Soil sulfur availability due to mineralization: Soil amended with biogas residues

January 2014

Sulfur, an essential element for plant growth, has received lesser attention than it deserves. Current inputs of sulfur to agricultural soils from atmospheric deposition have reduced to less than the amount sulfur required by most crops. In such soils the release of sulfur from organic matter is vital for the supply of sulfur. A pot experiment without plant (incubation study) in a green house was conducted at the...
