100 compost is a products (not a waste) that can be spread on land with
minimal complications from red tape. Unlike compost spread as a waste, there is
no deployment
needed from the Environment Agency and no
Spreading Permit either.
Whilst waiting to apply for the paper work from the EA could put you in a better
position financially it is a very time consuming process. Compost not only supplies
nutrients to soils, it also has the advantage of improving the soils
structure, loosening clay soils, and improving water retention in
granular soils. The nutrients are also slowly released unlike highly
soluble Artificial Fertiliser, which can be washed largely leached
(washed) out in just one season.
Below we will attempt to examine the cost of
compost when compared with artificial fertilizers.

Whilst it is obvious that compost has lower quantities of nitrogen weight for weight when compared with artificial fertilisers, it should be bourn in the mind that application rates for compost (tones per hectare) will be higher than their artificial equivalent. Costs for compost are around 20% - 40% of conventional / artificial fertilisers. Compost also improves soil structure and has many important micro nutrients such as boron and manganese.
