Abstract
A method of enhancing soil water infiltration (SWI) and/or reducing soil water repellency (SWR) comprising: treating an area of groundcover with a composition A comprising A1) a block polymer (P) comprising at least one polyethyleneoxide moiety and at least one polypropyleneoxide moiety, and A2) an alcohol alkoxylate (E), wherein the SWI of the area of groundcover is enhanced and/or the SWR of the area of groundcover is reduced after treatment with the composition A.
Claims15
1-16. (canceled)
A method of enhancing soil water infiltration (SWI) and/or reducing soil water repellency (SWR) comprising:
- treating an area of groundcover with a composition (composition A) comprising
- A1) a block polymer (P) comprising at least one polyethyleneoxide moiety and at least one polypropyleneoxide moiety, and
- A2) an alcohol alkoxylate (E),
- wherein the SWI of the area of groundcover is enhanced and/or the SWR of the area of groundcover is reduced after treatment with the composition A.
A method of enhancing soil water infiltration (SWI) and/or reducing soil water repellency (SWR) comprising:
- treating an area of groundcover with a composition (composition B) comprising
- B1) an alcohol ethoxylate (L) of the general formula (III)
- R3—O—(C2H4O)s—H (III)
- wherein R3 is branched C8 to C20 alkyl, and
- s has a value of from 1 to 40,
- and
- B2) an alcohol alkoxylate (E),
- wherein the SWI of the area of groundcover is enhanced and/or the SWR of the area of groundcover is reduced after treatment with the composition B.
A method according to claim 30,
- wherein the alcohol alkoxylate (E) is selected among alcohol alkoxylates of the formula (I), in which R is branched C5-C30-alkyl, m is 2, x is from 5.0 to 5.5, n=3, y is from 4.5 to 5, p=2, and z is from 2 to 2.5, and
- the alcohol ethoxylate (L) is selected among alcohol alkoxylates of the formula (III), in which R3 is isotridecyl and s is from 7 to 9.
