Bioeffectors for a sustainable intensification of Agriculture

This article collection has been initiated as an outcome of a satellite session at the "Rhizosphere 4“ conference, held in Maastricht, the Netherlands from 21-25 June 2015. The majority of the manuscripts originate from contributions presented at the conference, promoting the research activities of the integrated EC Project BIOFECTOR, located within the European Union’s 7th Framework Programme (Grant Agreement n°312117), with the aim to investigate perspectives to use bioeffectors of microbial and non-microbial origin to optimise the efficiency of fertilisation systems as more sustainable alternatives to conventional mineral fertilisation. The topic addresses promising approaches but also limitations and future research needs of the investigated strategies.

  1. Research

    The effect of Penicillium bilaii on wheat growth and phosphorus uptake as affected by soil pH, soil P and application of sewage sludge

    Penicillium bilaii may enhance P availability to plants, since it has been shown to increase plant growth and P uptake. There is currently increasing interest in using microorganisms t...

    Micronutrients (Zn/Mn), seaweed extracts, and plant growth-promoting bacteria as cold-stress protectants in maize

    Low soil temperature in spring is a major constraint for cultivation of tropical crops in temperate climates, associated with impaired seedling development, inhibition of root growth and root activity. In this...

    Improving fertilizer-depot exploitation and maize growth by inoculation with plant growth-promoting bacteria: from lab to field

    Among other responses, plants tend to increase root growth to scavenge nutrients from more soil when soil nutrient concentrations are low. Placement of fertilizers near seeds or roots facilitates nutrient acqu...

    Phytochemical profiling of tomato roots following treatments with different microbial inoculants as revealed by IT-TOF mass spectrometry

    In light of the growing interest for eco-compatible fertilization, tomato plant roots were treated with four different strains of microorganisms (B1–B4) capable of positively affecting plant growth. The methan...
