Natural water used for washing, out and irrigation presents an open nonstationary heterogeneous multicomponent system closely connected with the atmosphere. One should consider such water as a gas-liquid solution where there is a water-gas-solid inclusion equilibrium. When passing the solution through nonhomogeneous magnetic fields several irreversible hydrophysical and hydrochemical processes arise in it which significantly change the natural water properties. One of the most important effects observed in experiments is increasing the number of crystal particles of CaCO₃ which causes reducing the supersaturation of natural water with CaCO₃, shifting the carbonic acid equilibrium and increasing the CO₂ content in water. This water penetrates better through alkaline carbonate soils. The application of the magnetic treaters for leaching saline soil and irrigation treatment allows to diminish the water consumption, to decrease significantly the soil salinization, to enhance moisture supply of plants and to increase the crop yield. The method can positively influence on preservation of water resources of the planet.

Woda naturalna stosowana do nawodnień i odwodnień stanowi otwarty, niestacjonarny, heterogeniczny, wieloskładnikowy system ściśle związany z atmosferą. Można traktować taką wodę jako roztwór gaz-ciecz, w którym istnieje równowaga między fazą ciekłą, gazową i stałą. Gdy taki roztwór przepuścimy przez niehomogeniczne pola magnetyczne, pojawią się pewne nieodwracalne hydrofizyczne i hydrochemiczne procesy, które istotnie zmieniają właściwości naturalnej wody. Jednym z najważniejszych zaobserwowanych efektów w doświadczeniach jest wzrost liczby krystalicznych cząstek CaCO₃, co powoduje redukcję nasycenia naturalnej wody przez CaCO₃, zmianę równowagi kwasu węglowego i zwiększenie zawartości CO₂ w wodzie. Taka woda lepiej przenika przez gleby węglanowe. Zastosowanie urządzeń magnetyzujących do zabiegów przemywania gleby słonej i nawodnień, pozwala zmniejszyć zużycie wody i zasolenie gleby oraz zwiększać pobieranie wody przez rośliny, a zatem i jej plon. Metoda może mieć pozytywny wpływ na ochronę zasobów wodnych naszej planety.

This study investigated arbuscular mycorrhizal fungi (AMF) inoculation and phosphorus fertilizer on growth, productivity and quality of onion grown under saline soil conditions. The experiment was conducted in the Experimental Farm of Desert Research Center, Ras Sudr, South Sinai Governorate, Egypt. Egyptian local onion cultivar ‘Giza 20’ was selected. Treatments were: two arbuscular mycorrhizal fungi (AMF) inoculation treatments [without inoculation (–AMF) and with mycorrhizal inoculation (+AMF)] and four phosphorus supplied treatments (0, 48, 96 and 144 kg P2O5 ha–1). Mycorrhizal inoculation and phosphorus addition affected the plant growth, bulb yield and quality. Morphological traits of plant (height, leaf number, fresh and dry weight), neck diameter, bulb characters (diameter and weight), total soluble sugars (TSS), protein, P content increased, while proline content decreased due to the inoculation of AMF and phosphorus application. Onion inoculated by AMF combined with 96 or 144 kg P2O5 ha–1 gave the highest productivity under saline conditions.

The specific conditions in habitats in the immediate vicinity of roads provide a suitable environment for noxious weeds and invasive species that spread through them to the landscape. Echinochloa crus-galli and Digitaria sanguinalis are problematic weeds of wide-row crops. The field experiment focused on the impact of the roadside habitat salinization on the occurrence, growth and reproduction of these two species. Quantitative vegetative and generative characteristics of the plants were determined. Measurements were carried out at three distances from the edge of the road and on control plots. The results showed that the growth and reproduction of E. crus-galli and D. sanguinalis occur in the period when the values of soil environmental variables correspond to values of non-saline soil according to the criteria for soil salinity assessment. Despite this fact, the average salinity of soil along roadside was still higher than in soil of further distances and we found these levels of salinity to be well tolerated by the study species. Therefore, we conclude that roadsides with the same or higher salt content represent a suitable location for the occurrence and reproduction of E. crus-galli and D. sanguinalis, thus being temporary locations that enable their further spreading to the countryside.

