… two forms of chlorine are only indirectly related through variables as soil moisture or organic matter. The storage of organic chlorine when a depth of 40 cm was taken into account was seven times the storage compared to an earlier study where only the top-soil was sampled. The …
Carabidae) i hävdade strandnära gräsmarker :
… A high structural heterogenity is providing conditions for many niches. Most moisture dependent carabids show a similar life cycle. They are all adults at the same time of the season, in late spring. The season in moist areas may be shortened by a longer frozen period so that …
… harvest. Sometimes for example, it can be necessary to harvest, although the moisture content in the kernel is a little too high in order to manage to keep a high falling number. In such cases, it may be necessary to accept higher costs for drying the seeds. The thousand-kernel …
… 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 …
… risk a water stress on the plants and leaks of nitrogen. The results off soil moisture sensors accuracy is that the usual sensor is good enough to decide when it’s time to start irrigation and the amount of water. The accuracy of the results depends on how well they suits the …
… now use non-plough tillage. Advantages with this method are higher soil moisture and that compaction due to tractor tracks is reduced. This will compensate for a small yield loss that can result from using this cultivation method. The future of the oilseed crop looks bright. OSR …

… 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 …
… were selected so that site index, vegetation type, ground conditions, soil moisture, m.a.sl., exposition, etc., were as equal as possible. In each stand 20 sample plots were inventoried. Each sample plot was represented by 1 meter in the scarified track in the seeded stands …
… in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated. The results showed a distinct edge effect. The …
AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry …
… the larger four-storied building shows that the humidity is below the upper moisture limit for the plasterboard to be built into a wall construction. No visual damage was spotted on the boards and no connection between the humidity and the weather was observed. The study shows …
… rate or set to achieve a desired concentration in the exhaled gas. To achieve moisture and right temperature in the exhaled air, a humidification chamber with water with heating elements was used. A connection to the humidification chamber with non return valves was used to …
… 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 …
