“…This trend was generally consistent across ACA rates (data not shown). The influence on harvested tuber size suggests that the additive may be functioning as a plant-growth regulator, as was suggested by some of the early research with other crops and some visual observations that indicated the plant metabolism may have been affected (Thasanasongchan 1981). Other soil or plant additives including a microbial culture (Wolkowski and Kelling 1984) and daminozide (Sanderson et al 1990;Mitkitzel 1995) have also resulted in changes in tuber size distributions.…”

Over a 5-year period, field evaluations of several rates of ACA, an acronym for Agricultural Crop Additive, were conducted on irrigated sandy Wisconsin soils using potato (Solanum tuberosum L.) as the test crop. In some years, statistically significant tuber total yield increases of about 4 Mg ha −1 were seen for one rate, but not others, with the response rate varying between years. In 1 year, similarly sized yield increases were seen for all rates. In most years, the use of ACA (at one or more rates) increased the size of harvested tubers but did not affect other measured growth parameters including stem or tuber number, early-season vegetative or root growth, or midseason leaf nutrient concentrations. In the year when ACA was evaluated across three potato varieties, the responses appeared to be variety specific. No clear mode of action could be identified where the positive responses were seen other than the apparent influence of the additive on harvested tuber size.

“…availability of Zn to plants is influenced by the presence of organic ligands and that Zn adsorption by soil decreases in the presence of acetate (Chairidchai and Ritchie, 1990). The ZAA molecule, which contains 33% zinc acetate, has been suggested to be an organic Zn chelate by which the fixation of Zn is reduced and Zn uptake by plants is enhanced (Ott, 1982;Thasanasongchan, 1981). In addition, ZAA contains five NH + 4 groups chemically.…”

Fate of Zinc Ammonia Acetate in Soils and Its Uptake by Corn

Zinc ammonium acetate (ZAA) is applied to soil with anhydrous ammonia as a carrier to improve corn (Zea mays L.) productivity. To study the fate of ZAA in the soils, a laboratory leaching experiment was conducted with 14 C-ZAA and 65 Zn-ZAA using water or NH 4 OH as carrier. Results showed that ZAA degraded in the soil and released CO 2 . The released CO 2 was from the acetate component of ZAA and accounted for less than 0.06% of the total applied 14 C. Using H 2 O as carrier resulted in more CO 2 release than using NH 4 OH, regardless of soil type. However, more 14 C was detected in the leachate when using NH 4 OH as a carrier than when using H 2 O. A plant uptake experiment using 14 C-ZAA and 65 Zn-ZAA indicated that four-leaf-stage corn seedlings absorbed higher amounts of 14 C in the stem and root than in the leaves. The 65 Zn was detected in most tested plant parts. Our study showed that ZAA enhanced cytokinin levels in root and/or shoot tissues of corn seedlings, suggesting a secondary regulatory effect of ZAA in improving corn productivity.

“…Low concentrations of ZAA (µl/L level) have also increased plant height, leaf area, and shoot and root dry weight of corn seedlings (Liu et al, 1997). The literature suggests that ammonium acetate (Ott, 1982;Thasnaasongchan, 1981), zinc (Zn) (Khosravi, 1980;Ott, 1974Ott, , 1975Ott, , 1976Thasnaasongchan, 1981), or acetate (Ott, 1982;Thasnaasongchan, 1981) could be directly involved with stimulation of plant growth after it is applied in the soil. However, the fate of ZAA in soils and the determination of the effective components of ZAA have been critical concerns for both researchers and farmers.…”

“…The chemical, which is formulated by combining acetic acid, water, anhydrous ammonia, and zinc oxide in a patented procedure (Ott, 1974), has been reported to increase the grain yield of corn (Zea mays L.) as a result of increased weight per kernel (Thasnaasongchan, 1981;Khosravi, 1980;Oplinger, 1990). Low concentrations of ZAA (µl/L level) have also increased plant height, leaf area, and shoot and root dry weight of corn seedlings (Liu et al, 1997).…”

Zinc ammonium acetate (ZAA), typically applied to soils in anhydrous ammonia as a carrier, has been used to improve corn (Zea mays L.) productivity. This study aimed to determine the fate of ZAA in soils as influenced by soil type (sandy, silt, and clay loam), sterilization (sterile and non-sterile), and two carriers (H 2 O and NH 4 OH). A 16 d laboratory incubation experiment with 14 C-ZAA showed that total recovery of carbon-14 ( 14 C) from 14 CO 2 trap and soil extraction by CaCl 2 ranged from 72% to 94% in the first 8 d for sterilized soils. However, <17% 14 C was found in non-sterilized soils. Most 14 C recovered in sterilized soil was associated with soil extraction, and relatively little was found in the CO 2 traps. All sterilized soils provided similar 14 C recoveries except the sandy loam. Slightly more 14 C was extracted from the soil when NH 4 OH was the ZAA carrier rather than water. Conversely, recovery of 14 CO 2 continued to increase during the 16 d incubation, but started faster when water was the ZAA carrier. Microbial activity appeared to be instrumental in the assimilation and disappearance of ZAA.
