“…A decrease in NH 4+-N is likely to be due to utilization of this ion by soil microorganisms. Immobilisation of NH 4 +-N by soil microbes has been reported by a number of workers 12,15,16,25. Also, nitrification brings about a decrease in the concentration of NH4+-N. A decrease in NO3--N is brought about as a result of immobilisation and denitrification by the general soil microflora and denitrifiers respectively 1.…”

KEY WORDSAerobic Ammonium Anaerobic C/Nratio Green manures zation Nitrification inhibition Nitrification stimulation Incubation N minerali- SUMMARYThe pattern of release of ammonium and nitrate nitrogen during decomposition of glyricidia, sunflower, centrosema, calapagonium and crotolaria under aerobic and anaerobic conditions, in an alluvial soil over a period of 7 weeks was studied. Under aerobic conditions, the NH 4 § production reached the maximum after the 4th week. Nitrate-N and total available-N increased in all cases throughout the incubation period except in sunflower. This showed a nitrification inhibitory effect and had a relatively high C/N ratio (11.0) and low total N content (2.8~). In general the increase in NH4+-N and NO 3 --N was more rapid in the early stages of incubation.Under anaerobic conditions, the production of these nutrients was considerably low. Soil organic matter mineralized faster than the added organic material which started to decompose slowly after sometime. Nitrate-N tend to decrease during incubation attributable to denitrification.

“…For a material such as straw, deficient in nitrogen content (Russell, 1954), the addition of nitrogen greatly enhances microbial degradation. Pinck et al (1946) have shown that 14-25 units (1 unit=M2 lb=0-51 kg) of nitrogen (N) are immobilized by 1 ton (1-016 tonne) of straw (an approximation of the quantity of straw produced per acre), and it is thought that nitrogen availability may be a factor limiting straw decomposition in many wet autumns and winters as a result of pronounced leaching. Experiments were devised to investigate the effect of stubble treatment and of rate and form of nitrogen applied to the stubble in the autumn on the incidence of take-all and eyespot in the succeeding cereal crop.…”

SUMMARY Commercial‐scale field trials on farms in North Hampshire over four seasons (1963 to 1968) showed that nitrogen applied to wheat or barley stubble after harvest in the autumn failed to reduce the incidence of take‐all and eyespot in the succeeding wheat or barley crop, or produced only minor reductions in the spring which were not maintained up to the stage of crop maturity. There were no consistent significant differences in levels of disease between rate or form of nitrogen applied as urea/ammonium nitrate spray at 0, 12, 24 or 48 units/acre (1 unit/ac × 1·25 kg/ha), ammoniacal gas liquor spray at 48 units/acre and anhydrous ammonia injected at 40 units/acre. Burning‐off stubbles with high‐output flame cultivators did not significantly reduce the incidence of either disease.

The effects of solution and granular N fertilizers and straw on the nitrate (NO3) content of soil and cotton petioles were studied in the laboratory and field. In the laboratory, applications of solution N with straw to soils generally resulted in more rapid mineralization of N when compared with granular applications. In the field, applications of N increased soil and petiole NO3 but tended to decrease cotton yields. Granular rather than solution N applied to straw and bare soil generally produced the highest NO3 content of the soil but there was no difference in petiole NO3. Straw alone decreased yields but did not affect soil and petiole NO3. Straw plus N tended to decrease soil and petiole NO3 when compared with N applications alone. N in the solid form at a rate of 125 pounds per acre produced yields statistically equal to the check treatment.