The study objective is to evaluate the effect of mono-ammonuim phosphate (MAP; 0, 10, and 20 mM) applied as foliar application on the growth traits, green and dry yields characteristics, leaf photosynthetic pigments, chlorophyll fluorescence, and leaf contents of nutrients of common bean (Phaseolus vulgaris L., cv. “Bronco”) plants grown under saline soil conditions. To perform this objective, two field trials were conducted at the Experimental Farm of Faculty of Agriculture, Fayoum University during the 2016 and 2017 summer seasons. The obtained results showed that, Na⁺ content was significantly declined, while the all other tested parameters such as growth characteristics (i.e., shoot length, number of leaves per plant, area of leaves per plant, and shoot fresh and dry weights), yield characteristics of green pods and dry seeds (i.e., average pod weight, number of pods per plant, pods weight per plant, dry seed weight per plant and 100-seed weight), leaf photosynthetic pigments (i.e., total chlorophylls, total carotenoids) contents and leaf chlorophyll fluorescence (i.e., Fv/Fm and PI), leaf contents of N, P, K⁺, and Ca²⁺, and the ratios of K⁺/Na⁺, Ca²⁺/Na⁺ and K⁺+Ca²⁺/Na⁺ were significantly increased by the two levels (i.e., 10 and 20 mM) of MAP compared to the controls (without MAP). The two MAP levels conferred the same results for most of the all tested parameters; particularly growth and yields characteristics, with some exceptions. Therefore, results of this study recommend using 10 mM MAP as foliar application to optimize the common bean performances in saline soils.

The aim of the present study was to evaluate the possibility of using a protein hydrolysate, Hemozym N-K 4.5-6, as a component of salinized soil in the cultivation of flossflower (Ageratum houstonianum Mill., Asteraceae). The experiment was focused on the yield and decorative value of A. houstonianum, grown under different concentrations of NaCl and/or Hemozym. Ageratum houstonianum plants were grown in the soil under different NaCl salinity (EC: 0.28 – as control or 3.25 dS m−1 – salt stress) or/and Hemozym dose (0, 0.07 or 0.14 ml kg−1). The results of the experiment imply that A. houstonianum is sensitive to salinity. The application of Hemozym to both unsalinized and salinized soils caused an increase in the yield of the plant organs (roots, stems, leaves, and inflorescence), the number of leaves, and the chlorophyll content without significant changes in the carotenoids. Moreover, an increase in the number and size of first-order inflorescences (heads) as well as more intensive flower color were observed. Thus, it can be stated that the protein hydrolysate studied can be a beneficial component of both salinized and unsalinized soils in the cultivation of A. houstonianum.

Celem prezentowanej pracy była ocena możliwości zastosowania hydrolizatu białkowego Hemozym N-K 4.5-6 jako komponentu podłoża zasolonego w uprawie żeniszka (Ageratum houstonianum Mill.). Założenia eksperymentu koncentrowały się na oszacowaniu plonu i wartości tego gatunku w warunkach różnych koncentracji NaCl i/lub Hemozymu. Rośliny żeniszka meksykańskiego rosły w warunkach zróżnicowanego poziomu zasolenia NaCl (EC: 0.28 – kontrola lub 3.25 dS m−1 – stres solny) i/lub (0, 0.07 lub 0.14 ml kg−1). Rezultaty badań wskazują, że żeniszek meksykański jest dość wrażliwy na zasolenie. Aplikacja Hemozymu zarówno do podłoża niezasolonego jak i zasolonego powodowała zwyżkę plonów poszczególnych organów (korzeni, łodyg, liści i kwiatostanów), liczby liści i zawartości chlorofilu bez wyraźnych zmian w poziomie karotenoidów. Ponadto stwierdzono zwiększoną liczbę i rozmiary kwiatostanów pierwszego rzędu (koszyczków) oraz lepsze wybarwienie kwiatów. Można wnioskować, że zastosowany w badaniach hydrolizat proteinowy jest dobrym komponentem podłoża zasolonego jak i niezasolonego w uprawie żeniszka meksykańskiego.

