Definitions

  • This invention relates to improvements in and relating to fertilisers More particularly, it relates to a method of, and compositions for, correcting soil pH and supplying nutrients to the soil, m accordance with soil requirements, in a single application
  • soil is degraded That is, because of nutrient loss caused by erosion, long periods of cultivation, building activities or simply poor inherent structure (for example, a clay or boggy soil), the soil structure is commonly less than ideal for cultivation purposes and associated types of land use, for example farming, planting, domestic lawns and gardens, and so on
  • fertilisers farmers and all users of fertilisers have numerous commercial products available to them that are known as conventional fertilisers These consist of natural mined resources which are processed to form these products Most of these commodities are subjected to losses when applied through leaching or fixation
  • fertilisers are applied as solids Problems that occur include loss of fine particles (being blown away from the area where they want it applied), difficulty in drilling in damp conditions where they clog up the application machinery, and cleaning of equipment to continue application
  • a further important effect of fertiliser application is pollution of rivers, lakes, underground water and the sea, se ⁇ ously affecting the ecology
  • Mixtures of conventional fertilisers also have the problem of fixation, not only by the ingredients but also with the soil nutrients
  • Some of the mate ⁇ als are harmful to the soil itself and destroy humus as well as killing off the soil organisms, thus depleting the natural process that these organisms perform which maintain the fertility of soils All these effects are expensive for a farmer to deal with
  • farmers plant seeds for crops that may firstly require a soil pH correction then apply a fertiliser that has a low nitrogen content and a high phosphate and potassium content, as well as a balance of the other nutrients
  • a commercial fertiliser needs to be applied separately to stop wasteful immobilisation and to get the best nutrients for seed germination. Once the seed emerges from the ground, the shoots need to have more nitrogen m the balance of nutrients for the leaves to develop, so that photosynthesis will proceed at a maximum rate.
  • Some crops require the correct soil pH so that the root system is not infected by fungal development (for example a pineapple crop needs the soil pH to be below 5 to prevent fungal development leading to loss of the root system). Correcting this problem is expensive.
  • lime is usually applied.
  • Lime when mined, consists of calcium carbonate of various grades of purity and exists as a solid mass that needs to be ground before being applied on soils to correct acidity.
  • the particle size is important, since the smaller the particle size the greater the surface area per unit volume, and thus the more easily of the material can pass into solution. Lime needs water to dissolve to begin its antacid action.
  • lime is applied by solid application, to he on the ground surface to be washed into the soil by rainfall or by use of lr ⁇ gation water.
  • the ionic elements that determine the Base Saturation include: calcium, magnesium, sodium and potassium cations
  • anions formed from acids or from fertiliser which is applied that break down to form acid also affect pH.
  • the normal practice of applying lime and conventional fertilisers are all subjected to losses
  • the cation and anion holding ability of the soil is a function of the colloidal content of the soil and the amount of organic mate ⁇ al present, which determines the Cation Exchange Capacity of that soil.
  • Alkaline soils that have a pH higher than 7 do not need lime Instead they need acid-formmg fertilisers to reduce the pH.
  • Nitrogenous fertilisers are used for this task, and also elemental sulphur which, when acted upon by sulphonating bacte ⁇ a in the soil, form sulphate, an acid radical which lowers soil pH.
  • topsoil With respect to the domestic situation, when new buildings are erected, the topsoil is removed to allow a solid foundation. After completion of the house only a thin layer of topsoil is replaced.
  • the owner of the property has a problem with turning the resulting clay soil to workable fertile soil. When it rams the water collects in pools m the basins, where few plants can grow.
  • the clay consists of fine particles, causing muddy soil that d ⁇ es out and becomes very hard. Nut ⁇ ents needed for plants to grow are washed away and is difficult to dig.
  • compositions for application to a substrate being a predetermined composition and pH, characterised m that said composition includes a protective material, which is selected from the group
  • said protective mate ⁇ al having clathratic properties and being further characterised in that
  • the protective material when said protective mate ⁇ al is free of polyvalent cations and the mate ⁇ al is dissolved m water, added to water or when water is added to said mate ⁇ al, the protective material is free of any gel-forming property, but when polyvalent cations are introduced to the protective mate ⁇ al in the presence of water, the protective material forms a gel that thickens, and further characte ⁇ sed in that when said protective material includes polyvalent cations and the mate ⁇ al is dissolved in water, added to water or when water is added to said mate ⁇ al, the protective material forms a gel that thickens.
  • polyvalent cations can be present m the protective material and/or in the substrate when water is added to protective mate ⁇ al that has no polyvalent cations present, a gel only forms once the protective mate ⁇ al is in contact with the substrate If there are polyvalent cations present in the protective mate ⁇ al, it can be added to water, a gel formed which can be shaped and worked The resultant mate ⁇ al can be d ⁇ ed, applied to the substrate and, in the presence of and water, forms a mucilaginous gel.
  • the protective material is a carbohydrate compound and is selected from the monovalent alkali salts of carboxypolysaccha ⁇ des.
  • the protective material includes a synthetic polymer, examples of such may include polyamonic polymers, such as sulphonated urea-melamme- formaldehyde and urea-formaldehyde.
  • composition as desc ⁇ bed above in which a mild acid is added to activate the protective material with or without m the presence of polyvalent cations.
