The role of living plant roots and cattle manure as a soil amendment in the alleviation of compacted coal mine soils
… activities change the physical nature of the soil which results in soil compaction. In mine soils, compaction is of great importance in plant growth and the environment because its high levels may adversely result in the degradation of soil structure, reduced nutrient distribution and reduced …
