Abstract
By seed surfaces according to the information the Federal Bureau of Statistics and the Institute of Statistics Republic of Srpska of the total area under vegetables potatoes occupies 57% sowing area, so that after the corn and wheat, potatoes the most important agricultural plant in Bosnia and Herzegovina. Most are lighter types of land - permeable, loose, sandy-humus and sandy-clay ground with crumb structure, rich in mineral and organic matter, with favorable water – air characteristics. Does not match his tough swampy lands with a high level of underground water. Tolerate acid soil reaction, and the optimum pH is 5,4-6,5. Given that the area of Tuzla canton mainly acid soil with pH values from 4.5 to 5.5 made the production of a sample on the plot that had a pH value of 4.6 as a material for the reparation of land or quality of calcification was Fertdolomit in order to increase in pH, after you apply Fertdolomit analysis has found that the increased pH value to 5.8. Calcification is a measure of repair of chemical properties of soil, primarily reducing its acidity, ie. bringing the pH value to the optimum level for the cultivation of certain plant species calcium use of fertilizers. At the same time, this measure of the repair water-air, mechanical, physical and biological properties of soil. Reflected in the potatoes plant in four different variants: the control, with the use of 40 t / ha of manure, the use of 40 t / ha manure and NPK 7:20:30 400 kg / ha and the use of manure 40 t / ha, NPK 7:20: 30 in the amount of 400 kg / ha with supplements Fertdolomit in the amount of 3 t / ha. The results reflected a big point to the importance of calcification in the production of potatoes.
Highlights
Potatoes are the fourth largest crop in the world today, after wheat, corn and rice in terms of total production
Calcification significantly increases the yield of potatoes
Calcification increases the yield of potatoes, and has a positive effect on the cultivation of subsequent crops in the crop rotation
Summary
Potatoes are the fourth largest crop in the world today, after wheat, corn and rice in terms of total production. It is produced worldwide on an area of 19 million hectares, and the average yield of tubers is 16.5 t / ha [1]. In order to systematically implement the fertilization strategy and achieve optimal tuber quality, it is first necessary to organize and systematically control the fertility of the soil for production areas where it is planned to grow potatoes. It is necessary to establish, in accordance with the technical and technological possibilities, the manner, quantity and time of its application
