“…Our study involved soil without canopy cover. This can be considered as an extreme case, where the highest level of soil loss occurs through all types of erosion, including splash erosion (Brant et al, 2017). On the basis of earlier studies (Römkens et al, 2002;Legout et al, 2005;Ryzak et al, 2015;Hänsel et al, 2016;Fernández-Raga et al, 2017), the greatest influence on splash mass has been attributed to a combination of grain size distribution and aggregate stability, which is also influenced by the (Kalantari, 2012).…”

An understanding of splash erosion is the basis to describe the impact of rain characteristics on soil disturbance. In typical splash cup experiments, splashed soil is collected, filtered, and weighed. As a way to collect additional data, our experiments have been supplemented by a photogrammetric approach. A total of three soils were tested across three sites, one in the Czech Republic and two in Austria, all equipped with rain gauges and disdrometers to measure rainfall parameters. The structure from motion multiview stereo (SfM-MVS) photogrammetric method was used to measure the raindrops impact on the soil surface. The images were processed using Agisoft PhotoScan, resulting in orthophotos and digital elevation models (DEMs) with a resolution of 0.1 mm/pix. The surface statistics included the mean surface height (whose standard deviation was used as a measure of surface roughness), slope, and other parameters. These parameters were evaluated depending on soil

“…We must protect soil as one part of the earth's ecosystem, especially in the future, due to environmental changes, because soil plays a key role in the production of agricultural crops and subsequently food (an important factor in maintaining food quality and safety, human health and the sustainability of entire ecosystems) [14,19,20]. The conditions of agricultural production have changed drastically (reduction of human labour, inappropriate crop rotation, reduced livestock production, low manure production and thus the supply of organic matter into the soil and dependence on the mineral nitrogen) [21,22]. The problem of soil erosion goes hand in hand with the recent changes in agricultural production [17].…”

“…The most significant degradation factor in the Czech Republic is water erosion [23][24][25][26], followed by soil organic matter loss [20,26]). More than 50% of the arable land is potentially endangered by water erosion [21,26,27]. In the Czech Republic, the Universal Soil Loss Equation (USLE) is used to determine the vulnerability of soil to water erosion [28][29][30] and to evaluate the effectiveness of the proposed measures [31,32].…”

“…One of the many options for soil conservation measurement is the use of Strip-Till technology [39], which is commonly used mainly in the USA and Canada [48], and is gradually spreading throughout Europe [21,49]. Using the Strip-Till technology for broad-row crops (maize, or sunflower) can improve soil quality, decrease soil erosion and protect the environment [32,50].…”

In today’s agriculture, maize is considered to be one of the major feed, food and industrial crops. Cultivation of maize by inappropriate agricultural practices and on unsuitable sites is connected with specific risks of soil degradation, mainly due to water erosion of the soil. The aim of this study was to evaluate the yielding parameters, fodder quality and anti-erosion efficiency of different methods of conservation tillage for maize in two areas (Jevíčko—JEV and Skoupý—SKO) with different climate and soil conditions in the Czech Republic in the period 2016–2018, using multivariate exploratory techniques such as principal component analysis (PCA) and factor analysis (FA). Four variants of soil tillage methods were analysed: Conventional Tillage (CT), two slightly different Strip-Till techniques (ST) and Direct Sowing (DS). The analysed parameters were: dry mass of the plants, height of the plants, starch content (SC), organic matter digestibility (OMD) and content of neutral detergent fibre (NDF), soil loss by erosion and surface runoff. The multivariate exploratory techniques PCA and FA significantly differed in two categories of techniques in both locations. The first category consists of soil conservation techniques (SCT): ST (JEV/SKO) and DS (JEV). These techniques are characterised by lower yields of dry mass, lower height of plants, forage quality equal to CT, but a high level of protection of the soil against erosion. The second category consists of CT (JEV and SKO) and partially of DS (SKO). These treatments are characterised by high dry mass production, higher plants, high forage quality, but a feeble capacity of protection of the soil against erosion. The results of the study confirm the presumption of the positive influence of introduction and application of new agronomical practices in the areas of interest and other areas with similar natural conditions in the sense of sustainable management for agricultural management of agricultural land for the conditions of the Czech Republic and therefore of Central and Eastern Europe. PCA and FA were used as an effective method for comprehensive evaluation of the use of STC in agricultural practice.

“…Intensification of maize cultivation for silage production requires not only placing it in specialized crop rotations, but also making correct scientific justification for the selection of green manure, ensuring the increased productivity of high-quality silage mass with the lowest costs, while preserving the fertility of the soil [16,[22][23][24].…”

Main elements of nutrition content in the soil for maize crops, depending on the predecessors and methods of soil treatment

The article presents data on the study of the main nutrition elements in the soil under maize crops, depending on the predecessors and methods of soil treatment in the conditions of ordinary Chernozem. The object of research is a Krasnodarsky 194MV hybrid of maize. Variants: 1. Fallow arable land (control); 2. Lupine as green manure; 3. Peas as green manure; 4. Binary sowing of lupine and peas as green manure; 5. Soy as green manure. The experiment was repeated three times, field placement was randomized, and area of each was 120 m². Agrotechnics of maize cultivation in the experiment corresponded to the recommendations for this zone. Green manure was plowed in during its reproduction phase. In the variants with green mass plowing to a depth of 23–25 cm, the largest amount of nitrate nitrogen was in the soil layer 0–20 cm. In the specified soil horizon, before sowing maize, the content of nitrate nitrogen ranged, depending on the variant, from 24.7 mg/kg to 42.8 mg/kg. In the soil layer 20–40 cm, the amount of nitrogen was lower, just 19.4–29.5 mg/kg. Similar dependence was observed for maize during its flowering phase. Tillage methods had almost no effect on the accumulation of nitrate nitrogen in the upper soil layer (0–20 cm). As in all the variants, the differences in this indicator were within the experimental error. However, the content of nitrate nitrogen during the growing season was different. The greatest amount of it was observed during the spring period, both in versions with plowing to a depth of 25–28 cm and in versions with blade loosening to a depth of 10–12 cm. The smallest amount of available phosphorus, regardless of the method of soil preparation, in the layer 0–20 cm was on fallow arable land – 122 mg/kg during the sowing period and 104 mg/kg during the flowering period. In variants with cultivation of legumes as green manure, the content of available phosphorus in the specified horizon was significantly chigher, being 147–171 mg/kg. The highest content of exchangeable potassium was provided by lupine – 209–213 mg/kg in the 0–20 cm soil layer, and lupine sown together with peas – 196–207 mg/kg. The minimum amount of exchangeable potassium was 143–146 mg/kg in fallow arable land, depending on the method of soil treatment.
