Therefore, broken and intact soil samples are taken regularly and laboratory analyses are carried out. The\u00a0chosen site is\u00a0located in\u00a0the\u00a0\u0160ardice cadastral area, Hodon\u00edn district, South Moravian region. At the\u00a0chosen site it is\u00a0possible to\u00a0consider grass strips with one or\u00a0more rows of\u00a0trees as\u00a0a\u00a0possible agroforestry system, where temperature and humidity are measured continuously by\u00a0TOMST TMS-4 moisture sensors.

We can influence them both positively and negatively.<\/p>\n<h2>INTRODUCTION<\/h2>\n<p>Due to\u00a0current climate change, where increasing average annual temperatures are leading to\u00a0more frequent extremes such as\u00a0torrential rainfall and longer periods of\u00a0drought, great emphasis\u00a0is\u00a0placed on\u00a0returning the\u00a0landscape to\u00a0its original state, or\u00a0at least as\u00a0close to\u00a0this\u00a0state as\u00a0possible. Over the\u00a0past few decades, our agricultural landscape has\u00a0not been managed in\u00a0an ideal way, and therefore it is\u00a0necessary to\u00a0pay attention\u00a0to\u00a0this\u00a0issue, especially the\u00a0design of\u00a0protective and adaptation\u00a0measures. Land is\u00a0the\u00a0most valuable natural resource that every country has, and it is\u00a0also non-renewable [1].<\/p>\n<p>In\u00a0the\u00a0Czech Republic, soil is\u00a0mainly threatened by\u00a0water and wind erosion\u00a0[2]. The\u00a0effect of\u00a0water erosion\u00a0on\u00a0the\u00a0soil is\u00a0manifested by\u00a0leaching of\u00a0organic and mineral particles from the\u00a0soil and the\u00a0transport of\u00a0sediments from eroded areas. Subsequently, when the\u00a0terrain\u00a0slope decreases, they are stored in\u00a0places of\u00a0accumulation\u00a0[3]. Other negative effects include damage to\u00a0built-up areas, siltation\u00a0of\u00a0watercourses and reservoirs, and penetration\u00a0of\u00a0residues from agrochemicals and hazardous substances into\u00a0the\u00a0aquatic environment.<\/p>\n<p>With intensive agricultural production\u00a0on\u00a0arable land and livestock production, it is\u00a0possible to\u00a0achieve high yields per unit of\u00a0area and work, but they can negatively affect the\u00a0environment. The\u00a0design and implementation\u00a0of\u00a0agroforestry systems can be a\u00a0contribution\u00a0to\u00a0mitigating climate change, improving landscape water management, supporting landscape biodiversity, and also creating a\u00a0friendlier environment for\u00a0humans.<\/p>\n<p>The\u00a0aim of\u00a0this\u00a0article is\u00a0to\u00a0evaluate the\u00a0influence of\u00a0agroforestry systems, the\u00a0method of\u00a0cultivation, and land use on\u00a0the\u00a0complex of\u00a0soil hydropedological properties and the\u00a0flow of\u00a0moisture.<\/p>\n<h2>METHODOLOGY<\/h2>\n<h3>Agroforestry system and its effect on\u00a0the\u00a0landscape<\/h3>\n<p>Agroforestry takes advantage of\u00a0the\u00a0combination\u00a0of\u00a0trees, shrubs, and livestock and their interaction. Agricultural and forestry technologies are both used. Agroforestry systems (AFS) use trees and shrubs in\u00a0a\u00a0targeted manner in\u00a0agriculture, or\u00a0possibly use forest products other than wood [4].<\/p>\n<p>There are several definitions of\u00a0agroforestry according to\u00a0the\u00a0time and place of\u00a0origin. Despite many partial ambiguities in\u00a0its definition, common\u00a0guidelines for\u00a0all agroforestry systems are the\u00a0following:<\/p>\n<ul>\n<li>economic activity including both agricultural production\u00a0and that provided by\u00a0trees or\u00a0shrubs,<\/li>\n<li>interconnectedness between these sub-components of the systems,<\/li>\n<li>emphasis on other non-production functions, or persistence of the system,<\/li>\n<li>the importance of the human role in the system.<\/li>\n<\/ul>\n<p>There are a\u00a0number of\u00a0agroforestry systems. The\u00a0methodology according to\u00a0Dupraz et al. was\u00a0used for\u00a0basic classification\u00a0of\u00a0agroforestry and the\u00a0European Agroforestry Federation\u00a0EURAF. Using it, it is\u00a0possible to\u00a0define the\u00a0basic categories of\u00a0agroforestry on\u00a0agricultural land [5]:<\/p>\n<p><strong>Agrisilvicultural<\/strong> \u2013 cultivation\u00a0of\u00a0woody plants on\u00a0arable land, agricultural-forestry system, including woody plants and agricultural crops on\u00a0the\u00a0same plot of\u00a0land. Some commonly used agrisilvicultural systems are thus made up of\u00a0cultivated lanes and hedges (Fig. 1 and 2).<\/p>\n<p><strong>Silvopastoral<\/strong> \u2013 cultivation\u00a0of\u00a0woody plants on\u00a0permanent grasslands, grazing-forestry system, grazing, animals grazing grass in\u00a0AFS (Fig. 3).