Abstract

The objective is the evaluation of the environmental quality in soils of greenhouses of kidney tomatoes (Lycopersicum esculemium mil) in the San Antonio Sector of the Parish of San Luis Cantón Riobamba. For the evaluation of the sustainability of production systems in the soil, it is essential to have quality indices and indicators that allow determining the environmental quality that will lead to adequate soil management in the long term. Samples of soil and macrofauna were collected in 3 greenhouses. Subsequently, the analysis of the physical, chemical and biological parameters of the soil samples in the soil laboratorios of the ESPOCH and CESTTA was carried out. Once the results of all these parameters were evaluated, the environmental quality of the soil of each of the greenhouses was evaluated with the help of a technical sheet. Finally, it was obtained that all the greenhouses in the soil have a loamy loamy texture and a structure of subangular blocks. It was evidenced that tomato cultivation practices are carried out in a traditional way, without control of soil degradation and Little control of weeds. The owners of the greenhouses mention that they use pesticides in their crops and that they are applied directly to the soil at the end of the day; also applying mostly organic fertilizer tomato at the beginning. An important aspect to mention is that no An abundant macrofauna was presented as expected in relation to time and management, only a number of worms in each of the soil without the presence of invertebrates.
