“…Mixtures of substrates 1:1 (v/v) were homogenized and set up in 0.5 L pots (n = 12) using RRG, some 320 g DW of substrate, and each of the above amendments were applied in their crushed form. We selected the amendment doses, following recommendations found in previous studies where incorporation of feedstocks in similar proportions into a mine soil (Tandy et al, 2009) or a contaminated sediment (Mattei et al, 2017) were found to be efficient in promoting plant growth. The four treatments were as follows (1) ericaceous compost + red gypsum (Ec), (2) white peat + red gypsum (Wp), (3) pine bark + red gypsum (Pc), and (4) Miscanthus straw + red gypsum (Ms).…”

The increasing production of wastes that are landfilled might contribute to sources of potentially toxic elements; this is the case of residual red gypsum tailings, a byproduct of titanium dioxide extraction. Revegetation of such a site is essential, and Mn phytoextraction may render the operations economically profitable. This study aimed to apply phytomanagement techniques for increasing the plant development, tailings revegetation and an optimal Mn phytoextraction using silver birch, the most abundant plant species on this site. To enhance the nutrient availability from the tailings, amendments that reduce the pH, i.e., pine bark chips, Miscanthus straw, white peat, and ericaceous compost, were mixed with residual red gypsum and birches were allowed to grow for 3 months. The pine bark chips and ericaceous compost led to a maximum decrease in pH, allowing the accumulation of up to 1400 mg Mn kg −1 dry matter in the leaves silver birch leaves. However, some nutrient competition was found in the pine bark treatment, which halved biomass production as compared to control. Further amendment addition may be needed to take advantage of the pine bark capabilities as a soil conditioner and Mn solubilizing treatment in residual red gypsum.

Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems

Decreasing arable land, rising urbanization, water scarcity, and climate change exert pressure on agricultural producers. Moving from soil to soilless culture systems can improve water use efficiency, especially in closed-loop systems with a recirculating water/nutrient solution that recaptures the drain water for reuse. However, the question of alternative materials to peat and rockwool, as horticultural substrates, has become increasingly important, due to the despoiling of ecologically important peat bog areas and a pervasive waste problem. In this paper, we provide a comprehensive critical review of current developments in soilless culture, growing media, and future options of using different materials other than peat and rockwool. Apart from growing media properties and their performance from the point of view of plant production, economic and environmental factors are also important. Climate change, CO 2 emissions, and other ecological issues will determine and drive the development of soilless culture systems and the choice of growing media in the near future. Bioresources, e.g., treated and untreated waste, as well as renewable raw materials, have great potential to be used as growing media constituents and stand-alone substrates. A waste management strategy aimed at reducing, reusing, and recycling should be further and stronger applied in soilless culture systems. We concluded that the growing media of the future must be available, affordable, and sustainable and meet both quality and environmental requirements from growers and society, respectively.

“…Those authors reported that excessive alkalinity of fly ash, exceeding the level optimal for appropriate plant growth, may result in inhibition of their development. Another interesting finding was also connected with a lack of an advantageous effect of compost on seed germination and root elongation, particularly since literature data [25] stress the advisability of such an additive. A probable cause for the weak positive effect of compost on plants manifested in the results of the biotest according to the PN-EN ISO 11269-1:2013-06 standard, was connected with its short-term exposure in the soil (3 days).…”

Short-term biotests were used to determine the effectiveness of the use of compost and fly ash in the stabilization of heavy metals in contaminated soil. For this purpose, in two independent experiments, either compost (3:1) or fly ash (1:1) were added to soil contaminated with heavy metals. To assess seed germination and root elongation of Sorghum saccharatum L., Lepidium sativum L., Sinapis alba L. after three days a Phytotoxkit test was used. Seedling emergence and biomass yield after 21 days were evaluated. Obtained data indicate better practical applicability of the seedling emergence test thanks to the longer duration resulting in more reliable conclusions provided in that test. A short, 3-day test did not confirm any effective stabilising role of theapplied additives. Sorghum saccharatum L. turned out to be most sensitive to the altered soil conditions, while Lepidium sativum L. was most tolerant.
