Compost is an organic product consisting of an aerobic composting process to recycle the organic materials. It consists of a mixture of ingredients used to mulch, fertilise for plant growth and improve the soil structure to increase water and nutrient retention, aeration, and erosion control. Compost is used 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]
