“…Similar results were obtained by Breś and Ruprik [16] and Breś [29]: the pH of the drainage waters from tomato cultivation on rockwool and coir substrate increased by one unit in relation to the dosed medium. The low pH in the Carbomat substrate was also observed by Dyśko et al [25] in their earlier experiments. The optimum pH in the root zone for most crops in soilless cultivation ranges from 5.5 to 6.5 [31].…”

“…Altadena F1 were cultivated in a soilless system using slabs with mineral and organic growing media, as follows: (i) rockwool Grotop Master (Grodan), (ii) coir substrate (Coconut), (iii) organic growing mats made of lignite-2.5 to 5 mm fraction (Carbomat), (iv) mats containing a mixture of organic wastes (sawdust, sheep's wool, flax shives and crash brown coal) named Biopot. The detailed characteristics of Carbomat and Biopot substrates were described by Dyśko and Kaniszewski [24] and Dyśko et al [25], and the basic physico-chemical properties of the used substrates are presented in Table 1. Tomato seeds were sown in mid-February.…”

The aim was to determine the suitability of various substrates for application in a closed system of soilless tomato cultivation, based on the potential fitness of drainage waters from these substrates for recirculation. Four substrates were used: rockwool, coir substrate, lignite substrate (Carbomat) and biodegradable organic substrate (Biopot). Tomato plants grown in these substrates were fertilized with the same amount of nutrient solution, containing the same concentration of nutrients. The characteristics of drainage water from these substrates were analyzed during cultivation. The highest amount of drainage water was collected from the lignite substrate Carbomat. However, these leachates showed good properties for further recirculation: low electro conductivity and turbidity, high nutrient content, moderate microbial load with high population of Trichoderma fungi, and being beneficial for plant growth. Moreover, Carbomat produced the highest tomato yield compared to other substrates. This indicates that this organic substrate is an efficient alternative to rockwool and its drainage water may be reused in a recirculation system. On the contrary, the drainage water from the Biopot substrate showed the worst qualities: high pH and low EC, low concentration of nitrate nitrogen and phosphorus, very high turbidity and a high number of microorganisms. These parameters do not qualify Biopot drainage waters for reuse.

“…It contains many organic substances, among others, and it is a very rich source of humic and fulvic acids [27]. Lignite has good physical properties due to highly condensed organic matter, it is sufficiently porous, absorbs water well and maintains a stable homogeneous structure [28][29][30], and moreover it is a good absorber of mineral components necessary for plant functioning [27,30,31]. According to Kwiatkowska [28], lignite is a sustainable organic material, which can be used in agriculture and greenhouse crops.…”

“…According to Kwiatkowska [28], lignite is a sustainable organic material, which can be used in agriculture and greenhouse crops. Currently, the interest in generating energy from coal is decreasing in favor of renewable energy sources, while at the same time there is an increasing interest in a diverse use of lignite in agricultural and horticultural crops [28][29][30].…”

Effect of Re-Used Lignite and Mineral Wool Growing Mats on Plant Growth, Yield and Fruit Quality of Cucumber and Physical Parameters of Substrates in Hydroponic Cultivation

et al. 2021

In hydroponic cultivation of vegetables with a solid substrate, mineral wool predominates. The pro-ecological policy and consumers’ expectations cause an increase in interest in organic substrates, which, when properly used, are less harmful to the environment. The aim of this study was to determine the effect of reusing lignite substrate in hydroponic cultivation on the growth, yield and quality of cucumber fruit and on the physical parameters of the substrate. The greenhouse cucumber cultivar ‘Mewa F1’ with semi-long fruits and smooth skin was used for the study. The plants were grown in the ‘Carbomat’ lignite substrate and ‘Grotop Master’ rockwool in two cycles. In cycle 1, new growing mats were used, while in cycle 2 the same growing mats as in cycle 1 were used again. In the hydroponic cultivation carried out on mineral wool and in the lignite substrate, both in the new and the reused substrate, the cucumber obtained mostly similar plant growth parameters and fruit color. Cucumber grown on the new mineral wool had a higher number and weight of fruits, which were characterized by a higher content of β-carotene and lutein compared to fruits from plants grown in the new lignite substrate. On the other hand, the reused lignite substrate resulted in higher cucumber yields and fruits with higher firmness and higher carotenoid content compared to cucumber grown on reused mineral wool. At the same time, the content of dry matter and sugar extract in fruits obtained from plants growing in the new and reused lignite substrate was higher compared to fruits grown in mineral wool. Both new and reused lignite substrate were characterized by very low plant-available water content. In contrast; the air and water holding capacity of lignite after cultivation did not change as much as that of mineral wool.

“…The study on lignite as a medium in soilless cultivation of tomato showed that, under hydroponics tomato plants produced highest early marketable and total yield when grown in lignite media and this was not significantly different from the marketable yield obtained under coir pith (Dysko et al, 2015). Now a day, in Kerala, more people from urban areas are showing interest towards modern techniques in agriculture.…”
