Preferably, the water-retentive product is in the form of granules of polyacrylamide, which swell in water to a number of times their size when dry. The granules absorb the liquid very quickly but release it only slowly, so that they can swell and dry over and over and so have a long effective life.

  • Patent number: 5472475
    Abstract: To make an artificial topsoil combine by hand or in a blending machine, by volume, either dredged river silt, sand or basalt, and cellulose from recycled paper or yard waste, with composted animal or human waste for general reclamation and cereal crops, or vegetable or fruit residuals for gardens or potting soil, and then add calcium in the form of calcium silicate as slag or lime and ammonium nitrate or sulfate mixed with water, and then charcoal or equivalent amount of phosphorus, sodium, and sulfur as are present in charcoal. This combination of material replicates the calcium base, decaying cellulose, silt and animal or vegetable waste structure of natural soils.Various soil types can be duplicated by adjusting the base content of sand, silt, or basalt and rearranging the nutrient and mineral content to compensate for differing levels of each, for example: calcium and organic percentages should be increased to maximum when using sand as a base.

  • Patent number: 5451242
    Abstract: A synthetic soil/fertilizer for horticultural application having all the agronutrients essential for plant growth is disclosed. The soil comprises a synthetic apatite fertilizer having sulfur, magnesium and micronutrients dispersed in a calcium phosphate matrix, a zeolite cation exchange medium saturated with a charge of potassium and nitrogen cations, and an optional pH buffer. Moisture dissolves the apatite and mobilizes the nutrient elements from the apatite matrix and the zeolite charge sites.

  • Patent number: 5443612
    Abstract: Methods of making agricultural materials for aiding and facilitating the growth of plants and crops are based on the combination of waste paper and other materials and the formation of such combinations into pellets. Where the agricultural material is for use in the casing layer of a mushroom tray, the agricultural material is made from a combination of waste paper and a pH adjusting material, which is preferably lime. Where the agricultural material is for general use in agricultural and horticultural applications, it is made from a combination of waste paper and compost material, the ratio of the compost used in the combination being between about 90% to 40% by weight.

  • Patent number: 5405426
    Abstract: Extended residual, controlled release sulfur coated fertilizers having polymeric topcoats applied over a sulfur coating layer are prepared wherein the sulfur coating contains a sufficient amount of a crystalline sulfur allotrope in combination with at least a minimal level of carbon disulfide insoluble amorphous sulfur to maintain the sulfur coating in a pliable, resilient condition at the time at which the polymeric topcoat is applied over the sulfur coating. The presence of such sulfur allotrope is demonstrated by a shoulder endotherm appearing on a differential scanning calorimetry thermogram within a transition temperature range of about 84.degree. C.-97.degree. C.

  • Patent number: 5395419
    Abstract: Disclosed is the use of oxygen delivery vehicles, including peroxides of calcium, potassium and magnesium, to treat plant media having a negative reduction oxidation potential. The peroxides are preferably intercalated with phosphate ion which prolongs the period of time during which oxygen is released. The peroxides may be mixed with macronutrients, micronutrients or other beneficial additives or amendments, to provide fertilizers or applied direct to the media. Effective amounts of metals are used as bioactive agents for suppressing or enhancing the activity of microorganisms in the soil, depending on whether such microorganisms are detrimental or beneficial to plants. The formulations are useful in treating anaerobic associated disease states such as black layer in turf. The formulations are also useful in controlling post harvest potato soft rot and other microbial infection and disease states in plants.

  • Patent number: 5350435
    Abstract: The present invention provides a soil fertilization method which includes a process for producing a fertilyzer by-product from an ammonia filtering media. The method includes the steps of providing a filter media containing phosphoric acid soaked particles. In addition, the method includes providing ammonia laden air. The ammonia laden air is passed through the filter media to remove ammonia from the air which is removed by a chemical reaction which converts the phosphoric acid soaked wood particles to ammonium phosphate coated wood particles. After substantially all of the wood particles are converted to ammonium phosphate wood particles, the filter media is collected and then applied to soil to fertilize and build the soil.

  • Patent number: 5266097
    Abstract: A new method of preparing a new aminoureaformaldehyde fertilizer composition which exhibits high cold water insoluble nitrogen (CWIN) levels and high Availability Indices (AI). The method utilizes the discoveries that ammonia compounds, usually ammonium salts, inhibit the urea-formaldehyde polymerization reaction and decrease the formation of hot water insoluble nitrogen (HWIN), and that the ammonium compounds take part in the reaction to form controlled release compounds which are both cold water soluble and insoluble. The process is carried out at elevated temperatures between 60 and 125.degree. F., so that it may be completed in an order of magnitude less time than either the dilute or concentrated conventional commercial ureaform processes, requiring between 2 and 20 minutes for completion. In the process, between 3 and 25 percent of the total nitrogen is supplied as ammonia nitrogen with the remainder from urea, respective formaldehyde to urea to ammonia mol ratio is 1.0, between 1.0 and 2.
