Description and goals

The main goal of the subject is the understanding of behaviour of nutrients in the soil, their uptake by plants and the relationship with the environment. Suitable nutrition of plants plays a very important role in the crop development, in the formation of yield and in the quality of agricultural products. The classes are mostly focused on the definition of soil fertility and factors playing an important role in the soil fertility formation and on the cycles of macro and micro elements in soils affecting their immobilisation and losses. The importance of soil fertility for the plants´ availability of nutrients as well as disorders in the element uptake are discussed, too. Methods of soil tests of main parameters of macronutrients and techniques for recommendation of their rates applied in organic and inorganic fertilizers are practised in laboratories and seminars including a comprehensive project of nutrient management. 

Lectures topics

1.Introduction to soil-plant and the environment mutual relationship.
2.Plant composition, element uptake by plants.
3.Conditions affecting element availability for plants.
4.Soil fertility, soil testing, yield response.
5.Distribution of nutrients among main soil phases.
6.Sorption and desorption of nutrients.
7.Uptake of elements by plants, nutrient transport.
8.Nitrogen cycle, transformation of N in soil, uptake by plants, losses.
9.Availability of phosphorus for plants, P uptake and P assimilation.
10.Balance of sulphur in the environment, importance of S for plants.
11.Potassium, magnesium and calcium, uptake of elements by plants.
12.Iron, manganese and zinc in soil and their uptake by plants.
13.Zinc, copper and molybdenum in soil – plant cycle. Deficiency of nutrients in plants.
14.Adverse effect of toxic elements.
