The effect of Scots pine admixture in European beech stand on the leaching of dissolved organic carbon (DOC), dissolved organic nitrogen (DON), nitrate nitrogen (NO3-N) and ammonium nitrogen (NH4-N) f...
Nineteen new strawberry breeding clones, bred at the Institute for Breeding Research on Fruit Crops in Dresden-Pillnitz, Germany, were evaluated for their suitability for organic production at a Verti...
Tree growth, flowering, yield and fruit quality of Prunus armeniaca L. cv. Ninfa grafted on peach cv. Nemaguard [Prunus persica (L.) Batsch] and cv. Real Fino apricot (Prunus armeniaca L.) as rootstoc...
Leek is a weak competitor against weeds. A field experiment was conducted to determine the effects of herbicides and mulching on weed flora, growth and yield of a leek crop. A randomized complete bloc...
The aim of this study was to establish protocol for in vitro regeneration and multiplication of Cymbidium pendulum through protocorms, as explants using organic growth supplements such as banana homog...
The study deals with the monitoring of dissolved organic carbon (DOC) concentrations in seepage water sampled from differently managed forest plots in the Drahansk?vrchovina Upland. Simultaneously, th...
The present study concentrated on the development of an analytical method for determination of emissions of volatile organic compounds from crude and heat treated amaranth (genus Amaranthus L.) sample...
The individual adsorption/desorption of Cu, Pb, and Zn in six soil samples taken from organic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of t...
Epidemiological studies comparing risk factors for subclinical mastitis (SM) in organic (OP) and conventional dairy production systems (CP) are lacking. In 60 OP and 60 CP farms, 970 cows were used to...
A pot experiment was conducted to study interactive effects of arbuscular mycorrhizae (AMs) and maize (Zea mays L.) straws on wheat (Triticum aestivum L.) growth and organic carbon (C) storage in a st...
Forests occupy one third of the world’s land area and govern carbon (C) transfers and influence nitrogen (N) content in the biosphere. Afforestation leads to soil changes of specific dynamics, often a...
The antimicrobial activity of fatty acids, monolaurin, citric, succinic, fumaric, malic and lactic acid was determined in cultures of two strains of Escherichia coli, three strains of Salmonella sp. a...
The effect of erosion and erosion control measures on changes in the amount of organic matter in soil was studied. We investigated the influence of organic matter inputs into the soil on surface runof...
One of the key goals of the Thematic Strategy for Soil Protection is to maintain and improve soil organic carbon (SOC) stocks. A decline of SOC stocks is politically perceived as a serious threat to s...
In 2008 and 2009 the effects of quassin and neoquassin (oxygenated triterpenes) on apple sawfly (Hoplocampa testudinea Klug, 1814) were studied. In the Czech Republic, monitoring was carried out in sm...
