Mesures herbe\u00a0: comment \u00e7a marche\u00a0?<\/strong><\/span><\/p>\n

Les donn\u00e9es chiffr\u00e9es figurant sur la carte de la m\u00e9t\u00e9o de l\u2019herbe sont exprim\u00e9es en kg de MS\/ha\/jour. Ces mesures sont r\u00e9alis\u00e9es chaque d\u00e9but de semaine sur des exploitations de plaine, plateau et montagne (> 800m) selon leur type de sol (superficiel ou profond).<\/p>\n

Ces croissances traduisent des \u00e9carts de mesure de hauteurs d\u2019herbe d\u2019une semaine \u00e0 l\u2019autre fournies par l\u2019herbom\u00e8tre. En multipliant ces hauteurs par une densit\u00e9 de l\u2019herbe au p\u00e2turage (en moyenne 250 kg de MS\/cm avec des \u00e9carts de 190 \u00e0 270 kg selon la saison et le type de prairie), on d\u00e9termine la croissance journali\u00e8re.<\/p>\n

Exemple\u00a0: mesure semaine en cours = 9.5 cm \u2013 mesure semaine pr\u00e9c\u00e9dente (7.5 cm) = 2 cm x 250 kg MS\/cm = 500 kg MS\/7 jours = 71 kg de croissance\/ha\/jour.<\/p>\n

Un cumul des mesures herbes sur les parcelles p\u00e2tur\u00e9es permet de faire une moyenne et au-del\u00e0 de d\u00e9terminer un stock d\u2019herbe disponible \u00e0 un moment donn\u00e9 pour d\u00e9terminer le nombre de jours d\u2019avance au p\u00e2turage afin de prendre les bonnes d\u00e9cisions (ex\u00a0: d\u00e9brayage de parcelle en fauche si n\u00e9cessaire)<\/p>\n

Les croissances moyennes potentielles mesur\u00e9es depuis 2008 servent aussi \u00e0 d\u00e9finir des surfaces \u00e0 allouer au p\u00e2turage selon la p\u00e9riode (cf. tableau)<\/p>\n
