“…It was further explained that it is possible that in the structure of humic substances there are hormone-like substances, which are directly involved in photosynthesis, respiration, protein synthesis, and other enzymatic reactions [53]. Application of HA into the soil can also increase the population and activity of microorganisms, as well as improve the rhizosphere, which is accelerated by the presence of root exudates [54,55]. This allows plant roots to explore a wider volume of soil, while supporting plant adaptation to suboptimal soil conditions that have low nutrient content and lack of water.…”

Humic acid (HA) has been reported to increase plant growth and crop yields, as well as improve soil fertility. However, the potential utilization of HA extracted from various organic waste composts as organic amendment in suboptimal soils has not been studied in depth. The experiment used a two-factor Completely Randomized Design (CRD) with three replications. Four types of HA were used, namely bagasse HA (BHA), water hyacinth HA (WHA), market waste HA (MHA), and commercial HA (CHA). It also comprised of four doses HA i.e., 0.05, 0.10, 0.15 and 0.20% (of soil on w/w base). The results revealed that fluctuations in soil pH and nutrient release with the HA application had a variable quadratic response pattern. Organic carbon increased by 17%, while total N and available P decreased by 5% and 38.6% during the last weeks of incubation. The HA application could improve the growth response and nutrient uptake of maize significantly. CHA0.20% was the best interaction treatment which had the highest average value on dry weight and NPK uptake, which were 98.0 g pot-1, 178.8 mg plant-1, 27.4 mg plant-1 and 216.9 mg plant-1, respectively. The scanning electron microscopic (SEM) showed that HA could increase in the length and density of maize root hairs. Furthermore, the HA application significantly increased pH, CEC, C-organic content and availability of soil nutrients.

“…The chemical characteristics of artificial H-LPs regulate the metabolism of microbes and plants to affect the soil carbon reservoir (Wei et al, 2021;Yang et al, 2021). A study by Tang et al (2021) revealed that artificial H-LPs promoted carbon sequestration in black soil by stimulating microbial activities for binding CO 2 , thereby increasing nutrient availability for crop growth. In addition, artificial H-LPs can also enhance photosynthesis to transform more CO 2 into organic matter (Tang et al, 2022).…”
