“…Consequently, the K ‐factor decreases resulting in an increase in the T ‐value. The correlation between OM and MWD indicates that the existence of high OM content increases the size and stability of soil aggregates, which is in accordance with the findings by Santos, Reis, Martins, Castanheira, and Serralheiro (), and Vaezi et al (), Ostovari et al (2016), and Gavili et al ().…”

“…As shown in Table 2, the T-value has the highest correlation with OM, because OM that has an extensive specific surface area and high cation exchange capacity can play a key role as a binding agent among soil particles to create large and stable aggregates (Gavili, Moosavi, & Moradi Choghamarani, 2018;Nikseresht, Honarbakhsh, Ostovari, & Afzali, 2019). Consequently, the K-factor decreases resulting in an increase in the T-value.…”

Predicting soil loss tolerance (T‐value) as a first and crucial step in assessing soil erosion using pedotransfer functions (PTFs) could save time and cost. Therefore, this study aimed to evaluate T‐value and its influential parameters for calcareous soils of the Dorudzan Watershed, Fars Province, Iran, and to develop PTFs for its prediction using easily measureable soil properties. T‐value was determined in 60 soil profiles based on the soil thickness method. Various basic soil properties were used to develop five PTFs using stepwise multiple linear regression. T‐value varied from 3.5 to 22.5 with a mean value of 10.4 t ha−1 yr−1, which is approximately equal to the proposed value by US Department of Agriculture (11 t ha−1 yr−1). T‐value in Inceptisols located in the dam shore and agricultural lands was significantly higher than that of Entisols located in the forest and rangelands. Organic matter (OM) with a correlation coefficient of .77 with T‐value was the most influential variable in prediction of T‐value. The PTF 5, which used OM, soil aggregate stability, and permeability, with the highest R2 (0.72 and 0.79), the lowest mean error (−0.44 and 1.75 t ha−1 yr−1), the lowest root mean square error (2.98 and 2.75 t ha−1 yr−1) and the minimum Akaike information criterion (51.1 and 17.2) provided the best predictions for T‐value. However, when considering the acceptable indices and easier measureable soil properties (OM, soil erodibility, and pH) in PTF 3, we concluded that it was the best model to predict T‐value. Generally, the application of thickness method is recommended to determine T‐value in semiarid regions.

“…In this context, it is clearly understood from the study results that water can be saved considerably by irrigating at the I40 irrigation level of the spinach grown in the greenhouses in the autumn-winter period and dry regions with insufficient water resources. Similar results were also reported by Nishihara et al (2001), Leskovar and Piccinni (2005), Ors and Suarez (2017) and Gavili et al (2018) in spinach.…”

Drought is an abiotic stress factor that negatively affects plant development and causes economic losses in plant production, and its effect is getting more and more every day. Spinach contains a high amount of water and the drought stress affects its development, as well as causing changes in its biochemicals contents. In this study, it is aimed to determine the changes in the morphological, physiological and biochemical contents of spinach grown under deficit irrigation conditions in different stages of developmental. For this purpose, by considering five different irrigation levels (I100, I80, I60, I40, and I20), and 4 harvest times determined according to the development periods of spinach, a total of 20 experiment units were designed with 3 replications in completely randomized experimental design. Growth parameters were negatively affected by severe deficit irrigations such as I20 and I40. While the deficit irrigation caused a decrease in the relative water content (RWC), protein, and chlorophylls a and b, its increased membrane damage and carotenoid content. Besides, deficit irrigations have shown significant increases in proline, hydrogen peroxide, malondialdehyde, superoxide dismutase, catalase and peroxidase. When different irrigation levels and different harvest periods were evaluated together, water use efficiency (WUE) values ranged between 2.31 and 5.02 g / l, and the highest WUE value was obtained at the I40 irrigation level and Harvest-2 III. As a result of the Principal Component Analysis conducted to evaluate all the data obtained from the trial subjects together, the most important parameters explaining the effect of harvest time and deficit irrigation together were underground fresh weight, number of leaves, hydrogen peroxide and peroxidase. Consequently, considering the growth parameters, the I100 irrigation level without deficit irrigation and the I80 irrigation level with mild water stress were resulted in considerable outputs, especially in the Harvest III and IV.

“…Animal manures are regarded as a main source of organic matters (Burton & Turner, ; Gavili, Moosavi, & Moradi, ), which is one of the best organic fertilizers available, and an extremely valuable resource. The main sources of manures are pig, duck, sheep, chicken, and cattle farms.…”

Salt-affected soils are an important resources; although the crop yields in the soils are lower, they should not be ignored nor given up. By using pot experiments, five different organic amendments (pig manure, cattle dung, chicken manure, rapeseed meal, and biochar) were used to investigate their effects on the chemical properties and enzyme activities of coastal saline soil as well as the growth of wheat. We also compared the suitable application doses of these organic amendments. After the treatment of five organic amendments, soils were incubated for 30 days at a constant temperature and moisture. The results showed that organic amendments had the property to decrease soil pH, increase organic matter, change soil enzyme activities, and promote wheat growth. With the rapeseed meal addition at the dose of 50 g kg −1 , soil pH decreased from 8.29 to 7.06, which was 14.8% lower than that in the control soil (no amendments), the organic matter as well as the activities of catalase, urease, alkaline phosphatase, and saccharase significantly increased, and the biomass of wheat increased by 48.4%. Compared with control, the rapeseed meal and pig manure were recommended as the suitable soil amendments for remediating coastal saline soil, and the suitable application dose is 50 g kg −1 . These data suggested that rapeseed meal and pig manure are an efficient choice in improving salt-induced land degradation. This study will not only lay the theoretical foundation for remediating coastal saline soil but also provide advice on selecting organic matters in ameliorating coastal saline soil.
