Soil is a mixture of tiny particles of rock, dead plants and animals, air and water. Different soils have different properties depending on their composition. Sandy soil is pale coloured and has ...

A very important part of the success of this project is an understanding of the soil food web, in other words, how organisms ...

Soils tend to become acidic as a result of: (1) rainwater leaching away basic ions (calcium, magnesium, potassium and sodium); (2) carbon dioxide from decomposing organic matter and root respiration ...

Soil carbon storage is a vital ecosystem service, resulting from interactions of ecological processes. Human activities affecting these processes can lead to carbon loss or improved storage.

These are taken up by the roots and then used by the plant to form flowers and leaves. The relative proportions of all these, along with pH, determine soil type. The pH of a soil refers to its ...

As you work the soil, pay attention to how it feels in your hands. How well does the soil form a ball? Does the ball hold ...

From formal lab tests to DIY baking soda and vinegar, here's how to choose which method is best for your garden, lawn and ...

Aquic - poorly drained soils that are saturated when the soil temperature (at 50 cm) is above biological zero (>5°C). These soils typically display evidence of prolonged saturation in the form of ...

A new study of ancient rocks on Mars reveals how the planet was likely uninhabitable — at least on the surface — after much ...

Soil Science involves course work and thesis research in soil chemistry, soil fertility and management, soil physics, soil microbiology and biochemistry, environmental microbiology, soil and water ...

In this form, the carbon can remain in soils for thousands of years, increasing the soil fertility and acting as a carbon sink. This sequestration of the carbon helps to meet targets to reduce ...
