SPRAYING HORN MANURE / Jan Erbach of the Pian dell’Orino winery in Montalcino sprays Horn manure 500 by hand using a back sprayer. ‘I spray it rhythmically and in a figure of eight and it is important that the person who is spraying gets into this rhythm. On a practical level spraing this way alsa ensures the Horn manure spray gets right under the vines and around the vine trunks, rather than just being sprayed only on the middle of the row,’ he says.
