Dr. Dimkpa’s research within the Department of Analytical Chemistry focuses on the fate and effects of engineered nanomaterials in agricultural plants, and the use of nanoscale nutrients to suppress crop diseases. One of the main themes of our research is on designing ways to minimize agrochemical inputs without sacrificing yield through the use of nanoscale nutrients. For instance, work on phosphorus (P) that is synergistic to the current USDA project involves formulation of P forms with biopolymers such as chitosan and/or the incorporation of micronutrients to regulate P availability to plants as described below.

My research is focused on the release, fate, effects and remediation of contaminants in the environment. I have worked with the whole spectrum of substances that are released as a result of human activities including pesticides, polymers, PAHs, PFASs, pharmaceuticals, metals and nanoparticles. Projects can involve desk-based, laboratory and field experiments, and aim at generating solid scientific bases to improve the management of our environment. I am particularly interested in elucidating the processes occurring at solid interfaces (e.g. sorption, degradation, uptake by organisms), and understand how they are influenced by environmental factors and the contaminant properties. My recent research on the ecological risk assessment of nanopesticides is a good illustration of the multidisciplinary approach applied in my group over the last years.

Food-Energy-Waste-Sustainability Program (FEWS) Center for Sustainable Development, Qatar University
The Food-Energy-Waste-Sustainability (FEWS) Program that is constituted of the respective research topics and operates under the auspice of the Center for Sustainable Development (CSD), Qatar University aims at holistically dealing with the technology development and the main environmental issues of Qatar in a sustainable manner, being completely in line with the Qatar's national vision (QNV2030). Currently, the food production sector in Qatar faces major challenges related mainly to adverse pedo-climatic conditions, high production costs, and the generation of huge amounts of wastes. Under the current conjuncture, any increase in food production will inevitably deepen the unsustainable management of the available resources and will negatively affect the future development of Qatar’s economy. In this regard, the multidisciplinary team of the FEWS program proposes advanced technological solutions to increase food production in Qatar while preserving the limited/non-renewable resources and the environment. For instance, the use of adapted crop species, treated wastewater, non-conventional agricultural inputs, and novel technologies could decrease production costs in Qatar while ensuring a stable food and feed supply to the local market. In this regard, recycling abundant organic and inorganic wastes could help providing sustainable sources of nutrients to crops and synthetic materials for production systems, which will also reduce risks of environmental contamination due to waste landfilling. Furthermore, smart greenhouses powered microgrid may be considered as a key solution to introduce new technologies in agriculture taking advantages of renewable energy, advances in monitoring techniques, artificial intelligence, meeting and communication infrastructure. This may drive comprehensive transition to precision activities creating environmental and socio-economic benefits, although assuring the high-performance capacities, fostering thus the modernization of the agricultural sector. Hence, the FEWS program will enlist the application of various interdisciplinary scientific approaches for preserving the country’s natural environment, following a sustainable way, a “cradle-to-cradle” and a “closing the loop” reasoning in the agricultural, renewable energy and waste management sectors.  

  

 

USDA Grant: Project Summary

 

PD- Jason C. White, The Connecticut Agricultural Experiment Station (CAES); Co-PD- David Howard Fairbrother, Johns Hopkins University (JHU); Co-PD- Wade Elmer, CAES

     This is a Food and Agriculture Science Enhancement (FASE) Strengthening Standard Grant submitted to the USDA AFRI Foundational Program’s Agriculture Systems and Technology Program Area; Priority Code A1511 “Nanotechnology for Agricultural and Food Systems”

     By 2050, the global population will exceed 9 billion, making maintaining global food security one of the most significant challenges we face as a species. Food production will need to increase by 70% but importantly, year-over-year-yield increases for many crops have been declining. Additionally, the lack of sustainability of current agriculture will confound maintaining global food security. For example, the low efficiency of nutrient delivery (10-20%) is a significant constraint, wasting energy and water resources, and causing environmental damage as growers “over-apply” to adequately feed crops. Consequently, there has been great interest in nano-enabled approaches to increase both the efficiency and targeting of nutrient delivery in agriculture.

     Phosphorus use will exceed 26, 000 Gg/year by 2050, although delivery efficiency is typically only 10-15%. In addition to being unsustainable, the excessive use of P is a threat to aquatic environments and human health. We have preliminary data demonstrating that a biodegradable polymer-nanoparticle composite containing phosphate nanoparticles promotes plant growth as effectively as traditional fertilizers while reducing P run off by 10-fold. Building on this, we will develop a suite of P-containing biodegradable polymer nanocomposites able to deliver nutritionally required amounts of P to different crops in a spatially and temporally precise fashion. Moreover, this P delivery will be achieved with significantly reduced input amounts and with dramatic reductions in environmentally damaging P run-off/leachate. The long-term goal of this project is to develop a safe and sustainable biopolymer-based nanofertilizer platform for macronutrient delivery in both field and urban agriculture scenarios. Our three objectives are:

Obj.1- Identify biodegradation rates and P leaching/retention characteristics of different P-containing biodegradable nanocomposites in different soils. This information will enable us test our hypothesis that P release rates are directly correlated with and controlled by polymer biodegradation and that this mechanistic relationship allows material tunability.

Obj.2- Determine the viability of P-containing biodegradable polymer nanocomposites to enhance growth of different crops while minimizing P run off in greenhouse-based plant studies. 

Obj.3- Validate P-containing biodegradable polymer nanocomposite performance for a range of different crops at field scale.

     Our approach will be to develop a suite of P-containing biodegradable polymer nanocomposites that release P at tunable rates in response to polymer biodegradation. Once material properties have been optimized, greenhouse and field trials will be conducted with crops of varying nutritional demands (lettuce, tomato, soybean, corn, wheat) to demonstrate tunable efficacy across species and soil conditions, as well as across multiple planting cycles.  Although NP use in agriculture is increasing, delivery strategies that are precise and accurate both spatially and temporally remain elusive.  Novel and tunable P delivery approaches such as those developed in this work have great potential to significantly improve nutrient utilization and facilitate efforts to maintain global food security. To support this work, we will establish a Center of Excellence that will deploy a unique combination of educational and dissemination strategies to engage a range of stakeholders in this project.

 

Nanotechnology has great opportunities to improve plant agriculture. Nanopesticides might have a higher efficacy and help to prevent runoff to surface and ground water. Nanotechnology-based genetic engineering might offer tremendous advantages compared to classical techniques. Plants could be used as sensors to provide information about their nutritional or health status. Nanotechnology might be used to modify the soil microbiome or be used in soil conditioning, and nano-carrier bound fertilizers might be more efficient than conventional products. Nano-enabled coatings might improve seed quality"(Hoffman et al. 2020. Moving forward responsibly in nanotechnology enabled plant agriculture. Nature Food, 1, 416–425).

Technology readiness level (TRL) for proposed application areas or approaches for nano-enabled technologies that can benefit agriculture. The TRL was determined based on available data regarding the maturity of the technology including the scale at which the materials or approach has been applied, and the number of studies that provide evidence of efficacy, and the number of commercially available products. The technology performance level (TPL) was determined based on expert judgment regarding the potential magnitude of the impacts that each technology may potentially provide to improve the sustainability of agriculture. (Hoffman et al. 2020.
