The suitability of the seedlings determines the outcome of mechanical planting

 When we start discussions with a new customer, we ask for information about the plants to be used. This is so that we can ensure the technical functioning of the planting machine. 

We usually ask to go to the nursery to examine the seedlings and carry out a drop test. This test is very simple - we drop the seedling from a height of 1.5 m and if the substrate remains in the pot then the seedling is of good quality. 

On the other hand, it is important to check the shape of the roots, if the roots are twisted or they branch outwards the trees will grow slower. Air roots and "prickly" roots are a source of interference to the machine's operation.

The shape of the stem is also crucial, a twisted or curved stem is not suitable for mechanical planting.

We may sound demanding, but the machine performs many functions at the same time. Even a single disturbance slows down the operation and the simplest way is to put poor-quality seedlings in the ground manually.
