Abstract
The invention provides compositions, systems and methods for controlling loss of nutrients and other substances from planting sites.
Claims20
A composition for use at a crop planting site, the composition comprising:
- a specific ion complexing agent (SICA) coupled to a substrate via a linker molecule;
- wherein said SICA forms a coordination complex with, and reversibly retains, a desired compound;
- wherein the SICA is selected from the group consisting of 1,10-diaza-4,7,13,16,21,24-hexaoxabicyclo[8.8.8]hexacosane, 1,5-diazabicyclo[4.3.0]non-5-ene, 3,6,9, 17,20,23-hexaazatricyclo[23.3.1.111,15]-triaconta-1(29),11,13,15(30),25,27-hexaene, and 7-[2-Hydroxy-3-(4-phenylpiperazin-1-yl)-propyl]-1,3-dimethyl-8-(2-morpholin-4-ylethylamino)-3,7-dihydropurine-2,6-dione;
- and,
- wherein said desired compound is selected from the group consisting of a nitrate, nitrite, ammonium, phosphate, sulfate, and combinations thereof.

A composition for use at a crop planting site, the composition comprising:
- a specific ion complexing agent (SICA) coupled to a substrate via at least one linker molecule;
- wherein said SICA forms a coordination complex with, and reversibly retains, a desired compound;
- wherein the SICA is selected from the group consisting of 1,10-diaza-4,7,13,16,21,24-hexaoxabicyclo[8.8.8]hexacosane, 1,5-diazabicyclo[4.3.0]non-5-ene, 3,6,9, 17,20,23-hexaazatricyclo[23.3.1.111,15]-triaconta-1(29),11,13,15(30),25,27-hexaene, and 7-[2-Hydroxy-3-(4-phenylpiperazin-1-yl)-propyl]-1,3-dimethyl-8-(2-morpholin-4-ylethylamino)-3,7-dihydropurine-2,6-dione;
- and,
- wherein said desired compound is selected from the group consisting of a nitrate, nitrite, ammonium, phosphate, sulfate, and combinations thereof.
2 more elements
A composition that reduces the loss of a desired compound from a planting site, the composition comprising:
- a substrate coupled to a specific ion complexing agent (SICA), wherein said SICA is coupled to said substrate with a functional group of the substrate, and wherein the substrate is modified to comprise the functional group;
- wherein said SICA forms a coordination complex with a desired compound;
- wherein the SICA is selected from the group consisting of 1,10-diaza-4,7,13,16,21,24-hexaoxabicyclo[8.8.8]hexacosane, 1,5-diazabicyclo[4.3.0]non-5-ene, 3,6,9, 17,20,23-hexaazatricyclo[23.3.1.111,15]-triaconta-1(29),11,13,15(30),25,27-hexaene, and 7-[2-Hydroxy-3-(4-phenylpiperazin-1-yl)-propyl]-1,3-dimethyl-8-(2-morpholin-4-ylethylamino)-3,7-dihydropurine-2,6-dione;
- and,
- wherein said desired compound is selected from the group consisting of a nitrate, nitrite, ammonium, phosphate, sulfate, and combinations thereof.
