In the process of humification, lignin unites with proteins forming a lignin proteinate complex. This renders the protein very resistant to microbial attack. Thus, nitrogen in humus is retained and only slowly released. Humus itself under-goes slow decomposition so that in well aerated soils receiving normal additions of organic material, its level remains fairly constant. This slow decomposition is of great practical importance. It provides a means whereby nitrogen, as well as simple mineral compounds, can be stored in the soil and release gradually for plant consumption. Z-Hume also serves very productively when applied in furrow with starter fertilizer. Re-establishing microbial activity is important and is exactly what occurs when Z-Hume is applied at planting.
