Humus: Mixture of plants and other partly decomposed plant parts, mixed with soil to enrich it with nutrients. Humus presents bacterial properties and makes the soil mix more porous. It can be found under deciduous trees or prepared with decomposing leaves. The term humus (or compost) can also be used to define the material formed by decomposition of animal and plant remains; vermicompost (or worm humus) is used to define the mix resulting from worm excrement and the soil used for its production – this mixture is extremely rich in nutrients that enrich it and give porosity to the soil used in plant cultivation.
