“…The relationships between the soil structure parameters and texture as well as SOM were evaluated as shown in Table 3. The soil structure is affected by many factors (Amézketa, 1999;Bronick and Lal, 2005;Wiesmeier et al, 2012;Czachor et al, 2015;Šimanský and Jonczak, 2016;Šimanský et al, 2019), what has been confirmed with our findings. However, obtained results clearly show that not every factor influencing soil structure was influenced the same way.…”

“…Aggregate stability depends on the content of base minerals and the type of clay minerals, soil organic matter, electrolyte concentration, texture, soil management practices etc. (Bronick and Lal, 2005;Šimanský et al, 2019). The soil structure have been studied previously in different soil types, climate conditions and under varying soil management practices (Šimanský et al, 2014;Bartlová et al 2015;Šimanský and Jonczak, 2016;Šimanský et al, 2019).…”

Licensed under a Creative Commons Attribution 4.0 International License The type of slope and its interaction with soil management practices are one of the most important factors affecting soil structure along the slope gradient. In this study, the effects of fallow in greening and intensive soil cultivation both located on slopes on changes soil properties especially soil structure were evaluated. Soil samples were collected from two fields (neighbouring fields) between Trakovice and Bučany villages (Slovakia). The terrain of both fields was sloping with a WN-ES orientation and a slope of <8°. Field 1 is used as arable land with intensive cultivation of crops (IC). In field 2, the fallow in greening (G) was established in 2012 and in 2018 soil samples were taken in five zones of both slopes as follows: on the summit slope, shoulder, back slope, toe slope and flat. Results showed that structure coefficient (K) was strongly affected by both land use (p = 0.0000) and slope position (p = 0.0206) as well as by the interaction of land use and slope position (p = 0.0010). The statistically significantly highest structure coefficient of water-stable aggregates (Kwsa) and opposite the lowest macro-aggregate destruction (PAD) were found for G compared to IC. In G, the index of crusting (Ic) increased by 9% compared to IC. The critical level of soil organic matter (S t) was strongly affected by both land use (p = 0.0114) and slope position (p = 0.0000). The values of S t were statistically significantly influenced by interaction of land use and slope position. When land use and slope position were assessed together, positive significant correlations were observed between silt and carbonate contents and Ic. On the other hand, the S t values were strong effected soil organic matter (SOM) quantity and quality. In IC, positive correlations between C L (r = 0.773, P <0.01) and K were observed. Ic correlated with silt (r = 0.650, P <0.05), carbonates (r = 0.704, P <0.05) and lower humus stability. A higher silt and carbonate contents as well as higher content of SOM and better humus quality resulted in higher S t values. In G, the K values positive correlated with silt and carbonate contents. Higher humus quality and stability improved soil structure evaluated on the base of Kwsa.

“…Sandy soils occur in different environments but their use in agriculture is limited because of their low productivity. Typical features of sandy soils are high permeability, low water and nutrient storage capacity and low contents of SOM (Šimanský et al, 2019;Šimanský and Jonczak, 2020). If farmers wish to develop effective and ecological farming on any soil, they have to know the soil characteristics, the reasons of the soil low fertility and the pathways to eliminate the problems.…”

The effort to achieve the sustainable farming system in arable soil led to the intensive search for a new solution but an inspiration can also be found in the application of traditional methods of soil fertility improvement as it is shown in numerous examples in history. Recently many scientific teams have focused their attention on the evaluation of biochar effects on soil properties and crop yields. Since there are a lot of knowledge gaps, especially in explanations how biochar can affect soil organic matter (SOM) and humus substances, we aimed this study at the solution of these questions. Therefore, the objective of the experiment was to evaluate the impact of two biochar substrates (B1 – biochar blended with sheep manure, and B2 – biochar blended with sheep manure and the residue from the biogas station) at two rates (10 and 20 t ha-1) applied alone or in combination with mineral fertilizers (Urea was applied in 2018, at rate 100 kg ha-1, and Urea at rate 100 kg ha-1 + AMOFOS NP 12-52 at 100 kg ha-1 were applied in 2019) on the quantity and quality of SOM and humus of sandy soil (Arenosol, Dolná Streda, Slovakia). The results showed that application of the biochar substrates together with mineral fertilizers (MF) had more pronounced effect on the organic matter mineralization in the sandy soil which resulted in low accumulation of soil organic carbon (Corg) and labile carbon compared to biochar substrates treatments without MF. The share of humic substances in Corg significantly decreased by 16, 50, 16 and 24% in B1 at 10 t ha-1, B1 at 20 t ha-1, B2 at 10 t ha-1 and B2 at 20 t ha-1 treatments, respectively, compared to the control. A similar tendency was observed for biochar substrates treatments + MF, compared to MF control. The carbon content of humic substances (CHS) was equal to 4.40 – 5.80 g kg-1 and the biochar substrates had statistically significant influence on CHS content. On average, there was a smaller decrease of CHS in B1 at rate 10 t ha-1 than at rate 20 t ha-1 and no effect of B2 compared to control. The carbon content of fulvic acid (CFA) was 9% higher in B1 at 10 t ha-1, and 20 t ha-1, 47% higher in B2 at 10 t ha-1 and 17% higher in B2 at 20 t ha-1 compared to control. As a result of biochar substrates + MF application, the reduction in CFA was observed. The results showed a decrease of CHA : CFA ratio with association to biochar substrates alone application compared to control on one hand, and a wider of CHA : CFA ratio in biochar substrates + MF treatments in comparison to MF control on the other hand. Humus stability was increased in biochar substrates alone treatments compared to control, on the other hand, compared to MF control, the application of biochar substrates + MF resulted in a lower humus stability.

“…This very important soil feature is associated with the soil colloidal complex that includes mineral and organic components. Thanks to this soil property, plant root system is supported by a supply of biogenic elements from the soil; meaning that farmers do not need to add these elements on a daily basis (Foth 1990;Lorandi 2012;Šimanský & Polláková 2014;Šimanský et al 2018). Soil organic matter, especially the decomposed and humified variety, together with soil clay content significantly influence soil sorption capacity (Foth 1990, Manjaiah et al 2019.…”

In this paper, the results of an investigation of the effects of particle-size distribution, soil organic matter content and its parameters on soil sorption capacity are presented and their mutual relationships in sandy soils under long-term fertilisation experiments are determined. Soil samples were taken at the experimental station of Warsaw University of Life Sciences located in Skierniewice, (Poland) in spring 2017. The study included 94- and 41-year-old experiments with mineral fertilisation (no fertilisation, NPK, CaNPK) and 25-year-old experiment with mineral fertilisation + farmyard manure (FYM) in 4-year cycle: FYM, FYM+NPK and FYM+CaNPK. The results show that in the 94-year-old experiment in NPK and CaNPK treatments, hydrolytic acidity (Ha) decreased in comparison with the control by 30% and 88%, respectively, while in 25- and 41-year-old experiments only the application of NPK significantly increased Ha values. The sum of basic cations increased by a factor of 10 at the most in the CaNPK treatment in the 94-year-old experiment. The same effect was also observed in the 25-year-old experiment. On the one hand, the sorption complex gradually became fully saturated as a result of fertilisation in the 94-year-old experiment. On the other hand, in the 25- and 41-year-old experiments, base saturation was substantially reduced. A higher humus stability was an important agent for improving soil sorption capacity in 41- and 94-year old experiments.
