Definitions
- the present invention relates to a fertilizer composition that includes a plant-assimilable phosphorus and calcium enhancer, as well as the use of said fertilizer composition.
- the invention provides a fertilizer composition that includes glyceric acid as an enhancer of phosphorus and calcium assimilated by plants, where glyceric acid improves the levels of total phosphorus in the plant, its application constituting an alternative to conventional phosphate fertilizers.
- the invention relates to a combination of the described fertilizer composition together with another additional fertilizer and / or biostimulant.
- Phosphorus is an essential macronutrient for plant growth and a determining factor in crop productivity. They absorb it in its soluble forms, mainly H PO4 2 ' and H2PO4 ' .
- phosphorus deficiency is a common problem in agricultural soils due to the low solubility ( ⁇ 1%) of total organic and inorganic phosphorus present in them (Bünemann et al. , “Assessment of gross and net mineralization rates of soil organic phosphorus - A review”, Soil Biology and Biochemistry. 89: 92-98, 2015).
- the main solutions designed to solve the aforementioned problems consist of the use of metal ions complexed with amino acids to improve the solubilization of phosphorus by microorganisms present in the soil (EP3181538A1) or in the application of inocula of microorganisms phosphorus solubilizers (Hu et al., "Development of a biologically based fertilizer, incorporating Bacillus megaterium A6, for improved phosphorus nutrition of oilseed monkfish", Can J Microbiol. 59: 231 -
- plants exude through their roots a considerable part of the organic compounds generated in photosynthesis (between 11 and 40%) in order to regulate the chemical composition of the rhizosphere and promote the growth of microorganisms. that can provide benefits to the plant in a given ecosystem (Badri and Vivanco, “Regulation and function of root exudates”, Plant, Cell and Environment 32, 666-681, 2009; Zhalnina et al., “Phosphorus activators contribute to legacy phosphorus availability in agricultural soils: A review ”, Science of the Total Environment 612 (2018) 522-537, 2018).
- Root exudates include sugars, amino acids, organic acids, fatty acids and secondary metabolites (Bais et al., "The role of root exudates in rhizosphere interactions with plants and other organisms", Annu Rev Plant Biol. 57: 233 -66, 2006).
- the composition and quantity of these exudates are mainly influenced by environmental signals, for example the availability of nutrients in the soil.
- plants have adaptation mechanisms to soils with low assimilable phosphorus, among which is the exudation at the root level of metabolites that increase the solubilization and acquisition of phosphorus and / or that modulate the composition of soil microbial communities. , favoring microorganisms with the ability to solubilize inorganic phosphorus or mineralize organic phosphorus.
- exudates include carboxylic acids, sugars, phenolic compounds, amino acids and even certain enzymes (Carvalhais et al., “Root exudation of sugars, amino acids, and organic acids by maize as affected by nitrogen, phosphorus, potassium, and ion deficiency ”, J. Plant Nutr. Soil Sci. 174, 3-11, 2011; Vengavasi and Pandey, “Root exudation index as a physiological marker for efficient phosphorus acquisition in soybean: an effective tool for plant breeding”, Crop Pasture Sci. 67, 1096-1109, 2016).
- the present invention starts from the aforementioned approaches so that, on the one hand, by regulating the phosphorus transformation processes in soils, root exudates can increase the availability of this nutrient for plants and the efficiency of its use in agricultural soils and, on the other hand, it constitutes an alternative to the use of traditional phosphate fertilizers. Therefore, it would be desirable to have fertilizers that mimic root exudates and have an analogous effect that can make it possible to dispense with or reduce the application of mineral fertilizers and mitigate environmental contamination, and, at the same time, provide an alternative to conventional phosphate fertilization for reduce the pollution derived from its use and increase the efficiency of phosphorus use and the productivity of crops in a sustainable way.
- the present invention fulfills the two objectives mentioned above, providing a fertilizer composition that includes glyceric acid as a phosphorus enhancer assimilable by plants, where glyceric acid improves the levels of total phosphorus in the plant.
