- Abstract
Soil microbial communities are a crucial link between soil nutrient availability and plant productivity. They particularly depend on soil organic matter (SOM) content, which is considered one of the main components of soil fertility. But agricultural intensification and the increase in the use of fertilisers of mineral origin in recent decades (to the detriment of the incorporation of organic materials in agricultural soils) have resulted in a continuous loss of agricultural soil quality and fertility, which is considered one of the greatest challenges to addressing global food security. Therefore, a better understanding of the mechanisms driving soil improvement via soil microbiota could result in a sustainable improvement in crop yields. Soils were sampled in 40 intensively managed greenhouses in southeast Spain to understand how SOM influences soil fungal community and how both these factors influence plant development. The values of three out of four growth‐related variables (plant height, aerial dry weight and leaf area, but not root dry weight) in both tomato and cucumber plants showed a positive relation with SOM content and soil fungal diversity. This study concludes that SOM is key for the maintenance of soil fertility in intensive horticulture and that it is linked to the composition and diversity of soil fungal community. Both SOM and soil fungal communities should be considered as essential factors in achieving high soil fertility, and ultimately, to ensure an optimum crop development.
