This study aimed to identify the effects of oxidized brown coal humic acid fertilizer on the relative growth rate of several tree species intended for reforestation. Field experiments were carried out during 2011-2014 at the Research and Experimental Center for Combating Desertification located at the Elsen Tasarkhai station in central Mongolia. The trees studied were Populus sibirica Tausch., Salix ledebouriana Trautv., and Acer tataricum L. The experiment was conducted with concentrations of 2000, 10,000, and 20,000 mg L −1 of humic acid fertilization treatment. Measurement of the relative height growth rate (RHGR) was undertaken for a period of four years. The results demonstrated significant differences between the humic fertilizer concentrations, which varied depending on the species. Compared to monthly RHGR over the study period, the treatment using fertilizers yielded significantly better tree growth. P. sibirica, when treated with 2000 mg L −1 and 10,000 mg L −1 humic acid fertilizers, had significant height growth rates. S. ledebouriana with 20,000 mg L −1 of humic acid fertilzers treatments showed the highest RHGR. In addition, when the humic acid treatments were compared to the control, results showed that oxidized brown coal humic acid fertilizers as an organic fertilizer can have a significant effect on the growth of A. tataricum. The results equally showed that the soil chemical properties EC, CO 2 , NO 3 , and K 2 O were significant among all the treatments compared to control. The effect on P 2 O 5 significantly increased in all the treatments; however, there was no significant effect on pH and Mg among all treatments. Combining the results obtained with reforestation and sustainable land-management practices can help to improve soil organics in degraded sandy soil regions.

“…Therefore, available N from animal manures is considered to have substantial potential and is highly necessary for optimum plant growth in contaminated soils. This essential element is also usually added as a supplement in various types of organic fertilizers, either alone or in combination with inorganic fertilizers 22 . The substantial OM content in the Cd-Leo treatment did not exhibit a commensurate in uence on plant growth performances in this study.…”

The marigolds (Tagetes spp.) in this study, were classified as excluders for cadmium (Cd); however, their leaves also accumulated substantial Cd content. Among the experimental growth media (i.e., control, cattle, pig manure, and leonardite served as soil amendments), pig manure was found to result in significantly increased growth performance for all marigold cultivars, as seen by relative growth rates (119-132.3%) and showed positive effects on leaf anatomy modifications e.g., thickness of spongy and palisade mesophyll, size of vein area and diameter of xylem cells. This may be due to substantially higher essential nutrient content, e.g., total N and extractable P, in pig manure that aided all marigold cultivars particularly the French cultivar which exhibited the highest relative growth rate (132.3%). In the Cd only treatment, cell disorganization was observed in vascular bundles as well as in palisade and spongy mesophyll, which may have been causal in returning the lowest plant growth performances recorded in this study, particularly in the American and Honey cultivars (RGR = 73% and 77.3%, respectively).
