Often in the soils of crop rotations of grain crops, including on black soil, the content of mobile forms of copper, manganese, zinc and other trace elements is low.Improving the efficiency of making micronutrients for grain crops and determining the best ways and doses of their introduction are topical issues that need to be addressed in order to increase the productivity of crops.
Abstract: Aim of the trial Is the evaluation of the impact of two PN applications, in spring, on winter wheat fertilized with KCl at base dressing, four K levels, with respectively 0%, 50%, 75% and 100% of the supposed K removal based on the expected yield of 6,5-7,0 mt/ha.
The winter season of 2016-2017 was quite dry in Spain. A trial that that was conducted by Haifa Iberia compared different fertilization treatments in winter wheat. The comparison was between fertilization with:
