Claims21
A method for reducing loss of a desired compound from a planting site due to runoff, ground water, evaporation or windage, comprising:
- providing a specific ion complexing agent (SICA) composition to the planting site having the desired compound, wherein said SICA composition includes a specific ion complexing agent (SICA) and a substrate coupled to the SICA, and wherein said SICA forms a coordination complex with, and reversibly retains the desired compound,
- wherein the SICA is selected from the group consisting of 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.
A method of increasing crop yield, comprising:
- providing a specific ion complexing agent (SICA) composition to a planting media used for growing a crop to retain a desired compound in the plant media, wherein said SICA composition includes a specific ion complexing agent and a substrate coupled to the SICA, and where said SICA forms a coordination complex, and reversibly retains the desired compound in the plant media,
- wherein the SICA is selected from the group consisting of 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.
A method for reducing loss of a desired compound from a planting site due to runoff, ground water, evaporation or windage, comprising:
- providing a specific ion complexing agent (SICA) composition to the planting site having the desired compound, wherein said SICA composition includes a specific ion complexing agent (SICA) and a substrate covalently linked to the SICA via a linker, and wherein said SICA forms a coordination complex with, and reversibly retains the 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 the linker is formed by N-β-maleimidopropionic acid hydrazide (BMPH), 1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride, sodium meta-periodiate, or cyanoborohydride.
A method of increasing crop yield, comprising:
- providing a specific ion complexing agent (SICA) composition to a planting media used for growing a crop to retain a desired compound in the plant media, wherein said SICA composition includes a specific ion complexing agent and a substrate covalently linked to the SICA via a linker, and where said SICA forms a coordination complex, and reversibly retains the desired compound in the plant media,
- 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 the linker is formed by N-β-maleimidopropionic acid hydrazide (BMPH), 1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride, sodium meta-periodiate, or cyanoborohydride.
