MOLYBDENUM DEFICIENCY IN YOUNG LETTUCE AND TOMATO PLANTS
The Dutch vegetable growers obtain their potting soil from suppliers specialising in composing potting soil. In the western part of the Netherlands the potting soil is often made of a mixture of low-moor and high-moor peat to which sand and fertilizers are added. It is known by experience that dressings of trace elements get more important as the percentage of high-moor peat in the potting soil increases. In the propagation of lettuce, tomato and some other vegetables especially the trace element molybdenum is of importance.
