In 2021, the Soilcom partner Hortiadvise Scandinavia, started two trials with compost. 

The first one was carried out at Johansen Plantenskole, a nursery with seedlings of forestry and shrubs.  In the spring of 2021, compost applied. The objective of the trial is to see if one application of compost is resulting in improvement of the soil structure and quality of the crop. Another objective is to see if application of compost is also effecting the existance of pythium, fusarium and phytophthora in the soil. In different cultures 3 levels of compost were applied: 0, 10 and 50 tonnes of compost per hectare.


The second trial was carried out at Manssons in Brande. A vegetable grower. From the idea that compost could have an oppressive effect on various pathogens in the soil, including pythium and phytophthora. At Månsson, we want to see if the use of well-turned compost from Klintholm I / S can reduce the level of pathogens in the soil already in the season in which it is applied.The compost is a garden park compost, and is applied at the beginning of May this year in a field of coleslaw. In the trial the application of resp. 10 and 50 tons garden compost will be compared with plots without compost. In the autumn, it will be investigated whether there is a difference between the plots with compost and the control without compost. The soil will be analyzed for pythium, fusarium, phytophthora, and rhizoctonia solani.
