Since 2016, I've been helping out the young guys from TEND in the development of a crop planning software for fresh-market vegetable farms. The product is really awesome, but still under development.  We've started using it on the farm and can honestly say that it's a game changer,  incomparable to all other crop planning software out there. I recommend signing up to their newsletter to get updates about their launch in 2018. TEND management software
