Special Issue Information

Dear Colleagues,

Conservation agriculture (CA) relies on three fundamental pillars: diversified crop rotation, permanent soil cover, and no soil disturbance (i.e., only the soil disturbance by the seeder is tolerated). In CA, there are fewer weed control possibilities because pre-sowing tillage and in-crop mechanical weeding are not possible. This may impact the weed community’s taxonomic or functional composition and thus weeding tactics over time. Despite all the ecosystem services provided by CA systems, weed/crop volunteer management as well as cover crop termination mainly rely on the use of herbicides such as glyphosate, worldwide.

This Special Issue will focus on “Conservation Agriculture and Agroecological Weed Management”. We welcome new research, reviews, and opinion articles covering all related topics, including the relative role of the three pillars on weed management, biodiversity-based weed management in CA, new practices to limit weed establishment or spread, weed dynamics over time, functional approaches, weed–crop competition, seedbank, interactions between weeds and others organisms, successful experiences in designing and testing pesticide-free CA systems, and the role of livestock in CA systems to manage weeds.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Recently adopted in France, conservation agriculture still faces some challenges to its adoption, particularly weed management. To highlight the weed management practices used by farmers in conservation agriculture and the changes induced by its adoption, a large sample of 425 French farmers were invited to complete an online survey. Weed management practices used by farmers were requested for three periods: before adoption, during the first years of conservation agriculture (one to two years after adoption), and when the agricultural system is considered “mastered” by the farmer. The use of each farming practice was firstly studied independently for each period. Then, a multiple correspondence analysis followed by a hierarchical ascendant classification resulted in groups of farmers with different combinations of practices for each period. Finally, the groups of farmers were followed through the periods. Results showed that changes in weed management done according to farmers when adopting and mastering conservation agriculture are multiple and vary according to farmers and their previous weed management. Although some similar choices were identified, some farmers’ trajectories, especially those with a prior combination driven by either a soil disturbance strategy or a crop competitiveness strategy, are difficult to identify when adopting conservation agriculture. Upon mastering the agricultural system, farmers’ choices become more apparent. Full article
