Abstract Biochar is widely recognized as an amendment that enhances soil properties and sequesters carbon, particularly in degraded soils. However, biochar applied solely to may also hinder plant development due toxic by-products generated during pyrolysis or nutrient retention. To mitigate these adverse effects, it has been suggested either mix with compost process by composting fresh organic materials. date, there a lack of comparative studies evaluating the performance two approaches. In...
Enhanced nitrogen (N) levels accelerate expansion of Calamagrostis epigejos and Arrhenatherum elatius, highly aggressive expanders displacing original dry acidophilous grassland vegetation in the Podyjí National Park (Czech Republic). We compared capability under control N enhanced treatments to (i) accumulate phosphorus (P) plant tissues, (ii) remove P from above-ground biomass during senescence (iii) release material decomposition fresh formed litter. In treatment, significantly higher...
Abstract Question Is a lowland grassland community with lower amount of ambient precipitation and high abundance subdominant species more sensitive to altered rainfall input in comparison mountain higher low species? Location (1) Lowland Festuca characterized by dry acidophilous vegetation, mean annual richness, (2) N ardus richness the E astern C zech R epublic. Methods We conducted manipulative experiment rainout shelters gravity irrigation systems. simulated three levels (50%, 100% 150%)...
The use of biochar in combination with mineral or biological amendments to improve its influence on soil-plant properties has received growing attention. changes nitrogen, carbon and phosphorus content Lactuca sativa var. capitata aboveground plant biomass soil after the addition beech wood combined bacterial inoculums (Bacofil Novarefm) nitrogen fertilizer have been studied using spectrophotometry methods. Pots were filled arable from plots protection zone water sources (Březová nad...
This study evaluated the influence of arbuscular mycorrhizal fungi (AMF) inoculation leek (Allium porrum L.) on leaching ammonia and nitrate nitrogen from experimental pots filled with either sterile or non-sterile soil mix, consisting equally arable horticultural substrate. Leek plants were inoculated by Funneliformis mosseae, Claroideoglomus claroideum, Rhizophagus intraradices their combinations. Based obtained data, it can be concluded that: (a) AMF does not follow some simple rules, (b)...
The area of interest is located in the Sierra de los Filabres semi-arid steppe province Almeria Spain.The amount water soil a limiting factor and its availability aff ects structure species composition ecosystem.On other hand, type vegetation loss via evapotranspiration thus microclimate.It has great infl uence on growth activity microbial communities hence dynamics decomposition organic matter nutrient availability.The aim this study was to assess intensity transformations nitrogen describe...
Abstract Effects of extra nitrogen (N) input on biomass production, the concentration N and phosphorus (P) in plant material, net mineralization were studied during three growing seasons a dry acidophilous grassland dominated by Festuca ovina where tall grass Calamagrostis epigejos was aggressively expanding. In contrast to grassland, stand utilized more due higher microbial demands for soil mineral N, which could prevent losses. Additional supply resulted increased mainly expanding...
Biochar can increase the microbial activity of a soil and seed yield oilseed rape. We performed field experiment to determine effect different doses biochar impact nutrient additions on in soils with low pH (4.69). Different were applied plots 2016 (0 t/ha (control), 15 (B15), 30 (B30), or 45 (B45)), fertilization was during 2019 (90 kg P/ha) 2020 (50 N/ha, 80 P/ha, 50 K/ha). Maize grown 2016, barley 2017, maize 2018, wheat 2019, winter rape 2020. All analyses carried out Higher led reduced...
Global climate change is predicted to alter growing season rainfall patterns, potentially reducing total amounts of precipitation and redistributing into fewer but larger individual events. Such changes may affect numerous soil, plant, ecosystem properties in grasslands ultimately impact their productivity biological diversity. A five-year field study with regulated amount was executed different types temperate (dry Festuca, wet Cirsium Nardus grasslands) three regions (in lowland, highland...
Abstract The production of gastro-waste is an common issue part in all societies, but its disposal, including recycling, not yet satisfactorily resolved. This research explored whether it possible to manage this waste directly at source without special equipment and high initial investments. study was conducted on a university campus, where simple three-tier vermicomposter assembled process cafeteria leftovers. vermicomposting the quality resulting vermicompost were monitored, container...
Biochar (BCH) is one of the most promising amendments to improve soil quality and store carbon in soils. Vast majority studies utilized freshly produced materials assess BCH effects immediately after amendment. The aim this study was investigate influence biochars aged six months with two types on physicochemical biological properties along plant growth. Soils from a protection zone water sources an agricultural area were mixed three different BCH. After aging, lettuce (Lactuca sativa var....
Objective. Dehydrogenase activity after the biological activation of biochar by native soil microorganisms was studied. The main aim to improve properties and make it more friendly for microflora. Materials methods. reached aerating with solution two weeks. No special inoculum applied. following treatments in four replicates were prepared: conventional raw (BR), activated (BA), mineral fertilizer DAM 390 (NF), control (C). A statistical test comparing means (Fisher p≤0.05; program STATISTICA...
