"Bought plantjord give finer plants than homemade soil, according to tests at the university of Gothenburg. But since the purchased the earth tend to be based on peat, it is not necessarily preferable."
"– the Peat carbon where it is located and emit carbon when we dig it up, " says Catarina Sjöberg, associate professor at the university of Gothenburg's trädgårdsutbildning, to Vetenskapsradion."
"She has made scientific comparisons between köpejord and plantjord that her students made according to an old trädgårdsmästarrecept. The torvbaserade köpejorden gave the best seedlings."
"– In the earth grew the plants and was at its finest. But the other two jordblandningarna that we tested also produced fine plants, fine plants, " says Catarina Sjöberg."
"– The purchased earth had a good balance between the various nutrients. The soils that we made was terribly unbalanced."
