ORTEGA-TORRES, Adrián Esteban et al. Potassium acrylate hydrogel as a substrate in cucumber and tomato cultivation. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.6, pp.1447-1455.  Epub 11-Out-2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v11i6.2222.

Agriculture is the basis of food, it develops in soil and hydroponics. Hydroponics is explained as crops without soil, in nutritive solutions, in the case of tomato and cucumber it is in substrate. Substrates have increased productivity, with efficient use of water and fertilizers. If agriculture consumes 70% of water and spending 30% is fertilizers, the objective of this work was to use potassium acrylate hydrogel for its ability to reduce the loss of fertilizers, such as reserving water, allowing to maintain tomato production and cucumber. The research was carried out in Querétaro in 2017. Different saturation capacities of the hydrogel were evaluated for its properties, the mixture of substrate and the yield of tomato and cucumber, finding significant differences.
