Strawberry mulching with plastic mulch becomes more and more popular. Application of plastic mulch reduces weed distribution, ensures better water usage and reduces nutrition application due to better uptake of elements by crops. The aim of this study was to estimate the influence of black plastic mulch on soil biological activity in the strawberry field. The experiment was carried out at the Pūre Horticultural Research Centre in 2011 and 2012. An intensity of soil respiration, activity of dehydrogenase and cellulose were used as indicators of microbial activity in the soil. The highest dehydrogenase activity and soil respiration was observed in the middle and at the end of summer, when soil moisture was 12 – 15% and average daily temperature was 12 – 20 °C. Cellulose activity was higher during the first strawberry growing year. Using of black plastic mulch can increase soil biological activity, but further investigations are necessary for obtaining more feasible results.
