N2o Fluxes

Cattle slurry injection (INJ) has shown to be an efficient measure to reduce ammonia (NH3) losses from soils but it might also significantly increase nitrous oxide (N2O) emissions, which can dominate the total greenhouse gas (GHG) release in silage maize production (Zea mays L.). Nitrification inhibitors (NIs) are known for their potential to mitigate N2O. Therefore, we tested the effect of NIs added to cattle slurry before INJ on N2O fluxes from a Haplic Luvisol under silage maize in southwest Germany. We determined N2O fluxes at least weekly, with the closed chamber method over two full years. NIs differ in their chemical and physical behavior and we therefore tested a range of commercially available NIs: 3,4-dimethylpyrazole phosphate, 3,4-dimethylpyrazol succinic acid, a mixture of both, nitrapyrin, dicyandiamide, and 1,2,4 triazol and 3-methylpyrazol. Although not significant, INJ treatments with NI showed lower mean annual N2O emissions than the INJ treatment without NI in the 1st year. The emission reduction by NI of 46% in the 2nd year was statistically significant. In both years, we did not find any difference in N2O release, crop yield, or nitrogen removal between the different NI treatments. In the 1st year, which was extraordinary dry and warm, emission factors (EFs) for all INJ treatments were 4 to 8-fold higher than default EF from the IPCC. Even in the 2nd year, only three NI treatments reached EFs within the range provided by the IPCC. Direct N2O accounted for between 81 and 91% of the total GHG emission. Area- and yield-related GHG emission of the broadcast application with subsequent incorporation was in both years in the statistical class with lowest emission. In contrast, INJ with NIs showed similar GHG emissions in only one year, and consequently, incorporation was found to be the optimum management practice for livestock farmers in our study region.

Injection Treatment

In field trials in 1993-94 on sandy soils at 2 sites in the Netherlands, cattle slurry was applied by injection into slots 25 cm apart (standard injection) or 75 cm apart (banded injection). Subsequently, maize cv. Melody or Mandigo was sown at a row spacing of 75 cm parallel to the slots, either at random lateral positions in the standard injection treatment or 10 cm from the injection slots of the banded injection treatment. All treatments, including a control without slurry, were combined with 0 or 20-31 kg/ha of subsurface banded P starter fertilizer. Dry matter yields of silage maize were on average reduced by 8% when standard injection of slurry was not supplemented with P. However, the yield reduction was only 2% when slurry was banded.

Negative Impacts

Relatively little is known about potassium leaching losses following harvest of silage maize. While direct negative impacts on the environment are unlikely, losses of K with leaching need to be known for accurate balancing, especially on coarse textured soils, where K can be a critical element. In a four-year field experiment the effects of fertilizer forms (inorganic, cattle slurry and pig slurry) and four levels of N input (0, 80, 160, 240 kg N/ha) with corresponding amounts of K on the nutrient balances and leaching of K from silage maize grown on a sandy soil were investigated using suction cups. After four years, surplus of K from cattle slurry led to higher lactate-soluble K in the topsoil. Potassium leaching differed between years with different amounts of rainfall during winter. Annual leaching losses of K increased with N and K input and amounted to 38 kg K/ha, while fertilizer form had no significant effect. Losses of K increased with increasing N leaching (R<sup>2</sup> = 0.69). We conclude that in maize production on coarse textured soils and under conditions of high N leaching (86&ndash;152 kg N/ha), K leaching can be large (6&ndash;84 kg K/ha) and constitutes a relevant part of K balances (&ndash;84 to +127 kg K/ha). &nbsp; &nbsp;

Cropping Sequence

In field trials at Wageningen in 1979-86, forage maize cv. Dorina was given 100 t cattle slurry/ha and grown in a long (sugarbeet/1 or 2 years barley/potato/maize) or short (potato/maize) rotation, or continuously cropped. Nematicides were applied to each crop in all rotations. The effects of soil treatment with pencycuron, benomyl, metalaxyl or gamma -irradiation were studied in 1986 in pot experiments using soil from the field trial plots for each cropping sequence. Roots were given a healthiness ranking in each year. Yields were 10-20% lower with continuous cropping and a prolonged short rotation. Neither annual applications of slurry nor nematicides reduced the adverse effects of continuous cropping. Continuous cropping stimulated root rot. There was a close negative relation between cropping frequency, incidence of root rot and maize yield. Root rot seemed to be caused mainly by Pythium spp., and seemed to occur more seriously in years when the first half of the growing season was wetter than normal.
