Dynamic lifter is processed organically to both fertilise and encourage microbial activity in most soil types. This is why it is so effective at its task. However, it's by its nature not so effective in providing essential trace elements. This is where a varied regime of compost (the best fertiliser of all), liquid manure feeds (you know, the old the old poo in the potato bag suspended in the 44 gallon drum, and seaweed soil conditioners help to achieve overall health and vitality to plants, microbes and microflora. Just as we require a varied diet in moderation, so too does the garden. Personally I swear by it. I would usually lightly top dress monthly from early spring to high summer, or about 4 times during the "growing season".
