“…It is evident from the results that the application of fertilizer with IN resulted in the highest utilization of nitrogen by wheat compared to the same total dose of nitrogen applied in classic nitrogen technology with three split nitrogen fertilization. A similar finding is also presented by Dawar et al [ 91 ], where the utilization of IN in combination with Urea also increased the ANE, or by Shalmani et al [ 89 ], where the application of IN with ammonium sulphate increased the ANE even in the drought stress conditions. A possible explanation can be also in the forms of nitrogen applied in each treatment.…”

“…As it is evident from the results, such a combination resulted in a higher yield of winter wheat grain, the highest weight of AGB and the highest residual N after the harvest. The positive effect of IN application on the winter wheat yield is also described by several authors [ [89] , [90] , [91] , [92] , [93] ]. These increases in grain yield after IN application highlight the fact that application of the IN, which increases the proportion of mineral N in the NH 4 + form, provided an equal opportunity to take up applied N as NH 4 + form.…”

Soil fertility and nutrient management are the main factors that directly affect the yield of the product. To evaluate the soil fertility at different elevations (including 1600-2000, 2000-2400, 2400-2800, and >2800 m), 350 surface soil samples (0-30 cm) were collected from the agricultural lands of northwestern Iran.Then, soil properties, including soil texture (%), CaCO 3 (%), pH, EC (dS.m -1 ), organic matter (OM) (%), and soil nutrients (macro and micro) (mg.kg -1 ), were measured. Finally, the interpretation and classi cation of the soil samples were made using the nutritional value index (NIV) based on the Gomez and Common methods. The comparison of the NIV index based on elevation changes showed that the Gomez method tends to classify the soil properties in the optimal class due to its tendency towards the center of the data. But the Common method is more consistent with reality. After classifying the NIV index using the Common method, it was determined that CaCO 3 (%) and soil salinity is not the main problem for soil fertility in different elevation classes. However, in all elevations, high pH, low OM (%) at elevations >2800 m, total nitrogen (TN) (mg.kg -1 ), available phosphorous (AP) (mg.kg -1 ), and micronutrients de ciencies (except Zn at the elevation of 1600-2000 m) are the main limiting factors for soil fertility of agricultural lands. Therefore, to improve the soil fertility in all the elevations of the agricultural lands in the northwest of Iran, there is a need to improve the condition of macro and micronutrients (mg.kg -1 ), especially TN (mg.kg -1 ). Highlights 1. The NIV is a suitable and practical index for evaluating soil fertility.2. At all elevations, TN and pH were the factors of limited soil fertility.3. The EC and CaCO 3 do not limit soil fertility at any elevation.
