Definitions

  • the invention relates to a method for enhancing the breakdown of excessive CO 2 fractions from near-surface areas of the atmosphere.
  • the aim of the invention is to create the possibility of counteracting the increasing content of CO 2 in the atmosphere with simple and inexpensive means.
  • This object is achieved in that the absorption capacity of plants, in particular of younger plants, for CD 2 contained in excess in the atmosphere in a biocatalytic and / or enzymatic way is increased compared to the normal, plant-specific absorption capacity, in particular by at least once the root area irrigated per growing season, and the water used for this purpose is enriched with traces of CO 2 and H 2 CO 3 so that the water has a plant-specific and depending on the soil properties, a predetermined CO 2 content up to a maximum of about 0.5 g / Liters of water and H 2 CO 3 up to a maximum of about 0.015 g / liter of water.
  • the method according to the invention is therefore not only particularly useful for plants in arid or dry areas, but also offers the advantages in temperate zones, provided that it concerns soils which, as is widely the case with old cultivated soils all show an impoverishment of humus.
  • the method according to the invention is for all plants, including trees, bushes, or the like. Suitable for non-cultivated areas as well as for all crops in agriculture. The more spacious the process is used, the greater the effect on the reduction of excess CO 2 from the atmosphere. Young plants with a high level of sponsorship of biomass are particularly suitable.
  • the root growth is favorably influenced both in terms of root length and in terms of the proportion of fine roots.
  • the volume of the soil from which the plant can absorb nutrients is also significantly expanded.
  • H 2 CO 3 in the irrigation water makes the minerals present in or into the soil available to plants by ionization.
  • the plants treated in this way also prove to be more resistant to disease pressure and pest infestation. There are - if necessary at all - pesticides or the like. Treatment agents are usually only required in significantly reduced quantities.
  • the enrichment of the water with CO 2 is preferably controlled so that the proportion of CO 2 is between 0.05 and 0.5 g / liter of water. If one knows the plant-specific dependence of the root grows around the content of the irrigation water in CO 2 or can easily determine it, the upper limit of the content of CO 2 and H 2 CO 3 in the water can be controlled depending on the condition of the soil so that the increase of root growth has reached or just exceeded a maximum value.
  • the supply of CO 2 into the impregnation zone can be regulated continuously and continuously by monitoring the observance of a narrowly limited, plant-specific pH value which is optimally adjusted to positive and negative ionization products in the water.
  • the pH can be set in a range between 5.5 and 7.5 - preferably between 6.0 and 7.0. It should be noted that it is not nutrient salts as such, but only their ionization products that are available to the plants. The ionization of such nutrients depends on the pH value.
  • the carbonic acid contributes to the ionization of all important Add nutrients and trace elements by providing the necessary H + ions.
  • the processes can be further favored by adding small amounts of water to the water depending on its chemical nature and the nature of the soil of one or more of the trace elements from the group Mn, Mg, Zn and Fe 2 .
  • Evaporation film must pass through the carbon dioxide if it wants to get inside the plant to trigger photosynthetic effects.
  • the laws of the solution of carbon dioxide in water apply here, i.e. no longer those of the atmosphere.
  • carbonic acid, H 2 CO 3 and their dissociation forms, chemically dissolved, while the carbon dioxide remains physically bound and thus exerts a buffering effect.
  • the low temperature of the evaporation film favors absorption capacity and binding of the physically dissolved carbon dioxide.
  • the CER factor can thus also be controlled by the plant.
  • the amount of CO 2 supplied per liter of water is continuously and sensitively regulated depending on the nature of the water.
  • the basic amount of CO 2 can be roughly adjusted depending on the pressure or the amount of water flowing in, while the fine control of the CO 2 content takes place depending on the nature of the water in the sense described above.
  • the invention therefore presupposes that not only is impregnated with high precision, but that the water quality is continuously monitored by means of fine control so that the sources of error are minimized and the highest possible CO 2 binding takes place from the atmosphere.
  • Z. B the proportion of water in ionizable minerals and trace elements. These can buffer part of the impregnated carbon dioxide, making it difficult to achieve a correct setpoint for CO 2 binding.
  • the water has a different pH value, which in turn is influenced by the CO 2 supplied and the chemical bonding of H 2 CO 3 triggered thereby.
