“…Castaldi et al, 2011;Cornelissen et al, 2018). Since the biochar is alkaline, it might increase of soil pH, but this effect could be softened with adding The biochar application can be beneficial for soil pH enhancement (e. g. Chintala et al, 2013;Obia et al, 2015;Horák et al, 2017;Teutscherova et al, 2017;Šimanský et al, 2018) as confirmed by our data. As shown in Fig.…”

In this paper we investigate the effects of biochar alone and its reapplication and combination with N-fertilizer (1) on the soil pH, and (2) sorption parameters. The soil samples were taken during growing period in 2018 from plots with different biochar (first application in 2014 – A, reapplication in 2018 – B) at application rates: 0 t.ha−1 (B0 control), 10 t.ha−1 (B10) and 20 t.ha−1 (B20) and different nitrogen fertilization: N0 (no nitrogen) and N40 (40 kg.ha−1). Our results showed that the first application of biochar at the rate of 20 t.ha−1 (B20A) without N-fertilizer significantly increased the values of soil pH in H2O, soil pH in KCl, the sum of base cations (SBC) and cation exchange capacity (CEC) compared to control (B0). Similar effects were observed also after reapplication of biochar (B10B). All investigated parameters in fertilized control treatment (B0N40) were worst and the first application, as well as the reapplication of biochar with N, caused significant increase of soil pH in H2O, soil pH in KCl, SBC, CEC, BS and decrease of hydrolytic acidity.

“…Significantly lower N 2 O emission peaks were recorded from soils with biochar application compared to those without biochar, resulting in lower cumulative N 2 O emissions from biochar-amended soils during the first year of the experiment. Total cumulative N 2 O emissions (taken between March and November 2014) from the soil with biochar with or without N-fertilizer were 19-32% lower than those from the soil without biochar [42]. The results confirm that biochar application has the potential to reduce N 2 O emissions from the soil.…”

“…Factorial experiments are therefore one of the most effective ways of elucidating these relationships and interpreting in detail the impact of biochar on the particular crop. Early results from this experiment observed in 2014 could be indicative of a rapid change in soil properties, the highest barley yields were obtained in plots with pH of about 5.65 [42]. During the growing season a conventional digital camera was used as a non-destructive non-contact method of crop emergence monitoring and crop growth development [51].…”

One of the reasons for the lack of progress in increasing food production to feed a growing human population is continuous degradation of soil resources in the 21 st century. The production function of arable soils thus clearly plays a critical role in the future of humankind [1]. The concept of soil quality, an important but elusive concept still waiting for a clear definition, is a useful indicator of the capacity of the soil to support crop growth and thus food production. Soil quality has received substantial attention in scientific literature and is often used as a diagnostic tool for monitoring and to inform management of agricultural soils. Agricultural land in 2016 covered about 4.9 billion ha worldwide, corresponding to 37.6% of the total world land area

“…This study aimed to determine and compare the long-term effect of the biochar-based organic amendments on selected soil properties (MBC, DHA and soil microbial community abundance) on the agricultural land of the temperate climate zone of Central Europe. Only a few studies have been done so far on the agricultural area of temperate soils [37][38][39]. Prior studies suggested that manure addition to biochar as a soil amendment might have a synergistic or antagonistic effect.…”

Long-Term Effects of Biochar-Based Organic Amendments on Soil Microbial Parameters

Biochar application to the soil has been recommended as a carbon (C) management approach to sequester C and improve soil quality. Three-year experiments were conducted to investigate the interactive effects of three types of amendments on microbial biomass carbon, soil dehydrogenase activity and soil microbial community abundance in luvisols of arable land in the Czech Republic. Four different treatments were studied, which were, only NPK as a control, NPK + cattle manure, NPK + biochar and NPK + combination of manure with biochar. The results demonstrate that all amendments were effective in increasing the fungal and bacterial biomass, as is evident from the increased values of bacterial and fungal phospholipid fatty acid analysis. The ammonia-oxidizing bacteria population increases with the application of biochar, and it reaches its maximum value when biochar is applied in combination with manure. The overall results suggest that co-application of biochar with manure changes soil properties in favor of increased microbial biomass. It was confirmed that the application of biochar might increase or decrease soil activity, but its addition, along with manure, always promotes microbial abundance and their activity. The obtained results can be used in the planning and execution of the biochar-based soil amendments.
