In this research, the test parcels from for different locations, where the alfalfa variety Banat ZMS II is cultivated, were included. The aim of this abstract is to establish the content of macrobiogen elements (N, P, K) in the soil, i.e. fertility of test soils and their attendance in the dry mass of the cultivated alfalfa. The results from the agrochemical analysis of soils from the test parcels in v. Saraj (Skopje), v. Radusa (Skopje), v. Jegunovce (Tetovo) and v. Kodzilari (Veles) have indicated different quantities of the same examined macrobiogen elements, i.e. their different fertility. The examined macrobiogen elements (N, P, K) in the dry plant mass of the sown alfalfa on aforementioned location, have showed their different value in dependence of the degradation of soil, with all the same, whereby and from their amount proportion in the soil solution. The contents of N, P and K in the dry mass of alfalfa leaves and stems, is also significantly different, which points at their diverse dynamics on uptake and accumulating from distinct parts of alfalfa as forage culture.
Keywords: macrobiogen elements (N, P and K); soil; alfalfa; dry mass; dynamic; uptake; accumulating
