matter and fungal presence in soils of horticultural crops’, published in the Annals of Applied Biology journal . The research establishes a direct association between the diversity of fungal organisms and the development of crops. The experts have analyzed four variables in cucumber and tomato plants: the increase in the dry weight of the aerial part and of the roots, the area of ​​the leaves and the height of the plant. To achieve the result, the scientists studied specimens in 40 greenhouses in the province of Granada for five years. They analyzed the physical and chemical parameters of the soil and the genera of the fungal communities. In parallel, they evaluated the effect of the soil on plants grown in a controlled environment chamber in pots. In this

way, they detected that a presence of more Palau Email List  than 1.5% of organic matter in the tomato crop soil obtains significantly higher values ​​in the four variables analyzed. “In addition, the height of the plant, the dry aerial weight and the leaf area showed positive and significant correlations with the total number of fungal genera”, indicates Marín. In the case of cucumber, the results were generally similar, except for one issue. “Plants grown on soil with organic matter greater than 3% achieved significantly higher values ​​in plant height, aerial dry weight and foliar area than at 1.5%”, adds the agronomist. The results of the study point to the positive incidence of microorganisms to maintain and improve soil fertility, defined by three components: physical, chemical

biological. “Mineral fertilizers do not return fertility to the soil, it is the organic matter that serves to regenerate them and bring them to a balance where expenses are lower and the enclave remains fertile,” he adds. In the last decades, researchers have detected that monocultures under intensive fertilization with synthetic fertilizers, of mineral origin and without incorporating organic amendments, reduce their yield. For example, greenhouse horticultural production. It is the phenomenon known as floor fatigue or tiredness. “This continuous loss of the quality and fertility of agricultural soil is considered one of the greatest challenges to address world food security”, considers the researcher. The research team continues its work using the harvest
