All TOPSOIL products are developed from the soil that adheres to the sugar beet delivered to British Sugar’s factories and as such comes from the best agricultural soils in the country. After separation, the soil undergoes a gravity settlement stage prior to a lengthy conditioning process and careful storage ready for delivery to you.
Good topsoil is a mixture of mineral particles, water, nutrients, organic matter, air and living organisms.
Exact proportions of each are not particularly critical but to constitute a “good” soil it should contain all these elements. Ideally it should conform to the newly revised 'British Standard for topsoil' BS3882:2007.
