ABSTRACT: During the production of petroleum and gas a by-product, known as
congenital water, is obtained, which varies in composition depending on the
geological formation from which it is extracted. In the industrial
process its composition is modified and then it is known as “produced water”.
These waters can contain high concentrations of mineral salts that can
potentially be used for crop fertilization. The aim of this study was to
evaluate the effects of the application of produced water on the mineral
contents of the plants and levels of BTEX and TPH in the fruits of greenhouse
tomato cultivation. The produced waters used were derived from gas producing
zone of Sabinas-Piedras Negras in northern Mexico. These waters were analyzed
according to NOM-143-SEMARNAT-2003. Waters from three different stations,
(Buena Suerte, Forasteros and Monclova 1), were mixed with fresh water to
obtain the treatment waters used. As a control, we used a complete Steiner
solution. The results showed that the produced waters modified the absorption
of essential minerals in tomato plants; it
was observed that the mineral concentration in plant tissues was highest in the
control plants, except for Na, in which the plants irrigated with produced
water had the highest concentrations. The treatments with produced waters
also affected negatively the root length, leaf dry weight, stem dry weight,
number of fruits per plant, and the dry weight of the fruits.
