Minimum or no mechanical soil disturbance2. Permanent organic soil cover – maintaincrop residues to achieve 30% soil coverTwo main arguments:1. Scientific evidence to support the claims made for CAwas unclear and inconsistent2. CA did not ‘fit’ within the majority of smallholder farmingsystems in Africa3.

EMC standards generally cover the range from 0 Hz to 400 GHz. Currently, however, not all frequency ranges are completely regu-lated. The first important frequency range is the range around the power network frequency, which in Europe is 50 Hz. Most loads connected to the power network are non-linear loads, i.e., they draw a current that does not follow the sinusoidal voltage. Non-linear loads .
