just woundering why the purity dropped so much.
i bought cereal seeds at 56% pure planted them on an existing field. i harvested this crop all still had about 56 purity. i made seeds 56 pure then planted all those seeds on new freshly tilled fields when i harvested these crops all purity fell bellow 3 percent. i didn't mix the seeds and noted when i planted that they were at 56 %.
can anyone explain why that happened