<\/p>\n<p><strong>Agrosilvopastoral<\/strong> \u2013 Agricultural-grazing-forestry system \u2013 i.e., cultivation\u00a0of\u00a0crops and trees combined with animal breeding.<\/p>\n<p>AFS has\u00a0the\u00a0potential to\u00a0be a\u00a0tool for\u00a0combining climate change, protecting people and property, and creating the\u00a0foundations for\u00a0a\u00a0more sustainable economy and for\u00a0social development. Sustainable forest management provides a\u00a0framework for\u00a0planning at international and national levels and is\u00a0one way to\u00a0address an ever-changing climate. At the\u00a0same time, AFS has\u00a0the\u00a0potential to\u00a0contribute to\u00a0the\u00a0field of\u00a0adaptation\u00a0strategies. These support sustainable management and community practices and have the\u00a0potential not only to\u00a0protect land and people from the\u00a0adverse effects of\u00a0climate change, but also provide an opportunity for\u00a0greater and more sustainable rural development. These systems offer farmers opportunities in\u00a0production\u00a0diversity, risk reduction\u00a0in\u00a0farming (production), food security, and much-needed income generation. Further on, they can satisfy the\u00a0commercial need for\u00a0wood and improve environmental conditions. Thanks to\u00a0agroforestry measures, a\u00a0large number of\u00a0trees are now harvested outside conventional forest plots [6].<\/p>\n<h6><a href=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-1.jpg\" rel=\"shadowbox[sbpost-21118];player=img;\"><img decoding=\"async\" width=\"800\" height=\"398\" class=\"alignleft size-full wp-image-18681 lazyload\" data-src=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-1.jpg\" alt=\"\" data-srcset=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-1.jpg 800w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-1-300x149.jpg 300w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-1-768x382.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/398;\" \/><\/a>Fig. 1.

Hor\u00e1kov\u00e1)<\/h6>\n<p>The\u00a0interaction\u00a0between trees and crops can be studied in\u00a0positive, negative, and neutral way. These interactions are dependent on\u00a0the\u00a0type of\u00a0model used involving different variants of\u00a0species, their nature, and arrangement. The\u00a0interaction\u00a0is\u00a0further defined as\u00a0the\u00a0influence of\u00a0one part of\u00a0the\u00a0system on\u00a0the\u00a0behaviour of\u00a0another part of\u00a0the\u00a0system and\/or\u00a0the\u00a0entire system [7]. Various interactions occur between trees and plants (crops and pastures). Studying the\u00a0interaction\u00a0between trees and crops within\u00a0agroforestry could help find appropriate ways to\u00a0increase overall soil productivity. The\u00a0main\u00a0positive effects of\u00a0interaction\u00a0are increased productivity, better soil fertility, nutrient cycling, and soil protection. The\u00a0main\u00a0negative effect of\u00a0interaction\u00a0is\u00a0their competition, which reduces crop yields. This\u00a0can be due to\u00a0the\u00a0space, light, nutrients, and moisture they need. The\u00a0ecological sustainability and success of\u00a0any agroforestry system is\u00a0dependent on\u00a0the\u00a0interaction\u00a0and complementarity between positive and negative effects. An agroforestry system can bring an overall positive result only when positive effects outweigh negative ones [8].<\/p>\n<p>Soil properties in\u00a0agroforestry systems depend on\u00a0tree species and their intermingling, management practices, arrangement, quantity and quality of\u00a0litter, and its rate of\u00a0decomposition. Trees are planted in\u00a0rows parallel to\u00a0arable land with crops. These trees provide food, wood, fuel, fodder, building materials, raw materials for\u00a0small forestry enterprises, and in\u00a0some cases enrich the\u00a0soil with essential nutrients [9].<\/p>\n<p>Planting trees and their sustainability can help protect soil against the\u00a0adverse effects of\u00a0torrential rainfall. In\u00a0addition, agroforestry systems can be used to\u00a0recultivate degraded land and maintain\u00a0water quality by\u00a0capturing sediments, nutrients, and toxic substances. They also have the\u00a0potential to\u00a0move water from significantly deeper layers where water is\u00a0found to\u00a0layers that are drier and in\u00a0a\u00a0higher soil profile. This\u00a0process has\u00a0been described both in\u00a0naturally occurring compositions of\u00a0trees and grasses and in\u00a0agroforestry systems [10].