Adequate spray deposition on susceptible grapevine tissue is an essential requirement for effective chemical control of economically important diseases, such as grey mould, powdery mildew and downy mildew. The objective of this study was to evaluate the potential of some agricultural adjuvants to improve foliar spray deposition. Deposition quantity and quality was assessed by means of a spray assessment...
The present experiment studied effects of systematic, differentiated mineral fertilisation and liming on the amount of N-NO3-, K, Mg, Ca, Na ions lost from the 0-40 cm soil layer during meadow sward vegetation period as a result of leaching. The highest amount of filtrate was observed in the control object for both series, i.e. without liming and with liming. During vegetation, the level of filtrate...
