“…Available P reduces as soil pH and salinity increase (Guangming et al, 2017). Results showed that groundnut yields of Hypoma 2 cultivar on saline soil in Lamongan were 69% (fresh pod) and 173% (dry pod) higher than in Tuban.…”

“…High N volatilization in high salinity reduces the amount of nitrogen fixed into soil and also N uptake by the roots from the soil (Osuagwu and Udogu, 2014). Total N in the soil also relates to activity of urease enzyme in the soil (Xie et al, 2017), and activity of this enzyme deceases as soil pH and soil salinity increases (Guangming et al, 2017). This indicates that N fertilization has an important role in increasing groundnut yield on saline soil, but the efficiency is very low because of high soil pH and Reseach on increasing N efficiency on saline soil is still needed.…”

Groundnut cultivation on saline soil facing complex problems associated with high electrical conductivity (EC), toxic effects of Na cation, imbalance nutrients, and N and P deficiency. Objective of this research was to determine optimum rate of N and P fertilizers for groundnut on saline soil. The trial was conducted on saline soil in Lamongan (EC 8-15 dS/m, pH>8.0, low N, high P) and Tuban (EC 8-16 dS/m, pH>8.0, low N and P) during dry season year 2017. Treatment consisted of two factors, and the combinations were arranged in a completely randomized block design with three replications. The first factor was four N fertilizer rates (0, 23, 46, and 69 kg N/ha), and the second factor was four P fertilizer rates (0, 36, 72, and 108 kg P 2 O 5 /ha). Results showed that nitrogen fertilization had no effect on plant height, number of filled pod and plant stand, but improved chlorophyll content, increased100 seed weight, harvest index and yield. Phosphorus fertilization had no effect on all parameters observed, except on 100 seed weight and plant stand. The yield response to N fertilization was linear and quadratic, depending on the location. The optimum N rates was 62-69 kg N/ha. The results indicated that N fertilization had more important role than P fertilization for increasing groundnut yield on saline soil, although the growth did not improve.

“…Generally speaking, the level from which inhibition appears is rather varied, both from the aspect of enzymatic response to individual salts as such, and in comparison of different sites and their soil horizons. Besides proteases, there are other enzymes sensitive to the presence of salts in soil, for example ureases and catalases [16]. Many authors, such as Saviozzi et al [9,[17][18], report that salts reduce the activity of enzymes.…”

Salinization of soil has a negative impact on the activity of microorganisms and thus leads to disturbances in the cycling of nutrients in the soil environment. Our goal was to determine what amount of salt has some measurable negative effect on enzymatic activity of soils, namely on native proteases. Inhibition of proteases was detected at as little as 0.5 mg of chloride salts in an organomineral horizon from an oak stand, but in most cases, some inhibitory effect appeared from 1-2 mg of salt added to the soil. Although the stimulatory effects of salt were also observed, in those cases it probably was not associated with activity of the microbial community. Our results indicate the levels from which the activity of microorganisms will probably decrease and organic matter decomposition will be slowed.

“…Currently, more than one third of the world's arable land is subjected to soil quality, and land degradation due to salt stress and agricultural yield has greatly decreased (Fan et al, 2012;Gao et al, 2018;Li et al, 2014;Tilman, Balzer, Hill, & Befort, 2011). Additionally, the salt-affected area is increasing at a rate of 10% yearly because of high evaporation, low rainfall, inadequate irrigation, and other irrational anthropogenic activity (Himabindu et al, 2016;Liu et al, 2017;Mose et al, 2018).…”

“…By 2050, the salinized area will exceed 50% of global arable land (Liu et al, 2017;Mao, Kang, et al, 2016;Mao, Zhang, et al, 2016;Sun et al, 2018). So breeding salt-tolerant crops is vital to feed the increasing population (Yamaguchi & Blumwald, 2005).…”

Salt stress is a major problem happening in almost all the world, affecting soil metabolism and acting further negatively soil fertility and soil quality, causing land degradation and low ecosystem service functions and ecosystem productivity. In marshy area as one type of important marginal land resources, salt is also the main barrier to be improved and the driving force to make vegetation succeed. This commentary briefly reviews the main advance focusing on salt‐affected soil and introduced the publications in this Special Issue: Salt Soil Improvement and Efficient Development in Land Degradation & Development 29, 2018, to promote global cooperation for studying salt‐affecting soil quality, land degradation, and eco‐restoration.
