Impact of Soil Fertilized with Biomass Ash on Depth-Related Variability of Culturable Bacterial Diversity and Selected Physicochemical Parameters in Spring Barley Cultivation
by Miłosz Pastuszczak, Jadwiga Stanek-Tarkowska and Miroslava Kačániová
Int. J. Environ. Res. Public Health 2022, 19(21), 13721; https://doi.org/10.3390/ijerph192113721 - 22 Oct 2022

This study investigated the effect of different doses of fertilization with biomass combustion ash (Salix viminalis L. willow) on changes in the biological, chemical, and physical properties of soil. The experiment was carried out on podzolic and chernozem soils in a one-way field experiment (fertilization dose: control (without fertilization), NPK (nitrogen (N), phosphorus (P) and potassium (K)), 100, 200, 300, 400, 500 kg K2O ha−1). The biomass ash was characterized by a pH value of 12.83 ± 0.68 and a high content of macronutrients. The samples were collected from 0–5, 10–15, and 20–25 cm soil layers under the cultivation of spring barley (Hordeum vulgare L) cv. Planet in April and August 2021. Mass spectrometry (MALDI-TOF MS) was used for microbiological analyses, which revealed the presence of 53 culturable species from 11 genera: Bacillus, Pseudomonas, Paenibacillus, Lysinibacillus, Pseudarthrobacter, Arthrobacter, Staphylococcus, Paenarthrobacter, Micrococcus, Rhodococcus, and Flavobacterium. The podzolic and chernozem soils exhibited the presence of 28 and 44 culturable species, respectively. The study showed an increase in the number of microorganisms in the top layer of the soil profile. However, the number of bacteria decreased at the depths of 10–15 cm and 20–25 cm. With depth, the bulk density (BD) and moisture increased. Full article

The aim of the research was to investigate whether different doses of ash from biomass combustion (Salix viminalis L. willow) have an impact on the number and community of soil bacteria. The experiment was carried out on podzolic and chernozem soils in a one-way field experiment (control, NPK, 100, 200, 300, 400, 500 kg K2Oha−1). The ash from the biomass was characterized by pH 12.83 ± 0.68 and high content of macronutrients. Samples were taken from the 0–5 cm layer of soil under the cultivation of winter oilseed rape (Brassica napus L. var. Napus) in April and September 2021. The plate count method with PCA solid medium was used to determine the number of microorganisms, and mass spectrometry (MALDI-TOF MS) was used to analyze the microbiological community. The research showed an increase in the number of microorganisms after the use of the biomass ash fertilizer in the variants with ash doses from 200 to 500 kg K2Oha−1. The highest amount of soil bacteria in both tested soils was determined in these variants. In total, 44 bacterial species of 5 genera were identified in all variants: Bacillus, Paenarthrobacter, Pseudarthrobacter, Pseudomonas, and Rhodococcus. An important factor in the growth of the number of bacteria, in addition to the dose of biomass ash, was soil moisture, which in September was significantly higher than in April 2021 in both soils.

The purpose of this study was to evaluate the effect of ash from combustion of plant biomass of energy willow and Pennsylvania fanpetals on yields of willow grown as an energy crop and on soil properties. A three-year pot experiment was carried out on substrates with a loamy sand texture. Ash application rates were based on the potassium fertilisation demand. An incubation experiment was carried out to determine the effect of biomass-based ash on soil properties. Three soils with textural categories were incubated for 3 months with the ashes, the doses of which were determined on the basis of the hydrolytic acidity of soils (¼; ½ and 1.0 Hh). It was found that ashes generated from burning willow or Pennsylvania fanpetals can be applied instead of phosphorus, potassium and magnesium fertilisers in the cultivation of energy willow. The plant uptake of P, K and Mg from the ashes did not diverge from their absorption by plants when supplied with mineral salts. The application of these alkaline ashes will increase the soil content of phytoavailable forms of phosphorus, potassium and magnesium. The examined ashes enriched the soil with micronutrients.
