Kernrechtsfrage
Whether the cantonal court acted arbitrarily in assessing the husband's earning capacity at 70% and imputing CHF 900 monthly net income from outside farming work.
Extrahierter Entscheid
The assessment was not arbitrary; the medical report and the husband's age made the 70% work capacity and the imputed income plausible.
Extrahierte Begründung
The court accepted a 70% overall work capacity based on the medical report, and the wife's alternative earning scenario did not make the cantonal court's estimate untenable.
