“…At treatment of 0.5% brown juice, EC (dS m −1 ) and pH were 0.12 and 4.21, respectively; while, at the highest applied rate 10% they were 1.99 and 4.38, respectively. Low pH is not favorable for the development of plants; it reduces photosynthesis due to a reduction in stomatal conductance [55]. This might explain why we found diminished growth of Celosia plants treated at high rates of brown juice.…”

Brown juice is a byproduct of fractionated green biomass during leaf protein isolation. It represents approximately 45%–50% of the total pressed fresh biomass. Disposal of brown juice is a serious issue in leaf protein production due to its high biological oxygen demand and carbohydrates content. The current study aimed to find a possible potential use of brown juice. Therefore, chemical and biochemical properties of brown juice—derived from alfalfa green biomass—were determined before and after fermentation by lactic acid bacteria. Additionally, the growth stimulation potential of fermented brown juice on plumed cockscomb (Celosia argantea var. plumose ‘Arrabona’) plants were tested. Celosia seedlings were sprayed at different rates of fermented brown juice (i.e., 0.5%, 1%, 2.5%, 5%, and 10%) and tap water was applied as control. The results revealed that lactic acid bacteria successfully enhanced the stabilization of brown juice via reducing sugars content and increasing organic acids content. After fermentation, contents of glucose monomers were 15 times lower; while concentrations of lactic and acetic acids increased by 7- and 10-fold, respectively. This caused a reduction in the pH of fermented brown juice by 13.9%. Treating Celosia plants at lower rates of fermented brown juice (up to 1.0%) significantly induced their growth dynamics and antioxidant capacity. Higher values of vegetative parameters were measured in treated plants compared to control. The brown juice treatments caused significant changes in histological parameters as well. The activity of catalase and peroxidase increased in plants that received fermented brown juice especially at low rates. Moreover, an increase in water-soluble protein and phenol was measured in different tissues of plants sprayed with fermented brown juice. Malondialdehyde content was lowered in treated plants compared to control. Fermented brown juice at high rates slightly reduced the amount of photosynthetic pigments; however, this reduction was not reported for low rates of fermented brown juice. These results surely illustrate the potential use of fermented alfalfa brown juice as a growth stimulator for crops particularly at rates below 2.5%.

“…Similar patterns have been detected in Arabidopsis thaliana and in maize (Zea mays) (Wang et al 2011). Anugoolprasert et al (2012) reported that the optimum pH for the development of crab apples was 6.0 owing to anthocyanin accumulation. However, in the present experiment pH values over 7.0 were associated with the strongest development.…”

We established an in vitro system to investigate transcription levels of the RsMYB1 gene expressed in T2 20-day-old transgenic Petunia plants (three independent lines: PhRs1, PhRs2, and PhRs3), and the association between those transcription levels and anthocyanin production at various pH values (3.0 to 8.0) for a period of 10 days. All the lines treated with pH 5.0-7.0 exhibited increased anthocyanin content and delays in growth compared to the wild-type (WT) seedlings. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis confirmed that the enhancement of anthocyanin production in the transgenic lines was due to the upregulation of RsMYB1 transcription at various pH values. The results suggest that pH value can control expression of RsMYB1 which is associated with anthocyanin production.

“…1). The increase in soil pH by addition of biochar resulted in higher plant dry weight by increasing essential nutrient availability to plants (Anugoolprasert et al 2012). The higher base cations in applied biochar increased soil Ca 2+ , Mg 2+ , and K + contents significantly, which also contributed to the increase in plant dry biomass.…”

The forms of phosphorus (P) in animal manure and peat are different from synthetic P fertilizers and will affect soil P fractions when they are used as P amendments. Effects of chicken manure (CMB) and peat (PB) derived biochars (CMB and PB) alone or in combination with P fertilizer (KH 2 PO 4 ) and rock phosphate (RP) on plant/soil health and soil P fractions in an acidic ultisol were examined with greenhouse pot experiments. The total P rate was constant at 120 mg kg −1 in all treatments. Soil P fractions, P uptake, and maize growth were determined after 56 days. Application of CMB combined with P fertilizer or alone significantly increased soil pH, water extractable and relatively labile P, dry matter yield of maize, chlorophyll contents in maize leaves, while decreasing the Fe and Al binding P. Moreover, sole application of CMB and PB showed greater effects than application of P fertilizer alone regarding plant growth and P fractionation. Integration of synthetic inorganic P sources with CMB or sole application of CMB is more beneficial than application of inorganic P sources to improve plant growth and P availability.
