An agricultural potassium-fertigation method for emitter-irrigation potassium-plus fertigation feeds a potassium-plus nutrient feedstock comprised of potassium formate and additional yield-assist constituent(s) and water to an active emitter-irrigation system discontinuously, at levels of 0.15 to 50
An agricultural potassium-fertigation method for emitter-irrigation potassium-plus fertigation feeds a potassium-plus nutrient feedstock comprised of potassium formate and additional yield-assist constituent(s) and water to an active emitter-irrigation system discontinuously, at levels of 0.15 to 50 gal./min, during one to six nonconsecutive irrigation days during a crop cycle.

1. A method of fertigation of an agricultural field, comprising: charging a feedstock to a stream of flowing irrigation water upstream of said agricultural field to convert said irrigation water to treated irrigation water, wherein said feedstock (i) comprises from 5 to 35 wt. percent potassium form
1. A method of fertigation of an agricultural field, comprising: charging a feedstock to a stream of flowing irrigation water upstream of said agricultural field to convert said irrigation water to treated irrigation water, wherein said feedstock (i) comprises from 5 to 35 wt. percent potassium formate, from 5 to 35 wt. percent additional yield-assist constituent(s) and water, and (ii) is present in said treated irrigation water at a level providing from 50 to 10,000 ppm of potassium as K2O and from 100 to 7,500 ppm of said additional yield-assist constituent(s); andirrigating said agricultural field with said treated irrigation water. 2. The method of claim 1, further comprising repeating the method on 1 to 5 nonconsecutive irrigation days over a crop cycle. 3. The method of claim 2, wherein said feedstock is charged from 1 to 9 hours during an irrigation day. 4. The method of claim 1, wherein said additional yield-assist constituent(s) are selected from the group consisting of N (as N), P (as P2O5), Zn, Cu, Fe, Mn, acid and combinations thereof. 5. The method of claim 1, wherein said agricultural field is irrigated using an emitter-irrigation system. 6. The method of claim 5, wherein said emitter-irrigation system comprises a micro-irrigation system or an overhead sprinkler system. 7. The method of claim 5, wherein said feedstock is charged to said emitter-irrigation system by feeding it to the irrigation water flowing through a main line of said emitter-irrigation system downstream of any filters in said emitter-irrigation system and upstream of all delivery points of said emitter-irrigation system. 8. The method of claim 1, wherein said feedstock is charged at a rate of 0.15 to 50 gal./min. 9. A treated irrigation water, comprising irrigation water and a feedstock, wherein said feedstock comprises potassium formate and one or more additional yield-assist constituents, and is present in said irrigation water at a level providing from 50 to 10,000 ppm of potassium as K2O and from 100 to 7,500 ppm of said additional yield-assist constituent(s). 10. The treated irrigation water of claim 9, wherein said additional yield-assist constituent(s) are selected from the group consisting of N (as N), P (as P2O5), Zn, Cu, Fe, Mn, acid and combinations thereof. 11. The treated irrigation water of claim 9, wherein said additional yield-assist constituent(s) are selected from the group consisting of urea, EDTA or a salt thereof, aminotris(methylenephosphonic acid) (ATMP), ammonia, ammonium nitrate, di-ammonium phosphate, phosphoric acid, and formic acid. 12. The treated irrigation water of claim 11, wherein from 90 to 100 weight percent of said additional yield-assist constituent(s) are selected from said group. 13. The method of claim 1, wherein said feedstock comprises EDTA or a zinc, copper, iron or manganese salt thereof. 14. The method of claim 1, wherein said feedstock comprises from 10 to 20 wt. percent potassium formate and from 5 to 20 wt. percent said additional yield-assist constituent(s).
