How did the black death affect farming and crops

It decimated the population, mainly in metropolitan areas, but also in the country. Death was relatively quick. dead people can't plow, harvest, or sell crops, so I would think that fields lay fallow, crops rotten in some fields, and farms in many instances just fell into ruins.
hope this helped :)

Tenochtitlán was the capital of the aztec empire. it was a busy and bustling city where“there are daily more than 60,000 souls, buying and selling, and where are found all the kinds of merchandise produced in these countries.” when cortes arrived in 1519, theenormity of the trading market and the smoothness of it’s running both surprised and  impressed him.