<\/p>\n<p>In\u00a0general, unprotected soil receives more sunlight than protected soil, and temperature follows the\u00a0same trend. Many studies have shown that agroforestry systems perform better than a\u00a0stand-alone cropping system in\u00a0areas\u00a0where there is\u00a0either a\u00a0shortage of\u00a0groundwater or\u00a0less atmospheric precipitation. Agroforestry is\u00a0a\u00a0good tool for\u00a0crops that like shade and lower temperatures. Trees bring favourable changes in\u00a0microclimatic conditions due to\u00a0the\u00a0influence of\u00a0radiation\u00a0flow, air temperature, wind speed, and saturation\u00a0deficit of\u00a0supplementary crops, which can have a\u00a0significant impact on\u00a0modifying the\u00a0rate and duration\u00a0of\u00a0photosynthesis\u00a0and subsequent plant growth, transpiration, and soil water use [11]. The\u00a0shade of\u00a0trees plays an important role in\u00a0reducing evapotranspiration, reducing temperature, and increasing humidity. By\u00a0removing trees, soil temperature can increase by\u00a0about 4 \u00b0C and the\u00a0relative humidity of\u00a0the\u00a0air can decrease by\u00a0about 12 % up to\u00a02 m above the\u00a0ground [12].<\/p>\n<h3>Research site<\/h3>\n<p>As\u00a0part of\u00a0complex land improvements in\u00a0the\u00a0plan of\u00a0common\u00a0facilities (in\u00a0addition\u00a0to\u00a0the\u00a0design of\u00a0the\u00a0field\/farm track network) in\u00a0the\u00a0\u0160ardice cadastral area, anti-flood and anti-erosion\u00a0measures were proposed in\u00a0connection\u00a0with the\u00a0territorial system of\u00a0ecological stability. As\u00a0part of\u00a0these multifunctional measures, in\u00a0five locations \u2013 in\u00a0order to\u00a0adjust erosion\u00a0and runoff conditions \u2013 ecological balance was\u00a0achieved and various types of\u00a0degradation\u00a0of\u00a0agriculturally used land were mitigated. Among the\u00a0measures applied within\u00a0the\u00a0plan of\u00a0common\u00a0facilities are organizational measures (i.e., optimal delimitation\u00a0of\u00a0land types), protective grassing on\u00a0erosion-prone locations, anti-erosion\u00a0distribution\u00a0of\u00a0crops on\u00a0slopes, belt rotation\u00a0of\u00a0crops, and anti-erosion\u00a0distribution\u00a0of\u00a0crops. As\u00a0part of\u00a0the\u00a0agrotechnical measures, there was\u00a0sowing in\u00a0a\u00a0protective crop, stubble, mulch or\u00a0post-harvest residues, grassing the\u00a0erosion-threatened intermediate rows in\u00a0orchards and vineyards in\u00a0order to\u00a0retain\u00a0rainwater on\u00a0the\u00a0soil surface, and contour cultivation.

The\u00a0first number in\u00a0the\u00a0marking indicates the\u00a0position\u00a0on\u00a0the\u00a0slope, i.e. 1 = top, 2 = in\u00a0the\u00a0middle, and 3 = bottom; the\u00a0second number in\u00a0the\u00a0marking is\u00a0the\u00a0location\u00a0within\u00a0the\u00a0position\u00a0on\u00a0the\u00a0slope (see the\u00a0previous sentence). Furthermore, a\u00a0comparison\u00a0of\u00a0the\u00a0physical properties from strip A, from the\u00a0first (4\/2020) and the\u00a0last (4\/2022) spring collection, will be presented.<\/p>\n<p>In\u00a0Fig. 8, 10, and 12 (which are graphs for\u00a0a\u00a0depth of\u00a020 cm) it can be seen that there is\u00a0a\u00a0rapid increase in\u00a0soil moisture after rainfall. In\u00a0the\u00a0period without precipitation\u00a0it is\u00a0then reduced. The\u00a0values for\u00a0a\u00a0depth of\u00a020 cm range from 0.1\u20130.55 (i.e., 10\u201355 %), depending on\u00a0the\u00a0intensity and amount of\u00a0precipitation. At\u00a0a\u00a0depth of\u00a050 cm (Fig. 9, 11, and 13), soil moisture is\u00a0quite balanced throughout the\u00a0period and there are no sudden changes depending on\u00a0the\u00a0current precipitation; the\u00a0values range from 0.05 to\u00a00.4 (i.e., 5\u201340 %). Compared to\u00a0a\u00a0depth of\u00a020\u00a0cm, the\u00a0values are lower, but more balanced. The\u00a0exceptions are two positions, namely a\u00a03\u20132 (the\u00a0lower part of\u00a0the\u00a0slope near the\u00a0tree \u2013 Fig. 11) and a\u00a03\u20133 (the\u00a0lower part of\u00a0the\u00a0slope, the\u00a0edge of\u00a0arable land \u2013 Fig. 13). This\u00a0jump increase can be explained by\u00a0their location\u00a0on\u00a0the\u00a0slope. Both positions are located in\u00a0the\u00a0lower part, which means that there is\u00a0surface runoff within\u00a0this\u00a0area, and in\u00a0this\u00a0place the\u00a0water is\u00a0retained and absorbed to\u00a0a\u00a0greater extent.<\/p>\n<h6><a href=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-8-1.jpg\" rel=\"shadowbox[sbpost-21118];player=img;\"><img decoding=\"async\" width=\"800\" height=\"254\" class=\"alignleft size-full wp-image-18929 lazyload\" data-src=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-8-1.jpg\" alt=\"\" data-srcset=\"https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-8-1.jpg 800w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-8-1-300x95.jpg 300w, https:\/\/www.vtei.cz\/wp-content\/uploads\/2023\/04\/Horakova-obr-8-1-768x244.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/254;\" \/><\/a>Fig. 8.

