Definitions

  • the present invention belongs to the chemistry section, as it is a process of preparation of organic-mineral compound for use in agriculture.
  • Nitrogen is one of the most necessary elements for the proper development of plants, because it makes up the structure of nucleic acids and proteins, and is considered one of the most important nutrients (DOBBELAERE & OKON, 2007).
  • the importance of nitrogen is so important for plants that it becomes an extremely limiting element for the yield of grasses such as wheat and rice, and especially for those with high grain yields such as corn.
  • nitrogen fertilizer is a common practice and is responsible for raising the costs of agricultural production.
  • N 2 The main source of nitrogen is the atmosphere, which has approximately 78% N 2 (TAIZ & ZEIGER, 2004). However, this amount is not directly available to living beings and to be used because it needs to be fixed through industrial or natural processes (NUNES et al., 2003).
  • nitrogen is found in organic form, in organic matter; mineral, in soil solution and adsorbed to clays; and gaseous in the pores. Its main forms available are ammonium (NH 4 + ) and nitrate (NO 3 " ).
  • Nitrogen in its gaseous form is generally biologically fixed in other nitrogenous chemical species and is mobilized by some organisms, which employ it in protein and nucleic acid biosynthesis (NUNES et al., 2003).
  • Biological nitrogen fixation represents the main way to fix atmospheric N 2 in ammonium, revealing a key point of entry of molecular nitrogen into the biogeochemical nitrogen cycle (TAIZ & ZEIGER, 2004).
  • nitrogen provided by the biological fixation process is less prone to leaching and volatilization and is better employed as it is used in situ. In this sense, it can be noted that the biological process is a cheap, clean and sustainable alternative to the supply of nitrogen in commercial agriculture (HUERGO, 2006).
  • microorganisms As a fundamental tool of agriculture, there is the use of microorganisms, among the various types, some bacteria stand out; as asrizobacteria and those of the genus Azospirillum.
  • the use of microorganisms in agricultural practices is very relevant, since nitrogen fertilization represents an important part of the production costs of non-legume crops.
  • the benefits obtained by inoculating bacteria are varied and described as direct and indirect; among these benefits stand out as direct: the process of biological nitrogen fixation; phytohormones production, especially auxins and inorganic phosphate solubilization. Indirect benefits are related to systemic induction of disease resistance, biological control and production of iron-trapping organic compounds (DOBBELAERE & OKON, 2007).
  • Azospirilium brasilens is the class of plant growth promoting microorganisms because they are bacteria that contribute a number of benefits to the plant including biological nitrogen fixation and phytohormones production such as auxins and gibberellins, Plant growth hormones that act particularly on root development. Larger roots allow the plant greater absorption of water and nutrients, which makes it more resistant to water stress, and provides greater resistance to disease, as plants have better nutrient and water balance and are therefore healthier.
  • WO96 / 34840 entitled “Bacterialfertilizerandproductionprocess” describes a biofertilizer comprised of an aqueous suspension containing cells from the strains of the microorganisms Azotobactervinelandii and Azozpirillum brasilense; and the method for obtaining these microorganisms, which were specifically developed to obtain better nitrogen fixation and to potentiate alginate biosynthesis.
  • the biofertilizer contains in its formulation in addition to microorganisms, sucrose, PO 4 HK 2 , PO 4 H 2 K, SO 4 Mg, SO 4 Ca, SO 4 Fe, sodium molybdate and water.
  • PI 0722102-9 entitled “New Biological Fertilizer, Method for Obtaining It and Using It as a Plant Growth Stimulator” which relates to a product for biological fertilization consisting of a granulated formulation comprising two strains of bacteria of the genera Azospirillum and Pantoea, capable of fixing atmospheric nitrogen, solubilizing phosphates and other soil mineral nutrients and producing high amounts of plant growth stimulating substances.
  • the purpose of this application is to provide a biological fertilizer that exerts fertilization action and / or stimulation of plant growth.
  • the objective of the present invention is to provide an organic-mineral compound which, under conditions favorable to the proliferation of bacteria essential for agriculture, makes the fixation and mobilization of nitrogen, phosphorus and potassium more efficient for plants which are treated with it. . OF THE INVENTION
  • the present patent application relates to a process of preparation, with simple implementation steps, of a solid organic-mineral compound capable of providing a favorable environment for the proliferation of bacteria essential for agriculture, more precisely. Azospirillum brasilense bacteria, and thereby make the fixation and mobilization of nitrogen, phosphorus and potassium more efficient for plants that are treated with it.
  • the present invention has as its main advantages:
  • S Provide an organic-mineral compound that provides a favorable environment for the proliferation and development of Azospirillum brasilense, microorganisms essential for agriculture; Provide an organic-mineral compound that allows the fixation and mobilization of NPK (nitrogen, phosphorus and potassium), due to the good development of Azospirilium brasilense bacteria;
  • NPK nitrogen, phosphorus and potassium
  • ORGANIC-MINERAL COMPOUND PREPARATION PROCESS FOR AGRICULTURE AND OBTAINED PRODUCT (Fig. 1) takes place through simple production steps: Initially each of the components (C) is separated (E1) and then weighed (E2). ). For the preparation of the organic-mineral compound, between 55 and 65% of the total mass of the mixture, Azospirilium brasilense (1), available on the market, between 15 and 25% of the total mass of the mixture, conditioners are used. soil (2) composed of Humic and Fulvic Acids, also commercially available; between 15 and 25% of the total mass of the mixture, hydrogel (3), composed of CO 2 , H 2 O and KCI and, as the others components (C) available on the market.
  • the mixture (4) can be stored (E4) in vacuum plastic packaging for up to 04 months in a dry place at room temperature; or immediately applied (E5) to soil with seed, seedlings or pre-sprouted seedlings.
  • Ready-made organic-mineral compound (4) has acidic pH, between 4.5 and 5.5; and, it is applied (E5) directly to the soil with the seed or seedling, or pre-sprouted seedlings; replacing the traditional ways of preparing counterparts in concrete mixers or improvised equipment. Once incorporated into the soil, compound (4) promotes the development and proliferation of the bacteria (2) that compose it. This form of application of the compound (4) in the soil ensures that there will be no loss of biological material as it does not require preparation before application and its "activation" will be done after incorporation into the soil along with the seed.
  • compound (4) to the soil together with the seed at the time of planting offers a favorable biosystem for the growth and multiplication of bacteria, which favors the good plant development, due to the factors previously presented.
  • Compound (4) can still be applied to already planted and established plants to improve their development, rooting and health.
