“…Both salt concentrations (50 and 100 mM NaCl) significantly decreased plant height 39.9 cm and 41.7 cm, respectively compared to HO. Many studies had reported and agreed that salt stress caused similar plant height reduction in watermelon (Yetisir and Uygur, 2009); in pepper (Aktas et al, 2006); in maize (Irshad et al, 2002); in muskmelon (Carvajal et al, 1998); in tomato (Casierra-Posada et al, 2009); in common bean (Beltagi et al, 2006); in red-osier dogwood (Cornus sericea) (Mustard and Renault, 2006); in common bean (Gama et al, 2007). In the study, HA caused an increase in plant heights in both salt treated plants, which were 17% and 9.8% taller in S1HA1 and S2HA2, respectively compared to S1 and S2, but these differences were not significant at the level of α=0.05 (Table 3).…”

The study aimed to determine the effects of humic acid (HA) on seedlings of a salt-sensitive plant, mung bean (Vigna radiata (L.) Wilczek), grown on 50 mM (S1) and 100 mM (S2) NaCl concentrations. In controlled room conditions, mung bean seedlings were planted in pots containing torf and perlite mixture and salt effects were observed. The growth parameters were plant height, number of leaves, leaf area, leaf and stem fresh and dry weights in which all parameters significantly decreased at both salt levels. Nutrient analyses of Na, K and Ca were conducted by flame photometry (FP), and Mg, Mn, Zn were tested by inductively coupled plasma atomic emission spectrometry (ICP-AES), for the above and below ground parts of mung bean seedlings. Both salt treatments increased Na content significantly, however 10 ml addition of HA to those samples (S1HA and S2HA; 50 mM NaCl and 100 mM NaCl, respectively) caused reductions in Na contents of the above-ground parts of mung bean compared to plants watered with only Hoagland-Arnon solutions (HO). On the other hand, in the roots of mung bean seedlings, Na content rose significantly in S2 compared with control, but the amount of Na in S2HA significantly increased compared with S2 treated plants. K content was significantly decreased in both salt concentrations, while SHA1 and SHA2 caused slight increases in both above and underground parts of seedlings. In the experiment, SHA2 increased the content of K, Mg, Ca, Mn and Zn in the root of mung bean seedlings compared with both S1 and S2 treatments.

“…Worldwide, over 50 million hectares of agricultural land have salinity problems, which, when added to the scarcity of water resources, forces us to seek new management perspectives for these soils. This is how different types of amendments and conditioners have been documented for the recovery of saline soils, such as gypsum, organic acids and different types of polyacrylamides, compost, etc., with positive results being reported (3,10,12,20,24). Soil conditioners are naturally or chemically synthesized substances, which can improve soil quality and facilitate plant growth (1,2,9).…”

“…The literature has reported different responses of saline soils to organic matter applications, which aimed to favor the movement of salts. These responses may be physical, such as the increase in coarse porosity and hydraulic conductivity (5,15,18), chemical, due to interactions between the active part of certain functional groups, particularly carboxylic acids with salts (4) and biological, such as improvements in nutrient uptake (N, Ca, P, K, Mg, Fe, Zn and Cu) (3,14,15). Thus, various mechanisms of OM reduce the negative effects of salinity, making it clear that it is a complex system, where different OM fractions can act in different ways, improving physical, chemical or biological conditions and promoting plant growth.…”

“…Although there is a series of investigations related to the effects of the application of amendments on the chemical and physical properties of saline and sodic soils and their effect on crop production (3,9,19), few studies have monitored the electrical conductivity in different soil layers after the application of amendments (26). Many of these studies have been conducted for the remediation of saline-sodic soils under field and laboratory conditions, but the spatial and temporal evaluation of the movement of solutes in the field is difficult, so the soil is generally evaluated in columns and under controllable conditions (13).…”

Preliminary use of a fulvic acid, as a strategy to improve water use in saline soils

et al. 2021

An evaluation of a fulvic acid (FA) was made in a Loam soil, by selecting the best dose to achieve salt displacement under a drip emitter. In trial 1, PVC columns were filled with a loam soil and irrigated with a KCl solution of electrical conductivity (EC) of 12.5 dS m-1. Once the soil solution EC reached the value of the KCl solution, FA doses of 0, 2.1, 5.3 and 10.5 kg ha-1 were applied. The bulk electric conductivity and soil chemical properties were evaluated after 6 irrigation cycles. In trial 2, the same soil salinized with the KCl solution was placed in 0.8 m3 containers. Two irrigations treatments were performed: a control and the best FA dose from trial 1. The displacement of the salt bulb created from irrigation with a dropper in the soil profile was characterized. In trial 1, the dose of 5.3 kg ha-1 reached the lowest EC after the third irrigation. In trial 2, the selected dose reduced EC until 3.75 dS m-1 at 0.3 m depth at the third irrigation, saving 246 L of water compared to control. Additionally, the salinity bulbs were more horizontally extended in the FA treatment. Highlights: Application of FA (5.3 kg ha -1) reduced the water use by 50% compared to leaching carried out exclusively with water. The use of Fulvic acid showed to be an alternative to consider in the recovery of saline soils under drip irrigation when irrigation water is scarce. Little or not residual effect was found after the use of Fulvic acid.

“…In addition, the nature stability of these substances affects carbon and nitrogen cycles and carbon sequestration. Moreover, it can ameliorate the negative effect of salt that would inhibit the plant growth and the uptake of nutrient elements (Casierra-Posada et al, 2009).…”

his study was conducted during the two successive seasons 2016 and 2017 at Baloza district, North Sinai governorate, Egypt. This study is a trail to solve the problems of salinity that impede the sustainable development of horticultural economic activities (even all of the agriculture activities) by improving the productivity of such fruit orchard and the quality of the produced fruits. In this study, two bio-organic materials (humic acid and vermicomposting leachate) used to overcome the negative effects of salinity on mango trees (Keitt cultivar). Three concentrations of vermicomposting leachate (VCL): control (tap water), (VCL)1: vermicomposting leachate at 10% and (VCL)2: vermicomposting leachate at 15% were sprayed on the trees and three levels of humic acid [(HA)0: control (without), (HA)1: 20 ml/ tree/season and (HA)2: 40 ml/ tree/season] added to soil were the main treatments applied to achieve the aim of the work. All treatments were added three times, the first added when growth started, the second was after full bloom and the last added three weeks later after setting. The obtained results revealed that all treatments were very effective in stimulating growth parameters, mineral contents, yield, physical and chemical characteristics of the fruits. In addition, (VCL)2 with (HA)2 increased leaf area, total chlorophyll content, leaf mineral contents (N, P and K), fruit set, fruit retention, fruit weight, pulp weight, pulp/fruit percentage, number of fruits/tree, yield/tree, total soluble solids, total sugar content, ascorbic acid and decreased peel weight and total acidity in the Keitt mangoes cv. Furthermore, increasing humic acid decreased EC, pH, Cl and Na and increased Fe, Zn, Cu and Mn in the soil.
