FERTILIZER COMPOSITION INCLUDING ANIMAL MANURE AND CEMENTITIOUS MATERIALS
A composition for use as fertilizer includes cement kiln dust or fly ash and animal manure. The content of cement kiln dust or fly ash and animal manure in the composition is selected as a function of either weight or volume. The content of cement kiln dust or fly ash is greater than or equal to the content of animal manure. The fertilizer composition is formed by mixing the cement kiln dust or fly ash and animal manure at ambient temperature and pressure.
1 . A fertilizer composition comprising:
cement kiln dust or fly ash; and
animal manure, wherein a weight percent of the cement kiln dust in the fertilizer composition is greater than or equal to a weight percent of the animal manure in the fertilizer composition and/or wherein a volume of the cement kiln dust in the fertilizer composition is greater than or equal to a volume of the animal manure in the fertilizer composition.
2 . The fertilizer composition of claim 1 , wherein the weight percent of cement kiln dust or fly ash is in a range from 50% and 70%, inclusive, and wherein a remainder of the composition is the animal manure.
3 . The fertilizer composition of claim 1 , wherein a ratio of the volume of the cement kiln dust or fly ash to the volume of animal manure is in a range from 1:1 to 3:1, inclusive.
4 . The fertilizer composition of claim 1 , wherein a pH of the fertilizer composition is in a range from 11 to 13, preferably from 12 to 13, inclusive.
5 . The fertilizer composition of claim 1 , wherein the animal manure comprises liquid cow manure.
6 . The fertilizer composition of claim 1 , wherein the mixture consists of cement kiln dust or fly ash and animal manure.
7 . A method comprising:
mixing cement kiln dust or fly ash with animal manure, to form a fertilizer;
drying the mixture; and
distributing the dry mixture over agricultural soil.
8 . The method of claim 7 , wherein cement kiln dust or fly ash and animal manure are mixed at ambient temperature and ambient pressure.
9 . The method of claim 7 , comprising mixing a volume of cement kiln dust or fly ash with a volume of animal manure to form a fertilizer
10 . The method of claim 7 , wherein the volume of cement kiln dust or fly ash is equal to or greater than the volume of animal manure.
11 . The method of claim 10 , wherein a ratio of the volume of the cement kiln dust or fly ash to the volume of animal manure is in a range from 1:1 to 3:1, inclusive.
12 . The method of claim 7 , comprising mixing cement kiln dust or fly ash with animal manure to form a mixture, wherein a weight percent of the cement kiln dust or fly ash in the mixture is greater than or equal to a weight percent of the animal manure in the mixture.
13 . The method of claim 12 , wherein the weight percent of cement kiln dust or fly ash is in a range from 50% and 70%, inclusive, and wherein a remainder of the composition is the animal manure.
14 . The method of claim 7 , wherein the mixture is dried to form a fertilizer composition having pH in a range from 11 to 13 inclusive.
15 . The method of claim 7 , wherein the mixture consists of cement kiln dust or fly ash and animal manure.
