“…Humic acids are rich in organic matter, which can significantly improve the soil structure and increase the content of SOM. In various studies, these substances have been used to affect the soil hydrophysical characteristics [26,27]. For instance, Xu et al [28] and Ma et al [29] discovered that the application of humic acids increased the soil's water retention capacity by enhancing macroaggregation.…”

In recent years, products containing humic acids have been increasingly used in agriculture to improve soil parameters. Quantifying their impact on soil quality is, therefore, of key importance. This study seeks to evaluate the impact of the commercial humic acid product (HA) on the hydrophysical parameters of sandy and clayey soils sampled from different sites in Slovakia. Specifically, the study hypothesizes that humic amendment will enhance particle density (ρs), dry bulk density (ρd), porosity (Φ), saturated hydraulic conductivity (Ks), soil water repellency (SWR), and water retention capacity in sandy and clayey soils. The results of the laboratory measurements were analyzed using NCSS statistical software at a statistical significance of p < 0.05. In sandy soil, there was a statistically significant decrease in ρd and Ks and an increase in Φ and a contact angle (CA) after the application of 1 g/100 cm3 HA. At a dose of 6 g/100 cm3 HA, the values of ρs, ρd, and Ks decreased, and the Φ and CA values increased. In clayey soil, the Ks value significantly decreased by −35.5% only after the application of 6 g/100 cm3 HA. The addition of HA increased the full water capacity (FWC) and available water capacity (AWC) of clayey and sandy soils. The positive influence of HA on the studied soil parameters was experimentally confirmed, which can be beneficial, especially for their use in agricultural production.

Nitrogen adsorption isotherms, along with the BET model for interpretation, are recommended for estimating biochar surface area. The frequently measured small surface areas of biochars contrast with their high sorption and cation exchange capacities. We hypothesised that water adsorption provides a better tool for estimating the surface area of biochars. Although adsorption energy also appears to be a valuable surface characteristic, there is a lack of studies on this subject. We studied the surface areas and adsorption energies of three waste deposits – peat, willow dust and biochar prepared from these materials at different temperatures – using nitrogen and water vapour adsorption isotherms. The BET model accurately described all water vapour adsorption isotherms but failed for some nitrogen isotherms. Alternative methods for estimating surface areas and adsorption energies were proposed in cases where the BET model did not apply. Nitrogen adsorption was typically much lower than water vapour adsorption, and the estimated surface areas reflected this. However, nitrogen adsorption energies were significantly higher. Nitrogen surface areas increased with pyrolysis temperature, while water vapour surface areas decreased. The surface area estimated from nitrogen adsorption was generally much lower than needed to accommodate the surface-charged groups responsible for the cation exchange capacity of biochars.

The accumulation of microplastics (MPs) in agricultural land may threaten food security and farmers' health, which is of interest. This study examined the implication of MPs contamination/pollution on the chemical properties of an Inceptisol on different slopes in the horticultural production center of Banuhampu Subdistrict, Agam District, West Sumatra Province. The soil samples were determined by purposive random sampling with a quantitative survey method. Sample testing was carried out using a randomized completely block design with five treatments, i.e., 25-45% in forests, and 0-8%, 8-15%, 15-25%, and 25-45% in fields at a depth of 0-20 cm. The Inceptisol contaminated with MPs has the following characteristics: pH = 5.01, EC = 0.09 dS m-1, Eh = 92.97 mV, mineral = 68.81%, OM = 31.19%, CEC = 60.67 cmol(+) kg-1, C = 2.13%, N = 0.81%, P2O5 = 6.46 ppm, K = 0.48, Ca = 1.59 cmol(+) kg-1, Mg = 0.62 cmol(+) kg-1 , and SO4 = 98.98 ppm. The concentration of MPs on the Inceptisol was 438.33 particles kg-1 with filament shape, transparent color, and large size (1-5 mm) were the most commonly found. Polymer types included polyamide 6, polystyrene, and polyethylene. The effect of slope level on the surface change charger of Inceptisols contaminated with MPs was insignificant. However, the effect was significant in OC, total N, K-exch, and available S. The implications of microplastic contamination/pollution did not have a significant relationship with the chemical properties of the soil. However, it has a negative relationship to redox potential (Eh), mineral composition, and Ca-exch.
