> AgWeb reports that closure of the Strait of Hormuz has driven up US farm input costs, including on-farm diesel which is approaching record March 2022 levels and is more than $1 above last year. Urea prices are reported up 39%, with a quarter of global fertilizer supplies passing through the strait.
