Fallows are non-productive agricultural periods that take place between 15th January and 15th July. During this time, arable land has no crop production or grazing taking place, which allows naturally occurring species to refurbish the soil for future crop production. Fallow seed mixtures that comply to AB15 provide a solution for environmental land management. This helps to provide food for farmland wildlife and pollen for insects such as bees, butterflies, and hoverflies. Oliver Seeds offer a variety of fallow mixtures.
