Following the advice of Spanish crop advisor Arjan Spaans of Van Iperen, AMX-Ca has been being used at Santini nursery Richard van Schie since last September: "We saw a couple of yellow leaves at the bottom and also some dry leaves. In consultation with my colleague, fertilization specialist Eric Watzeels, I then advised the use of AMX-Ca. We already had positive experiences with it at other companies."Danny Duijvensteijn (left) and Arjan Spaans
At nursery Van Schie experiences are also positive. "We started to try it just once, but after one round of spraying we saw the difference," says Danny Duijvesteijn. "The crop consultant observed the same thing. The flowers looked more vital. The leaves were firmer and greener, and we also did not have to pick leaves anymore. The effect was evident."
Van Schie uses AMX-Ca in addition to its fertilization strategy. Duijvesteijn: "AMX is not an alternative means and there is no alternative for it either. It is an additional means of improving the quality of the flowers. AMX stimulates growth and creates visibly greener and firmer leaves. As a result, the flowers also better withstand transport."
The foliar fertilizer is sprayed together with crop protection products. In the summer it is administered once every two weeks and the rest of the year every week. "We use AMX year round. When the sun shines less and it gets colder, it's time to increase the frequency of every other week to every week," says Duijvesteijn. Consultant Spaans adds: "It is important to administer enough AMX in time. The santinis harvested in the most difficult period, December and January, you must help right from the start. A growing round here lasts about eight weeks, so you certainly need to start spraying every week by early October."
