“…Also shown in this Table is a decrease in soil bulk density with saline water W2, W3, in second and third soil depths. These results fall in line with findings of (Li et al, 2020) who found the same trend. These results could be due to soil salinity which increase aggregates of particles and decrease soil bulk density (Bless et al, 2022).…”

Afield experiment was conducted to evaluate the effect of two compounds of potassium humate and silicate, combined with compost to decrease the harmful effects of water salinity on potato crop yield and quality, also, the soil available nutrient NPK. The main plots were assigned for the irrigation treatments; 0.5 (W1), 2.25 (W2) and 5.7 ds m -1 (W3). The sub-plots treatments were; F0 (without compost applying), F1 (compost applying to soil), F2 (compost applying to soil plus foliar spraying by potassium silicate solution (10 cm 3 .L) ), F3 (applying compost to soil plus coated tubers with potassium silicate, F4 (compost applying to soil plus foliar spraying with potassium humate) and F5 (compost applying to soil plus coated tubers with potassium humate) . The findings demonstrated that the majority of vegetative growth characteristics, tuber quality and tuber yield were impacted by increasing the salinity of irrigation water in both seasons. Spraying potato plants twice with potassium humate or silicate solutions had a notable positive impact on all of the studied characteristics. Comparing to the control treatment, results showed spraying potassium silicate had a high significant influence on growth characters, yield and yield components of potato in both seasons. It could be concluded that, spraying potato plants twice with potassium silicate solution in the presence of the applied compost to the soil ( F2 ) is the most efficient treatment for reducing the harmful effects of irrigation water salinity on potato and yield quality, and improving the available nutrient levels, NPK, in the soil

“…Therefore, winter irrigation is a widely effective measure to treat soil salinization. The optimal irrigation amount for winter irrigation in northern Xinjiang is still guided by experience rather than by research, and the leaching would occur [44]. This phenomenon also exists in southern Xinjiang.…”

Drip irrigation systems are becoming more and more mature and are now widely used to improve crop yield and nitrogen use efficiency in Xinjiang, NW China. However, it is not known if leaching is occurring or not and whether leaching will harm the water environment following N fertilization and drip irrigation. The purpose of our study was to estimate the leaching volumes, nitrogen losses, forms of nitrogen losses, and nitrogen loss coefficients under different N fertilization, P fertilization, K fertilization and irrigation regimes. A long-term field experiment was conducted from 2009 to 2015 in Baotou Lake farm in Korla City, Xinjiang, with drip-irrigated cotton (Gossypium hirsutum L.) being grown under different N fertilizer and irrigation regimes. The treatments were designed comprising 0 N, 0 P, and 0 K with an irrigation of 480 mm as the control(N0P0K0W480) and the following three other treatments: (1) 357 kg N·hm−2, 90 kg P·hm−2, 0 kg K2O hm−2, and irrigation of 480 mm (N357P90K0W480); (2) 357 kg N·hm−2, 90 kg P·hm−2, 62 kg K·hm−2, and irrigation of 420 mm (N357P90K62W420); and (3) 240 kg N·hm−2, 65 kg P·hm−2, 62 kg K·hm−2, and irrigation of 420 mm (N240P65K62W420). The results showed the following: (1) the leaching volume was determined by nitrogen fertilization, phosphorus fertilization, and the irrigation amount. In general, the leaching volume was highest under treatment N357P90K0W480. (2) The nitrogen loss was highest under treatment N357P90K0W480. (3) Nitrate nitrogen (NO3–) was the main form of nitrogen lost, followed by ammonium nitrogen (NH4+). (4) The annual nitrogen loss coefficients followed the order of: N357P90K0W480 > N357P90K62W420 > N240P65K62W420 > N0P0K0W480, with values of 0.85, 0.55, 0.30, and 0, respectively. The leaching volume, nitrogen loss, nitrate nitrogen, ammonium nitrogen, and annual nitrogen loss coefficient were lowest under the N240P65K62W420 treatment, except in the N0P0K0W480treatment. These results demonstrate that optimizing the management of water and nitrogen (N240P65K62W420 treatment) can effectively reduce nitrogen losses under drip fertigation and plastic mulching.

“…Moisture is important for freezing resistance in alfalfa. Soil moisture has a buffering effect on the soil cooling rate because of its high heat capacity and thermal conductivity and this can mitigate the damage caused by drastic changes in temperature during winter (Li et al, 2020). When alfalfa overwinters, its degree of frost resistance might be affected by soil water deficit caused by seepage or evaporation.…”

“…Because there are not sudden changes in temperature, cryogenic stress is relatively light. This buffering effect can mitigate damage from sudden large changes in air temperature, thereby improving the overwintering survival rate (Sun et al, 2004;Li et al, 2020).…”

Background: Freezing temperatures are a limiting factor hindering the survival of alfalfa (Medicago sativa L.) through winter. Soil drought also damages alfalfa crowns and can affect their regeneration. Therefore, it is important to determine the effects of cold, dry conditions on alfalfa to develop effective water management strategies in winter. Methods: Cold, dry conditions were established in the laboratory and the freezing tolerance of crowns was compared between the alfalfa cultivars ‘WL440HQ’ and ‘ZhaoDong’. The degree of freezing tolerance was estimated on the basis of relative electrolyte leakage and semi-lethal temperature. The effects of cold, dry conditions on alfalfa crowns were determined by investigating the rate of water loss and the concentrations of soluble sugars (which function as cryoprotectants) and betaine and proline (which function as osmoregulation substances). Result: Compared with crowns of ‘ZhaoDong’, those of ‘WL440HQ’ showed a higher water loss rate in cold, dry conditions and were irreversibly damaged and their freezing tolerance was severely affected. In comparison, crowns from ‘ZhaoDong’ showed a lower water loss rate and lower relative electrolyte leakage under cold, dry conditions and their freezing tolerance was not significantly affected. The higher water loss rate and lower freezing tolerance were the direct causes of death of ‘WL440HQ’, the cultivar with a higher fall dormancy score. In cold, dry conditions, the content of proline, an osmotic regulation substance, increased in response to soil water deficit and may have improved the ability to withstand freezing temperatures by preventing rapid water loss. In addition, sucrose, fructose, galactose and stachyose contents in the crown increased under cold, dry conditions and may have enhanced freezing tolerance because of their function as cryoprotectants. The results of this study indicate that maintaining soil moisture within the range suitable for the growth of crowns is important for the successful overwintering of alfalfa.
