“…, 1991). The N‐use efficiency of that applied in the slurry treatments in this study was higher than typically obtained in surface applications to grassland (Long and Gracey, 1990). The relatively mild winters and the growth rates of Italian ryegrass in winter could possibly have promoted the high N‐use efficiency found in treatments where slurry was applied at three different times of the year (treatments T3 and T4) when compared with treatment T2 with total application of slurry in spring, contrasting with results obtained by Sieling et al.…”

Efficient use of cattle-slurry to avoid nitrogen (N) leaching and other losses is important in designing intensive dairy systems to minimize pollution of air and water. The response in dry-matter (DM) yield of herbage and nitrate-leaching potential to different rates and timing of application of N as cattle slurry and ⁄ or mineral fertilizer in a double-cropping system producing maize (Zea mays L.) silage and Italian ryegrass (Lolium multiflorum Lam.) was investigated in north-west Portugal. Nine treatments with different rates and combinations of cattle slurry, and with or without mineral-N fertilizer, applied at sowing and as a top-dressing to both crops, were tested and measurements were made of DM yield of herbage, N concentration of herbage, uptake of N by herbage and amounts of residual soil nitrate-N to a depth of 1 m, in a 3-year experiment. Regression analysis showed that the application of 150 and 100 kg of available N ha )1 to maize and Italian ryegrass, respectively, resulted in 0AE95 of maximum DM yields of herbage and 0AE90 of maximum N uptake by herbage. Residual amounts of nitrate-N in soil after maize ranged from 48 to 278 kg N ha )1 with an exponential increase in response to the amount of N applied; there were higher values of nitrate-leaching potential when mineral-N fertilizer was applied. The results suggest that it is possible in highly productive maize ⁄ Italian ryegrass systems to obtain high DM yields of herbage for maize silage and Italian ryegrass herbage with minimal leaching losses by using slurry exclusively at annual rates of up to 250 kg available N ha )1 (equivalent to 480 kg total N ha )1 ) in three applications.

“…Larger amounts of N, but also other nutrients, in T2 caused a significantly higher DM yield in 1999 and 2000 (72 and 111%, respectively) compared to T1 (Table 1), primarily due to the positive action of N on grass yield in the first cuts. The trend reported by Long and Gracey (1990) of a slurry-fertilizer combination being more effective than inorganic fertilizer at the 1 st harvest, followed by little difference in the response to N source at the 2 nd harvest, was confirmed in this research as well (data not shown). According to the authors, the reasons for such trends might be higher ammonia losses in warmer and drier conditions at the time of summer applications of slurry, for the first regrowth, compared to equivalent spring-time applications.…”

“…These results have the same trend as the studies by Lim et al (2003), Choi and Yook (2000), and Lim et al (2006). On the effect of application of LSM compared to CF, Jin et al (1996) claimed that the animal manure application increased maize production by the chemical improvement of soil, Pain et al (1986) and Long and Gracey (1990) reported that the application of low concentration LSM in high temperature drought period increased the production of forage crops, because it reduced moisture stress owing to the supply of a large amount of water in addition to the fertilizer effect.…”

This study was performed out to investigate the influence of the mixed application of chemical fertilizer (CF) and liquid swine manure (LSM) on the growth characteristics, dry matter yield, amino acids, minerals, and free sugars in cultivating silage corn on paddy soils. The field experiment was designed in a randomized block design of 3 repetitions with CF 100% treatment (C), CF 70% + LSM 30% treatment (T1), CF 50% + LSM 50% treatment (T2), CF 30% + LSM 70% treatment (T3), and LSM 100% treatment (T4). At this time, the application of LSM was based solely on the nitrogen. Ear length, ear circle, stem diameter, and stem hardness of the silage corn did not show significant differences between treatments. Fresh yield, dry matter yield and TDN yield were highest in T3, whereas the lowest in C treatment (p<0.05). Crude protein, crude fat, and crude ash content were significantly higher in T1, C, and T4 treatment, respectively (p<0.05). However, NDF, ADF and crude fiber content did not show significant difference between treatments. The total mineral content decreased significantly (p<0.05) as the LSM application rate increased. Total composition amino acid content was higher in the order of T1 > T2 > C > T4 > T3 treatment (p<0.05). Free sugar content was higher in the order of T1 > T3 > T4 > T2 > C treatment (p<0.05). Based on the above results, suggests that the mixed application of chemical fertilizer 30 50% and LSM 50~70% (T2 and T3) is the most effective, considering the yield performance and the content of sugar degree and free sugar affecting silage.

Effect of fertilizer nitrogen source and cattle slurry on herbage production and nitrogen utilization

Abstract: A field plot experiment was carried out on an established grassland sward from 1983 -88 inclusive to examine the effects of time of application, chemical form of nitrogen (N) and cattle slurry dry matter (DM) content on yield and efficiency of N use.
