How has science helped us in the field of agriculture?

Agriculture is itself a science. The study of soil types allows us to know which one is suitable for which crop and how much watering should be done. Engineering allows us to build better devices that make farming easier, like irrigation systems, vehicles, etc. The study of plant growth allows us to plan growing periods, and also get better yields. Genetic manipulation allows us to get better varieties. These are few among the different ways in which science has allowed sustainable agriculture.
