Put food scraps; no meat potatoe bread, mainly vegie, fruit and crushed egg shells into a bucket with lid say 20 litre capacity or more(add manure or chook poo if available) add water up to 3/4 line, stir, replace lid and leave for at least a month....the longer the better! Pour approx 1 to 2 litres from bucket into container dilute bit like a credit raising with 10:1 ratio of water for applying vegie garden and garden plants weekly. Top up bucket with water(best to leave water in sun for 2 hours + if town supply) 20 litres supplies 200 litres of liquid fert. Best to have a couple of buckets depending on useage and to water garden after application. Cheap alternative...
