Strawberries are heavy feeders of minerals, to replenish the mineral loss I have taken to amending with a side dressing of sea minerals from seaagri, when I side dress I use a mix of compost, composted manure and now I add a cup of seaagri minerals to the mix. This has not only made healthier plants but it keeps them producing longer and I don't anticipate any slowdown at year three since I am replenishing the soils with the minerals. I also have not noticed any of the previous leaf diseases or pests. I also have a test bed growing in straw bales which had a few problems prior to my first application of the seaagri minerals.
I don't think you would have to move the berry beds if you were to side dress on a regular basis to replenish the soil losses caused by the berry plants.
I like to use the leaf color as one of my indicators of soil health.
The grazing of the berry plants is a good idea, it causes the roots to replenish, much like digging them up and transplanting them. We get a huge number of runner babies in the straw bale bed, these will most likely bear their second year. I anticipate having to move this particular bed of berry plants simply because the straw bales deteriorate over a three year period. When this happens I will move the plants to a raised bed filled with one of our mixes and this experiment will start a new set of record keeping.
