Definitions

  • the present invention is broadly concerned with dual-component fertilizer materials and methods of use thereof wherein the fertilizer material provides enhanced yields of crops. More particularly, the present invention is concerned with such fertilizer materials comprising a first fertilizer product including an ammoniacal fertilizer and a partial calcium salt of a copolymer, along with a second fertilizer product including a phosphorous fertilizer and a partial sodium salt of a copolymer; the first and second fertilizer products are used in synergistically effective amounts in order to increase crop yields.
  • Fertilizers have included manure products as well as ammoniacal nitrogen materials (e.g., anhydrous ammonia and urea), and phosphorous fertilizers such as ammonium polyphosphate and other products derived from phosphate rock.
  • ammoniacal nitrogen materials e.g., anhydrous ammonia and urea
  • phosphorous fertilizers such as ammonium polyphosphate and other products derived from phosphate rock.
  • a worldwide industry provides modern-day fertilizers of desired N-P-K grades in a bewildering variety of combinations.
  • U.S. Pat. No. 6,515,090 describes dicarboxylic copolymers made up, e.g., of moieties of itaconic acid and maleic anhydride. This patent also discloses that such copolymers may be partially neutralized with metal or other cations, and can be used to form composite products with fertilizers. These combined fertilizer-copolymer products have been shown to increase the availability of phosphorous for uptake by growing plants, and can be applied to soil adjacent the plants or in foliar applications. Polymers in accordance with the '090 patent are commercially available from Specialty Fertilizer Products of Belton, Mo. under the designations NUTRISPHERE-N® and AVAIL®.
  • the present invention is predicated upon the discovery that multiple-component fertilizer materials can be provided which give synergistically enhanced crop yields.
  • Such fertilizer materials broadly include a first fertilizer product including an ammoniacal fertilizer and a partial calcium salt of a first copolymer, and a second fertilizer product including a phosphorous fertilizer and a partial sodium salt of a second copolymer.
  • These fertilizer products are present in synergistically effective amounts for a particular crop.
  • the preferred copolymers are of the type described in U.S. Pat. No. 6,515,090, which is incorporated by reference herein.
  • the first fertilizer product includes a conventional fertilizer such as urea in combination with an aqueous dispersion of a partial calcium salt of a copolymer made up of substantially equimolar amounts of itaconic acid and maleic anhydride moieties and having a pH on the order of 1-5.
  • the second fertilizer product includes a fertilizer such as diammonium phosphate (DAP) or liquid polyammonium phosphate in combination with a partial sodium salt of the same copolymer.
  • DAP diammonium phosphate
  • liquid polyammonium phosphate liquid polyammonium phosphate
  • the preferred methods of the invention comprise the steps of fertilizing by application to soil and/or plants of a fertilizer material comprising synergistically effective amounts of respective first and second fertilizer products.
  • the first fertilizer product is a blend of an ammoniacal fertilizer with a minor amount of a partial calcium salt of one or more copolymers of a selected class thereof, while the second fertilizer product is a blend of a phosphorous fertilizer and a partial sodium salt of one or more of the copolymer class.
  • “Synergistically effective amounts” of the first and second fertilizer products refers to coordinated amounts of each of the fertilizer products which in combination give an increased crop yield in excess of the crop yield which could be obtained by individual application of the first and second fertilizer products in those amounts; stated otherwise, the coordinated amounts of the first and second fertilizer products give crop yields greater than a mere additive effect obtainable through the use of the respective fertilizer products alone in the same amounts. It will be appreciated that the synergistically effective amounts of the first and second fertilizer products are directed to particular crops, and that, depending upon the crop in question, soil conditions, ambient weather, and other factors, the first fertilizer product may be present in a greater amount as compared with the second fertilizer product, or vice versa.
  • the first ammoniacal fertilizer product is usually present in an amount of from about 30-200 lbs. N/acre, and more preferably from about 50-150 lbs. N/acre.
  • the second phosphorous fertilizer product is usually present in a lesser amount as compared with the first ammoniacal fertilizer product and generally from about 10-80 lbs. P2O05/acre, more preferably from about 20-50 lbs. P2O5/acre.
