Abstract

When choosing land for raising a new planting of vegetables or fruit crops, the composition of the soil plays an important role; therefore, the composition of soil is examined, and chemical analysis of soil is made. The culture that we examine is a raspberry planting. Raspberry is amulti-annual plant in the form of a bush or semi-shrub,with more annual roots and with one-year or two-year-old offshoots belonging to the Rosaceae family. Raspberries are irrigated by a drop-by-drop system, because through that system, remediation of soil can be carried out by adding appropriate crystalline fertilizers. Nitrogen (N) is the element with the greatest movement in the soil itself and its content is from 0.05 - 0.14 %. The pH value affects the calcium content in soil. Calcium plays an important role in the hardness of fruit and the sensitivity of physiological disturbance amounts to 1-2.1 %. Phosphorus is important for the fruit properties during storage and amounts to 14.7 - 40 kg / da. Potassium is a major element and plays a major role in producing good yields in fruit trees and amounts to about 14-50 kg / da. When mentioning magnesium, its role is not the most important and amounts to 74.5-221 ppm. The main role of magnesium lies within the ratio of potassium (K / Mg), which should range from 2: 1 to 3: 1. With the obtained soil analysis data, in addition to the climatic conditions, type and structure,which are equally important for raising a raspberry plant, we have a full understanding of the soil processes and guidelines for suitable conditions for growing raspberries.
