materials, called biosolids, for use in urban settings.

Soils in deserts are very different from those found anywhere else. Extreme temperatures, little water and limited plant matter make an unusual environment. With little dead plant material to decompose and create a rich layer of organic matter, desert soils are unique.
