When farmers talk about their soil test results, the conversation often starts and ends with soil pH. While that one number is important to determining whether lime is needed, that insight is just a ...

Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale ...

It's an easy way to check the acidity of your soil. Boiled red cabbage water can be used as a simple DIY soil pH test by mixing it with soil and observing the color change after a few hours. The ...

Though a founding concept of ecology suggests that the physical environment determines where organisms can survive, modern scientists have suspected there is more to the story of how microbial ...

Using isotope tracing to track ammonium and nitrate uptake, scientists found that wheat dominates nitrogen capture in calcareous (alkaline) soils, while microbes compete more effectively in acid soils ...

For some time now, scientists have known that climate influences soil chemistry -- and, in particular, soil pH, a measure of acidity or alkalinity. In dry climates, soil is alkaline; in wet climates, ...
