Compost
Compost is an organic product consisting of a mixture of ingredients used to mulch, fertilise and improve the soil. Compost is commonly prepared by decomposing plant and food waste via a composting process to recycle the organic materials. Compost is used to improve the soil fertility in gardens, landscaping, horticulture, urban agriculture and organic farming.
Digestate
Digestate is the material remaining after the anaerobic digestion of a biodegradable feedstock. Anaerobic digestion produces two main products: digestate and biogas. Digestate is produced both by acidogenesis and methanogenesis and each has different characteristics. The primary use of digestate is as a soil conditioner. Acidogenic digestate provides moisture retention and organic content for soils thatcan break down further, aerobically in soil. Methanogenic digestate provides nutrients for plant growth. It can also be used to protect soils against erosion.
Liquid digestae wa proven to boost bacterial life in soil for home gardening. The Ddigestates application to the irrigation water reduced bacterial diversity within 24–48 h and selectively and significantly stimulated beneficial resident host-associated microorganisms (Pseudomonas putida).[1]