According to\u00a0Nov\u00e1k, the\u00a0samples were then classified (Tab. 1) as\u00a0either light \u2013 loamy sand (LS), medium \u2013 sandy loam (SL), or\u00a0loam (L) soil. Limit values for\u00a0physical properties and hydrolimits are then determined on\u00a0the\u00a0basis\u00a0of\u00a0grain\u00a0size analysis\u00a0(see below in\u00a0the\u00a0text).<\/p>\n<p>Selected physical properties and hydrolimits were evaluated from intact soil samples. The\u00a0results from April 2020 and 2022 were selected for\u00a0the\u00a0example. Changes in\u00a0the\u00a0evaluated parameters are visible from them (Tab. 2 and 3 \u2013 depth 20 cm, Tab. 4 and 5 \u2013 depth 50 cm).

The\u00a0data obtained from the\u00a0moisture sensors will be subjected to\u00a0statistical analysis, which will examine and compare whether and to\u00a0what extent slope position, habitat location\u00a0(arable land, grass strip), season, and amount of\u00a0precipitation\u00a0affect change in\u00a0humidity (at both depths).<\/span><\/p>\n<p class=\"00TEXTenglish\"><span lang=\"EN-GB\">The above data show that slope position (slope of the land) and the way the land is used has an influence on the course of moisture and resulting physical parameters of the soil. For the selected periods of 4\/2020 and 4\/2022, the best values are at a depth of 20 cm for the position A 2\u20132 (in the middle of the slope near the tree) and a 3\u20131 (the lower part of the slope between the trees), both from the point of view of the course of humidity, as well as in terms of physical parameters. For both positions, only the aeration value is not satisfactory; it is outside the optimal value for a topsoil horizon in good condition. However, when comparing results from the first sampling with the last one, values\u00a0<\/span><span lang=\"EN-GB\">for\u00a0the\u00a0positions in\u00a0the\u00a0grass strip with trees worsened. On\u00a0the\u00a0other hand, for\u00a0arable land, the\u00a0values are rather balanced, without major\u00a0fluctuations.<\/span><\/p>\n<p class=\"00TEXTenglish\"><span lang=\"EN-GB\">The\u00a0final evaluation\u00a0of\u00a0agroforestry systems shows that they cannot avert ongoing climate change, but they can help mitigate negative impacts on\u00a0the\u00a0landscape, especially by\u00a0mitigating erosion\u00a0(both wind and water) and by\u00a0retaining precipitation\u00a0in\u00a0the\u00a0landscape, i.e., by\u00a0increasing infiltration\u00a0and reducing direct surface runoff, which is\u00a0important due to\u00a0the\u00a0volatility of\u00a0rainfall (long periods without rainfall or\u00a0torrential rainfall). Overall, it can be concluded that the\u00a0landscape is\u00a0returning to\u00a0a\u00a0better appearance and wildlife is\u00a0also returning to\u00a0it.<\/span><\/p>\n<p class=\"00TEXTenglish\"><span lang=\"EN-GB\">The\u00a0research is\u00a0still ongoing and will be expanded by\u00a0experiments using a\u00a0deep aeration\u00a0device, which should help in\u00a0aerating the\u00a0soil horizon\u00a0at\u00a0the\u00a0required depth, thereby\u00a0improving the\u00a0infiltration\u00a0capacity of\u00a0the\u00a0soil.
