Soil organic matter
Delta, Fraser Valley, decline in soil organic matter
Vital to soil health, organic matter is declining in the delta and throughout the Fraser Valley Soil organic matter (SOM) is the fraction of soil composed of decomposed plant and animal tissues to varying degrees, and is essential…
FTIR helps understand soil organic matter Labmate Online
Soil chemistry aims to characterize the content of soils to understand their ability to promote plant growth and act as carriers of environmental contaminants. There has been a shift towards the latter in recent years.…
A new way to analyze soil organic matter will help predict climate change
WACO, TX- A new way to analyze the chemical makeup of soil organic matter will help scientists predict how soils store carbon — and how soil carbon may affect climate in the future, says a Baylor University researcher .A study by scientists…

Steven Hall is dedicated to exploring how farmers can get the most out of their soil.Hall, an assistant professor in the Department of Ecology, Evolution, and Organismal Biology at Iowa State University, runs a biogeochemistry lab where…
The link between soil organic matter and soil water
By Anna Cates, State Soil Health SpecialistOne of the benefits of increasing soil organic matter is storing more water in your soil. Why does this happen? Because the organic matter in the soil creates pores of different sizes. However,…
Understanding Soil Organic Matter – Grainews
The word “organic”, like “environmental”, has become confusing over the last 20 or 30 years. Organic food for example? All the food we eat is organic (except salt or other minerals). All agricultural activities are environmental, but…
The Yield Benefits of Soil Organic Matter Have a Limit
Researchers find that higher yields that come from increased organic matter in the soil will eventually decline For years, most farmers have understood that increasing the volume of organic matter in the soil will provide nutrients to…

Soil organic matter is an indicator of soil health and performs many important functions. The higher the…
Can soil organic matter increase at an annual rate of 1%? – Sterling Journal-Lawyer
Soil health is a key driver of agricultural productivity and environmental resilience. In the early 1990s, soil health was defined as "the ability of soil to function as a vital life system, within ecosystem and land use limits, to support…
Can I increase soil organic matter by 1% this year?
By Sjoerd Willem DuikerThis fall, I participated in workshops where a farmer claimed that the organic matter in his soil was increasing by 1% per year. Is this a realistic goal to aim for?The source of soil organic matter is photosynthesis…
