Abstract

Disclosed herein are fertilizer compositions comprising: a fertilizer comprising a nitrogen compound, a phosphorus compound, and a potassium compound. The fertilizer composition also comprises a filler. Also, disclosed are the methods of making and methods of using the fertilizer compositions.

First claim

1 . A fertilizer composition comprising:
a) a fertilizer comprising a nitrogen compound, a phosphorus compound, a sulfur compound, and one or more potassium compounds, wherein one of the one or more potassium compounds is potassium oxide, and b) a filler, wherein the filler comprises single superphosphate or triple superphosphate or a combination thereof.

2 - 7 . (canceled)

8 . The fertilizer composition of claim 1 , wherein the fertilizer comprises nitrogen in the range of from 10 wt % to 20 wt %; P 2 O 5 in the range of from 10 wt % to 20 wt %; K 2 O in the range of from 5 wt % to 18 wt %; and sulfate in the range of from 5 wt % to 15 wt %.

9 . The fertilizer composition of claim 1 , wherein the fertilizer composition does not comprise potassium chloride or potassium sulfate.

10 . The fertilizer composition of claim 1 , wherein the fertilizer composition comprises an ammoniacal nitrogen source or a nitrate nitrogen source.

11 . The fertilizer composition of claim 10 , wherein the fertilizer composition comprises an ammoniacal nitrogen source that comprises monoammonium phosphate-based ammoniacal nitrogen, diammonium phosphate-based ammoniacal nitrogen, or ammonium sulfate-based ammoniacal nitrogen, or a combination thereof.

12 . The fertilizer composition of claim 1 , wherein the fertilizer composition comprises a phosphate source.

13 . The fertilizer composition of claim 12 , wherein the phosphate source comprises a monoammonium phosphate-based phosphate or diammonium phosphate-based phosphate, or a combination thereof.

14 . The fertilizer composition of claim 1 , wherein the fertilizer composition comprises calcium sulfate or ammonium sulfate or a combination thereof.

15 . The fertilizer composition of claim 1 , comprising:
a) two or more nitrogen compounds, wherein two of the two or more nitrogen compounds are an ammoniacal nitrogen source and a nitrate nitrogen source, b) one or more phosphorus compounds, wherein one of the one or more phosphorus compounds is a phosphate source, c) one or more sulfur compounds, wherein one of the one or more sulfur compounds is calcium sulfate or ammonium sulfate, d) potassium oxide, and e) a filler, wherein the filler comprises single superphosphate or triple superphosphate or a combination thereof.

16 . (canceled)

17 . The fertilizer composition of claim 15 , wherein the sulfur compound is calcium sulfate.

18 . The fertilizer composition of claim 1 , further comprising a micronutrient.

19 . The fertilizer composition of claim 1 , wherein the fertilizer composition does not comprise diammonium phosphate (DAP).

20 . (canceled)

21 . The fertilizer composition of claim 1 , wherein the fertilizer composition does not comprise gypsum.

22 . (canceled)

23 . (canceled)

24 . The fertilizer composition of claim 1 , wherein the fertilizer composition is substantially free of chlorine.

25 . The fertilizer composition of claim 1 , wherein the fertilizer composition comprises a trace element in an amount ranging from 1 wt % to 15 wt % based on the total fertilizer composition, wherein the trace element comprises iron, zinc, copper, or manganese, or a combination thereof.

26 . (canceled)

27 . The fertilizer composition of claim 1 , wherein the single superphosphate or triple superphosphate is different than the phosphorus compound or the one or more phosphorus compounds.

28 - 36 . (canceled)

37 . The fertilizer composition of claim 1 , comprising
monoammonium phosphate-based NPK Grade 12-12-17 fertilizer, diammonium phosphate-based NPK Grade 12-12-17 fertilizer, monoammonium phosphate-based NPK Grade 15-15-15 fertilizer, diammonium phosphate-based NPK Grade 15-15-15 fertilizer, diammonium phosphate-based NPK 16-16-16 Grade fertilizer, or diammonium phosphate-based NPK 18-18-5 Grade fertilizer.

38 . A method for producing a fertilizer composition of claim 1 , wherein the fertilizer composition comprises ammonium sulfate comprising the steps of:
a) supplying a mixture of sulfuric acid and phosphoric acid; and b) adding ammonia and phosphate rock to the mixture, thereby forming single superphosphate or triple superphosphate or a combination thereof and in-situ ammonium sulfate.

39 . (canceled)

40 . The method of claim 38 , wherein the in-situ ammonium sulfate is from 80 wt % to 100 wt % of the ammonium sulfate in the fertilizer composition.

41 . The method of claim 38 , wherein the formation of the in-situ ammonium sulfate generates an amount of heat operable to produce a set of conditions in a granulator to produce a granule with a diameter ranging from 2 mm to 4.5 mm in size.
