Soil water retention (SWR) is an important soil property related to structure, texture, and organic matter (SOM), among other properties. Agricultural management practices affect some of these properties in interdependent way. In this study, the impact management-induced changes carbon (SOC) on SWR evaluated five long-term experiments Europe (running from 8 up 54 years when samples were taken). Topsoil (0–15 cm) collected analysed evaluate effects three different categories, i.e., tillage,...
The climate changes and increased drought frequency still more frequent in recent periods bring challenges to management with wheat straw remaining the field after harvest its decomposition. experiment carried out 2017–2019 Czech Republic aimed evaluate winter decomposition under different organic mineral nitrogen fertilizing (urea, pig slurry digestate without inhibitors of nitrification (IN)). Treatment Straw 1 fertilizers was incorporated soil each year first day experiment. 2 placed on...
The effect of organic, mineral and combined organic fertilization soils on the winter wheat yields nutrient contents in was evaluated long-term field experiments. Two sites with different soil characteristics were - Lukavec u Pacova (cambisol) Ivanovice na Hané (degraded chernozem). type influenced yields. Nutrient uptake by higher under nitrogen (N) fertilization, which resulted a negative balance phosphorus (P) potassium (K) to decrease more fertile at Hané. tests (Mehlich 3 method...
CO2 emissions are one of the greenhouse gases that significantly contribute to climate change. The use reduced soil tillage practices could mitigation from soils under ongoing change conditions. and no-tillage in summer period, most critical period for water loss soils, would is required by European Union. aim this research was specification emission factors, following different variations weather. Gentler were defined terms reducing soil. This carried out as a long-term field experiment....
The field experiment with different soil tillage treatments has been carried out in Prague-Ruzyně locality (Czech Republic) since 1995. Data of two growing cycles the years 2007-2010 and 2011-2014 were evaluated. Tillage technique was decisive for changes characteristics crop yields. Bulk density, organic carbon (Corg) microbial biomass C (Cmic) more equilibrated throughout all tested layers (0-0.1; 0.1-0.2 0.2-0.3 m) conventional (CT). In reduced (RT) no-tillage (NT) significant...
CO2 emissions represent one of the greenhouse gases significantly affecting climate change. Reduced tillage practices can contribute to mitigation from soils. The effect with different straw incorporation on was studied in field experiments years 2020 and 2021. winter wheat used 2020, spring barley Treatments were: (1) chiselling 10–12 cm; (2) shallow (5–6 cm depth); (3) mulch, (4) stubble. warm summer period increased soils even twice comparison other soil practices. temperature decreased...
The content of nitrate or mineral nitrogen (Nmin = N-NO-3 + N-NH +4) in soil autumn is recognized as the indicator potential risk N leaching during winter. In this contribution, apparent changes Nmin 0-60 cm layer, winter, on farm fields Czech Republic were calculated. A significant positive relationship between and change winter was observed eight out nine farms. Nitrate data produced similar relationships Nmin. regression analysis suggested that 40-90% above a specific amount, 14-35 kg...
The boron (B) availability in soils, B uptake and possible interactions with phosphorus (P) were studied a pot experiment increasing P rates. Three soil types of different characteristics used for the that lasted two years. tests - Mehlich 3 NH4-acetate. Significant positive correlations found between barley dry matter yield, content plants under treatments (P ≤ 0.001). significant relationship 0.001) was obtained all tested soils. A decrease soils doses determined. NH4-acetate test showed...
The impact of precipitations and air temperatures on winter wheat yields was evaluated in a 34-year long- term field trial with mineral organic fertilization established at two experimental sites different soil-climatic conditions: Ivanovice na Hané well fertile soils (degraded Chernozem), higher average year lower precipitations; Lukavec situated Bohemian-Moravian highlands less (Cambisol), precipitations. At both sites, significant positive effect used fertilizers noted from the dose 80 kg...
Abstract. Inversion tillage is a commonly applied soil cultivation practice in Europe, which often has been blamed for deteriorating topsoil stability and organic carbon (OC) content. In this study, the potential to reverse these negative effects by alternative agricultural management practices are evaluated seven long-term experiments (running from 8 54 years moment of sampling) five European countries (Belgium, Czech Republic, Hungary, Italy UK). Topsoil samples (0–15 cm) were collected...
Conservation tillage practices are increasingly used in agricultural systems. However, these require a complex approach regarding soil nutrition. Adequate nutrient content soils is important for crop production, as reduced and no-tillage change the distribution of contents (P, K, Mg, Ca) profile, necessitating new approaches agronomists Little known about time changes profile under conservation practices. Long-term field experiments with conventional (CT—plowing to 20–22 cm), (RT—chiseling...
Abstract. Inversion tillage is a commonly applied soil cultivation practice in Europe, which though has been blamed for deteriorating topsoil stability and organic carbon (OC) content. In this study, the potential to reverse these negative effects by alternative agricultural management practices are evaluated five long-term experiments (running from 8 54 years moment of sampling) Europe. Topsoil samples (0–15 cm) were collected analysed evaluate conservation (reduced no-tillage) or increased...
Surface runoff and soil losses in the case of potato cultivation using de-stoning technology on gentle slopes (Haplic Cambisol) were studied 2020–2022. Different ridges shapes compared: control (smooth shaped ridges), pits, pits plus loosening, loosening cover crop (Triticum aestivum L.) sowing trail furrows. Runoff approximately 1 2 months after planting potatoes. The obtained results showed highest reduction surface treatment with sowing. In this variant, reduced by 65–81% (1 month...
