The influence of adding soil, alternating turning frequency, fleece-covering, optional irrigation and roofing on the rotting process of dairy cow/pig-manure was monitored in a practical trial with triangular windrows. They were monitored chemically (water-content, pH, conductivity, organic substance, TOC, N total, NH4-N, NO3-N, K total, P total, C/N, specific oxygen uptake rate, humic substances and plant growth test) and sensually. On the basis of correlations between chemical and sensual results an assessment-matrix for the rotting process should be designed. There were clear differences between the treatment methods regarding the rotting process. Unfortunately, it is unclear to which part the influences are the result of the treatment methods or clearly detected inhomogeneity in the initial manure. Adding 5 – 10 vol.-% soil resulted in improved crumb-development, less potassium loss, less temperature development and less salt content and higher plant growth rate. Higher turning frequency resulted in slightly higher carbon- and nitrate-losses and reasonable higher salt-, potassium- and phosphorus-losses. Covering with fleece resulted in higher temperature and water content reduction, reasonably less salt losses, slightly less nitrogen losses and more development of humic substances. Roofing resulted in less temperature development, less water content reduction, less substance- and nutrient-losses, less development of humic substances and higher nitrate development. Optional irrigation was not necessary during the whole trial. There were not enough correlations found between the chemical parameters and sensual monitoring results to take them as a base for designing an assessment-matrix for the rotting process.
