Noninversion tillage with tine- or disc-based cultivations prior to crop establishment is the most common way of reducing for arable cropping systems small grain cereals, oilseed rape, and maize in Europe. However, new regulations on pesticide use might hinder further expansion reduced-tillage systems. European agriculture asked become less dependent pesticides promote protection programs based integrated pest management (IPM) principles. Conventional noninversion rely entirely availability...
The search for approaches to a holistic sustainable agriculture requires the development of new cropping systems that provide additional ecosystem services beyond biomass supply food, feed, material, and energy use. reduction chemical synthetic plant protection products is key instrument protect vulnerable natural resources such as groundwater biodiversity. Together with an optimal use mineral fertilizer, agroecological practices, precision technologies, complete elimination in...
Abstract Negative impacts of pesticides on the environment and human health, risk pesticide residues in food chain, problems with herbicide‐resistant weed biotypes support need for alternative cropping systems. The objective this study was to investigate populations, management crop yield a pesticide‐free system use mineral fertilisers. Conventional‐, organic‐ mineral‐ecological systems (MECS) 6‐year rotations including winter wheat, maize, triticale or rye, soyabean spring pea, barley were...
A combination of static light scattering and video microscopy is used to perform high precision measurements on the growth velocity body centered cubic (bcc) crystals in a metastable colloidal melt monodisperse, highly charged latex spheres. The nucleate heterogeneously at walls flat flow-through shear cell solidification proceeds without significant disturbance by homogeneous nucleation. suspension parameters packing fraction \ensuremath{\Phi} spheres concentration screening electrolyte c...
Abstract By means of electroantennography and single cell recordings, GC GCMS analyses analysis with EAG detection (6E,11 Z)-6,11-hexadecadienal, Z)-6,11-hexadecadienyl acetate (4E,9Z)-4,9-tetradecadienyl were identified as the primary components sex pheromone female Antheraea pernyi (Lepidoptera: Saturniidae).
Abstract. Vor etwa 35 000-40 000 Jahren schuf eine Episode neotektonischer Aktivität an der Indus-Sutur bei Lamayuru (Ladakh) einen See, von dem über 105 m mächtige Abfolge fluviolakustriner Ablagerungen erhalten ist. Die zwischen Ton/Silt/Sand eingelagerten lakustrinen Horizonte (Kalkschlämme) und karbonatreichen Schichten haben Süßwasser-Ostrakoden, Gastropoden Charophyten geliefert. Insgesamt wurden 9 Fossilhorizonte angetroffen. hauptsächlichen Ostrakodentaxa sind llyocypris (l. gibba I....
Abstract Spatial distribution of soil mineral‐N content (N min ) is a scale‐variant process. Precision farming assumes knowledge about the spatial N . Moreover, sampling in management zones based on assumption dependence between points. In present study, variability structure and sources were investigated. Within an agricultural landscape, was investigated across field nested design over four consecutive years. Temporally unstable individual nests require with several field. field, 35%–49%...
Abstract Analysis of individual pheromone glands the false codling moth Cryptophlebia leucotreta Meyr. originating from South Africa, was performed by capillary gas chromatography. During calling period, pheromones are concentrated in dorsal part intersegmental membrane between abdominal segments V III and IX . The average amount related compounds present gland 412 ng/♀ This total highly variable to (200-740 ng/♀). However, relative amounts (Z)- (E)-8- dodecenyl acetates showed a narrow...
Application and sales of herbicides with glyphosate have strongly increased in Germany during the past 10 years. This has raised a number questions discussions concerning use. Therefore, this paper identifies evaluates alternatives an efficacy almost equivalent to for different treatmentareas terms economic consequences farms comparison use by way example. With help exemplary crop rotations uses arable farming winter wheat, oilseed rape, barley, maize summer barley were analyzed. Within...

Fur die Entwicklung der Verunkrautung sind viele Faktoren verantwortlich. Die direkte Unkrautbekampfung, meist durch Herbizide, spielt eine entscheidende Rolle. Aber auch weitere Faktoren, z. B. Fruchtfolge, uben einen erheblichen Einfluss auf aus. Ausgehend von Unkrauterhebungen zum Beginn Dauerversuche in Dahnsdorf wird langjahrige Veranderung gezeigt. Dabei werden zwei Betriebssysteme, Marktfrucht und Futterbau, vergleichend betrachtet. In beiden Betriebssystemen wurden unterschiedliche...
Abstract (E)-11-Hexadecenyl acetate is the major volatile component of sex pheromone gland female Leucinodis orbonalis collected from Sri Lanka. (E)-11-hexadecen-1-ol was also found in trace quantities.
Abstract Die größte Rolle für eine nachhaltige Entwicklung in der Bau‐ und Immobilienwirtschaft spielt Gebäudebestand. Das Immobilienmanagement trifft regelmäßig Entscheidungen, die einen großen Einfluss auf betreuten Objekte haben. Ökologische, ökonomische soziale Objektqualitäten sind Ausdruck Nachhaltigkeit können nur dann angemessen berücksichtigt werden, wenn Entscheider im Immobilien‐Asset‐Management (IAM) Property‐Management (PrM) ein konkretes Bild vom Ist‐Zustand ihrer Der Artikel...
