Definitions
- the present invention refers to a fertilizer composition that includes a nitrogen enhancer assimilable by plants, as well as the use of said fertilizer composition
- the invention provides a fertilizer composition that includes tyramine as a nitrogen enhancer assimilated by plants, where tyramine improves the levels of total nitrogen in the plant and of nitric nitrogen in the sap, its application constituting a alternative to conventional nitrogen fertilizers
- the invention relates to a combination of the fertilizer composition described June with another additional fertilizer and / or biostimulant.
- Nitrogen is the mineral nutrient required in greater quantities by agricultural crops and a key factor limiting their productivity. It is estimated that, at the global level, agricultural systems need between 150 and 200 million tons of nitrogen annually, of which more than 100 are obtained industrially through the Haber Boscb process and between 50 and 70 are fixed biologically (Unkovich et al, 2008, “Measuring plant-associated nitrogen fixation in agriculture! Systems”, Australian Center for Internationa! Agricu ⁇ tural research, Canberra, Australia .; Lu and lian, 2017, “Global nitrogen and phosphorus fertilizer use for agriculture production in the past half century: shifted bot spots and nutrient imbalance ”, Earth Sys Sci Data.
- plants exude through their roots a considerable part of the organic compounds generated in photosynthesis (between 1 1 and 40%) in order to regulate the chemical composition of the rhizosphere and promote growth.
- those microorganisms that can provide benefits to the plant in a given ecosystem (Badri and Vivanco, 2000, "Regulation and function of roo exudales", Plant, Cel! and Environment 32, 666 -681; Zhalnina et al., 2018, “ Dynam ⁇ c root ex ⁇ date chemistry and microbial substrate preferences dr ⁇ ve patterns in rhizosphere microbial community assemb ⁇ y ”, Nat Microbio !, 3 (4): 470- 480).
- Root exudates Compounds present in root exudates include sugars, amino acids, organic acids, fatty acids, and metabolites secondary (Bais et al, 2006, "The role of root exudales in rhizosphere interactions with plants and other organisms", Annu Rev Piant Biol. 57: 233-66).
- composition and quantity d of these exudates mainly influence environmental signals, for example, the availability of nutrients in the soil.
- root exudates can modify the composition of soil microbial communities and influence the dynamics of the nitrogen cycle, mainly through the regulation of nitrification and nitrogen fixation processes from the air (Sun et al 2016, " Biológica! Nitrification inhibitson by rice root exudates and its relationship with nitrogen-use efficiency ", New Phytol. 212 ⁇ 3); 646-656: Coskun et al, 2017,” How Plant Root Exudates Shape the Nitrogen Cycie ", Trends P! ant Sci. 22 ⁇ 8): 681-873).
- the present invention is based on the aforementioned approaches such that, on the one hand, by regulating the nitrogen transformation processes in soils, root exudates can increase the availability of nitrogen for plants and the efficiency of its use in agricultural soils and, on the other hand, constitutes an alternative to the use of traditional nitrogen fertilizers.
- the present invention fulfills the two objectives mentioned above, providing a fertilizer composition that includes tyramine as an enhancer of nitrogen assimilable by plants, where tyramine improves the levels of total nitrogen in the plant and of nitric nitrogen in the sap.
- Tyramine or 4- ⁇ 2-aminoethiS) phenol
- Biochemically, tyramine is produced by decarboxylation of tyrosine via the action of the enzyme tyrosine. decarboxylase, being obtained in the form of a white crystalline powder with a purity greater than 99.5%.

- the poSiamines are preferably selected from among putrescine, spermidine, spermine and mixtures thereof.
- the presence of these other components other than tyramine in the composition of the invention is based on the fact that such components form part of the root exudates in the crops tested in the absence of nitrogen which are described later or are described in the literature as components of said exudates under normal conditions for the development of the plant (Zhalnina et al., 2018), being therefore desirable desirable in order to have a fertilizer composition that mimics root exudates with an analogous effect that may allow dispensing or reducing the application of mineral fertilizers.
- the fertilizer composition of the invention is formulated in the form of a water-soluble powder, as indicated above, but it can also be formulated as a liquid composition by dissolving it in water or in granular form by adding granulating agents known to those skilled in the art. matter
- the invention refers to a fertilizer composition as described above in combination with another additional fertilizer selected from among nitrogen fertilizers, phosphate fertilizers, potash fertilizers, calcium fertilizers and amendments, micronutrients, boric acid and leonardite, as well as combinations thereof, and / or in combination with one or more biostimulants selected from the group consisting of hydrogenated amino acids, humic extracts, extracts from algae, live microorganisms or extracts of microorganisms, for example Pichia guiiHermondü and Azotobacfer chroococcum, and combinations thereof.

- the seeds were allowed to germinate in the dark for 4 days, after which the seedlings were placed in hydroponic cultivation trays, immersing the roots in standard Hoagiand nutrient solution. 12 plants were placed in each tray, with three trays (each corresponding to a biological repetition) being used for the control treatment and another three for the nitrogen-free treatment. The plants grew with a temperature and photoperiod of 25 ° G and 16 h light / 22 Q G and 8 h darkness and a light intensity of 4,000 lux on the surface.
- the nutrient solution was replaced by fresh solution every three days and was kept aerated at all times by means of bubble tubes. After 10 days of growth, the plants were subjected to the nitrogen depletion treatment. For this, three trays were incubated for three days with modified Hoagiand solution without nitrogen, incubating the three remaining trays with complete solution. After the incubation, we proceeded to obtain the root exudates The plants were carefully removed from the culture trays and washed with copious amounts of water, with a final wash with distilled water. The plants corresponding to each tray were placed in wide necked flasks containing 2GQ ml of MilliQ water, leaving the roots immersed in the water. The plants were incubated in the flasks for 6 h.

Each of the metabolites was applied separately at a dose of 1 kg / ha in a pot with 3 kg of soil, corn plants were sown (4 pots per treatment with one plant per pot) and the effect on their weight was observed. dry at 8 weeks.
- the effect of the metabolites was compared with a negative control (without treatment) and a positive control with a conventional nitrogen fertilizer (ammonium nitrosulfate at a dose of 300 nitrogen fertilizer units per hectare).
- the land came from an agricultural soil that had remained a year without fertilizing or cultivating, conditions under which the availability of forms directly assimilable by plants (NHU + and NOs) is generally low (Kiba and Krapp, 2016, “Plant Nitrogen Acquisition Under Lo Availabiiity: Regulation of Uptake and Root Arcbitecture ”, Plant Ceil Physiol, 57 ⁇ 4): 707-14). All metabolites enhanced corn growth as shown in Table 2 below.

- treatment B in the following combination: 35% tyramine, 5% sucrose, 30% glutamic acid and 30% urea.
- the nitrogen content of this mixture would be 20.22%, which would imply a maximum application of nitrogen fertilizer units through the treatments described here of 15.4 kg / ha in the case of corn and 10.1 kg / ba in the case of tomato.
