Objective of the course

Introduction of students with problems concerning the application of fertilizers in agricultural production and the effects of fertilization on the individual elements of the environment. Rules of the proper use of fertilizers understanding, for increase the efficiency of fertilization and reducing the negative environmental impact.

Course contents
Lectures:

1. Natural and anthropogenic causes and effects of soil acidification. (2 h)

2. Mineral fertilizers as source of nutrients surplus and undesirable elements in environmen) (balance nutrients management in fertilization rules, methods of describing fertilizer recommendation, nutrients balance and fertilizer recommendation system, fluoride and chlorine, soil solution salinity, air pollution, heavy metals in soil). (2 h)

3. Natural and organic fertilizers and environment pollution (2 h)(air and soil pollution). (2 h)

4. Wastes uses for fertilization and soil improvement and environment pollution (liquid sewages and sewage sludge’s, wastes use for liming, soil pollution by heavy metals and toxins). (2 h)

5. Influence of fertilization on soil solution and surface waters composition (nutrients leaching from agroecosystems, eutrophication of surface waters). (2 h)

6. Influence of fertilization on plant properties. Influence of fertilizers industry on environment (ion balance in plants, nutrients surplus and deficiency in plants, industrial pollution in local and global scale) (2 h)

 
Classes:

1. Calculating of protons load from anthropogenic sources. Protons neutralization. (3 h)

2. Hydrolitic acidity measurement and calculating of lime rates. (3 h)

3. Nutrient balance in field and farm gate scale (computer fertilizer advising). (3 h)

4. Chlorine content measurement in potassium fertilizers. (2 h)

5. Calculating of heavy metals load from wastes use for fertilization (sewage sludge’s, liquid sewages, wastes use for liming). (2 h)

6. Phosphates in water measured by the colorimetric method. Nitrates in water measurement by the potentiometric method. (3 h)

 
Field work:

1. The collecting of surface and drainage water samples. (2 h)
