A thin layer found in the top few centimeters of soil plays a big role in its ecology. Biocrust is built, maintained and ...

Landslides are one striking example of erosion. When the bonds that hold particles of dirt and rock together are overwhelmed by a force — often in the form of water — sufficient to pull the ...

Soil is composed of solid particles and pore spaces. Pore spaces make up approximately 50% of soil by volume. They act as conduits for air and water movement through the soil.

Contour planting helps reduce soil erosion and water runoff.When crops are planted down a slope, water flows quickly through the rows, especially during heavy rain.Instead of percolating into the ...

Plus, in dry earth the gaps between the soil particles are full of air, which has no way of escaping—blocking the water from moving down into the earth. Soil particles themselves can also become ...

We collected over 2,000 invertebrates and soil samples from 51 sites in Sussex, England. The sites covered farmland, grassland and suburban areas. To trace how plastic might move through the food ...
