An Agroscope study shows that pre-flowering removal of the main leaves instead of the lateral shoots appears to be a viable practice with a moderate effect on both yield potential and must composition.
Foliar fertilisation around veraison improves grape nitrogen levels without affecting vigour. A trial shows that the fertilisers ‘Safe N 300’ and ‘Folur’ effectively increase assimilable nitrogen in the grape must; however, their degree of effectiveness depends on climatic conditions.
Summer droughts reduce grassland yields and forage quality. More drought-resistant than herbaceous species, certain trees can provide supplementary forage of good nutritional value in summer. Increasingly intense summer droughts have led to a sharp decline in the yields and nutritional value of grassland forages. Producing sufficient supplies of quality forage has therefore become a genuine…