- glyceric acid improves the levels of total phosphorus in the plant.
- basic soils pH 8 or higher
- limestone content phosphorus precipitates due to the presence of calcium, giving rise to calcium phosphates.
- the solubilization of insoluble phosphorus will release not only assimilable phosphorus for plants, but also assimilable calcium (Rietra RPJJ, et al., "Interaction between Calcium and Phosphate Adsorption on Goethite", Environ. Sci.
- Glyceric acid or 2,3-dihydroxypropanoic acid, is a trionic acid derived from the oxidation of glycerol that occurs naturally in plants such as those of the genus Brassica (Kim et al., "Metabolic Differentiation of Diamondback Moth (Plutella xylostella (L.)) Resistance in Cabbage (Brassica olerácea L. ssp. capitata) ”, J. Agrie. Food Chem., 2013, 61 (46), pp. 1 1222-1 1230, 2013).

- Examples 1 Assay to obtain and identify root exudates in the absence of phosphorus
- 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 Hoagland 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 absence of phosphorus. The plants grew with a temperature and photoperiod of 25 ° C and 16 h light / 22 ° C 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 phosphorus depletion treatment. For this, three trays were incubated for three days with solution Hoagland modified without phosphorus, 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 abundant water, applying a final wash with distilled water. The plants corresponding to each tray were placed in wide neck flasks containing 200 ml of MilliQ water, the roots being immersed in the water. The plants were incubated in the flasks for 6 h.
- Table 1 shows the metabolites exuded by the plants and their ratios under conditions of absence of phosphorus with respect to the control conditions.
- the 11 coincident metabolites were selected in the exudates of both cultures. These metabolites were: gluconic acid, glyceric acid, lactic acid, glucose, threonic acid, fructose, aspartic acid, serine, glycerol, arabinose and glutamine. 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 6 weeks.
- the effect of the metabolites was compared with a negative control (without treatment) and a positive control with a conventional phosphate fertilizer (triple superphosphate at a dose of 100 phosphorus fertilizer units -P2O5- per hectare).
- the land came from an agricultural soil with a loamy-sandy texture and with an assimilable phosphorus content of 0.5 ppm, considered a very low level of this element for agricultural practices (Practical guide for the rational fertilization of crops in Spain , MAPAMA 2009).
- This level of assimilable phosphorus corresponds to 4.5 kg of P2O5 per hectare (considering 30 centimeters of arable soil and an average density of 1,300 kg / m 3 , the mass per hectare would be approximately 3,900 tons).
- glyceric acid is the metabolite that improves the growth of corn the most, achieving the same result as the conventional phosphating treatment with triple superphosphate.
- compositions in the form of a water-soluble powder were prepared according to the invention with the following composition:
- A 100% by weight of glyceric acid
- B a combination of between 30 and 80% by weight of glyceric acid and between 5 and 30% of gluconic acid, between 5 and 30% of lactic acid and between 5 and 30% of glutamine;
- C a combination of between 30 and 80% by weight of glyceric acid and between 5 and 30% of glucose, between 5 and 30% of fructose and between 5 and 30% of glycerol.
- test 2 the same agricultural soil as test 1 was used, with an assimilable phosphorus content of 0.5 ppm (which corresponds to 1.95 kg / ha of phosphorus and 4.5 kg / ha of P2O5 fertilizer units ) and in total phosphorus of 252 ppm (which corresponds to 983 kg / ha of phosphorus and 2,251 kg / ha of P2O5 fertilizer units).
- treatments A, B and C phosphorus fertilizer units were not provided, since none of the molecules used in these treatments contains this element.
- the soil used has a pH of 8.4 and an active limestone percentage of 14%. These conditions are typical of calcareous soils, in which phosphorus precipitates with calcium, giving rise to calcium phosphates. Thus, in this type of soil, the solubilization of insoluble phosphorus will not only release phosphorus assimilable for plants, but also assimilable calcium.
