Farmers in the area are trying a new way to cut costs and keep groundwater clean. A local extension teacher started the “Nitrogen Challenge” after farmers asked if they were still adding too much fertilizer to their fields. The goal is simple: give each crop exactly the amount of nitrogen it n
Researchers examined how adding organic material changes the tiny life in two different soils. The study focused on microbes that help break down nutrients and keep the climate stable. Scientists wanted to know if these tiny organisms would react in the same way when the soils receive the same organ
This study looked at how rocks under farmland can put harmful metals into soil and rice. Three common rock types were studied: phosphorite, black shale, and basalt. The researchers measured the amounts of lead, arsenic, mercury, cadmium, zinc, chromium, nickel and copper in the soil and in rice grai
In a German grassland study, researchers looked at how the number of plant species affects tiny life in the soil. They took samples from plots that had between one and sixteen different plants, ranging from grasses to legumes to herbs. By sequencing the DNA of bacteria and fungi living there, they c
In the chilly northern farmlands, soil cracks are a big problem. They appear when the ground freezes and thaws. These cracks let water and soil wash away. This is called erosion. Scientists wanted to see if adding special substances could help. They used a lab to mimic the cold weather and rain. Th
Soil is not just dirt. It's a big deal for farmers. When it washes away, it takes more than just the ground. It takes money and options. In Italy, farms losing too much soil are feeling the pinch. They make less profit. Their return on assets drops by 1. 20%. Their return on equity falls by 2. 10%.
Cadmium, a toxic metal, is sneaking into rice fields in southern China. It's a big deal because it's making its way into the food chain. Scientists have been trying to figure out where it's coming from and how to stop it. They created a detailed model to track cadmium's journey. It shows that the m
In Brazil's dry, thirsty lands, the ground is struggling. Plants are sparse. The soil is tired. But there's a glimmer of hope. People are trying to fix it. And guess what? Tiny bacteria are feeling the difference. These tiny life forms are everywhere in the soil. Some are common. Others are rare. T
Wetlands are like nature's kidneys, cleaning up the environment. But they're under attack from harmful metals and metalloids (HMs) from human activities. These nasty substances can be super toxic and move around easily, depending on their form. Microbes in the soil can change these forms through pro
In the rocky landscapes of Karst regions, a battle is quietly unfolding between oilseed rape plants and a silent enemy: cadmium. This heavy metal sneaks into the soil and can cause big problems for plants and the people who eat them. But oilseed rape has some clever tricks to deal with this issue.
