To leave a field fallow will allow one year in fertility improvement due to natural weathering and no crop removal. The year with no tillage can improve the amount of soil organic matter while a non crop year can reduce disease and insect pest levels. These factors together can increase crop yield in future years.
This is why fallow land is cultivated only once or twice in 2-3 years.
