Decomposition of Growth from Grassland after Mulching
Decomposition of Growth from Grassland after Mulching
Abstract (English)
When mulching on grassland or fallow arable land, the vegetation is cut, chopped, and spread in a wide swath in one work step. The material re- mains on the field, where it decomposes. Mulching is a simple, inexpen- sive method and, if applied properly, it is a suitable cultivation measure for many grassland locations and fallow arable land. A decisive factor for successful mulching is the rapid decomposition of the mulched mate- rial because long covering and shading of the grass sod leads to undesi- rable changes in the vegetation. Extensive field trials regarding the de- composition of mulched material served to determine suitable periods for the mulching of typical grassland sites. The results show that the de- composition of mulched material mainly depends on the weather condi- tions, while the type of vegetation and the intensity of chopping are of lesser importance. The modelling of the decomposition of mulched mate- rial allows the remaining mass per area unit to be calculated from the initial mass per area unit, the sum of temperature, and the sum of preci- pitation during the period after mulching. Based on simulation with weather data of a reference region collected over many years, it is pos- sible to estimate the duration of decomposition for varying growth ma- sses and mulching periods. From this, favourable, site-specific periods for the mulching of grassland biotopes are derived. The first grassland growth can be mulched until the end of July/beginning of August, the se- cond growth until the end of September/beginning of October.
