… there was a blight. and potatoes were the only crop they could grow because the British both strategically broke up the land held by Irish tenants to be tiny, and also forced the export of most other things. there was enough food in Ireland during the famine, there was not enough of the food that the British allowed the Irish to eat.
Yet they also contributed to the situation by not fertilizing their fields with anything other than potato peels. And by not planting in different locations or different field sections. The Irish maintained livestock and didn’t engage in rotational grazing, despite the prevalent knowledge of how helpful it was.
with what exactly? when you’re effectively a feudal peasant living on a plot too small to support you with anything besides potatoes. the irish didn’t really have livestock, the English and Scottish planters did. Hence why Ireland exported tons of grain and meat, hence why many starving people were sent to Australia for stealing that food to keep their families alive.
With their fucking livestock’s shit—just like every other agricultural community in the world was doing at the time. Graze a field, plant a field. Rotate. It was common knowledge. The Irish absolutely have livestock. My grandparents still live there. You can see it in every fucking paper and journal time period.
