06 Mar Global warming is transforming plant-soil interactions
Changes in temperature and the nature of precipitation can radically transform microorganisms in the soil. This, in turn, affects plant growth and may reduce yield.
Thousands of types of microorganisms live in each gram of soil; they interact strongly with each other and with plants. At the same time, each of them has their preferred climatic conditions. Accordingly, climate change is beneficial to one and to the detriment of others. The plants and soils of the Mediterranean basin, where the vast majority of olives in the world are grown, will undoubtedly be affected, as the climate in Spain is getting hotter and drier. Scientists understand that the interaction of soils and plants will change in the near future, but, unfortunately, they cannot predict exactly how. It is clear that climate change will force trees and plants to look for more favorable conditions in the north and in the mountains, and the same thing will happen to soil organisms, but not at the same time. Such a shift in plant zones can affect the productivity of organic olive groves, where a changing climate will affect soil microorganisms, but the vegetation cover will basically remain the same. Olive farms, however, are not likely to be affected, as they are equipped with irrigation and fertilizer to produce a uniform crop every year.
