Farmers urged not to delay spreading remainder of slurry this autumn

Teagasc is urging all farmers not to delay spreading the remainder of their slurry this autumn.

The nitrogen in slurry spread in September can have a higher impact on grass growth. As grass growth reduces from September onwards, the capacity to take up nitrogen (N) reduces steadily. 

Any N not used by grass is susceptible to leaching when autumn and winter rains come – particularly in free-draining soils.

Good practice this autumn

  • Look at your grass covers and identify if your farm has a sufficient supply of grass;
  • Identify paddocks that are likely to respond to additional Nitrogen based on soil conditions, grass covers and soil fertility;
  • At this point, no more than 20Kg N per hectare is justified. In situations where there are significant grass covers and moderate to low stocking rate, it is likely that no chemical fertiliser is required.
  • Last date for spreading chemical N&P is midnight on September 14th;
  • Apply remaining slurry as soon as possible using low emissions slurry equipment where available.

This will lead to:

o   Good uptake of the Nitrogen in slurry by the plant and avoiding losses to water from late applications;

o   Avoiding the risk of not being able to empty tanks, if weather conditions worsen;

o   Save money by getting effective use of slurry nutrients;

o   Empty tanks to protect your storage capacity for the spring.

Reducing nitrate loss to water is an essential part of protecting our environment and farm income, the state agency added.
