“…Compost is the intermediate form of decomposition which contains humic substances and partially decomposed organic matter [2]. The humic substances are present in almost all soils in small amounts, in the form of potassium humate, potassium fulvates and humins [3]. Naturally occurring humic substances from low grade lignites and leonardites are the best fertilizer ingredients, use or organic fertilizer leads to risk of xenobiotic compound [4][5][6][7].…”

Humus is the stable form of added crop and animal residues. The organic matter after a long-term decomposition process converts into humic substances. The naturally occurring humus is present in less amount in soils of the arid and semi-arid regions. The addition of commercially available humic acid can, therefore, contribute to improving soil health and crop yields. The present study was conducted to evaluate the effect of potassium humate, applied through soil seed dressing, on cotton productivity and fiber quality attributes. Seed dressing with potassium humate was done at the rate of 0, 100, 150 and 200 mL kg−1 seed while in soil potassium humate was applied at the rate of 0, 10, 20 and 30 L ha−1. Results showed that the combined application of potassium humate by seed dressing and through soil application improved the soil properties, productivity and fiber quality traits of cotton. All levels of soil applied potassium humate (10, 20 and 30 L ha−1) performed better over seed dressing in terms of cotton productivity and fiber quality attributes. Among the soil application rates, 20 L ha−1 potassium humate proved better as compared to other rates (0, 10 and 30 L ha−1). Higher soil application of potassium humate (30 L ha−1) showed depressing effects on all the traits studied like the reduction of 12.4% and 6.6% in Ginning out turn and fiber length, respectively, at a seeding dressing of 200 mL kg−1. In conclusion, potassium humate seed dressing and soil application at the rate of 200 mL kg−1 and 20 L ha−1, respectively, is a better approach to improve cotton productivity. Soil potassium humate should not exceed a rate of 20 L ha−1 when the seed dressing of potassium is also practiced.

“…Potassium humate (K-humate) is a natural material that can improve soil physical and chemical properties and nutrient dynamics (Kumar et al, 2013;Abd-All et al, 2017). Humic acid consist on reactive functional groups with pH dependent properties, including carboxyls, phenolic, and alcoholic hydroxyls (Alvarez-Puebla et al, 2005).…”

Potassium humate (K-humate) is a promising natural resource to improve yield and nutrient uptake by crops. A field experiment was conducted to assess the efficacy of Khumate application in combination with chemical fertilizers on enhancing yield and nutrient uptake of maize grown in a calcareous soil, western of Nile Delta, Egypt in two successive summer seasons (2015 and 2016). The Khumate was applied at a rate of 15 kg ha -1 along with an increasing rate of chemical N, P and K fertilizers, varying from 0 to 125% of the recommended dose. The results indicated that grain yield of maize significantly responded to application of K-humate. The results also indicated that the computed optimum grain yield of 7463 kg ha -1 without application of K-humate can be obtained by applying 98% of the recommended dose of chemical fertilizers. However, in the presence of K-humate, the optimum yield of 8310 kg ha -1 can be obtained by applying about 73% of the recommended dose of fertilizers. Nutrients uptake responded linearly to the increasing rates of chemical fertilizers, without or with K-humate application. However, the rate of increase in the presence of K-humate was substantially higher than that recorded at its absence. The difference in the increase of nutrients uptake was the highest for P, then N and K in the presence of K-humate. This study suggests that K-humate has the potential to increase crop yield, nutrient uptake and reduce the amounts of applied chemical fertilizers in calcareous soils.

“…Consequently, humic acid reduced water stress effect on soil physical properties. Whereas, humate application reduced water stress effect on soil chemical properties through increase the resistance to the increasing in EC values, where humic acid acts as a chelating agent to metal ions (Kumar et al 2013). However, adding humic acid in humate salt form caused increasing on pH value, whereas at the end of two season pH values return to normal level according soil buffer effect.…”

Wheat (Triticum aestivum L.) is widely cultivated in the Mediterranean zone where plants generally suffer from water stress during heading and reproductive stages. This research was carried out in a field experiment at Shandaweel Agricultural Research Station during the two successive growing seasons 2015/2016 and 2016/2017 using water treatments (water stress and well watered) and humic acid (soil application) and silicon (foliar application) on some wheat cultivars (Gemmeiza 11, Shandaweel1, and Sids 12). The application rate of humic acid and silicon was 2Kg/feddan and 150 ppm, respectively. The results showed that wheat cultivars had a significant effect on the all studied traits. Normal irrigation gave the highest significant mean values of all studied traits in both seasons. Treatment by silicon or humic acid effected significantly in all the studied traits in both seasons as compared to control treatment. The interaction between irrigation treatments and wheat cultivars were significant or highly significant for most of the studied traits in both seasons. Moreover, under normal irrigation, there are no changes in some chemical and physical properties of soil, however, there are slightly changes in the physical properties of the soil and a significant changes in the chemical properties under water stress condition. Using silicon didn't affect or played any role on soil properties under normal or water stress condition, whereas using humic acid reduced water stress effect on soil properties.
