Effects of Wood Ash Fertilization on Forest Soil Chemical Properties
The effects of wood ash fertilization on soil chemical properties were studied in three young Scots pine (Pinus sylvestris L.) plantations and a Norway spruce (Picea abies (L.) Karst.) plantation with different site fertility in southern Finland. The dose of 3 t ha–1 of loose wood ash was applied to 4 replicate plots (25 × 25 m) at each experiment. Humus layer and mineral soil samples were take...
متن کاملRunoff Characteristics in Forest Plots before and after Wood Ash Fertilization
Spreading wood ash on forest and agricultural lands has been used for years to correct pH in acid soils and as a source of plant nutrients. However, it is necessary to enhance the knowledge of potential hazards derived from such a practise. Surface runoff pollution is one of these possible hazards. In this work we studied the quality of runoff water collected in two sloped forest plots before a...
متن کاملCharacteristics of Wood ASH/OPC Concrete
The study presents the behaviour of wood ash / OPC concrete. Chemical analysis of wood ash, bulk density, sieve analysis and specific gravity of wood ash and aggregates, consistency, setting time and slump test of the fresh paste were conducted to determine the suitability of the materials for concrete making. Mix ratio of 1:2:4 and percentage replacement level of 0, 10, 20, 30 and 40 percents ...
متن کاملUse of wood ash and anaerobic sludge for grassland fertilization: Effects on plants and microbes
Increasing the share of renewable energies is among the prime policies of the European Union. Among the options are the incineration of wood in combined heat and power plants as well as the anaerobic digestion of organic materials to obtain biogas. Both processes leave behind residual matter – wood ash and anaerobic sludge. These residual materials contain chemical elements with considerable fe...
