Improving coarse-textured mineral soils with pulp and paper mill sludges: Functional considerations at laboratory scale Geoderma (IF 6.1) Pub Date : 2023-07-19
Building up the organic matter content of coarse-textured soils with organic amendments seeks to ameliorate the productivity of these soils, which is limited by plant available water and nutrient supply. Wood fibre-based sludges from the pulp and paper industry have potential for soil conditioning. In this study, the effects of three different pulp and paper mill sludges at application rates of 10
