… have increased steadily over time. The most common regeneration methods are planting and natural regeneration. Previous studies (Jansson, 2004) shows that it is primarily forest owner's commitment and ambition that will determine how successful the rejuvenation will be. There is …
hur påverkar användandet av fungicider utnyttjandet och inlagringen av kväve i höstvete?
… risk of nutrient loss from agricultural land. The results from genotype and plant protection trials often show constant nitrogen content in the grain, although the yield has been increased. Results from such experiments are therefore processed in order to confirm this and show …

… different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate …
evaluation of methods, microbial activity and agronomic implications
… the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic …
Plant tRNA isopentenyltransferases (tRNA-IPT, EC 2.5.1.8) have two roles, modification of tRNA and contribution to cytokinin synthesis. tRNA-IPT is among the best studied of the tRNA-modifying enzymes, but little biochemical information is available and none for the plant …

Hemp is an ancient cultivated plant that came to Sweden in the 1st to 2nd Century and was particularly interesting for use for food, clothing and building materials. Over time, other applications have been developed for hemp, e.g. in energy and health products. Interesting new …
… areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen. The purpose of this study …
en undersökning av kanteffekter i några av östersjöregionens skogar
Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific …
… and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water …
Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold …
… funktion är att tillväxten påbörjas så att normal utveckling sker efter plantering. Vattenbrist är ett vanligt förekommande problem vid nyplantering av vedartade växter vilket leder till problem med etableringen. Etableringsbeskärning innefattar alla beskärningsåtgärder som …
… and high costs for medical drug treatments. Within Swedish research, a natural plant substrate, PYLOS, has been developed, which in laboratory tests and a clinical study, has been observed to inhibit adhesion and growth of H. pylori in the gastric and intestinal mucosa. The …
Jämförelse mellan mätmetoderna extraktion, inkubation och jonbytesmembran (PRS-sond)
… with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used …
… resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high. Perfluorinated …
