Abstracts |
Increased reliance on biological processes and root interactions with soil biota through ‘ecological intensification’ in agroecosystems generates environmental benefits and decreases reliance on fossil-fuel based fertilizers. Here we give some examples of recent progress in understanding how agricultural management affects soil microbial-root and microbial-rhizosphere processes and nitrogen cycling. These include processes within the root (arbuscular mycorrhizal symbiosis), in the rhizosphere (biological inhibition of nitrification), and with the soil organisms surrounding the root (soil food webs in cultivated vs. grassland ecology). More such information will lead to new management options and site-specific solutions to cycle and retain nitrogen in agroecosystems. |
