Biogeographical patterns of soil molecular microbial biomass
2011
Affiche - résumé. Session GC: Microbes in the Changing Environmenl: Global Climate Change and Soif under Human Impact; International audience; The spatial organization of soil microbial communities over large areas and the identification of environmental factors structuring their distribution have been liUle investigated. The overall objective of this study was to determine the spatial paUerning of microbial biomass in soils on wide extent and to rank the environmental fiUers most influencing this distribution, by using the French Soil Quality Monitoring Network. This network covers ail the French terrilory and soils were sampled at2,150 sites along a systematic grid sampling. The soil DNA …

Herbicide site specific spraying: use of simulations to study the impact of section width
2019
International audience; Site specific spraying is one way to reduce the amount of herbicide required to control weeds. The impact of boom section width was investigated by using simulated weed infestation maps with various weed coverage rates. Herbicide applications were simulated combining these virtual maps with various boom sections widths and various theoretical spray patterns. The objective was to quantify the herbicide reduction possibilities and potential under-application areas. Simulation derived results are analyzed using three indicators: i) the ratio between herbicide amount in the case of a targeted application and the amount deposited in the case of a full application, ii) the…

Stability of consumption pattern in two seed eating carabid species
2017
SPEGESTADDOCT INRA; Carabids can eat a substantial amount of seeds of weeds per day and are considered as credible biocontrol agents for the regulation of weeds in arable fields. Carabids species belong to either granivore, omnivore or carnivore trophic guilds and we expected each of these to have specific patterns of weed seed consumption and specific responses to biotic interactions. These differences will impact the total predation rate of a carabid community and may also explain why it is difficult to predict the efficiency of carabid biocontrol service. To test this expectation, we looked at the consumption pattern of two species of carabids species common in arable fields, one known a…
