Svenska äpplen - hur ligger det till med växtnäringsbehovet?

Sammanfattning: Apples are a popular fruit in Sweden. The production is however low in comparison to the consumption. With a warmer climate in Sweden in the near future it is probable that there will be an increase in the number of apple orchards. With such a potential there are good reasons to investigate the nutritional flow which affects both the environment and the economy of the orchard. In this study, the nutritional flow of nitrogen, phosphorus, and potassium was investigated for four apple orchards in southern Sweden in order to create a nutritional balance and see if there are any risks of nutritional leakage. A survey was also conducted to see whether there are any great differences in aspects regarding the nutritional flow among Swedish apple orchards. No conclusions could be drawn from the nutritional balance as the results were unclear and were based on insufficient information. The result from the survey suggests that there are several aspects that differ among Swedish apple orchards. The participation in the survey was however low and the results from this study are therefore also unreliable.
