Degradation of soils over the past 40 years has been due to the depletion of organic matter content, resulting in decreased crop yields. To produce two tonnes of maize per acre, an uptake of nitrogen ...

Corn and soybean yields have increased dramatically since 2000, according to a new study from South Dakota State University's ...

Enzymes digest the organic matter outside their cells ... If conditions are not favourable for the process of decomposition, dead organisms decay slowly or not at all. These organisms build ...

When air can’t reach organic matter, it starts to decompose through anaerobic decomposition, which is decomposition by organisms that don’t need oxygen to survive. Anaerobic decomposition ...

"Tillage intensity reductions slows soil organic matter decomposition, which increases the ability of the soil to retain water, leading to improved yields. Higher yields lead to soil organic ...

CORVALLIS – Adding organic matter is the best way to improve nearly all kinds of soils. If you’re unsure if your soil needs amendments, take note if it dries and cracks in summer, drains ...