  • the first fertilizer product includes an ammoniacal fertilizer. Any one of the number of such fertilizers may be used in this context.
  • exemplary ammoniacal fertilizers include ammoniacal nitrogen-containing fertilizer, such as those selected from the group consisting of ammonia, ammonium nitrate, ammonium sulfate, urea, monoammonium phosphate, diammonium phosphate, sodium nitrate, calcium nitrate, potassium nitrate, nitrate of soda, urea formaldehyde, methyl ammonium phosphate, ammoniated super phosphate, and mixtures thereof.
  • the fertilizer is preferably in solid or liquid form, with the most preferred fertilizer being granular urea.
  • the copolymer fraction of the first fertilizer product comprises a partial calcium salt of one or more members of a class of copolymers including recurring polymeric subunits each made up of at least two different moieties individually and respectively taken from the group consisting of A, B, and C moieties, or recurring C moieties, and C moieties which are not different, wherein moiety A is of the general formula
  • R 1 , R 2 and R 7 are individually and respectively selected from the group consisting of H, OH, C 1 -C 30 straight, branched chain and cyclic alkyl or aryl groups, C 1 -C 30 straight, branched chain and cyclic alkyl or aryl C 1 -C 30 based ester groups (formate (C 0 ), acetate (C 1 ), propionate (C 2 ), butyrate (C 3 ), etc.
  • R′ is selected from the group consisting of C 1 -C 30 straight, branched chain and cyclic alkyl or aryl groups
  • R 3 and R 4 are individually and respectively selected from the group consisting of H, C 1 -C 30 straight, branched chain and cyclic alkyl or aryl groups
  • R 5 , R 6 , R 10 , and R 11 are individually and respectively selected from the group consisting of H, the alkali metals, NH 4 and the C 1 -C 4 alkyl ammonium groups
  • Y is selected from the group consisting of Fe, Mn, Mg, Zn, Cu, Ni, Co, Mo, V, Cr, Si, B, and Ca
  • R 8 , and R 9 are individually and respectively selected from the group consisting of nothing, CH 2 , C 2 H 4 , and C 3 H 6 .
  • At least one of the R 3 , R 2 and R 7 groups is OH where the polymeric subunits are made up of A and C moieties, and at least one of the R 1 , R 2 , R 3 , R 4 , and R 7 groups is OH where the polymeric subunits are made up of A, B and C moieties
  • the more preferred class of polymers have the generalized formula
  • X is a cation and p ranges from about 10-500. At least some of the X substituents are calcium, whereas others may be different metal cations (e.g., alkali and alkaline earth metal cations), and some are H. Thus, the copolymers exist as a partial salt or complex.
  • the first fertilizer product may be formed by any convenient means of mixing of the fertilizer and polymer fractions.
  • the polymer is most conveniently applied by spraying or dipping.
  • the copolymer is usually mixed into the liquid with appropriate stirring.
  • the first fertilizer product copolymer fraction is normally an aqueous liquid product having a solids content of from about 20-80% by weight, more preferably from about 30-50% by weight, and a pH of from about 1-5, more preferably from about 2-3.5.
  • the second fertilizer product includes a phosphorous fertilizer, such as monoammonium phosphate (MAP), diammonium phosphate (DAP), calcium phosphates (normal phosphate and super phosphate), ammonium phosphate, ammonium super phosphate, ammonium polyphosphate, phosphoric acid, basic slag, rock phosphate, colloidal phosphate, bone phosphate, ammonium sulfate, ammonium thiosulfate, and mixtures thereof.

  • the levels of copolymer use for the first and second fertilizer products are substantially the same.
  • the copolymer salts in each case should normally be present in the first and second fertilizer products at a level of from about 0.01-2.0% by volume, and more preferably from about 0.1-0.5% by volume, based upon the total volume of the respective fertilizer product taken as 100% by volume.
  • the first and second fertilizer products can be used in various ways, so long as both products are present on or about plants or the soil adjacent plants.
  • the fertilizer products can be separately formulated and applied to soil or plants substantially simultaneously or in serial order.
  • the first and second fertilizer products can be blended together and applied in that condition.
  • the products can be applied by spreading or broadcast.
