Application instructions

ProtaPlus is a product for short-term forage production (6-12 months). It can be used as an intercrop between arable crops like corn, cereals or cotton. ProtaPlus can be harvested 2-3 times and used as silage, hay or as fresh feed, which is directly fed to animals. Grazing is also possible, as long as rotational- or strip-grazing is applied.


Sowing recommendations

Annual clovers need a warm period to establish, so don’t sow too early or late in the season: soil temperature should be > 12 °C.

Annual clovers require a minimal pH of 5.5 – 6.0. For lower soil-pH liming is recommended.

Sowing in humid soil, very fine seedbed, comparable to sugar beets or lucerne.

Sowing period

August – October (Mediterranean climates)

April – August (Mild/oceanic climates)

Seed rate 30 kg/ha
Sowing depth 0.5 - 1.0 cm. After sowing use a roller to compress the soil


ProtaPlus can be harvested 2-3 times per season (4-6 weeks interval).

Cut before the clover starts to bloom.

Don’t cut too low: cutting height no lower than 7-8 cm.

Tedding and raking should be done smoothly, to prevent losses from cloverleaves.

Make sure the sward isn’t longer than 15 cm before winter.




As a starter fertilization special attention should be paid to P, K and S.

N-fertilization isn’t necessary. Possibly apply max. 25 kg/ha N before the 1st cut.

Animal manure/slurry to be applied before sowing.

Artificial fertilizer to be applied from two weeks after sowing onwards (spring/summer sowing), or shortly after winter (autumn sowing).
