Carbon sequestration in soils is often mentioned in the discussions about climate changes. In this paper the opportunities for carbon sequestration in Dutch agriculture are discussed at farm and national level. Farm internal carbon sources are already completely used in livestock farming. The effect under arable conditions is limited in time and very limited compared to national CO2 emission. External sources are scarce. Energy production out of crop residues and manure via biogas installations is possible but the overall impact is again very limited. The effect of this biogas pathway on soil organic matter quantity and quality is not yet known. Organic arable farmers do already have a higher soil organic matter content than conventional farmers, partly... |

In a two-year field experiment in the Netherlands the relation between three soil fertility strategies, additional nitrogen levels and Fusarium Head Blight in wheat are explored. There was a substantial year-effect, as could be expected. The soil fertility strategies showed differences, but were party coinciding with location. Although not consistent over the years and strategies, a significant relation was found between additional nitrogen applications around anthesis and FHB, expressed as presence of mycotoxines (DON) and Total Root Rot from the Blotter test. Higher nitrogen levels from fertilizer applications at anthesis give a higher chance on FHB, with other so far unknown factors playing a role. |

Fusarium spp. present on spring wheat seeds can infect seedlings and cause reduced plant densities and higher wheat infestations. In the current project, variation between commercially available spring wheat cultivars in their tolerance to Fusarium seedling blight was investigated in a pot and a field trail. Additionally, initial growth rates of cultivars were measured to investigate possible relations with tolerance. Preliminary analysis shows presence of tolerance differences between the spring wheat cultivars in the pot and field experiment. This difference was relatively robust (experiment x cultivar interaction was not significant). Preliminary analysis also showed a relation between tolerance and initial growth rates of cultivars in the field... |
