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 the goal of developing integrated, sustainable and scalable nematode, nutrient cycling, and soil health management strategies. We use three nematode community analyses-based models that apply biological, mathematical and ecological principles to translate complex basic and applied multi-disciplinary soil health knowledge into practical application where suitable and sustainable soil health outcomes are identified.

A suitable soil health outcome is one that simultaneously generates three sets of desirable ecosystem services (DESs): 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. We have adopted the Ferris et al. (2001) Soil Food Web (SFW) model to identify suitable soil health outcomes. This model quantifies abundance and functions of beneficial nematodes 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).

A sustainable soil health outcome is characterized by generating i) the three sets of DESs (described above) while meeting ii) environmental and iii) economic expectations simultaneously. We use our novel Fertilizer Use Efficiency (FUE) model to identify soil health outcomes as sustainable, unsustainable or needing additional measures to be sustainable (see fig. 5 below). This model relates changes in the abundance of either beneficial or harmful nematodes separately and ecosystem services (e.g. soil organic matter, nutrients, yield, etc.). Nematodes are quantified at the trophic group level-just as most diagnostic labs do.

Our third and most recent lntegrated Productivity Efficiency (IPE) model applies the same principles as the FUE model on expanded beneficial nematode functions of the SFW model to separate outcomes into sustainable, unsustainable, or requiring specific modification(s) to be sustainable categories for soil health indicator (SHI), nematodes and soil health (see fig. 2: https://doi.org/10.3390/soilsystems6020035). SHI is the combined outcome of the changes in ecosystem services and nematode abundance and function.

Lack of integration models is a major limitation to achieving sustainable and scalable soil health management in production systems. A common thread the SFW, FUE and IPE models have is relating changes between and across parameters and drawing integrated decisions that cannot be achieved by considering individual parameters separately. These models can serve as integration platforms for step-by-step alignment of the three sets of DESs (described above) and developing sustainable soil health management strategies that can be scaled up across ecosystems and ecoregions on a one-size-fits-all or 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. Following are examples of publications:
