“…There are already several works which investigated the role of arbuscular mycorrhizal fungi combinations with biochar plant pathogens, and usually reported that biochar increased the density of arbusular mycorrhiza (Elmer, Pignatello 2011;Lecroy et al 2013;Akhter et al 2015) and plant growth promoting bacteria (Saxena et al 2013). However, very few works have included biological control agents (Postma et al 2013), such that additional known agents like Trichoderma harzianum and commercial bacillus strains can be tried. Another aspect worthy of research involves whether, in the presence of biochar, doses of fungicides and other pesticides in plant nurseries can be reduced.…”

The increasing demand for soilless substrates and rising environmental concerns about the use of non-renewable resources such as peat has led to the search for alternative constituents of growing mixtures for containerized plants. In this report we reviewed the works concerning biochar as constituent of growing media, targeting its influence on plant growth and plant disease. Biochar mostly has positive or neutral influences on plant growth compared with peat media when present in concentrations higher than 25% (v:v). However, studies of biochar influence on plant disease reveals that while lower concentrations (≤1%) of biochar often suppressed several diseases, higher concentrations (≥3%) were mostly ineffective or induced plant disease. For use as horticultural peat replacement, it is recommended that biochar feedstocks and concentrations be standardized and the potential effect of biochar on plant disease be considered, so that growers can rely on consistent and reproducible biochars for desired effects.

Peat moss has been a standard carrier of inoculum for experimentation and in agriculture. Peat moss is, however, a non-renewable resource. Alternatively, biochar could serve as an inoculum carrier. Here, we tested the effect of biocharbased seed coatings as a carrier for the phosphoroussolubilizing Pseudomonas libanensis inoculum, on corn growth after soluble and insoluble P addition. The survival of P. libanensis was determined based on the measure of colony-forming units from samples of four inoculated guar gum-based biochar coatings and was compared to peat. Storage experiments were performed on inoculated biochars for 22 weeks at 25°C and on coated corn seeds for 16 weeks at 4°C. Seed coatings were prepared with inoculated and uninoculated biochars (100 seeds treatment −1 ), and effects of these treatments are reported on indices of seed germination after 7 days. A greenhouse experiment investigated the effects of the inoculated and uninoculated biochar seed coating on corn plants. The parameters measured from the greenhouse-grown corn plants were germination, fresh weight, dry weight, height, root length, basal stem diameter, leaf area, chlorophyll content, and tissue phosphorous. Our results show that corn plants grown from seeds coated with a biochar from hardwood feedstock are 2 to 10 g heavier than controls and that controls are 4 to 26 % shorter than the plants grown from biocharcoated seeds, where soluble phosphorous is applied.Moreover, corn seeds that were coated with a biochar produced from softwood feedstock germinated more quickly, based on the speed of germination index. Overall, we show that a biochar-based seed coating can benefit sustainable agriculture by carrying P. libanensis and enhancing the growth of corn, but according to parametric statistical tests, it does so without increasing the phosphorous content of the plants.

Medicinal plant cultivation in Controlled Environment (CE) is increasing in the context of the new findings concerning the abiotic stress factors manipulation that leads to a significant increment in bioactive substances. Pathogen control is a vital part of the cultivation system, therefore the study was focused on biological methods of controlling a frequently occurring disease, by inoculating the sterile substrates specific in hydroponics, with the beneficial organism. Hypericum perforatum seedlings were inoculated with Fusarium oxysporum and with Trichoderma spp. The results showed that the method of inoculation had a significant effect on the success of the biological control. The plants treated with Trichoderma spp. had a two-fold increase in foliar biomass and better development of roots than the plants inoculated with the pathogen. Morphologically there were no significant differences, with some notable exceptions. The health status of the seedlings inoculated with the pathogen showed signs of the disease, even in the presence of Trichoderma spp. Finally, determinations of Volatile Organic Compounds (VOCs) at the root level showed that the biotic stress was considerable higher in the rockwool substrate that increased the secondary metabolism giving new perspectives in the cultivation of medicinal plants in CEA.
