The amount of nutrients such as carbon, nitrogen, phosphorus, calcium etc. present in the soil at any given time is referred to as

A definite amount of living material present at each trophic level at a specific time is called a standing crop. It can be measured as biomass or a number in a unit area. The nutrients which are necessary for growth such as carbon, phosphorous, calcium, etc. are present in abiotic components such as soil and are known as standing state. Mineralisation is the process by which inorganic nutrients are released into the soil by the degradation of humus by microbes. Hence, the answer is standing state.
