Soil Improver is a totally organic, sustainable, and natural plant waste material from the biogas industry. Made in Somerset from composted grass, maize, and rye, it is 100% natural, and contains a rich source of low-level nutrients to slowly feed your soil and plants. And most importantly it is Peat-Free, and a low energy option compared to coir and other peat alternatives. Peat is not a great soil improver and should not be used for this purpose. Our natural Soil Improver contains low levels of natural slow-release feed, bioactive microbes to invigorate your soils and adds lovely fibre structure to improve clay and poor soils to make them easier for plants to root in. Not only is our Soil Improver eco-friendly – even our bags are sustainably sourced. Made in Southampton – maintaining our ecological footprint by saving on airmiles – from 30% recyled plastic, the bags are 100% recyclable in all supermarket bag collection points. You can also rest assured that our products are Soil Association Approved for organic growing and contain a natural source of N:P:K. All in all, this is a product that has minimum impact to Mother Nature, and maximum impact on your homegrown produce. Dig in a 1-2′ (2.5-5cm) deep layer, depending on how poor soil is. Each 50L bag will thus cover 5-10 sq. FT (0.5-1sq.M). For a no dig option, spread on the surface and over a season it will work its way into the soil naturally. It can also be added at a maximum of 50% to dilute any potting compost, for use in larger pots, tubs and hanging baskets too. NPK 4:2:6. 100% Vegan friendly, and animal and child safe. 100% peat free and natural. Soil Association Organic Certified for Organic Growers. Supplied as 2 x 40L bag of Peat Free Soil Improver, delivered direct to your door for ultimate convenience and free of charge. *We offer free delivery this compost (but if you add other items to your order then this may include a postage surcharge as they will need to be sent seperately).
