a laboratory study based on olfaction
… are pests of economical importance in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. The aim of this …
natural resource management and climate change adaptation and mitigation
… constructions for controlling runoff, improving the establishment of cover crops and practicing soil management which prevents erosion. Very few products are more sensitive to climate change than wine. With changes in climate the Western Cape, South Africa’s main wine region, is …
… achieve this, common plants need to be improved but it also need new potential crops to be developed and introduced (Carlsson et al., 2009). Modern technology like gene engineering is an important tool to achieve these challenges (Carlsson et al., 2011). This work focused on …
… by farmers that cleared large forest areas to create fields for their crops, by the iron industry that demanded huge amounts of wood as fuel and by the forest products industry such saw and paper mills. The reforestation was not properly taken care of. In the year of 1903 the …
Klimatförändringarnas upplevda effekter på lantbruket och olika aktörers åsikter om klimatanpassning
… have positive effects like longer growing seasons and the ability to grow new crops. Some respondents perceive that there are uncertainties about climate change which obstruct climate adaption in the agriculture. According to several respondents information is important to …
a comparison between agroforestry and non-agroforestry
… for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing …
… production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing …
… numbers are needed before the water could be used for irrigation of edible crops or drinking. The most important cleaning step seems to be the anaerobic sequencing batch reactors. No Salmonella was found in any samples but the human pathogen Shigella was found in several samples …
a comparison between agroforestry systems and non agroforestry systems
… farm, semi-structured interviews and seasonal interviews were held and the crops cultivated were recorded, particularly cooking bananas in mixed cropping systems. This study was run in parallel and in cooperation with two other studies, one on soil carbon stocks and one on …
… under bare fallow. The pot experiment that was preformed had four different crops; red clover, white clover, ryegrass and bare fallow and the soil in the pots where taken from the plots with bare fallow in the Önnestad field trial. Free-living nematodes were counted and …
Det finns många olika anledningar till varför man väljer att så mellangrödor. I detta försök har vi valt att fokusera på själva mellangrödan och inte på användningsområdet. Försöket går ut på att undersöka kol- och kvävehalten i oljerättika och maträttika (Strukturator) …
… experimental station, were analyzed using a mixed linear model. For the spring crops barley and oats, the objectives were to examine how subsurface drainage at the drain spacings of 16 m, 32 m and 80 m affects harvest level and optimal seeding date. For winter wheat, the …
soil carbon and yield modelling for crop rotations with rye
… with ley used for biogas production. The yield of food crops from this rotation was relatively low. The spreadsheet model used for simulations in this study is described in the report and can easily be modified and used for other studies, or for getting a rough idea of the yield …
… in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many …