The aim of the present paper is to test the criteria elaborated in two versions of IUSS WRB (1998 and 2006) on a selection of Polish and German salt-affected soils (SAS). These soils differ morphologically and chemically from typical solonchaks and solonetz of arid regions. The salinity features of natural SAS were described on the second classification level in Histosols and Fluvisols. However, the anthropogenic SAS were classified as Technosols. An evaluation of the WRB classification seems useful, because a new edition of this soil classification system is going to be prepared for the World Soil Congress in 2014. This is why the addition of new qualifiers to Technosols and a redefinition of Hyposalic and Hyposodic qualifiers is proposed.

Celem niniejszej pracy było przetestowanie kryteriów klasyfikacji World Reference Base for Soil Resources na wybranych glebach zasolonych występujących w Polsce i Niemczech. Gleby naturalnie zasolone zostały sklasyfikowane jako Histosols oraz Fluvisols, a obecność specyficznych właściwości chemicznych wyróżniona na drugim poziomie klasyfikacji. W przypadku gleb polskich było to zgodne z wtórnym charakterem procesu zasolenia. Gleby antropogenicznie zasolone spełniały natomiast kryteria dla jednostki Technosols. Otrzymane rezultaty klasyfikacji wykazały dużą uniwersalność systemu WRB. Mimo to wskazane są pewne zmiany w celu lepszego odzwierciedlenia cech gleb spoza stref aridowych i semi-aridowych. W związku z tym zaproponowano dodanie dwóch nowych kwalifikatorów dla jednostki Technosols (Anthrosalic i Anthrosodic) oraz doprecyzowanie definicji kwalifikatorów Hyposalic i Hyposodic.

Carrot production of valuable carotenes, carbohydrate and protein are hindered by elevated salinity levels in many parts of the world. To assess this problem, germination and growth of two carrot cultivars (Daucus carota cvs Jordan and Napoli) were studied in vivo and in vitro under different salt stress concentrations (0, 75, and 150 mM NaCl). Seeds were directly or gradually exposed to these salt concentrations. With elevated salinity levels, significant reductions in growth parameters (dry shoot weight, fresh shoot weight, shoot length, root length, and root number) were observed. Also, significant difference in germination percentage was observed at 150 mM NaCl in both cultivars when compared with control treatment (90% germination percentage in Napoli and 71% in Jordan cultivar). Growth rate, tolerant index, and relative water content (RWC) declined as salinity increased. The 150 mM NaCl salinity treatment significantly reduced the shoot chlorophyll and protein content, but increased carbohydrate content. Lesser impairment by the gradual exposure of seedling to salinity provides an opportunity to study the acquirement of salt tolerance.

Two pot experiments were conducted during the two successive seasons of 2014 and 2015 to study the effect of propolis extract at the rates 0, 6000, 7000, 8000 and 9000 mg/L solution used as seed soaking to spinach seedlings on growth, yield and some chemical constituents of spinach plants (Spinacia oleracea L.) grown under calcareous saline soil conditions. The obtained results indicated that increasing the rates of propolis extract as seed soaking application increased the growth parameters of the treated plants. The best result was obtained by the middle rate (7000 mg/L) as seed soaking in both seasons of the study. The same trend was also observed regarding all studied chemical constituents, i.e. chlorophyll a, b and total caroteniods concentration, anthocyanine, total carbohydrates, total and reducing sugars, total free amino acid, free proline, crude protein, total indoles, total phenols, N, P and K in leaves. Moreover, soaking seeds in propolis extract before planting improved the metabolic activity of seeds through the increase in seed values in total and reducing sugars, total free amino acid, total indoles and total phenols as well as the lowest values of total carbohydrate. Thus, the coincident application of propolis extract at (7000 mg/L) as a seed soaking ingredient is recommended for improving growth, yield and chemical composition of spinach plants and for overcoming the adverse effect of saline conditions.
