… Sweden. Each cultivar was replicated three times. The studied cultivars were harvested at the 25th of May, 2nd and 7th of June. Four samples, each with an area of 0.03 m2, were cut at ground level within each of the plots. The phenological stage of the grasses was visually …
… operations. Additionally, preclearance as a complement or substitute to the harvester’s handling of small trees was evaluated. The study was conducted in a 32-year old first-thinning-stand dominated by spruce. A factorial block design was used, in which four combinations of …
… and the developmental stage of the crop controlled the 134Cs content in the harvest-mature potato tubers. The highest content was detected in the case of a fallout in the middle of the growing season. In the case of an early fallout, the change in 134Cs content during the …
