“…Measurements. The used field rainfall simulator (the rainfall simulation area = 21 m, with a rainfall https://doi.org/10.17221/36/2022-SWR intensity of 1.2 mm/min) plus the principles of measurement are described in different publications (e.g., Kabelka et al 2019Kabelka et al , 2021Kincl et al 2021). All the rainfall simulations were performed twice consecutively (the first measurement = 30 min of simulated rainfall on the soil with natural moisture; after a 15 min technological break, a second rainfall simulation for 15 min was performed on the same saturated soil).…”

More than 50% of agricultural land is threatened by water erosion in the Czech Republic. With respect to soil erosion, maize (Zea mays L.) belongs to the most problematic crops; one of the possibilities to increase protection against erosion is intercropping. In this study, we attempted to find out the effects of individual intercrops and their mixtures (sown 4–6 weeks after sowing maize) or a mixed culture (maize plus lupine) on the soil losses and surface runoff in the period 2019–2021. The study was realised in a sugar beet growing region (Haplic Luvisol); a field rainfall simulator was used. From the used variants with Lolium perenne L., Trifolium repens L., Vicia villosa Roth, Lolium multiflorum Lam., Festuca arundinacea Schreb., Triticum aestivum L. or a mixture (Vicia villosa plus a Trifolium hybrid diploid), the variants with Lolium perenne, Lolium multiflorum, Vicia villosa or Vicia villosa plus the Trifolium hybrid diploid, established between the maize rows (hybrid maize, cultivar Walterinio) on May 27, were the most efficient in case of both the soil losses and runoff reductions in the year 2019. For example, Triticum aestivum between the maize rows mostly reduced the soil losses and the surface runoff was similar (or higher) compared with the control (maize without any intercrop). The variant with Trifolium repens had mostly higher (or similar) soil loss values (compared with the control); in this variant, the runoff was lower compared with the control. We proved our hypothesis with regards to the higher reduction in the soil losses than with the runoff in the variant with Lolium perenne. The results from the years 2020 (the used variants with Lolium multiflorum, Secale cereale L., Trifolium incarnatum L., Phacelia tanacetifolia Benth., Lolium multiflorum plus Trifolium incarnatum, Lolium multiflorum plus Vicia pannonica Crantz) and 2021 (the variants with Lolium multiflorum, Lolium multiflorum – early sowing, Secale cereale, Trifolium incarnatum, Phacelia tanacetifolia, Lolium multiflorum plus Trifolium incarnatum, a mixed culture = maize plus Lupinus albus L.) showed the variants with Trifolium incarnatum, the mixture (Lolium multiflorum plus Trifolium incarnatum), Phacelia tanacetifolia (in the year 2020) or the mixture (Lolium multiflorum plus Trifolium incarnatum) and a mixed culture (maize plus Lupinus albus) (2021) had the most positive effect – the soil loss and surface runoff values were lower when the maize was > 2 m compared with the maize < 1 m. The results obtained in the period 2019–2021 showed the grasses were the most efficient in decreasing the soil losses when the maize was < 1 m and when the maize was > 2 m with the used mixtures.

“…In our experiment, maize shreddings were studied from two sites where maize was grown by the original and innovative technology. The reason for using the innovative technology (with new undersown crops) was an effort to reduce the impact of growing maize on arable land (Kabelka et al, 2021), namely the risk of water erosion. Apart from that, the method of growing maize affects also other parameters such as yield and quality of maize shreddings, i.e., also the content of mycotoxins in them (Drakopoulos et al, 2021).…”

Licensed under a Creative Commons Attribution 4.0 International LicenseThe effect of growing maize with undersown crops on the content of mycotoxins in maize biomass was studied. Small plot experiments were conducted in 2019 on two sites with different soil and climatic conditions: Žabčice and Troubsko. Three treatments of intermediate crops (Italian ryegrass; Fodder vetch and a mixture of both) were undersown into the space between the rows of maize. The maize was harvested at a dry matter content of 35% at the Troubsko experimental site and 43% at the Žabčice experimental site. After the harvest of maize, samples of green biomass (shreddings) were dried at 60 °C and then analyzed for the content of mycotoxins such as deoxynivalenol (DON), aflatoxin (AF, L), and fumonisin (FUM). An average yield of maize shreddings ranged from 16.50 to 21.57 t/ha of dry matter within the individual treatment. The contents of mycotoxins from the sites differed in their statistical significance, and both experimental sites showed the lowest concentrations of AFL in maize shreddings while average concentrations of FUM and DON were always the highest. In most observations, treatments with the undersown crops reached the same values as the control treatment. Only in one treatment (mixture of Italian rye grass and Fodder vetch), an increase in the AFL content (by 0.3 µg/kg) was detected. Based on the performed analyses, it is possible to state that no adverse influence of undersown crops on the occurrence of mycotoxins in maize shreddings was recorded using the chosen methodology of cultivation. Exceeded limit values for the content of mycotoxins in feeds according to 2006/576/were not recorded.

“…Rainfall is often considered to be the main soil erosion agent (Pimentel & Kounang 1998), which is why special attention is paid to the rain-soil relationship and its erosive effects (Lee & Hsu 2021). Furthermore, it is generally accepted that the erodability of soil will depend greatly on its physical and chemical properties, although the type of vegetation cover has a decisive influence as well (Zhou et al 2008;Çomakli & Turgut 2021;Kabelka et al 2021). Another significant aspect to consider is land slope.…”

Life Cycle Assessment (LCA) is normally used independently of the physical and temporal location of the product, process or service under analysis. This makes LCA results more easily comparable and globally accepted. At the same time, it has drawbacks though, e.g. land use will have the same impact regardless of location. However, the use of certain terrains in high erosion risk areas as compared to others in low erosion risk areas will have a different impact on the ecosystem. The availability of airborne Light Detection and Ranging (LiDAR) data (ALS) allows a quick and accurate morphogeometric analysis of any terrain. For this reason, this article offers a methodology, based on Revised Universal Soil Loss Equation (RUSLE) method and airborne LiDAR data, for the straightforward detection of zones with high vulnerability to erosion problems. Based on these local erosion risk data, a method is developed to assess the environmental impact of land use, based on its location. In this way, the LCA methodology is incorporated to gather local data, dependent on the specific location of the activity under analysis. The methodology developed has been applied, as a case study, to a specific municipality in the high mountains of the Autonomous Community of La Rioja (Spain).
