It's well known that the basic condition for halomorfic soils formation is appearance of ascedent saline ground water rising in both, arid-semi arid regions, as well as existence of one season high temperature such as in Vojvodina ("Slatinas" of Banat and Backa). The precioius technological procedures and instruction, relared to selection and choicement of the experimental datas and results, have been implemented in order to verify applied metodes and procedures of halomorphic soils desalinization. The analysed and adopted experimental fields in Banat and Backa were anticipated as the regions of complexive amelioration of Slatinas, extended near by the natural and artificial water resourses (Danube, Sava, Tisa etc.). Evaluations of Pedogenetical process, as well as forming of our soils and the soils where the basic experiments have been established are rather similar. The soils formed by the alluvial deposites after big rivers streams flooding are concerned.

“…Among the most important of these are soil-texture, mineraloglcal composition, previous history (or structure), organic matter, gypsum content, lime content, and the type of bases on the exchange complex. These factors have been discussed more or less adequately by a number of workers [1,6,7]. Lime and gypsum and other soluble soil-minerals are beneficial in tending to maintain soil-permeability as in the case of the Hanford, Reagan, and Cajon soils (see Fig.…”

Data are presented for five western soils showing their permeability to Riverside tap‐water after preliminary leaching with waters of various percentages of sodium. Although the tendency for high‐sodium water to reduce soil‐permeability has been known qualitatively for many years, few data are available to indicate the magnitude of the change that occurs. The data indicate: (1) There is no sharp break in the permeability‐curves as the percentage of sodium in the waters is increased. (2) Permeability decreases greatly when the salt‐concentration is reduced following percolation with high‐sodium water. (3) Other factors also greatly modify permeabilities, that is, all soils do not act alike. (4) Under field‐conditions it is the absolute permeability which governs soil use and productivity. Since soils react differently to the same water, it is incorrect to give a precise percentage of sodium above which irrigation‐waters will cause trouble in this respect. Indicating a range of percentages would seem to be preferable practice. (5) Soils high in organic matter have higher permeabilities than normal soils when irrigated with waters of low‐sodium percentage, and vice, versa with waters of high‐sodium percentages.

“…To ameliorate such soils, long-term studies have recommended using several methods-either singly or in suitable combinations-such as utilizing water, special crops, chemical amendments, organic amendments, electric current, phytoremediation, and tillage (De'sigmond 1924;Kelley and Brown 1934;Agarwal et al 1979;Gupta and Abrol 1990;Oster et al 1999). Ghafoor et al (1986) mainly suggested the application of certain amendments to salt-affected soils that can either provide sufficient Ca 2+ externally or help in the solubilization of native calcite.…”

Effects of torrefied wood chip and vermicompost application on vegetation growth and nutrient uptake in the Saemangeum reclaimed land

et al. 2020

Background: In reclaimed land, the growth environment for plants may be unfavorable and the initial establishment and growth of seedlings could be limited because of low nutrient and water availability. Fertilization and control of understory vegetation that competes with seedlings may be of help in ameliorating soil physical and chemical properties, resulting in better seedling growth and reclamation success. However, the amount of nutrients understory vegetation absorbs in this ecological process has been rarely studied. Thus, we aimed to investigate the effect of soil amendment on biomass production and nutrient uptake by weeds in the nutrient-poor reclaimed area. We applied three levels of torrefied wood chip (TWC; 0, 2.5, and 5 Mg ha −1 ) and two levels of vermicompost (VC; 0 and 2.7 Mg ha −1 ) as soil physical improvements and organic soil amendments in reclaimed land in the Republic of Korea, with Populus euramericana used as the crop tree.Results: TWC did not influence weed biomass, but 2.7 Mg ha −1 VC significantly increased weed biomass by 21% compared to 0 Mg ha −1 VC treatments. Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sodium (Na) concentrations in weeds were the highest in control, but there was no statistical difference among treatments. However, VC treatment did marginally increase nutrient uptake in weeds, especially P, K, Ca, and Na. No treatments influenced crop tree height. Conclusion:We conclude that VC can be used as an organic source of nutrients in reclaimed soil and that weed management is necessary to increase treatment effects on crop trees in this salt-affected reclaimed land.
