Fertilizing Miscanthus / Elephant Grass


Miscanthus Field

Since, starting in mid-September, the large part of the nutrients consumed and the assimilants formed re-locates to rhizomes, only minor amounts of any fertilizers will settle out. The leaves fallen stay in the field as a mulch layer. Due to no seed/fruit formation, the need for nutrients is significantly lower than in comparable arable crops.

Nitrogen-based fertilizing is recommended at the earliest in the 2nd year, bt the crop can also be realized without any fertilizing at all. In good locations, this is only reasonable starting from the 8th of 9th year. In general, the fertilizer should be distributed immediately upon harvesting (April/May). You can also drive across the field with a fertilizer spreader.

Fertilizer Types:

  • Potassium: Removing ashes from the surface is possible and recommended after the first several years
  • Manure: Generally, manure distribtion would be advised against; however, if you still would like to, then in only small amounts.
  • Nitrogen-(N)-Based Fertilizers: This fertilizer provides its effect upon harvest in even insignificant amounts. Only 60 kg of N/ha can exhaust the earning potential (mineral fertilizer), the maximum shall not exceed 100 kg N/ha/a.
