Research Interests

My research focus has been on understanding the effects of agricultural practices (APs) such as soil amendments, tillage and cropping systems on plant-nematode-soil-nutrient interactions at the organism and ecosystem levels with special emphasis on developing models that identify integrated and sustainable nematode, nutrient cycling, and soil health management strategies. Soil health has biological, physicochemical, nutritional, structural and water-holding components that need to be kept in balance. Sustainable soil health requires i) generating three sets of ecosystem services: a) improve soil structure, physicochemistry, nutrient cycling and water holding capacity; b) suppress pests and diseases while increasing beneficial organisms in the same environment; and c) improve biological functioning and crop yield; and meeting ii) environmental and iii) economic expectations simultaneously. My program uses three nematode community analyses-based models as decision-making tools in translating basic and applied multi-disciplinary soil health knowledge into sustainable and practical applications.

Nematodes, the most abundant metazoan on the planet, include beneficial (bacterivores, fungivores, predators and omnivores) and harmful (herbivores) trophic groups (TGs). Within TGs, there are five colonizer-persistor (c-p) categories ranging from fast- (c-p 1) to slow-reproducing (c-p 5) groups. Herbivore nematodes cause crop quality and yield loss by either partially- (ectoparasites) or fully-embedded (endoparasites) in plant tissues and sucking host cell contents and disrupting water and nutrient uptake and the photosynthesis process in one of three ways: destructive (host cells killed, e.g. root-lesion, Pratylenchus), adaptive (cells modified e.g. cyst, Heterodera) and neoplastic (cells modified and undergo new growth, e.g. root-knot, Meloidogyne) feeding behaviors. Beneficial nematodes are central players in the soil food web (SFW), nutrient cycling and important indicators soil health conditions. We developed a Fertilizer Use Efficiency (FUE) model by measuring the relationship between changes in the abundance of either beneficial or harmful nematodes quantified at the trophic group level and ecosystem services (e.g. soil organic matter, nutrient, yield, etc.) to identify best-to-worst case soil health outcomes for sustainability and meeting economic and environmental expectations (see fig. 5: https://doi.org/10.3390/soilsystems5020032). In addition to separating the role of beneficial and harmful nematodes in the same environment, the FUE model enables decision-making without accounting for the nematode functions or the biophysicochemical processes driving the SFW.

We use the Ferris et al. (2001) SFW model to understand the biophysicochemical process-based soil health outcomes. This model quantifies beneficial nematodes at the TG and c-p group levels and relates changes in population dynamics relative to food and reproduction (Enrichment Index) and tolerance to disturbance (Structure Index) and identifies if an AP is resulting in best-to-worst outcomes for nutrient cycling and agroecosystem suitability (see fig 3: https://doi.org/10.3390/soilsystems5020032). Our third and most recent decision-making tool is the lntegrated Productivity Efficiency (IPE) model. The IPE model quantifies beneficial nematodes at the TG and c-p levels and uses similar principles as the FUE model to separate outcomes into sustainable, unsustainable, or requiring specific modification to be sustainable categories for soil health indicator, nematodes and soil health (see fig. 2: https://doi.org/10.3390/soilsystems6020035). The three models are decision-making tools that provide foundations towards step-by-step integration and alignment of different ecosystem services and soil health indicators and developing sustainable soil health management strategies on the basis of one-size-fits-all or a location-specific approaches.

Extension and Outreach Interests

Working with MSU Extension Educators, my goal is to increase awareness towards achieving sustainable soil health management strategies in cropping systems by translating complex biophysicochemical-driven information in ways that relate to production.
