A new concept for the control of Elytrigia repens in organic crop production [PDF]
, 2012 The control of perennial weeds in organic crop production needs reconsideration to minimise losses of nutrients through leaching. Long post-harvest periods with mechanical weed control hinder a plant cover with the purpose of taking up nutrients not ...

Analysis and Definition of the close-to-crop Area in Relation to Robotic Weeding [PDF]
, 2004 The objective of this paper is to analyse and define the field conditions close to the crop plants of sugar beet (Beta vulgaris L.). The aim is to use this study for the choice and development of new physical weeding methods to target weeds at individual

Cover crops in cool‐climate viticulture: Effects on soil, vine productivity, and fruit quality
Agronomy Journal, Volume 117, Issue 5, September/October 2025.Abstract Cool temperatures, higher rainfall, and suitable grape (Vitis vinifera L.) varieties of cool‐climate vineyards make them distinct from more traditional wine‐growing regions. This review summarizes 33 published experiments on the use of cover crops in cool‐climate vineyards from 1999 to 2024.

Heavy metal contamination of spontaneous vegetation and soil around the copper smelter "Legnica"
Acta Societatis Botanicorum Poloniae, 2014 The area around the copper smelter "Legnica" in western Poland is influenced by pollutants from the smelter for about 35 years. Ecosystems within a distance of 1-2 km from the smelting complex are heavily degradated.

Functional coexistence theory: Identifying mechanisms linking biodiversity and ecosystem function
Ecological Monographs, Volume 95, Issue 3, August 2025.Abstract Theory and experiments show that diverse ecosystems often have higher levels of function (for instance, biomass production), yet it remains challenging to identify the biological mechanisms responsible. We synthesize developments in coexistence theory into a general theoretical framework linking community coexistence to ecosystem function. Our

A modified stairstep apparatus for studies of allelopathy and other phytotoxic effects
Agricultural and Food Science, 1984 The characteristics and performance of a modified stairstep, nutrient solution recycling, apparatus are described. An experiment in which the allelopathic potential of Agropyron repens was examined showed the apparatus to be reliable and accurate in ...
