“…Assessment of the relative contribution of inorganic forms of N to the nutrition of soil-grown plants has been based on an equivocal comparison of response to nitrate and inhibitor-treated and untreated ammonium fertilizers either unlabelled (e.g. Goh and Young, 1975;Lewis and Stefanson, 1975) or labelled with 15N (e.g. Gasser et al, 1967;Kowalenko and Cameron, 1978).…”

Rates of N uptake by spring wheat as ammonium and as nitrate, and rates of nitrification, gross N immobilization and gross N mineralization were measured in a pot experiment during 84 days of growth in a clay soil. Soil treatments included an unfertilized control and addition of 15NH4NO 3 or NHn~SNO3 in the absence and presence of N-serve 24E.Incorporation of ammonium into the soil organic N pool was considerably higher in the presence compared to the absence of nitrapyrin, but the processes contributing to this effect could not be positively identified. Both dry matter and grain yield as well as N uptake by wheat were enhanced in the presence of the inhibitor in N fertilized soil, despite the increased immobilization of N. On the other hand, inhibitor application had a detrimental effect on yield and N uptake by wheat in unfertilized soil.Both ammonium and nitrate forms of inorganic N were absorbed by wheat, but nitrate uptake was dominant in the absence of the inhibitor. The uptake of N as ammonium was higher and the uptake of N as nitrate was less, both in absolute and proportional terms, in the presence compared to the absence of inhibitor. In addition, the proportion of N taken up as ammonium was higher than the proportion of N as ammonium in the available N pool up to day 56 in the inhibitor treatment, which indicated a preference for ammonium uptake by wheat.Evidence was obtained which suggested that several factors may have contributed to the positive response of wheat to inhibitor application in N fertilized soil, including reduced N losses, higher gross N mineralization and a physiological response due to the proportional increase in uptake of inorganic N as ammonium.

“…The effectiveness of nitrapyrin at decreasing nitrification in soil depends on a number of interacting factors besides soil temperature (Slangen and Kerkhoff, 1984). Soil OM both absorbs nitrapyrin and provides an energy source for the microorganisms which degrade nitrapyrin, decreasing the ability of nitrapyrin to inhibit nitrification (Goring, 1962;Lewis and Stefanson, 1975). Semi-arid soils often have low OM contents due to the seasonally dry climate, low plant productivity and continual soil loss by erosion (Archibold, 1995;Ryan, 2011).…”

“…The Canisteo soil, having higher organic C content than the Nicollet soil, had the highest NO 3 2 -N accumulation. It is indicated by Bundy and Bremner (1973) and Lewis and Stefanson (1975) that the effectiveness of this compound decreases with increasing inorganic matter. Organic matter is known as a major sorbing component of nitrapyrin (Hendrickson and Keeney 1978).…”

The effects of temperature and water potential on nitrification were investigated in two Iowa soils treated with Stay-N 2000. The soils were incubated at 10, 20, and 30 uC after soil water potentials of 21, 210, or 260 kPa were applied to each soil. A first-order equation was used to calculate the maximum nitrification rate (K max ), duration of lag period (t9), period of maximum nitrification (Dt), and termination period of nitrification (t s ). The highest K max were 18 and 24 mg kg 21 d 21 nitrate (NO 3 2 )-nitrogen (N), respectively, at 30 uC and 210 kPa in both the Nicollet (fine-loamy, mixed, superactive, mesic Aquic Hapludoll) and Canisteo (fine-loamy, mixed, superactive, calcareous, mesic Typic Endoaquoll) soils and reduced to 4 and 16 mg kg 21 d 21 NO 3 2 -N when Stay-N 2000 was added. The extension of t9 due to the addition of Stay-N 2000 was as high as 7 d in the Nicollet soil at 10 uC and 21 kPa and as little as 2 d in the Canisteo soil at 20 uC and 210 kPa.
