People and Nature, EarlyView.Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

RIMPhil: a bioeconomic model for integrated weed management of annual barnyardgrass (Echinochloa crus-galli) in Philippine rice farming systems [PDF]
This paper describes a complex, dynamic simulation model that has been developed for the analysis of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice farming systems in the Philippines.

Organic tree sector in the Netherlands [PDF]
, 2011 The Dutch organic tree sector is quite small. The main issues for this sector are extending the market share of organic tree nursery products and improving mechanical weed control.

People and Nature, EarlyView.Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Mechanical and chemical weeding effects on the weed structure in durum wheat
Italian Journal of Agronomy, 2020 A three-year field experiment was performed to study weed infestation of durum wheat at the stage of emergence and full maturity. Two weeding systems (WS) were used in the post-harvest period: i) mechanical weeding (MW); and ii) chemical weeding (CW). In the MW system, soil underwent shallow ploughing at a depth of 10-12 cm and double harrowing (after ...

Mechanisms of herbicide resistance in weeds
Korean Journal of Agricultural Science, 2017 In major field crops, synthetic herbicides have been used to control weeds worldwide. Globally, herbicide resistance in weeds should be minimized because it is a major limiting factor for food security. Cross resistance can occur with herbicides within the same or in different herbicide families and with the same or different sites of action.
