Agricultural productivity is like measuring how much food, crops, and other things grown on a farm. It is like keeping track of how many things the farmer can make off their land. Farmers measure their agricultural productivity by keeping track of how many things they can grow and make off their land in a certain time period, like a year. So, if they had the same seeds, sunlight, and water all year, did the same type of work, and still were able to get more things than the year before then that means their agricultural productivity increased, which is good for them!
