The Influence of Biomass Ash on the Migration of Heavy Metals in the Flooded Soil Profile - Model Experiment

Abstract

Soils that have been exposed to flood waters can be heavily polluted by inorganic and organic compounds. They are mainly compounds which appear in dissolved or suspended form flowing together with heavily laden floodwater, as well as compounds created as a result of reactions in the soil profile, mostly due to anaerobic transformation of organic matter. Heavy metals brought with flood waters are absorbed by the soil and also washed out from flood sediments by precipitation when the flood recedes. This paper presents the results of research on the effects of fertilization with ash from incineration or pyrolysis of biomass on the migration process of heavy metals (Zn, Cu, Cr, Ni, Pb, Cd, Mn) in the arable layer of soil. It has been shown that the metals in the flood sediment migrate actively in the soil profile what leads to the enrichment of the soils, also in the case of the soil fertilization with biomass ash.

Impact of Selected Properties of Raw Material on Quality Features of Granular Fertilizers Obtained from Digestates and ASH Mixtures

Abstract

The paper presents the results of research, the objective of which was to determine the impact of particle size distribution and density of digestates and ash on density and tensile strength of granular fertilizer obtained from mixtures of these substrates. Particle size distribution, absolute density, envelope density and porosity of substrates were determined. Granular fertilizers were made of clean substrates and their mixtures. Envelope density of the obtained granulates was within 0.81 - 1.88 g⋅cm-3. The determined compaction degree was within 3.65 - 10.12. While, the compaction index IS of granulates made of mixtures was within 0.5 - 0.55 and was lower in comparison to IS of granulates from digestates (0.6) and ash (0.76).

The Composition and Use Value of Tree Biomass Ash

Abstract

Wood-based ash landfilling is increasing issue not only in Latvia but in the whole world as more biomass is used for energy production. Utilization of wood burning waste as fertilizer is already used worldwide, but there is lack of information about chemical composition of wood ash obtained from Latvia plants, so the aim of this study was to determine chemical composition and analyse possible utilization options of wood-based ash from Latvia plants. Therefore wood ash samples from 53 companies were collected, sieved and chemical composition of samples was determined. It was concluded that within higher capacity of furnace more coarse fraction of wood ash was observed which is less valuable as fertilizer. Wood ash is good liming material consisting alkali compounds and other biogenic elements but also heavy metals, which are pollutants and could cause environmental problems.

Acute toxicity of experimental fertilizers made of blood meal, spent coffee ground and biomass ash

Abstract

The study presents the results of research on the acute toxicity of a fertilizer formulas made of spent coffee ground (SCG) with addition of ash from low-temperature combustion of biomass or ash with an admixture of magnesium sulphate and blood meal. The experimental fertilizer formulas included also rape oil used as a plasticizer for controlling the nutrients release from the fertiliser. Mustard (Sinapis alba L.), oats (Avena sativa sp. L.), cucumber (Cucumis sativus L.) and cress (Lepidium sativum L.) were used as test plants species in the experiment. The toxicity tests were performed using a standard procedure of 72 h with the use of Phytotoxkit microbiotest and fertilizer application of 2.5; 5 and 10% (v/v). The obtained results indicated an increase of acute toxicity for all tested plant species, proportionally to the applied doses of the fertilizer. During the 72 h period, the strongest inhibition of seedling growth was recorded in samples consisting of 10% of the tested fertilizers, particularly when they showed considerable level of salinity or low pH values. From the tested plant species, cress (Lepidium sativum L.) turned out to be the most sensitive to the applied fertilizers, the least was cucumber (Cucumis sativus L.) for which only a small inhibition of root system growth was observed. The inhibited growth of roots could be attributed to a reduced oxygen access and excessive salinity of the substratum caused by the applied additives.

Effects of Limestone, Ash from Biomass and Compost Use on Chemical Properties of Soil

Abstract

The aim of this research was to assess the use of biomass ash for fertilisation of mineral soil. The study involves the analysis of the effects of biomass ash applied to soil on the changes of pH and the content of the available forms of phosphorus, potassium and magnesium as well as on total content of zinc, copper, manganese, nickel, cadmium and lead. The field experiment was conducted in 2013 in Duninowo near Ustka. In experiment grown two plants spring: Spring barley - var. Sebastian, and wheat - var. Bombona. The use of ash from biomass and Biotop compost as fertilisers did not result in any significant changes of soilpH. The use of ash from biomass and Biotop compost caused a significant increase in the contents of available phosphorus, potassium and magnesium in soil. The threshold values of the analysed trace elements in soil, as specified by the Regulation of the Minister of Environment, were not exceeded in any of the fertilising variants in the experiment.
