Aim of the study: Industrial soilless cultivation of plants is associated with the formation of leachate, which may pose a threat to the environment. Their management is an important issue due to the limitation of the dissipation of ingredients in the environment, but also the limitation of the use of water, which in this type of cultivation is a key element not only in terms of quantity, but also quality. Material and methods: The variability of nutrients in the leachates was analyzed for everbearing strawberry variety San Andreas cultivated in soilless conditions on gutters. Results and conclusions: The chemical composition of leachates was characterized by a high dynamics of changes in the content of elements (nutrients) during the growing season. These changes are caused by the amount of nutrients given in the nutrient solution and the frequency of fertigation due to transpiration and the amount of plant biomass conditioning the amount of components consumed. The chemical composition of the leachates from the strawberry plantation does not preclude their re-use in the recovery process.
