Soil physical evaluation of the efficiency of addition of composts to soils by laboratory experiments Additionally to long‐term field experiments a laboratory method was tested for evaluation the physical efficiency of addition of composts to soil. The parameters maximal water holding capacity (MWK), bulk density (TRD), and total pore volume (PV) were determined under reproducible conditions for compost‐soil‐mixtures in comparison to equivalent mixtures of soil with standard‐peat‐litter. The ratio of the coefficients of regression for compost‐soil‐mixtures to those for standard‐peat‐litter‐soil‐mixtures is the so‐called equivalent of standard‐peat‐litter (TMÄ). The efficiency of changes of soil physical properties due to the addition of compost to soil is characterized by TMÄ. |
