Long-term effects of pig slurry combined with mineral nitrogen on maize in a Mediterranean irrigated environment
Intensive pig farming generates large amounts of manure which is applied to agricultural fields as slurry. It is therefore important to know the nitrogen (N) fertilizer values and long-term environmental effects of different pig slurry application rates. We investigated the performance of sprinkler-...

| 520 | |a Intensive pig farming generates large amounts of manure which is applied to agricultural fields as slurry. It is therefore important to know the nitrogen (N) fertilizer values and long-term environmental effects of different pig slurry application rates. We investigated the performance of sprinkler-irrigated maize crops in a Mediterranean environment with different fertilizer treatments as part of a 12-year experiment (2002–2007, 2010–2015). We compared pig slurry applied using the surface splash plate method at rates of 0, 30 and 50m3 ha−1 yr−1 combined with mineral N fertilizer application rates of 0, 100 and 200kgNha−1 yr−1 as a side-dressing. The fertilizer treatments affected maize grain and biomass yields, N uptake, chlorophyll levels, soil N levels, N use efficiency (NUE) and basal stalk nitrate levels. Satisfactory average grain yields (∼13.5Mgha−1) were achieved at application rates of ∼200–300kgNha−1 with average residual soil N levels below 180kgNha−1 (0–90cm depth) and a NUE greater than 50%. However, the maximum average grain yields (∼14.5Mgha−1) required treatments providing more than 400kgNha−1 yr−1 but resulted in residual soil N levels greater than 300kgNha−1 and the NUE fell below 50%. The 12-year average relative N fertilizer value of pig slurry applied at 30 and 50m3 ha−1 yr−1 was 51% of the mineral N value applied at side-dress, suggesting that more efficient application methods for pig slurry are required. The end of season basal stalk nitrate test was useful for the quantification of excess nitrogen, and 2.5g NO3 − kg−1 was considered the maximum optimal concentration for our cropping conditions and grain yields. | ||

Long-term effects of pig slurry combined with mineral nitrogen on maize in a Mediterranean irrigated environment |
| abstract |
Intensive pig farming generates large amounts of manure which is applied to agricultural fields as slurry. It is therefore important to know the nitrogen (N) fertilizer values and long-term environmental effects of different pig slurry application rates. We investigated the performance of sprinkler-irrigated maize crops in a Mediterranean environment with different fertilizer treatments as part of a 12-year experiment (2002–2007, 2010–2015). We compared pig slurry applied using the surface splash plate method at rates of 0, 30 and 50m3 ha−1 yr−1 combined with mineral N fertilizer application rates of 0, 100 and 200kgNha−1 yr−1 as a side-dressing. The fertilizer treatments affected maize grain and biomass yields, N uptake, chlorophyll levels, soil N levels, N use efficiency (NUE) and basal stalk nitrate levels. Satisfactory average grain yields (∼13.5Mgha−1) were achieved at application rates of ∼200–300kgNha−1 with average residual soil N levels below 180kgNha−1 (0–90cm depth) and a NUE greater than 50%. However, the maximum average grain yields (∼14.5Mgha−1) required treatments providing more than 400kgNha−1 yr−1 but resulted in residual soil N levels greater than 300kgNha−1 and the NUE fell below 50%. The 12-year average relative N fertilizer value of pig slurry applied at 30 and 50m3 ha−1 yr−1 was 51% of the mineral N value applied at side-dress, suggesting that more efficient application methods for pig slurry are required. The end of season basal stalk nitrate test was useful for the quantification of excess nitrogen, and 2.5g NO3 − kg−1 was considered the maximum optimal concentration for our cropping conditions and grain yields. |

It is therefore important to know the nitrogen (N) fertilizer values and long-term environmental effects of different pig slurry application rates. We investigated the performance of sprinkler-irrigated maize crops in a Mediterranean environment with different fertilizer treatments as part of a 12-year experiment (2002–2007, 2010–2015). We compared pig slurry applied using the surface splash plate method at rates of 0, 30 and 50m3 ha−1 yr−1 combined with mineral N fertilizer application rates of 0, 100 and 200kgNha−1 yr−1 as a side-dressing. The fertilizer treatments affected maize grain and biomass yields, N uptake, chlorophyll levels, soil N levels, N use efficiency (NUE) and basal stalk nitrate levels. Satisfactory average grain yields (∼13.5Mgha−1) were achieved at application rates of ∼200–300kgNha−1 with average residual soil N levels below 180kgNha−1 (0–90cm depth) and a NUE greater than 50%. However, the maximum average grain yields (∼14.5Mgha−1) required treatments providing more than 400kgNha−1 yr−1 but resulted in residual soil N levels greater than 300kgNha−1 and the NUE fell below 50%. The 12-year average relative N fertilizer value of pig slurry applied at 30 and 50m3 ha−1 yr−1 was 51% of the mineral N value applied at side-dress, suggesting that more efficient application methods for pig slurry are required. The end of season basal stalk nitrate test was useful for the quantification of excess nitrogen, and 2.5g NO3 − kg−1 was considered the maximum optimal concentration for our cropping conditions and grain yields.</subfield></datafield><datafield tag="520" ind1=" " ind2=" "><subfield code="a">Intensive pig farming generates large amounts of manure which is applied to agricultural fields as slurry.
