“…Therefore, APRD improved the IWUE by 35.6% without any significant yield reduction (Tables 1, 3). This result is in agreement with the advantages of APRD on saving irrigation water reported in several previous studies (Topak et al, 2016;Sezen et al, 2019;Shu et al, 2020). In addition to the improved IUWE, N absorption was also enhanced under APRD (Table 3).…”

“…Higher leaf ABA concentrations were observed throughout the growing season under APRI compared with that under other treatments (Kirda et al, 2004). The enhanced remobilization of photosynthates and higher harvest index induced by APRD were also observed in our previous studies (Zhang et al, 2014;Shu et al, 2020).…”

“…It belongs to a typical temperate humid climate, with an average annual relative humidity of 71%, an annual average frost-free period of 202 days, and sunshine hours of 2315.8 h. The experiment was initiated on February 28 and finished on June 25, 2017. The experimental soil was sandy loam (Shu et al, 2020). The pH of the soil was 7.3, with 26.2% (gravimetric) or 0.341 cm −3 field water capacity, 1.6 g kg −1 total N, 37.4 mg kg −1 nitrate N, 0.6 g kg −1 total phosphorus (P), and 1.3 g cm −3 soil bulk density.…”

The efficient utilization of irrigation water and nitrogen is of great importance for sustainable agricultural production. Alternate partial root-zone drip irrigation (APRD) is an innovative water-saving drip irrigation technology. However, the coupling effects of water and nitrogen (N) supply under APRD on crop growth, water and N use efficiency, as well as the utilization and fate of residual nitrates accumulated in the soil profile are not clear. A simulated soil column experiment where 30–40 cm soil layer was 15NO3-labeled as residual nitrate was conducted to investigate the coupling effects of different water [sufficient irrigation (W1), two-thirds of the W1(W2)] and N [high level (N1), 50% of N1 (N2)] supplies under different irrigation modes [conventional irrigation (C), APRD (A)] on tomato growth, irrigation water (IWUE) and N use efficiencies (NUE), and the fate of residual N. The results showed that, compared with CW1N1, AW1N1 promoted root growth and nitrogen absorption, and increased tomato yield, while the N absorption and yield did not vary significantly in AW2N1. The N absorption in AW2N2 decreased by 16.1%, while the tomato yield decreased by only 8.8% compared with CW1N1. The highest IWUE appeared in AW2N1, whereas the highest NUE was observed in AW2N2, with no significant difference in NUE between AW2N1 and CW1N1 at the same N supply level. The 15N accumulation peak layer was almost the same as the originally labeled layer under APRD, whereas it moved 10–20 cm downwards under CW1N1. The amount of 15N accumulated in the 0-40 cm layer increased with the decreasing irrigation water and nitrogen supply, with an increase of 82.9–141.1% in APRD compared with that in CW1N1. The utilization of the 15N labeled soil profile by the tomato plants increased by 9–20.5%, whereas the loss rate of 15N from the plant-soil column system decreased by 21.3–50.1% in APRD compared with the CW1N1 treatment. Thus, APRD has great potential in saving irrigation water, facilitating water use while reducing the loss of residual nitrate accumulated in the soil profile, but has no significant effect on the NUE absorbed.

“…Thus, there are many environmental factors interacting with each other and influencing the soil structure and, consequently, the plant development (Ozkazanc et al, 2019;Aricak et al, 2020;Ozel et al, 2021;Koc, 2021). The climatic factors such as precipitation, temperature, and light (Kilicoglu et al, 2020;, the edaphic factors such as soil pH, amount of organic matters, and depth (Kravkaz Kuscu et al, 2019;Varol et al, 2019), the factors causing stress such as drought (Topacoglu et al, 2016;Mahmood et al, 2020), frost (Sevik and Karaca, 2016;Joshi et al, 2020), pollution (Mutlu et al, 2016;Mutlu and Aydın Uncumusaoglu, 2016;Mutlu and Kurnaz, 2017;Mutlu and Aydın Uncumusaoglu, 2017;Aydın Uncumusaoglu and Mutlu, 2017;Mutlu and Kurnaz, 2018;Turkyilmaz et al, 2018;Kükrer and Mutlu, 2019;Mutlu, 2019;Ucun Ozel et al, 2020;Emin et al, 2020;Kutlu and Mutlu, 2021;Tokatli et al, 2021), and human-origin factors such as fertilization (Moncada et al, 2021;Soumare et al, 2021), irrigation (Shu et al, 2020;Parkash et al, 2021), and hormone implementations (Guney et al, 2016a,b;Yucedag et al, 2019;Ashokhan et al, 2020) significantly affect each other, plant development, and soil structure. In conclusion, in order to determine the effects of enzyme activities on soil fertility and plant development and to use them purposefully, it is necessary to increase and diversify the future studies to be carried out on this subject.…”

Analysing the factors driving the population size and activities of soil microorganisms is important for understanding the soil ecosystem’s structure and functioning. For this purpose, the soil enzymes are used as an indicator of soil microbial activity and soil fertility. Although there are many studies on the distribution and activities of various soil enzymes in soils under monoculture or crop alternation conditions, there are only few studies examining the ecological relationship in natural ecosystems, especially by using enzymes. In this study, it was aimed to determine the effect of different land uses on the catalase enzyme activity in soil. For this purpose, the catalase enzyme activities in soil samples taken from 0-5cm and 5-10cm depths in agricultural, forest, and pasture lands in north and south exposures were determined and the effects of different land use, exposure, and soil depth conditions on the enzyme activities were investigated. At the end of the study, it was determined that the catalase enzyme activity significantly differed by the land use and the highest level of catalase enzyme activity in both south and north exposures and at both depth levels was found in forest soils, whereas the lowest level of activity was found in agricultural lands in north exposure and pasture soils in south exposure.

“…In the face of these shortcomings, the traditional solution is to increase the amount of irrigation and fertilizer. However, a large number of studies have shown that, for many plants, there is a threshold for both irrigation and fertilization, and a blind increase in irrigation and fertilization does not significantly increase crop yield [7][8][9].…”

Water storage pit irrigation (WSPI) has been proven effective in improving the water use efficiency of fruit trees in Loess Plateau, but so far there are still no matching efficient fertilization management methods. A two-year experiment was conducted to explore the management strategy of fertilization under the consideration of apple production and environmental sustainability. N isotope tracer technique was used to study the distribution of labelled nitrogen in soil, leaf, root and fruit. Moreover, the yield in different fertilizer managements were observed to evaluate the apple production. The results showed that increasing the amount of fertilizer could increase the accumulation of fertilizer nitrogen in soil, but also increased the risk of nitrogen leaching. Under the same amount of fertilizer, split fertilization can effectively increase of fertilizer nitrogen in soil by a mean of 4.7 times. Further, N300 application with split fertilization effectively increased apple yield. The yield of N300II treatment was higher than other treatment by maximum 68.5%. In addition, the root system mainly absorbed the fertilizer nitrogen applied in the current year, and the fruit mainly absorbed the fertilizer nitrogen applied in the previous year, but there was no significant difference in the leaves.
