An investigation of the effect of biochar application rates on CO2 emissions in soils under upland rice production in southern Guinea Savannah of Nigeria

open access: yesHeliyon, 2020
Biochar is a chemically recalcitrant carbon-rich solid material used in soil for its potential to improve soil quality and sequester carbon. While the rate of application has implications for soil carbon dioxide (CO2) emission and the overall benefits of

Game Changer in Soil Science. Functional role of clay minerals in soil [PDF]

open access: yesJournal of Plant Nutrition and Soil Science, 2018
AbstractDefining soil clay minerals as all inorganic particles < 2 µm would enhance their predictive power for soil functions. The future task is to unravel the prominent functional role of clay associations in the “ultimate particles” in soils–microaggregates.

Global climate change and tree nutrition: effects of elevated CO2 and temperature [PDF]

open access: yes, 2010
Although tree nutrition has not been the primary focus of large climate change experiments on trees, we are beginning to understand its links to elevated atmospheric CO2 and temperature changes. This review focuses on the major nutrients, namely N and P,

Comparison of indices for the prediction of nitrogen mineralization after destruction of managed grassland [PDF]

open access: yes, 2010
Intensively managed grasslands are occasionally chemically killed with herbicide and ploughed in order to grow an arable crop. After this management, large N mineralization rates with large losses to the environment are commonly observed.
