Cover cropping has emerged as a sustainable alternative to traditional crop rotational practices, yet the effects of variable root exudation from cover crop species and cultivars within species remains unclear. Here, we assess the chemical heterogeneity of root exudates from 16 commonly used cover crop species as well as 3 distinct cultivars of hairy vetch. Plants were grown hydroponically and analyzed via nontargeted gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS), and targeted LC-MS/MS to evaluate patterns in root exudate composition across species and functional plant type. Overall, root exudation profiles are heterogeneous across crop species and cultivars. Species within legumes stand out as a unique functional group of plants capable of producing distinct chemical environments rich with complex secondary metabolites, such as triterpenoid saponins (soyasaponins), isoflavonoids, and flavonoids.

This study explores the potential use of mould biomass and waste fibres for the production of agrotextiles. First, 20 mould strains were screened for efficient mycelium growth, with optimized conditions of temperature, sources of carbon and nitrogen in the medium, and type of culture (submerged or surface). A method was developed for creating a biocomposite based on the mould mycelium, reinforced with commercial bleached softwood kraft (BSK) pulp and fibre additives (cotton, hemp).

Agricultural soil environments contain different types of nematodes in all trophic levels that aid in balancing the soil food web. Beneficial free-living nematodes (FLNs) consist of bacterivores, fungivores, predators, and omnivores that help in the mineralization of the soil and the top-down control of harmful plant-parasitic nematodes (PPNs). Annually, USD 125 billion in worldwide crop losses are caused by PPNs, making them a plant pathogen of great concern for growers.

Managing dairy excreta as slurry can result in significant emissions of ammonia (NH) and greenhouse gases (GHGs) during storage and thereafter. Additionally, slurry often has an imbalanced nitrogen (N) to phosphorus (P) ratio for crop fertilization. While various treatments exist to address emissions and nutrient imbalances, each has trade-offs that can result in pollution swapping.
