“…Biostimulants based on amino acids are produced through chemical synthesis from plant proteins, such as algae, maize or soyabean [9]. Another source is chemical or enzymatic hydrolysis of animals or plant proteins [5,[10][11][12][13][14][15][16].…”

“…Liuciatelli and coworkers indicated that a protein hydrolysate-based biostimulant derived from a legume and another product derived from tropical plant extracts altered the composition of the plant growth-promoting microbial population in lettuce [24]. Popko and coworkers demonstrated the potential of biostimulation of plants by foliar application of preparations based on keratin hydrolysates obtained from feathers [15]. The authors reported an increase in the yield of plant crops when compared to a control group and indicated that the increased efficiency of the tested biostimulants arose from the presence of micro-and macronutrients in hydrolysates of keratin protein.…”

Mechanism of nutrition activity of a microgranule fertilizer fortified with proteins

et al. 2020

Background: A microgranule fertilizer was designed for localized fertilization of soil with controlled release of nutrients. The microgranule matrix was fortified with proteins, which were obtained from food industry byproducts or waste, i.e., whey protein from milk serum, soy protein from soy isolate and egg white protein from chicken egg white powder. The mechanism of the protein decomposition and migration of micro and macromolecule compounds through two different model soil systems was investigated. The potential of the protein fortified fertilizer for localized fertilization of the potted maize seeds was evaluated. Results: The study revealed that proteins slowly diffused through soil with simultaneous degradation, which was accompanied with release of ammonia ions. The highest concentration of proteins and degradation products was found in a close vicinity of the microgranule. The microgranules were used as a local fertilizer for maize seeds in the pot experiments. The experiments confirmed statistically significant improvement in root density of maize plant compared to control group. Conclusions: Byproducts or waste of food industry, such as the milk serum and soy can be used as a source of proteins that degrade in soil without a pretreatment. The degradation is accompanied with formation of ammonium ions, which can be utilized by plants as a nitrogen source. The fertilizer microgranule should be placed in a close vicinity to the plant seed, since the maximum of the protein concentration and ammonia ions is reached at a very close distance from the microgranule.

“…Substances derived from amino acids (AA) constitute an important group of biostimulants. Their foliar application can improve acquisition of microelements (Kałużewicz et al 2018, Popko et al 2018. Modification of sugar content can be strengthened using commercial biostimulants such as Asahi SL and Kelpak SL (Zarzecka and Gugała 2018).…”

The increasing world population and limited amount of land area appropriate for intensive agriculture necessitate highyield cultivars. The focus is on the enrichment of existing crops deficient in nutrients, which is also called biofortification. Microelements, vitamins, and fatty acids belong to most important traits being subjected to biofortification. Biofortification strategies can be divided on fertilization-based strategy, which is characterized by direct application of nutrients or plant growth promoting substances on plants, and biotechnological strategy, which involves molecular biology techniques in order to enhance transport, production, and accumulation of nutrients. Recent advances in plant biotechnology, such as genome-editing, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9), and transcription activator-like effector nuclease (TALEN), as well as an extensive study of genetic diversity, are acceptable approaches to the development of biofortified crops.

“…Besides, they include growth regulators. The creation of complex preparations of microelements and growth regulators for foliage application is one of the main directions to optimize plant mineral nutrition [22]. In addition, modern liquid complex fertilizers with growthstimulating effect can play a significant role in crop management technologies, including soybeans [23].…”

Use of foliar fertilizers on soybeans in the Republic of Tatarstan

In 2018, studies were conducted to assess the impact of foliar feeding with complex fertilizers on the yield and grain quality of two soybean varieties. Weather conditions throughout the year were noted periodically dry in May, June and August. Metallocene® fertilizers with different mineral nutrition elements were used for soybean spraying. The fertilizers were used for spraying in the soybean beginning bloom stage. Еру control served as a variant without foliar feeding. It was found that the variety Annushka in the conditions of 2018 was more productive than the variety Milyaushaa. The difference between the varieties in the control was 0.3 t/ha. Low yield in the control sample was associated with the negative effect of drought on the existing root system and the nudeles on it. Spraying Annushka crops by Metallocene® A with copper has high positive effect on the yield. The yield increase from this fertilizer was 0.72 t/ha. In case with Milyaushaa, the best indicators were achieved by Metallocene® D spraying with manganese. In case the yield increased by 0.79 t/ha. The use of foliar feeding had positive effect on soybean seed size. The maximum 1000 seed weight Annushka was for Metallocene® A with copper. For Milyaushaa the largest seeds were when using Metallocene® D with manganese. Foliar feeding by Metallocene® D with manganese had positive effect on phosphorus accumulation in seeds.
