Any rates that we recommend should also take into account the nutrient levels in your own soil.  In studies it has been found that many private gardeners are using up to 5 times the amount of fertiliser than is necessary.  Our recommendation is that you either invest in a soil testing kit or send a sample to a soil analyst service for advice before using fertilisers.  We also advise caution with regard to waterways as overuse can cause run off and contamination.  Applying fertilisers little and often and then retesting your soil is good practice.

Fertiliser manufacturers may legitimately include some inert material like clay or sand into their products in order to act as a carrier to ensure that the correct levels of nutrient are present in that particular compound.
