“…The roots were stubby and club-like with swellings, particularly just behind the root tips, compared with the normal more fibrous root system of plants with 0 to 3 ppm of N-Serve. The effects of N-Serve on the growth of the shoots and roots of soybeans were very similar to those described previously for alfalfa (4) and black locust (3,6).…”

Soybeans were grown for 18 days in a silt loam soil containing 0 to 20 ppm 2‐chloro‐6‐(trichloromethyl) pyridine (N‐Serve). Yield of shoots was reduced by concentrations of 8 and 20 ppm and their morphology was altered with concentrations as low as 1 ppm. Yield of roots was not greatly affected by up to 20 ppm, but their morphology was drastically altered with 8 and 20 ppm. Production of NO3 in the soil was reduced 90% by 8 and 20 ppm, 60% by 3 ppm and only slightly by 1 and 0.5 ppm of 2‐chloro‐6‐(trichloromethyl) pyridine.

“…There are indications that nitrapyrin may be more effective in controlling nitrification in soils with higher clay contents than in soils with lower clay contents (Bundy and Bremner, 1973). Some authors (Geronimo et al, 1973;Goring, 1962;Prasad, 1976;Rieck and Lynd, 1967;Touchton et al, 1978a) have reported differences in nitrification or crop response among soils with various pH values when equal rates of N and nitrapyrin were applied to each soil. However, with one exception, soil pH was not the primary variable investigated, and the difference in nitrification or crop response among soils was generally not attributed to the possible effect of pH on the loss of nitrapyrin from the soil.…”

Little information is available on soil characteristics that influence the persistence of nitrapyrin [2‐chloro‐6‐(trichloromethyl) pyridine] in soil. Knowledge concerning these characteristics could be helpful in determining the most effective time of nitrapyrin application and in identifying soils in which the most effective inhibition of nitrification by nitrapyrin might be expected. The objective of this study was to evaluate the effects of soil pH and temperature on the disappearance of nitrapyrin and ammonium‐N from the soil. Nitrapyrin was applied at rates of 2 and 4 ppm to three soils with pH levels adjusted to approximately 5.5, 6.3, and 6.8. In two of the three soils, the rate of nitrapyrin disappearance increased with increasing pH levels. However, nitrapyrin concentrations in the soil at the end of the 83‐day incubation period were equal among pH levels. When pH influenced nitrapyrin disappearance, recoverable nitrapyrin decreased curvilinearly with time. When pH had no apparent effect on nitrapyrin, recoverable nitrapyrin decreased linearly with time. In the temperature study, nitrapyrin and N were applied to Drummer (Typic Haplaquoll) and Cisne (Mollic Albaqualf) soils and incubated for 154 days at temperatures of 4, 13, and 21 C. Disappearance of nitrapyrin and ammonium‐N occurred at all temperatures and increased with increasing temperatures. The half life of nitrapyrin in the Cisne soil was 22 days when incubated at 4 C, and less than 7 days when incubated at 13 and 21 C. The half life of nitrapyrin in the Drummer soil was 92, 44, and 22 days, when incubated at temperatures of 4, 13, and 21 C, respectively. At all temperatures nitrapyrin was more effective in controlling loss of ammonium in the Drummer than in the Cisne soil.

Nitrification inhibitors were evaluated for their capacity to retard oxidation of ammonium in a pine bark medium. Nitrapyrin, captan, etridiazole, and metalaxyl were added to a pine bark medium in amounts ranging from none to 133% of manufacturers' or research-based recommendations. Inhibition of nitrification was assessed by measurements of appearance of nitrate and disappearance of ammonium at 4-wk intervals for 12 wk. The effects of these chemicals on the growth and nitrogen (N) composition of privet (Ligustrum ibolium L.) in containers of pine bark mix were assessed. Based on retention of ammonium and suppression of nitrate accumulation, etridiazole and nitrapyrin JOURNAL OF PLANT NUTRITION, 25(1), 159-168 (2002) 159 ORDER REPRINTS were effective inhibitors, whereas captan and metalaxyl were not. Etridiazole was more effective than nitrapyrin, and the efficacy of etridiazole increased as amount of application increased. The efficacy lasted for about 4 wk with nitrapyrin or etridiazole. With the amounts of fertilization and inhibitors used, growth or total N concentration of privet was not affected by the inhibitors.
