… the seed, but it’s also important with coarser soil at the surface to keep the moisture in the ground. The summery of the interviews shows that the uses of furrow presses has increased in the middle of Sweden, but are still common in Skåne, Harrowing in autumn are common in all …
För lager-, industri- och kontorsbyggnader
… in roof structures for industrial buildings has been investigated from a moisture standpoint. The analysis shows that without a functioning vapour barrier the moisture content in the construction increases over time, which leads to increased heating costs. The conclusion of this …
… the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the …
… To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste. Therefore the landfill is dependent on precipitation input, although when the landfill is covered, rainfall can no longer infiltrate the landfill and hence irrigation …
… 4.6-5.3 in the composts, with no significant difference between treatments. Moisture content varied between 62-94 % in the compost substrate, with no significant difference between treatments. C/N ratios in the substrates were relatively high at the start (C/N: 37-45) and …
Skogen är en förnyelsebar energikälla som möjliggör för ett minskat beroende av fossila bränslen. Ur ett politiskt perspektiv minskar såväl klimatpåverkan som beroendet av importerad energi från oroliga delar av världen genom att ta tillvara skogsbränsle lokalt. I Sverige är …
… parameters in relation to the duration of the pig tillage and also the soil moisture content at the time the pigs were allotted each small plot. Results showed that pig treatment was significantly better for reducing couch grass than the ploughed treatment, but on the other hand …
… most important factors are temperature, access to oxygen, nutrients and the moisture content of the bark. In average the dry matter loss is about 3.5 % per month over a six month period. The losses are significantly higher in the beginning of the storage period but later on …
en biologisk bekämpningsmetod mot ogräs
… The explanation, nearest at hand, is that the peat stores and contributes moisture and nutrients to the plants. The plant species that produce the highest amounts of biomass were Medicago lupulina and Trifolium repens Undrom. It should be pointed out that this investigation has …

… with grain, to find the most economic alternative. It is not common that moisture content is below 14% when harvesting grain in Sweden. To store the grain safe it has to be preserved in some way. I have described some of the most common systems for preserving grain in this …
… the farms had used round bales as storage system for their silage and that the moisture content of the forage was above what is recommended. The majority of the farmers spread slurry as manure on their fields. Most of them wilted their herbage before loading and about one third …
… stands. In one of the stands a time study and a measure of stump biomass and moisture content was done. A Hyundai excavator (23.5 ton) with a Pallari stump-head was used for the stump lifting and a Timberjack 1710 was used for the extraction of stumps. Time needed for lifting …
I papperstillverkning ställs det krav inte bara på kvalité och kvantitet utan också att stickprov från produktion utförs och tas hand om på ett korrekt sätt. Från det att ett stickprov tas ut och undersöks på brukets laboratorium kan en del källor till förändringar på …
… material. Samples were also taken from the studies for determination of moisture content. The production per time unit (ton/h) was measured and how much of the time that the machine was working effectively. The number of crane cycles that were used for feeding the machine was …
… was the amount of stumps per hectare. Also lifting cost, hauling cost and moisture content had a significant impact on the total system cost.The lifted stump volume (m3f) was on average 35% of the harvested stem-wood volume (m3fub).
