Definitions

  • the invention relates to inorganic and organic soil improvers with the use of humic acids and organic feeds to increase the sorption capacity of soils, for improved sustainable plant nutrition, for improving water storage capacity and for improving the curative effect on plants in stressful situations, especially in the restoration of threatened soils and Landscapes, such as in recultivation of mountain pasture landscapes or when used in raw soils from sand (deserts) in arid and semi-arid climates, but also when used in disturbed soils of all other climates.
  • humus The proportion of soil organic matter, also called humus, is of great importance for soil fertility. Humus rich soils are better aerated, are less soiled, are easier to work. Floors with high humus contents generally have better water and nutrient retention capacity, so that the risk of nutrient leaching is reduced.
  • Humic acids are the essential constituent of a significant fraction of humus, the humic substances that are formed in the natural cycle from biologically transforming plant materials. They are intermediates in the conversion of plant material under geological conditions into petroleum and hard coal. Up to 50% of its mass contains humic acids in the younger forms of peat and lignite.
  • the present document describes a process for the preparation of a solid soil additive based on humic acids, as well as fulvic acids and their Salts, as well as other inorganic and organic components, which can be used without changes to the soil.
  • the effect of the soil additive is a direct effect on the water storage capacity of the soil in the form of plant-available water to increase the usable field capacity.
  • the mixture of the proportions of organic matter of different origin and different ages with the humic and fulvic acids comes in its composition already close to natural humus occurrences.
  • the individual components complement each other in their physical, biological and chemical action, so that a consumption of the substances in the soil takes place and the effect does not subside.
  • the combination of the substances ensures the best possible design of the soil water-air balance.
  • the natural soil functions can be produced as sustainably as possible.
  • Farmyard manure acts to improve the soil and nutrients to the soil. It has been shown that manure The ability to retain light sandy soils and positively influence the air balance of soils The duration of action of manure is, however, relatively low. Humic acids are almost nonexistent.
  • Residues from the digestion of manure, green waste or organic waste for soil improvement can also be used.
  • Compost has a high air capacity. Its water retention capacity is low. Biodegradation by soil-borne bacteria takes place within a few weeks.
  • Bark mulch is raw, unfermented (not composted) bark.
  • Bark humus is composted bark. Growth-inhibiting substances are converted here during the composting process to short-chain humus substances. Bark humus has both soil-improving and fertilizing effects.
  • Bark substrates are clay, mortar or other aggregates prepared finished culture substrates or planting plants with 30 to 60% - proportion of bark humus.
  • FR-PS 2 123 042, FR-PS 2 224 421, DE-PS 2 651 171 and DE 3 040 040 have disclosed methods for composting and humification of comminuted bark, according to which additional inorganic nutrients or peat are used in the composting process is added to improve the product properties.
  • all of these products have a lower water retention capacity, i. more frequent watering is required.
  • Nutrient sorption is also limited.
  • the effect as a permanent humus is limited, the degradation by soil bacteria is also like compost within a few weeks.
  • wood waste substrates are also used. These specially treated wood waste products, like bark humus, have a low water retention capacity. Wood fiber materials that are not are fertilized, in addition to bark humus additionally lower nutrient contents. Untreated wood waste, such as sawdust or wood chippings, fixes nitrogen in the soil, ie nitrogen must be added during the application of such substances. When using sawdust, it must be mixed very intensively with the soil, as sawdust nests prevent the penetration of water into the soil. The use of pure wood products for soil improvement is thus rather disadvantageous. Therefore, wood fiber materials are often fertilized or used as culture substrates additionally in mixture with peat or clay.
  • humic acids Another source of humic acids are substances of the coconut processing industry, in particular the otherwise poorly used short and dusty wastes of fiber processing.
  • the classical method for the extraction of humic acids is the extraction of peat or lignite with dilute aqueous sodium or potassium hydroxide solution.
  • the humates dissolve in the extraction solution and are separated by filtration, decantation or centrifugation from the undissolved peat or coal components. After acidification of the extract with excess mineral acid, water-insoluble humic acids are formed, which can be separated.
  • For use as a soil conditioner predominantly lignites are extracted with aqueous ammonia, as set forth in US Patent 3,770,441. The resulting extract is then neutralized with phosphoric acid and enriched with micronutrients.
  • the extraction solutions obtained are highly diluted and, for further use as soil improvers, generally have to be concentrated with expenditure of energy.
  • US Patent 4319041 describes that humic acid-containing coal is mixed with water and extracted with aqueous solutions of sodium hydroxide solution, potassium hydroxide solution or ammonia with stirring so that the pH remains in the range of 6.5-8. The process is finished after 40 hours. It is obtained a highly diluted humate solution, which is also complicated, separated from the coal residue and then must be concentrated.
  • US Patent 3,076,291 lignite is extracted with dilute aqueous NH 3 , KOH or NaOH solutions. The separated from the coal residue, then concentrated and neutralized humic solutions are used as a means of improving the germination of the seed.
  • Laid-open publication DE 19859068 A1 describes that lignite is suspended in an aqueous-ammoniacal medium having a pH of greater than 9 and is partially dissolved and oxidized in the aqueous-ammoniacal medium.
  • the organic fertilizer is recovered after thickening or drying as a dispersion.
  • the starting brown coal can be added to this process with additions of lignin or cellulosic products from industry and forestry. An addition of macro and micronutrients is possible.
  • the method avoids the complicated separation of humate solution and coal residue, but requires additional energy to thicken or dry the product and opens due to the low basicity of NH 3 to alkali only a small proportion of humic acids contained in the coal.
  • an additional oxidation step is incorporated instead, which increases one means technical effort and increases the amount of available humic acids only slightly.
  • US Pat. No. 5,874,479 describes a soil improver based on humic acids, for the preparation of which an aqueous solution of humates is successively mixed with sodium bicarbonate for pH reduction, a protein source such as animal meal or blood, citric acid, yucca extract, lime and Tang is transferred. This suspension is then fermented for 10 days. The solution obtained after separation of insoluble constituents is used as a soil improver.
  • DE 101 23 283 describes a process by which fine-grained lignites are digested in alkaline solution and, after addition of inorganic supplementation and / or neutralization substances without further treatment steps, a stable humate-humic acid-continuous humus nutrient suspension is produced.
  • This product has been proven in practice, but the effect is limited in extremely nutrient-poor soils.
  • the published patent application DE 43 25 692 A 1 describes the structure of a hydrophobic layer in the soil to contain the evaporation, ie the water Verduns from the ground.
  • the approach used in the present patent is to curb transpiration, that is, consumption over the plant itself.
  • Hermsen describes in his publication from 1994 the combination of energy production and extraction of water from the humidity for use as irrigation, or irrigation water in deserts.
  • inorganic and organic substances are used.
  • the use of artificial inorganic and organic soil improvers in the form of polymeric and hydrogels capable of reversibly storing water is also increasing. In most cases, these substances are only partially usable for use in desert soils, as these substances are not heat tolerant, only limited UV resistance and are no longer functional at high salt levels in the soil.
  • artificial soil conditioners still have a number of unanswered questions regarding the metabolites that may be produced by natural degradation or chemical conversion in the soil.
  • rock flours and clay minerals are intensified, but their effect is limited; Some of these still have antagonistic effects in the soil with regard to the availability of potassium and magnesium, since in the two-layered and three-layered clay minerals in particular potassium and magnesium are stored, which is no longer available to plants under dry soil conditions.
  • the primary goal in using the soil adjuvants described here is to increase the water retention capacity while stimulating biological activity to build up a working soil.
  • One of the secondary objectives in the regeneration of soils is to increase the nutrient sorption capacity of substrates and soils that are disturbed in structure and composition.
  • the nutrient balance and the absorption capacity of nutrients in the plant should be favorably influenced, so that the water consumption is minimized by the plants as possible.
  • the nutrient potassium is easily washed out during heavy rainfall events and has particular importance in the metabolism of the plant to control the water balance via the internal cell pressure in the stomata.
  • the transport of potassium in the soil via diffusion which is possible only to a limited extent on dry soil.
  • Humic acids are of particular importance in the soil-plant-water balance. As so-called chelating agents, they are capable of reversibly binding and releasing potassium ions at the ends of their molecular chains.
  • the object of the invention described here is to produce a simple product for use as an aqueous solution or as a substantially solid product for improving the soil-plant water balance, which is useful for revitalizing, grounding and supporting the growth of infertile and nutrient-poor soils such as mining dumps. Landfills and problem areas, desert and steppe areas and sea coasts can be used by providing a universally applicable in all climates and soil types organic soil conditioner, with little technical effort.
  • the inorganic and organic components of the product release in the biochemical reaction in the soil potassium, which can be reversibly provided by the chelating agents of the plant root. Due to the high proportion of carbonaceous components, nitrogen released from the mineralization of the fresh organic substance is immediately biologically stabilized.
  • the soil adjuvant acts via two paths: the formation of the soil with its original functions and the supply of the plant through an improved supply of nutrients, in particular potassium.
  • a process according to the invention for the preparation of an inorganic and organic soil adjuvant based on humic and fulvic acid comprises the following steps: a) digestion of a lignite constituent and / or a geological lignite precursor, in particular xylitol, Leonardite or a mixture of these substances, by means of an acid and subsequent Abpuff ceremonies with an alkali or by means of a lye and subsequent buffering with an acid, the Abpuff proceedings also in a later Process step can take place; b) filtration of the intermediate product obtained in step a) and further use of either the filtrate or the solid filter residue or a mixture of filtrate or filter residue not having the original mixing ratio before filtration; and c) adding fulvic acids having a weight fraction of at least 1% on the finished product, and adding at least one further organic constituent.
  • brown coal constituents or precursors creates a humic acid-containing product precursor with a pH value pre-set and buffered by the acid / base additions, which ensures good water retention capacity over long periods.
  • This precursor is still specifically enriched by separately added fulvic acids, as they can be obtained for example from the water treatment.
