Metrics are standards or ways to measure or evaluate something. Metrics are used in a variety of fields, for instance, they are used in the field of graph drawing to help position aesthetically pleasing graphs. There is much potential for using metrics in data visualization. This potential not only can help to layout and position the visual depictions better but also assets visualizations creation which is quicker to understand or calculate values that determine the similarity and differences of two visualizations. However, little research has been performed to investigate and clarify where and how metrics can be used in visualization. In this work, the usages of metrics visualization were investigated through a series of casestudies.

Plant nutrition is one of the determinate factors in fruit production cycles. Foliar fertilizer application is considered a complimentary nutrition method which proofed to be highly efficient under certain conditions. In this research, a foliar application of balanced foliar fertilizer N.P.K (20:20:20) +TE with different concentrations (0, 5, 10, and 15 g/l) was conducted on Coscia pear seedlings. Plant vegetative growth traits in addition to certain biochemical characteristics (Roots and leaves dry weight percentages, chlorophyll content, carbohydrates content, and minerals content) were measured. The results showed that plant height, stem diameter, branches length, leaf area, main roots number, root length, root dry weight, leaves dry weight, chlorophyll, and minerals content were significantly increased by increasing foliar spray concentration from 5 to15 g/l which confirms the importance of foliar spray as an enhancer of plant physiological operations. However, the highest carbohydrate content and carbohydrate/nitrogen (C/N) ratio were observed under A10 (10 g/l) treatment which might refer to the importance of this level of foliar fertilization, specifically in this phase, to accelerate the transition from juvenility to production phase.

Soil organic matter (SOM) is a key factor in maintaining soil quality. The main aim of this research was to investigate the distribution of soil organic matter in the coastal region of Syria. For this purpose, thirty-one representative soil profiles were prepared in Latakia governorate from three different land types according to usage (i.e. forest land, rangeland, and agricultural land). Soil samples were collected from the top layer, then analyzed. Results showed that the total organic matter (TOM%), as well as soil properties, varied between the studied agroecosystems. Notably, the average recorded TOM percentages were 5.34%, 4.38%, and 4.07% in forest land, rangeland, and agricultural land respectively. Additionally, matrix correlation between different soil aspects indicated a positive significant (p <0.05) correlation between clay content and Cation-exchange capacity (CEC), and between CEC and TOM in forest land cover. On the other hand, agricultural land showed a positive significant (p <0.05) correlation between water content and each of CEC and clay content, and between clay content and CEC.

Pre-harvest nutritional condition is one of the major fruit quality influencers in apple whether directly after harvest or throughout cold storage. Here, the influences of various levels of ammonium to nitrate on vitamin C content, total phenolic compounds, and total antioxidant capacity of three apple cultivars (‘Granny Smith’, ‘Gala’, and ‘Golab Kohans’) throughout cold storage period were studied. Five different ammonium nitrogen levels (0, 0.08, 0.16, 0.19, and 0.27 meq/L) were applied. After harvest, the fruits were transferred to cold storage and stored at 0±1˚C for 45, 90, and 160 days for ‘Golab Kohans’, ‘Gala’, and ‘Granny Smith’, respectively. Vitamin C content, total phenolic compounds, and total antioxidant capacity were determined throughout the storage period. The results showed that all cultivars showed different responses toward ammonium nitrogen application in terms of vitamin C content. ‘Golab Kohans’ recorded an increase in vitamin C content by increasing ammonium in nutrition solutions. On the other hand, minor changes were recorded in ‘Granny Smith’ and ‘Gala’. Total phenolic compounds and total antioxidant capacity were significantly increased under all tested levels of ammonium in comparison to control in all cultivars. Furthermore, all cultivars showed a significant decrease in vitamin C, total phenolic compounds, and total antioxidant capacity throughout cold storage, indicating that these bioactive compounds were subjected to decomposition and metabolic degradation during the storage period. Surface response analysis results showed that more vitamin C degradation was attributed to the increase in ammonium application, while less total phenolic compounds degradation and total antioxidant capacity decrease were observed under similar treatments.

The excessive use of fertilizers has become a necessity to support agricultural production in vast areas in Iraq. Phosphate fertilizers are known to contain relatively high concentrations of uranium‐238 (238U), radium‐226 (226Ra), thorium‐232 (232Th), and potassium‐40 (40K) radionuclides which accumulate in soil with time. In the current study, gamma-ray spectrometry was used to measure the radioactivity concentration of naturally occurring radionuclide in fertilized and non-fertilized soil samples within Latifiyah region in Iraq. The results showed that the average concentrations of 226Ra, 232Th, and 40K in fertilized soil were 12.7, 10.6, and 334 Bqkg-1 respectively which was 30.6%, 29.4%, and 12.9% higher than its concentration in non-fertilized soils with 8.81 7.48 and 291 Bqkg-1. Additionally, the average values of radium equivalent activity (Raeq), absorbed dose rates 𝐷 (nGyh−1), annual effective dose (indoors and outdoors), external hazard index (Hex), and Excess Lifetime Cancer Risk (ELCR) for fertilized and non-fertilized soils samples were evaluated. The results showed that the studied indices were 53.6 Bqkg−1, 26.4 nGyh−1, (0.129 and 0.032 mSvy−1), 0.145 Bqkg-1, 0.106 respectively in fertilized soils compared to 41.9 Bqkg−1, 20.7 nGyh−1, (0.102 and 0.025 mSvy−1), 0.113 Bqkg-1, 0.084 in non-fertilized samples. The Mann-Whitney U test showed a significant difference (p <0.05) between the studied fertilized and non-fertilized soils in terms of radioactivity concentrations in addition to all the investigated radiation hazard indices. However, the mean values of radioactivity concentrations and radiological hazard indices for study soils were well below the internationally recognized and therefore, fertilizer rates did not pose any radiological risk.
