can i plant my tomatoes in the sme soil as last year in my greenhouse if i add fresh compost.  what about pests in soil?

The simple answer is yes provided the soil gets a good refresh. I've been growing toms in the same patch for eons with a good refresh of the soil each year. Toms are less likely to be bothered by pests in the soil than by, for example, fungal spores that might have fallen onto the soil from last year's leaves, or some of the viruses that can live on in soil. Fungal spores that remain on the soil surface from last year can splash back up onto the leaves when watering this year, but spores that are effectively buried when the soil is refreshed are no longer a problem. If last year's plants were virus-free, you should be fine this year. If, though, any of the viruses were to turn up, you'd need to rethink the location.

spot on the definitive answer i was looking happy growing
