“…As a water-soluble component of HA, FA has a low molecular weight; therefore, it more easily promotes the absorption of potassium by plants. At the same time, the carboxyl group and phenolic hydroxyl group of FA react with the amide group of potassium to form a complex (Farid et al, 2018). In this study, the values of SPAD, chlorophyll fluorescence and photosynthetic parameters in the FA180 treatment were higher than those in the FA90 and FA270 treatments.…”

Potassium and fulvic acid (FA) fertilizer applications are two important measures for improving cotton growth. However, there are few studies on the application interactive effects of controlled-release potassium chloride (CRK) in combination with FA on cotton production. To explore the effects of CRK combined with FA on cotton, field experiments were conducted in 2018 and 2019 using a split-plot design. The main plots were assigned to two types of potassium fertilizer – controlled-release potassium chloride (CRK) and potassium sulfate (KS) – while low, moderate, and high FA application rates (90, 180, and 270 kg ha −1 ) were assigned to the subplots. The cotton yield, fiber quality, net profit, soil available potassium concentration, potassium use efficiency, and leaf photosynthesis were markedly affected by potassium fertilizer and FA. The cotton boll number and boll weight in the 2 years and the yield in 2019 were all affected by the interaction between potassium fertilizer and FA. Compared to the other potassium treatments, the CRK × FA180 treatment increased the seed yield and net profit by 4.29–14.92% and 13.72–62.30%, respectively, over the 2 years. The potassium agronomy efficiency and potassium recovery efficiency (KRE) of the CRK × FA180 treatment were also improved by 6.25–30.77% and 3.82–12.78% compared to those of the other potassium treatments. Overall, the FA180 treatment resulted in better cotton growth than that in the FA90 and FA270 treatments. The release period of CRK in the field during the growth period of cotton was longer than that detected by 25°C static water extraction, which increased the soil available potassium content and met the potassium demands over the whole cotton growth period. Therefore, the application of CRK in combination with 180 kg ha −1 FA is the best choice for cotton fertilization.

“…Humic materials are complex aggregates of brown to dark colored amorphous. Fulvic and humic acids are the main parts of humic substances which causes improve soil fertility and nutrients availability, thus plant growth in agricultural crops (Khaled andFawy, 2011, Ali, 2015;Abd-Elrahman and Taha, 2018;Samie et al 2018;El-Naqma, 2020). Potassium fulvate and potassium humate are humic acid and fulvic acid potassium salts, completely water-soluble (Taha et al 2016).…”

O NLY few publications focus on the effect of humic substances plus foliar spraying with molybdenum on plants. Therefore, the objective of this study was to determine the influence of some humic substances (i.e., potassium fulvate and humate as a single treatment or in a combination) and the foliar application of molybdenum element (i.e., 0.0 and 50 mg L -1 as ammonium molybdate) on kidney bean (Phasuolas vulgaris L.;varitety Nebraska) plants. The field trial was carried out in a private farm at Tanah Village, El-Mansoura District, El-Dakahlia Governorate, Egypt during two consecutive growing seasons 2017 and 2018. The experimental design was a split-plot with three replicates. The findings showed that the combined treatment of potassium fulvate with potassium humate under foliar application of Mo at rate of 50 mgL -1 was the superior treatment for vegetative growth criteria, i.e. fresh and dry weights of shoot and plant height, chemical constituents in leaves (i.e. chla, chlb, chla+b), N, P, K , Mo and NPK nutrients uptake at a period of 45 days from sowing as well as yield, i.e. pods and seeds weights and nutritional elements concentration in seeds, i.e. nitrogen, phosphorus, potassium, molybdenum and NPK nutrients uptake at harvest stage of kidney bean plants. While the lowest values of all aforementioned traits were recorded with untreated plants (without both humic materials and Mo). Also, available N, P and K in soil after harvesting kidney bean plants pronouncedly differed due to all studied treatments.

“…One of the promising approaches to increase both P and micronutrient availability in soils is through amending soils with humic acid (HA) (Farid et al 2018). This organic amendment may set P free in soil; hence, increase its uptake by plants (IzharShafi et al 2020).…”

G ROWING maize in calcareous soils requires adequate supply of phosphorus inputs, yet excessive P-applications may affect negatively micronutrients availability in soil, including Zn. Thus, the current study evaluates the ability of humic acid (HA) to counteract the negative effects of applied P on Zn-uptake by maize plants. To achieve this aim, a field experiment was conducted in a calcareous soil (CaCO 3 =268.91 g kg-1) following a split plot design to study the interactions between different P-inputs (100, 125 and 150% of the recommended dose, applied in main plots) and available-Zn in presence and absence of HA (applied in sub-plots at either 2 or 4 kg HA ha-1). Results revealed that increasing the level of P-application raised significantly P availability and consequently its uptake by maize plants; thus, enhanced significantly plant growth parameters and grain yield. In this concern, 125% of the recommended P-dose recorded the highest partial factor productivity values. Likewise, application of HA raised significantly available-P content and improved considerably plant growth and grain yield, especially with increasing the rate of its application. On the other hand, increasing the level of P-fertilizers decreased significantly Zn-availability and uptake by plants; however, in presence of HA, this effect was counteracted. Although, this amendment recorded no significant effect on soil-Zn availability; however, it raised significantly its content in shoots but not in grains. In conclusion, HA improved significantly the productivity of maize grown on a calcareous soil. This amendment not only improved the partial factor productivity of P-fertilizer, but also increased Zn-uptake by maize plants.
