The CENTURY Soil Organic Matter Model

The CENTURY version 5 agroecosystem model is the latest version of the soil organic model developed by Parton et al. (1987). This model simulates C, N, P, and S dynamics through an annual cycle over time scales of centuries and millennia. The producer submodel may be...

Soil organic carbon balance using Century model

Abstract Mathematical modelling has widely been used during the last 20 years to estimate and predict soil organic carbon (SOC) balance and nutrients dynamic on the landscape scale. The model simulations are applied and developed to assess the long-term effects of...

Only 60 years of farming left if soil degradation continues

Generating three centimeters of top soil takes 1,000 years, and if current rates of degradation continue all of the world’s top soil could be gone within 60 years, a senior UN official said on Friday. About a third of the world’s soil has already been...

Overview of Greenhouse Gases

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2013, CO2 accounted for about 82% of all U.S. greenhouse gas emissions from human activities. Carbon dioxide is naturally present in the atmosphere as part of the Earth’s...
