Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump Harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which Harvesting methods that have been tried in Sweden and how they worked.

The corn plant came to Europe with Christopher Columbus in the 14th century and have ever since bin cropped here, but corn haven?t bin very common in Scandinavia until recently. The mainly use for this crop silage but even corn for grain is cropped in Europe. Corn for grain is a common part of feed in beef and chicken farming. In Sweden corn for grain is pretty rare but almost 1000 hectares are used for this crop, Lantmännen Sverige is the biggest buyer of corn at the moment.

Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased Harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the Harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the Harvested volume of Lodgepole pine over time.

This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary Harvest was collected from eight farms and samples from the first regrowth Harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both Harvests were ensiled in completely airtight silos, but samples from the second Harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.

The purpose of this thesis was to create a strategic/tactical road access plan. This was done by designing an analytical method which gives the road manager a template to create long-term road access plans. The analytical method will help to identify and appraise roads to be upgraded and give information when it is time for building new roads. The study method involved developing an analytical method. The method was comprised of five main parts: the Harvest plan, analysis of the road network, transport costs, quality and storage costs and finally, identification of investment alternatives.

Projektet Curiosity > Harvest handlar om självhushållning som en del i det moderna livet i staden, och mer specifikt biodling i den urbana miljön. Dels ur perspektivet att knyta samman stadsmänniskan med matproduktionen och förutsättningarna för livet, och dels ur perspektivet att sätta fokus på den ekologiska hållbarheten i samhället i stort. Projektet tar ett större grep över hur ett system för biodling i staden skulle kunna se ut, och inbegriper en kartläggning av staden utifrån biets perspektiv, ett system för material- och kunskapsdelning mellan människor och en ny bikupa. Systemet baseras på ett tänkt nätverk med namnet Curiosity > Harvest, och fungerar som en plattform vilken besitter kunskap, material och kapital och underlättar för människor i staden att ta steget till att bli biodlare. Kartläggningen visar Göteborgs växtlighet enligt en generell kategorisering, och föreslår även en mer detaljerad inventering av den, ofta bortglömda och bortprioriterade, flora som bina är beroende av i sitt pollineringsarbete.Biodling är ett ämne som binder samman alla skalor i ett designarbete, från stadsplanering till produktdetaljer, och sätter det mänskliga ansvaret, arbetet och skördens belöning i samband med hela den biologiska livscykeln.Resultatet av arbetet är ett designat förfarande, och produkterna bildar det toolkit som visar en serie exempel ur ett sådant förfarande..

Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. In an experiment carried out during the 1990ies the retention of 134Cs in potato haulm and the transfer to the tubers were studied. The experiment was carried out during three consecutive years. The plants were cultivated in pots under field conditions and the artificial deposition was sprayed directly onto the potato haulm at different times during the growing season.

Food insecurity is a great problem worldwide and Ethiopia is one of the sub-saharan countries that are suffering from poverty and food insecurity and a large part of the population are living in a state of undernourishment. To reduce these problems, a successful horticulture production can be an important factor. Compared to other crops, fruit production in Ethiopia has not been a large part of the agricultural sector. However, the demand on the domestic market is increasing as well as the production for avocado and mango. To increase food security it is important to focus on ways to decrease post-Harvest losses of food products and not only have the productivity of agriculture in focus.

This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every Harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.

During the autumn 2009, a 15 hp degree project was accomplished. The objective of the study was to describe different equipment alternatives, suitable for fresh market apple Harvest. A field study was conducted during the Harvest period to evaluate the efficiency (kg / person/ hour), using the different equipment. Four different systems are described in the study; Pick-ing-bag, Picking-train, Pluk-O-Trak and the Conveyor Harvester. The information about the systems is based on interviews with growers together with previous studies.

All arable land in Sweden need a proper drainage for an effectively agriculture to take place. Of all arable land in Sweden, about 50% is naturally drained and 50% need artificial drainge. More than half of the tile drained area is in need of new drainage or renewed drainage. A good drainage improves farming and crop growth and increases the opportunity to achieve a high and safe Harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage. In this paper, two trials with three drainage distances, performed at Lanna experimental station, were analyzed using a mixed linear model.
