“…Humic acid has been reported to stimulate and improve stomatal opening and leaf K content in potato "Golden Delicious" [41], lettuce [42], cucumber [43] and strawberry [44]. Higher K content can be related to the presence of K 2 O in humic acid composition and higher acidity of the solution given the fact that K is absorbed better in alkaline medium [45].…”

The combined application of organic and mineral fertilizers can be a proper way of nutrition management to increase the yield and quality and to mitigate environmental impacts of chemicals and the pertaining costs. The impact of different rates of sulfur-containing humic acid was studied on yield and nutrient uptake of the fruits of olive "Zard" three-year-old trees in a trial based on a Randomized Complete Block Design with three replications in Shariati College of Tehran, Iran. The studied treatment was sulfur-containing humic acid at four rates of 0, 20, 25 and 30 kg·ha Zn contents. All in all, the application of sulfur-containing humic acid at different rates had favorable impacts on quantitative and qualitative traits of olive fruits.

The increase of industrialization, the overuse chemical fertilisers and mining activities are brought about heavy metal-led environment pollution, especially agricultural land. This leads to more boron (B) contamination and accumulation in the soil. This study was carried out to evaluate B uptake from the soil of ornamental cabbage grown as a hyperaccumulator plant under B stress conditions in a controlled greenhouse on plant morphology, physiology, antioxidant enzyme activity the effects of humic acid (50mg kg-1 B + 2% humic acid -HA) and chelate [0.5 g kg-1 chelate (EDTA)] applications. According to the results, especially chelate application significantly increased the B uptake of the plant, and B accumulation was higher in the plant shoot than in the root. However, HA and chelate applications brought out the negative effects of B stress on growth and physiological characteristics and reinforced the increases in malondialdehyde (MDA) content and superoxide dismutase (SOD) and catalase (CAT) enzyme activities. In conclusion, this study shows that HA and chelate additions increase the efficiency of the use of ornamental cabbage to remove excess boron from the soil. According to these results, it is possible to increase the use of ornamental cabbage for phytoremediation purposes, especially with chelate application.
