Vázání uhlíku ve stínících dřevinách na agrolesnických kávových plantážích v Nikaragui
Hrubešová, Karolína
The bachelor's thesis presents the results of calculating the amount of sequestered carbon in shading trees and coffee plants on three selected agroforestry coffee plantations in the department of Matagalpa, which are located at an altitude from 880 m above sea level to 1400 m above sea level. The territory of the selected plantations belongs to the ecosystem of tropical montane cloud forest. The highest stock of carbon in the above-ground and underground biomass of shading trees was at the Selva Negra plantation, located at an altitude of 880 – 1,300 m above sea level, it was 48,7 ± 1,5 Mg ha-1, in addition coffee plants was 2,5 ± 0,22 Mg ha-1. At the La Dalia plantation at an altitude of 950 – 1,050 m above sea level, the above-ground and underground carbon stock in shade trees was 33,36 ± 1,94 Mg ha-1 and 2,3 ± 0,5 Mg ha-1 in the coffee plant. The total carbon stock from aboveground and belowground biomass of shade trees at the La Esperanza plantation, at an altitude of 1,350 – 1,400 m above sea level, was 28,8 ± 2,6 Mg ha-1. In coffee plants, the total supply was 1,9 ± 0,02 Mg ha-1. Funding options were proposed from the information found. If the studied plantations were interested in fi-nancial gain from traded carbon, they could each individually be entitled to a one time contribution: USD 2,656.47 (La Eperanza), USD 4,430.34 (Selva Negra), USD 3,085.66 (La Dalia).
Vliv rozdílných typů zástinu na vybrané vlastnosti plantáží Coffea arabica v okolí města Villa Rica, Peru

Coffee belongs to very important crops in the world and it is traditionally grown in agroforestry systems. During the five years the four coffee plantations with different type of shading were studied in the foothills of the Peruvian Andes. The highest amount of carbon was found in the plantation shaded dominantly by Eucalyptus spp., followed by Pinus spp., Inga spp. and non-shaded site. The microclimatic characteristic measurement shows that shading reduces the mean air and soil temperatures and increases the air humidity, compared to the non-shaded site. It was recorded drier soil conditions at the shaded site. At all plantations, coffee variety and age had a significant effect on Coffee Leaf Rust incidence. The value of the timber stored in shade trees varied significantly. There were different results for different shade trees species (from 2% to 72% of the annual income from coffee production).
