“…These fertilizers are comprised of plant nutrients in an encapsulated form that delays availability for plant uptake, therefore extending the window in which the fertilizer is available for use after a single application (Fu et al, 2018). The use of CRS encapsulated fertilizers has many potential benefits, including delivery of nutrients to crops, maintaining water availability, and reducing greenhouse gas emissions by limiting the availability of applied nitrogen for denitrification and N 2 O production (Jariwala et al, 2022). In addition, by controlling fertilizer release into soil, CRS encapsulated fertilizers can prevent shifts in soil pH, as overfertilization leads to acidification (Jariwala et al, 2022).…”

“…Controlled release fertilizers like Osmocote operate by limiting access to water to limit encapsulant solubilization or through slow coating hydrolysis to limit release over time. Coating fertilizers with multiple materials, including CRSs, is a growing area (Jariwala et al, 2022;marketresearch, 2022a); and the industrial leaders in this area are BASF Corporation, DuPont Pioneer, and Invista. New products in this market include U-COAT (Bio-on), a controlled release coating of urea fertilizer produced using proprietary bioplastic.…”

“…CRSs may be degraded before they reach their targets because of changes in soil physical or chemical conditions (e.g., local acidification). To date, most CRSs applied in agriculture have utilized either passive release or smart release controlled by environmental properties (i.e., temperature, pH, and soil moisture) (Jariwala et al, 2022). The latter approach demands environmental stability for constant and uniform release.…”

Sustainable food production is a grand challenge facing the global economy. Traditional agricultural practice requires numerous interventions, such as application of nutrients and pesticides, of which only a fraction are utilized by the target crop plants. Controlled release systems (CRSs) designed for agriculture could improve targeting of agrochemicals, reducing costs and improving environmental sustainability. CRSs have been extensively used in biomedical applications to generate spatiotemporal release patterns of targeted compounds. Such systems protect encapsulant molecules from the external environment and off-target uptake, increasing their biodistribution and pharmacokinetic profiles. Advanced ‘smart’ release designs enable on-demand release in response to environmental cues, and theranostic systems combine sensing and release for real-time monitoring of therapeutic interventions. This review examines the history of biomedical CRSs, highlighting opportunities to translate biomedical designs to agricultural applications. Common encapsulants and targets of agricultural CRSs are discussed, as well as additional demands of these systems, such as need for high volume, low cost, environmentally friendly materials and manufacturing processes. Existing agricultural CRSs are reviewed, and opportunities in emerging systems, such as nanoparticle, ‘smart’ release, and theranostic formulations are highlighted. This review is designed to provide a guide to researchers in the biomedical controlled release field for translating their knowledge to agricultural applications, and to provide a brief introduction of biomedical CRSs to experts in soil ecology, microbiology, horticulture, and crop sciences.

“…The quick release of urea can cause severe damage to crops and the environment by nitrate loss in groundwater and ammonia volatilization (Azeem et al, 2014). Recently, growers are moving toward climate-smart agricultural practices and have started using coated/slow release/controlled release fertilizers for the nitrogen source (Jariwala et al, 2022). The plant also requires micronutrients, and among all micronutrients, silicon is considered a non-essential plant micronutrient (Epstein and Bloom, 2005).…”

Mineral–Soil–Plant–Nutrient Synergisms of Enhanced Weathering for Agriculture: Short-Term Investigations Using Fast-Weathering Wollastonite Skarn

Enhanced weathering is a proposed carbon dioxide removal (CDR) strategy to accelerate natural carbon sequestration in soils via the amendment of silicate rocks to agricultural soils. Among the suitable silicates (such as basalt and olivine), the fast-weathering mineral wollastonite (CaSiO3) stands out. Not only does the use of wollastonite lead to rapid pedogenic carbonate formation in soils, it can be readily detected for verification of carbon sequestration, but its weathering within weeks to months influences soil chemistry and plant growth within the same crop cycle of its application. This enables a variety of short-term experimental agronomic studies to be conducted to demonstrate in an accelerated manner what could take years to be observed with more abundant but slower weathering silicates. This study presents the results of three studies that were conducted to investigate three distinct aspects of wollastonite skarn weathering in soils in the context of both agricultural and horticultural plants. The first study investigated the effect of a wide range of wollastonite skarn dosages in soil (1.5–10 wt.%) on the growth of green beans. The second study provides insights on the role of silicon (Si) release during silicate weathering on plant growth (soybeans and lettuce). The third study investigated the effect of wollastonite skarn on the growth of spring rye when added to soil alongside a nitrogen-based coated fertilizer. The results of these three studies provide further evidence that amending soil with crushed silicate rocks leads to climate-smart farming, resulting in inorganic carbon sequestration, as well as better plant growth in agricultural (soybean and spring rye) and horticultural (green bean and lettuce) crops. They also demonstrate the value of working with wollastonite skarn as a fast-weathering silicate rock to accelerate our understanding of the mineral–soil–plant–nutrient synergism of enhanced weathering.
