This article is part of a series devoted to discussing strategies for the synthesis of ion-imprinted polymers and molecularly imprinted polymers, their chemical structure and great potential, which may be used in porous material design, analytical chemistry, environmental protection and other areas of science. The presented work constitutes a basis for a better understanding of what porous polymers are, how we can synthesise them and how to foresee their properties, which can be later used in studies of environmental pollution and analytical chemistry.

In Poland, in recent years, there has been a great interest in growing spelt wheat. This is dictated not only by an increasing demand for food with higher healthy properties and unique taste, but also by a possibility of attracting farmers’ attention to this cereal as an alternative crop, with smaller requirements regarding the use of fertilization, as compared with common wheat. The aim of this study was to carry out the assessment of value of some technological characters of grain and flour of spelt wheat depending on different fertilizations with nitrogen (I factor, n=3, 25 and 50 kg N∙ha−1 + control treatment) and foliar application of microelements (II factor, n=4, Mn, Cu, combined fertilization with Mn and Cu + control treatment). Based on the performed study, it was found that fertilization with nitrogen, microelements and their interaction had, on average for years, a significant effect on the values of technological characters. Introduction of 25 kg N·ha−1 caused an increase in the value of falling number, whereas total protein content, wet gluten content and sedimentation value increased as a result of increasing nitrogen rates up to a level of 50 kg·ha−1. Of the variants of fertilization with microelements, the highest values of the analysed baking indices were found in the effects of combined foliar application of copper and manganese.