  • the invention provides that the impregnation device continually responds to fluctuations in the quality of the water and controls the dangers of an overdosing and underdosing of CO 2 .
  • the pH of the water is only slightly lowered, with the nature or quality of the water being taken into account to a high degree.
  • the target value for the base / acid content of the water is expediently set depending on the specific need of the crop plants for plant-available ionization products and / or also on the culture soil content of nutrient salts which are to be made available to plants by ionization.
  • control option here is so precise that even fluctuations in the nature or quality of water from the same water source can be taken into account and compensated for in the influence on the activation of the desired base / acid value.
  • the missing minerals and / or trace elements can be added to the water.
  • An important side effect of the use according to the new process is - at least in the area of crop plants intended for nutrients - that the plants are demonstrably enabled by the treatment of the plants with the process according to the invention to preferentially break down excess nitrogen compounds built into the biomass, so that the contamination of the nutrients with too much nitrogen compounds is markedly reduced, which makes expensive processes for eliminating the excess compounds from the nutrients (see fax copy, quality certificate of the Danish plant research).
  • Fig. 1 shows an apparatus for performing the method
  • Fig. 2 illustrates the leveling of the actual value to the desired value.
  • FIG. 1 shows a water supply line 1 through which the irrigation water is continuously fed to a CO 2 impregnation zone.
  • the impregnation zone is represented in FIG. 1 by an impregnation device 2.
  • This is e.g. B. the already mentioned and known under the trademark "Carborain” impregnation device.
  • the device is connected via line 3 to a CO 2 gas pressure source, not shown and indicated by the arrow 4.
  • a throttle valve or a feed nozzle 5 with a variable throttle or nozzle cross section is provided in line 3.
  • the cross-section is adjusted with the aid of a stepper motor 6, which is controlled by a control device 8 via line 7.
  • This has an input 9 connected to a probe 11 in line 1.
  • the probe can be a pH electrode, for example.
  • Another input 10 is provided for manual adjustment of the setpoint specification. Detailed instructions have already been given above for determining this setpoint. It is sufficient to point out that the setpoint can be determined plant-specifically and depending on the soil conditions
  • the probe 11 already shows the slightest changes in the pH of the impregnated water.
  • the control unit reacts sensitively to these values with control signals for the stepper motor, which continuously and sensitively controls the gas inflow cross-section of the valve or the throttle 5 controls.
  • the target value is activated in the manner shown in FIG. 2 by leveling the actual value to the set target value.
  • the leveling process takes place quickly and with great accuracy.
  • a quantity measuring device can be provided in line 1, which actuates a valve 15 for rough control of the gas supply via control device 8.
  • a impregnation zone can be connected to the impregnation zone, which provides the water impregnated with CO 2 bubbles with a sufficient dwell time, thereby causing the volume of any gas bubbles to pass through
  • the grain yield was 87.8 dt / ha
  • the straw yield 87.8 dt / ha and thus the C content in the entire biomass was 7480.56 kg / ha.
  • the grain yield was 92.7 dt / ha and 92.7 dt / ha for the straw yield, or a C content in the biomass of 7898.04 kg / ha.
  • the additional yield of carbon in the biomass is 417.48 kg.
  • the amount of carbon originally introduced into the irrigation water by the CO 2 (2.25 kg / ha) was only 0.61 kg.
  • the proportion of 417.48 kg of carbon corresponds to 1531 kg / ha of CO 2 , which the plants treated according to the invention removed more than untreated plants from the surrounding atmosphere. Corresponding a factor of 684, based on the CO 2 content in the irrigation water.
  • water was irrigated with 300 m 3 of water / ha.
  • the CO 2 content of the water was set at 0.25 kg / m 3 .
  • the CO 2 values measured in the root area were on average only about 0.01 to 0.02 g / liter below the initial values. For comparison, an area of the same area was irrigated with the same amount of water, but without CO 2 .
  • the invention results from
  • CO 2 can also be used from exhaust gases, from internal combustion engines, and such exhaust gases can be collected to a sufficient extent and introduced into water tanks.
  • the factor by which the plants break down an additional volume of CO 2 from the atmosphere compared to the CO 2 used in the irrigation water can be up to a thousandfold depending on the type of plant.
