Crops and greenhouses

In modern farming the main jobs are mechanised: tractors, combine harvesters and other machines are used. Machinery means the set of tools and means used to create material goods. Farm machines are grouped by the work they do: tillage (ploughs, harrows, cultivators), fertiliser spreading, sowing seeds and planting seedlings (seed drills), plant care (cultivator, duster, sprayer), harvesting (combines) and first processing of produce (cleaning and separating grain). The machine operators must know the machines and the conditions for growing plants and keeping animals. Children do not drive a tractor or combine, do not approach or climb on a working machine; they watch only from the safe place shown by the teacher and the operator.
