Soil, in and on the ground, gets re-used every year, for millennia. Sensible gardeners and farmers rotate crops and improve the soil to maintain health and productivity of both soil organisms and crops.
Planting media - aka compost in pots and troughs and baskets - should be used once and then discarded as a soil conditioner or addition to a compost heap.
Your questions are becoming persistently repetitive and rather dumb now and you are consistently disregarding advice, freely and generously given by many. Either you are a deliberate pest or you are all talk and no trousers and need to get your hands dirty and try things. I, for one, will be using the Ignore button from now on.
