L'Observatori de la Sequera a la Terra Alta (OSTA) fa un seguiment de l'estat hídric de la vinya a la Terra Alta. Cada setmana publica un butlletí amb informació sobre la precipitació i la humitat del sòl a finques de secà. Per les finques de regadiu també realitza recomanacions de reg. Els butlletins es publiquen cada dilluns pel matí.
L'Observatori de la Sequera a la Terra Alta és una prova pilot del projecte LIFE CLINOMICS, realitzada per l'Observatori de l'Ebre amb el suport de l'Escola Agrària de Gandesa, per encàrrec de Consorci de Polítiques Ambientals de les Terres de l'Ebre (COPATE).
Si voleu rebre els butlletins al vostre telèfon mòbil, us podeu subscriure al canal de Telegram de l'OSTA.

Variació de la brúixola a Roquetes
La brúixola marca el nord magnètic, no el nord geogràfic. El nord magnètic varia amb el temps. Durant els darrers segles, a Roquetes, les brúixoles estaven desviades cap a l'oest. Però això ha canviat i ara es desvien cap a l'est. Més informació.
