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…

The stem nematode Ditylenchus dipsaci causes damage to field crops. The pest attacks many different host plants. We examined these plants’ susceptibility to D. dispaci and, based on our findings, recommend crop rotation.
