Phosphorus (P) is a limiting nutrient in many agroecosystems and costly fertilizer inputs can cause negative environmental impacts. Cover crops constitute promising management option for sustainable intensification of agriculture. However, their interactions with the soil microbial community, which key driver P cycling, effects on following crop, have not yet been systematically assessed. We conducted meta-analysis published field studies cover focusing plant-microbe interactions. describe...
Abstract Data about gene escape by seeds and volunteers were compiled for the first time in one study several crops, i.e. wheat ( Triticum aestivum ), sugar beet Beta vulgaris oilseed rape/canola Brassica napus ) maize Zea mays ). These species represent important genetically modified (GM) crops with herbicide tolerance (HT) or insect resistance (Bt), show different levels of autogamy allogamy are grown climatic zones world. Post-harvest measures strategies identified minimizing from these...
Abstract Aims An essential task of agricultural systems is to improve internal phosphorus (P) recycling. Cover crops and tillage reduction can increase sustainability, but it not known whether stimulation the soil microbial community availability organic P pools. Methods In a field experiment in southwest Germany, effects winter cover crop mixture (vs. bare fallow) no-till non-inversion tillage) on P-cycling were assessed with soybean as main crop. Microbial biomass, phospholipid fatty acids...
The present paper reports on three sets of experiments exploring the persistence seeds oilseed rape ( Brassica napus ). first, where known numbers were buried in September 1991 two field experiments, demonstrated substantial initial losses seeds, such that only 0·2 and 3·8% still after 4 months. In these which not disturbed by mechanical cultivation, there was little evidence further decline over following 13 second then left undisturbed for a 136 A mean 1·8% this period, providing...
Laboratory studies on the biology of oilseed rape ( Brassica napus L.) showed that induction secondary dormancy is influenced by light environment, time exposure to and darkness, temperature regime genotype. Seeds did not become dormant while exposed but were increasingly likely longer they water stress darkness. Dormancy was broken alternating warm cold temperatures. Conclusions from results obtained in Petri dishes have been tested field hypotheses regarding effects post-harvest...
Mineral nitrogen (N) fertilization in cereals is commonly split into three or four applications. In order to simplify N fertilization, a single application either broadcast placed on the soil surface was compared conventionally for winter wheat (Triticum aestivum L.). The 4-year experiment (2007-2010) performed using participatory approach farmers' fields deep loamy soils (Luvisols) South-West Germany. Grain yield and crude protein contents differed only slightly not at all between...
Seeds of oilseed rape ( Brassica napus L.) can persist in the soil over several years by becoming secondarily dormant and then germinate to create volunteer plants following crops. As well as agricultural impacts caused volunteers, gene dispersal time – particularly from genetically modified cultivars be another undesirable consequence. Conventionally bred transgenic seeds were tested 2001 2002 laboratory experiments, a field experiment, burying determine variation dormancy persistence...

Summary In practical farming, early and shallow stubble tillage is carried out post‐harvest to stimulate germination of freshly ripened crop weed seeds, kill the resulting seedlings hence reduce input into soil seedbank. Additionally, it aims at reducing perennial weeds by mechanical damage. this paper, field experiments laboratory studies are presented which show that can weeds. However, had a variable effect on annual After 5 years experimentation, no was seen aboveground vegetation....
Maize is grown on a large area in Germany and there growing concern society about negative environmental effects related to this. The objective of the study was test performance mixtures maize climbing beans as an alternative monocropped under different site management conditions. sowing density well time total dry matter (DM) yield bean DM contribution were investigated. Further, various mechanical chemical weed control methods tested resulting compared with that reference treatment (manual...
Summary Seeds of oilseed rape ( Brassica napus L., cv. Liglandor) were induced into secondary dormancy by imbibing them for 2‐4 weeks in an osmotic solution at ‐1500 kPa darkness. Treated seeds then transferred pots or Petri dishes, where they given adequate water germinatton. These and dishes exposed to various temperature regimes during the course following 6–14 months. During that time, seed samples taken 2‐ 6‐ weekly intervals monitor survival study their dormancy. The ntimber had not...
Summary The study examined the effect of tillage (intensive vs. zero tillage) on potential gene flow during life cycle oilseed rape volunteers between July 2002 and August 2003. After growing rape, 4–29% seeds lost harvest entered soil seedbank when stubble was performed immediately after seed input. small (0–3%) delayed. Zero resulted in seedbanks from 1 to 17% initial were distributed mainly upper layers or primary with a rigid tine cultivator, whereas ploughing shifted most into deeper...
