More exact information on soil nutrient management is crucial due to environmental protection, nature conservation, decreasing sources for mining, general precaution, etc. Soil magnesium (Mg) analytical methods of potassium chloride (KCl), Mehlich 3 (M3), water (WA) and cobalt hexamine (CoHex) extractions are compared with an elemental analysis and X-ray fluorescence (XRF) analysis. The ratio of the available to the total Mg content was calculated and compared on the whole dataset. The results showed that the linear regressions between all the pairs of Mg content measurement methods were significant. The linear relationship between the KCl and CoHex methods has the highest determination coefficient (R2 = 0.96), followed by WA–M3 (R2 = 0.68), M3–CoHex (R2 = 0.66) and M3–KCl (R2 = 0.60). The M3 solution demonstrated a greater capacity for extracting Mg from the soil. The second part is the analysis of the influence of CaCO3, pH, soil texture and clay content on the measurable magnesium content of soils. It was established that the extraction methods, the soil and the classification method of the soil properties affect the evaluation. These results may help through the nutrient replenishment and the melioration of soils. These results can help the examination of mineral nutrients, especially the Mg uptake.
A lakott területeken megjelenő nyestek és azok kártétele napjainkban egyre többször kerül elő, más lakott településen megjelenő vadfajainkkal együtt. A városok és falvak terjeszkedéseinek hatására egyre több élőlény talál otthonra a lakott területeken és ennek következtében a lakosság és a ragadozó fajok közti konfliktusok száma megnövekszik. A vizsgálat során két lakott településen (Szárliget, Tata) előforduló nyestek kártételét próbáltuk felmérni kérdőív segítségével. A kérdőíves felmérés eredményeit kiegészítendő szőrcsapdákat és műfészkeket helyeztünk ki a településeken a ragadozók előfordulásának objektív vizsgálatára. A kutatás során a következőkre kerestük a választ: mely időszakokban történtek a károk, mit károsítottak a leggyakrabban a nyestek, és hogy mekkora a különbség a város és falu közt a károsítások terén. A védekezés és riasztás szempontjából mindkét településen, az interneten terjedő praktikákkal (pl. vizes palack elhelyezése a gépjárművek körül) próbálkoznak a legtöbben, amely sikertelen szokott lenni. Mindkét településen a személygépjárműveket károsították a legtöbbet, és azon belül is a kábelek megrágásával okoztak leggyakrabban kárt. A kihelyezett szőrcsapdákat Szárligeten macskák keresték fel, a műfészkeket szintén macskák, vagy madarak illetve kóbor kutyák. A szőrcsapda és műfészek felmérésből jól látszik a mind két településen nagy számban jelen lévő kóbor kutyák és macskák jelenléte. Összességében elmondható, hogy a kérdőíves felmérés eredményei igazolják a hazai és külföldi szakirodalmakat és publikációkat a nyest városi jelenlétéről és károkozásáról.
The current study compares the phosphorus (P) analysis methods of ammonium lactate (AL), Mehlich 3 (M3); water extraction (P-WA(P)&P-WA(PO4)), cobalt hexamine (CoHex) and X-ray fluorescence (XRF) as an estimate of total soil P. The ratio of the P-content/XRF was first calculated and compared with the whole dataset. Based on the comparison of all the data, there were significant differences between the results of P-WA(P) and P-WA(PO4) vs. M3 and AL, CoHex vs. M3 and CoHex vs. AL methods (p < 0.001). The second step was the analysis of the influencing factors based on their categories for a more in-depth understanding of their role (CaCO3-content, pH, soil texture and clay content). The results showed that higher CaCO3 content (>1%) resulted in lower correlations (6/10 cases). The extraction methods, the soil, the classification method of the soil properties and the statistical analyses affect the evaluation. The dataset covers a good range of the analysed factors for the evaluation of phosphorus in the majority of Hungarian soil types in arable use. There were two methods that detected the largest amount of P from the total P in the soil: AL and M3.
Agriculture has always played a determining role in Hungarian landscapes. Forested areas were also under agricultural use; however, their use changed, starting at least from the Middle Ages when the need for new arable fields resulted in a tremendous decrease in forested areas. The protection of forests started for many reasons, saving them for fuelwood and construction materials. This is the reason why there were periods when forests of the Carpathian Basin suffered from considerable pressure, and even today, this pressure continues; however, the source changed from animal husbandry to tourism, forestry, and wildlife management, or rather hunting. This created the need to search for and analyse former sustainable use of the forests. Furthermore, the consideration of the use of trees/treelines is under the scope of helping the climate adaptation of arable fields. Wooded grasslands have also been mapped and various analyses were done, related to their survival. We wish to introduce some of the ancestral forms of the agricultural use of Hungarian farming, where trees play an important role, their origin, distribution, threatening factors, and their future. Sustainable arable farming systems with trees, including wood-pastures; orchard grasslands and conventional, organic, and permaculture horticultural farms with various proportion of tree cover, will be described.
Abstract A useful method to evaluate the effectiveness of soil‐erosion models is to compare the models' soil‐loss and runoff calculations with measured data from experimental plots subjected to artificial rainfall. This study was conducted to develop a set of statistics to compare the performance of the soil‐erosion models EUROSEM, WEPP, and MEDRUSH. Rainfall (six rainfall intensities, two replicates), runoff, and soil‐loss data from artificial plots at two locations in Hungary were used to assess the accuracy of the different models. The soil types within the plots represented a wide range of soil properties and are soil types that are commonly used for agriculture. The results showed that the three soil‐erosion models performed with varying effectiveness dependent on basic soil properties. However, statistical analysis showed the EUROSEM model to be the best for estimating soil loss in Hungary.
The European wildcat population of Hungary is threatened by habitat loss and fragmentation, and additionally, by hybridization with domestic cats. Responsible cat ownership would be of paramount importance for the prevention of unwanted hybridization between the two species. In a questionnaire survey, Hungarian cat owners and non-owners were asked about their knowledge regarding responsible cat ownership and their actual cat keeping practices. Additionally, we also surveyed whether they realized the various anthropogenic dangers (including domestic cats) that threaten the wildcat population. Based on the answers of 1322 respondents, we discovered several warning signs that indicate worrisome tendencies. Cat owners consider cats as the least serious concern for wildcat conservation, and even knowledgeable participants with wildlife-related education continue irresponsible cat ownership practices. While many participants consider safe and responsible cat keeping as important, and actively engage in the prevention of unwanted predatory and roaming activities of their cats, a considerable cohort of Hungarian cat owners consider their animals to be expendable property and refrain from implementing any measure of responsible cat keeping. This is the first study where the same respondents were surveyed for their cat keeping habits and their knowledge about some aspects of wildcat conservation. Although Hungarian cat owners show considerable knowledge about responsible cat keeping, in reality, there is still room for improvement. The lessons learned in Hungary, where the wildcat population is still considered viable, could bear high relevance for any country where wildcat conservation against the effects of privately owned domestic cats represents a problem.
