Management practices performed at orchards have a direct impact on soil quality and health and whence on soil long term productivity. However, little is known about the specific effects of pesticide use and microplastics in the soil. Several orchard operations may have a positive impact in the soil fertility. However, the use of organic and inorganic fertilizers and the accumulation of pesticide residues and microplastics may affect negatively both the human and the ecosystems health. This work intends to evaluate the influence of fruit production in soil contamination with microplastics and pesticide residues, with a special focus on copper, manganese and zinc as parts of fungicides. The field work will be conducted in peach and almond orchards from the Portuguese region of Beira Interior, which is the main region of peach production and where, in recent years, a growing investment in almond production is being witnessed. This work will be conducted from July 2021 to June 2025.
