Soil biological quality in short- and long-term field trials with conventional and organic fertility input types [PDF]
, 2007 Soils of the DOK trial and three other field trials with manure input were analysed for effects on soil biology. While long-term effects indicate a new steady state at the DOK trial site, differences at the other field trials suggest that fresh manure at

Reactivity of an ortho‐Phenylene‐bridged Al/P Frustrated Lewis Pair Towards Small Molecules
European Journal of Inorganic Chemistry, Accepted Article.Frustrated Lewis Pairs (FLPs) as ambiphilic molecules are prone to activate small molecules and are in the focus of interest for many years. In this paper, we present the first ortho‐phenylene bridged Al/P‐based FLP with only one phosphine moiety. The title compound was employed in various reactions with small molecules featuring different functional ...

Duckweed: Growth factor and applications in nonfood, food, and health
Food Safety and Health, EarlyView.Versatile Duckweed! Duckweeds are aquatic plants that are mainly constituted of five genera, Lemna, Spirodela, Wolffia, Wolffiella, and Landoltia. The growth rates and chemical compositions are influenced by light intensity, photoperiod, nutrient content, microbial growth, temperature, medium salinity and conductivity, windspeed, climate, and water pH.
