“…These macronutrient fertilizers exacerbate the situation of farmers due to their inherent issues. In particular for the commonly used source of nitrogen (N), urea is subject to deprivation in the soil due to premature decomposition and volatilization . Hence, the proportion of urea efficiently absorbed by the plants is decreased, leading to a primary nutrient deficiency as N is needed for photosynthesis and all enzymatic reactions in a plant while improving the yield. , Most of the farmers apply extensive amounts of urea to overcome this issue, which has resulted in severe environmental pollution. ,− ,− , On the contrary, many agricultural soils are already oversaturated with plant nutrients due to the excessive application of fertilizers, leading to nutrient toxicity. , These issues as a whole demand that scientists explore other possible ways of efficiently delivering plant nutrients without being confined to conventional approaches.…”

Application of micronutrients through seed amendments is an interesting option for field crops, allowing a uniform distribution of fertilizers in a seed batch. This process can be further improved by developing advanced materials for seed coatings that have the ability to carry out the delivery of plant nutrients with greater precision leading to enhanced germination. Herein, we disclose a novel nanoseed coating based on zinc-doped urea−hydroxyapatite nanohybrids synthesized via a one-pot in situ sol−gel synthetic route. The formation of a substituted solid with an altered chemical environment and the lattice shrinkage of hydroxyapatite nanoparticles due to the successful doping of zinc and urea incorporation were evident from characterization studies. The developed nanoseed coating was effective in increasing the rate of growth of Zea mays seeds by ∼69% and the germination rate by 19%, claiming its suitability as a potential candidate for the delivery of nitrogen, phosphorus, and zinc at the seedling stage.

“…Moreover, the coating formula improves plant cultivation by forming an artificial outer layer or surface film, coloring and pelleting 5 . This enhances seed quality and germination, 6 early plant establishment, and abiotic stress alleviation 7 by altering the shape, weight and surface texture of the seed, improving seed–soil contact or manipulating imbibition (the absorption of water in soil) 4,8,9 . More importantly, seed‐coating greatly reduces pesticide applications and therefore environmental pollution.…”

BACKGROUND Coating seed with pesticides is an effective way to control plant pests, however, factory‐based coating processes may carry a potential risk to operational workers of chemical exposure. To study the risk, carbofuran and tebuconazole were used to coat corn seed and their subsequent distribution on the bodies of workers was measured at manufacturers XFS and LS (Shanxi, China). Clothing was collected from workers during operations and analyzed using high‐performance liquid chromatography. RESULTS At XFS, dermal exposure to carbofuran was 4.83, 3.31 and 1.48 mg kg−1, and exposure to tebuconazole was 6.88, 5.16 and 1.72 mg kg−1 for coating, packing and transport workers, respectively. At LS, dermal exposure to carbofuran was 2.32, 0.46 and 0.55 mg kg−1, and exposure to tebuconazole was 1.69, 0.46 and 0.70 mg kg−1, for coating, packing and transport workers, respectively. The level of pesticide exposure was significantly higher for seed‐coating workers than for packing and transport workers. The main area of exposure was the hands for all workers and the lower limbs for packers; exposure was relatively uniform for pesticide handlers. Occupational risk was assessed based on margin of exposure (MOE). In seed‐coating, the MOE was greater than 100 for tebuconazole, indicating no potential risk, but ranged from 0.25 to 2.88 for carbofuran, indicating the risk of a health impact. CONCLUSION The level of exposure varied depending on type of operation undertaken and body parts of workers' body, but the risk of a health impact was highly associated with pesticide toxicity. This provides a guideline for workers in pesticide manufacturing to ensure safe operation of the seed‐coating process. © 2021 Society of Chemical Industry

“…Most seed coatings are based on biopolymers because of their eco-friendly characteristics (they are a renewable source) and production of nontoxic residues when these materials are biodegraded in soil. As a coating, the following materials were tested: starch [ 19 ], gum [ 20 ], gelatin and polyvinyl alcohol [ 14 ], cellulose derivatives [ 7 ], chitosan [ 7 , 20 ], amphiphilic polymers [ 21 ], dolomitic limestone and aluminum silicate [ 22 ], biomaterials based on protein [ 13 ], and others [ 6 , 23 ].…”

Pure silica sol obtained by hydrolysis of tetraethoxysilane and the same silica sol doped with fertilizer Azofoska were used to cover the surface of pea seeds. The surface state of the coated seeds (layer continuity, thickness, elemental composition) was studied by a scanning electron microscope (SEM) and energy dispersive X-ray (EDX) detector. Different conditions such as sol mixing method, seed immersion time, effect of diluting the sol with water, and ethanol (EtOH) were studied to obtain thin continuous coatings. The coated seeds were subjected to a germination and growth test to demonstrate that the produced SiO2 coating did not inhibit these processes; moreover, the presence of fertilizer in the coating structure facilitates the development of the seedling. The supply of nutrients directly to the grain’s vicinity contributes to faster germination and development of seedlings. This may give the developing plants an advantage in growth over other undesirable plant species. These activities are in the line with the trends of searching for technologies increasing yields without creating an excessive burden on the natural environment.