  • compositions as described above in which said composition further includes ente ⁇ c coating substances.
  • the enteric coating substances are optionally selected from the group of carbohydrate based material and or any of the group of polymers: fats, fatty acids, waxes, wax mixtures, shellac, ammoniated shellac, cellulose acetate phthalates, the sodium salt of carboxypolysaccha ⁇ de; and a combination of these.
  • Such substances can be used to effect a time span composition, releasing the contents of the composition at a pre-determined time
  • compositions as desc ⁇ bed above in which said composition further includes a compound additive selected from the group, a nutrient, an enzyme, a medication, a biological organism, and a combination of these compounds

  • composition When such a composition is added to water a solution is obtained and is easily applied to the substrate. When the composition is on, for example, leaves it forms a gel after reaction with the expired carbon dioxide. In the soil, where polyvalent cations are present, the mucilage gel is formed.
  • the step of extrusion (step (e)) and selection of tablet size is determined by selection of the size of the extrusion die, and finished length of extruded mate ⁇ al.
  • the tablets may be pill-sized (and so referred to).
  • the step of drying may be by any known process, for example: a drying rotating drum, rotating disc, hot air d ⁇ er or a heated jacket d ⁇ er.
  • the protective mate ⁇ al may be compositions of a single component, or a combination of more than one component, that has gelling properties when in contact with water and polyvalent cations. Many of these protective mate ⁇ als become viscous with water, making an ideal medium for producing a dough. These protective mate ⁇ als, having clathratic properties and gelling capabilities, can be used to produce pills even with polyvalent materials, for m this case, instead of having a viscous formation, a gel is formed. This also aids in dough making.
  • the shape of the pill or tablet is any shape, not just a sphe ⁇ cal shape that has the largest surface area per unit volume compared with other shapes
  • Other mate ⁇ als that need not have clathratic properties, can be added to prepare pills and time release pills These mate ⁇ als delay release of the chemicals enclosed in the pill when water is applied to the pill and the gel is formed
  • a combination of materials with clathratic and non clathratic properties can be use to make pills and time release pills Coatings to ente ⁇ c coated pills can be sprayed onto these pills, giving a first release chem ⁇ cal(s) followed by the ente ⁇ c coated interior as a later time release.
  • the dough when extruded and cut into small particles or compressed to any shape or tablet, will form pills that become hard on drying.
  • the tablets/pills produced in this way can consist of single mate ⁇ al or combinations of more than one material
  • This wholly soluble solution when sprayed on plants or to the soil, forms a gel by coming in contact with polyvalent cations or under the conditions when the pH is reduced by acids from outside the solution (as is the case on the surface of leaves of live plants).
  • the protective mate ⁇ als thus have more than one use; they are used to make the dough for pill manufacture, time-span release, hold caged nut ⁇ ents, they are a gel preventing leaching and fixation, act as a food for soil organisms, and are a soil conditioner.
  • the pills may be designed having polyvalent cations present. These pills can be applied as a solid to the soil such that when water is available the gel is formed
  • the size of the pill is important as very small sized pills have greater surface area per unit volume than larger sized pills If the pill is totally soluble then the smaller the size the more readily the pill will dissolve.
  • the pills made by any combination, one compound or more than one blended together is applied as a solid that forms gels the soil, when water is available. Then the small sized pills will gel in a separate environment, encasing the material within the pill and make the nutrients available to the plant, before the larger pills can and provides protection from leaching and fixation
  • each pill will form its own shape environment gel
  • lime pills and other nutrient pills can be mixed together, as they are then protected from interaction with the other since each pill is protected form interaction with the soil chemicals
  • Numerous varieties of pills can thus be made, with single components, or more than one component, or as a time span pill
  • the selection of the pills of va ⁇ ous types can then be blended together and used as any combination of one or more pills in the blend and applied at the one time to the soil or pasture
  • all mate ⁇ als used as a fertiliser can be applied together without the normal interaction and leaching is minimised or completely prevented depending upon the protective mate ⁇ al/s used and the quantity incorporated m the pill
  • the mate ⁇ als used to make the pills can include hormones, or any other medication, to be available at a time when wanted, once the p ⁇ ll(s) are activated by water
  • the pills can be made with time span coating, or protected by synthetically attaching the active hormone or medication to a prosthetic group, that prevents the action of the medication
  • These medication protected materials can be made into pills that are released by smaller time span pills containing enzymes, within the larger pill that is released at a time calculated and then the enzyme will split off the inactive prosthetic portion from the molecule and make the medication active
  • pills need not be the only method of application
  • a method of prepa ⁇ ng a composition m which fine particles of inorganic, organic, or a combination are blended together with the protective mate ⁇ al (as defined above)
  • This is applied to the substrate as a blended powder, or by application of water and spraying
  • a gel will form when water is available but, not have each component protected by the shape gel formation, interaction will take place by the interaction of compounds monovalent with polyvalent mate ⁇ al if present
  • This interaction can be protected from other interaction by separating the polyvalent mate ⁇ al and applying it separately if in powder form where on the other hand pills combined with pills that normally would react will not now react because of the shape protected environment of each pill
  • each component added makes up a percentage of the nutrients in the final formulation to be applied, for as one nutrient may need to be increased all the others are altered as a percentage
