Analýza bilance organické hmoty v zemědělském podniku
Šimor, Ján
This bachelor thesis is focused on the determination and analysis of organic matter balance in soil after crop´s harvest. An experiment was realized at conditions of agricultural enterprise Agrosystém spol. s r.o., Dolné Voderady, which is located at west of Slovakia, in the region of Piešťany. Evaluation of crop residues and grains (resp. beet roots) were gathered from winter wheat, spring barley, oil-seed rape, corn and sugarbeet. All the information was statistically assessed, compared with a special literature and dated into tables and graphs. Based on the results we found out, that average amount of organic matter is 5.38 t dry matter.ha-1. This amount is sufficient because at 1 hectar of soil is decomposed 3.5 - 4.5 t dry matter of organic matter annually. Among of grown crops, the biggest amount of crop residues is given by corn 7.557 t dry matter.ha-1. In next chapter of the results were calculated harvest indexes. Among of the grown crops, the highest harvest index was calculated at sugarbeet 0.808. Among of the grown cereals, the highest harvest index was calculated at spring barley 0.728.
