The composting process results in immobilization of inorganic N. When high-Ndemanding crops are grown in compost- amended soils, additional N fertilizer is often applied. The combination of elevated nitrate levels from N fertilizer and high C inputs

Application of raw animal manure to agricultural land has resulted in environmental and health problems. Alternatives, such as composting, are now being developed to alleviate this situation. However, very little information is available regarding th

Various long-term crop management strategies are known to have differing effects on soil organic C. This laboratory study explored the effect of long-term (35 yr) fertilization and crop rotation on soil organic C and denitrification capacity at diffe

Nitric oxide reacts with C 2 H 2 at ambient temperature under aerobic conditions with relatively large quantities of 02 present. We used a gas-flow system at 20°C to determine the extent, if any, of reaction of NO with C 2 H 2 under nearly anaerobic

Numerous papers on nitric oxide have been published covering various aspects ranging from its solution and gas-phase chemistry, biochemical and physiological functions and atmospheric processes. This review emphasizes recent developments in the liter

Acetylene inhibition of N2O reduction to N2 is traditionally used to estimate denitrification. Although NO is also produced in the denitrification process, the effect of C2H2 on NO production in denitrification has not previously been examined, mainl

Although the use of cover crops and intercrops has been increasing, little information exists on effects these plant residues may have on soil microbial processes. Our objectives were to determine effects of several crop residues representing a range

To determine the inhibitory effect of O2 on denitrification in pure cultures of Pseudomonas fluorescens, measurements of net NO and N2O production rates, fNO and fN2O, under anaerobic conditions were compared to rates under partially aerobic conditio

Some aspects of the physiological role of NO may be mediated by stable NO-carriers such as S-nitrosoglutathione and related S-nitrosothiols. In this report we show that irradiation of S-nitrosoglutathione at either absorption band (lambda max = 340 n
