The entrance of nutrients and sediments to the water resources has become a challenge in water quality management. Accordingly, identifying main polluting sources and estimating total loads discharged to the surface waters are indispensable for simulation and management. The purpose of this study is to use Soil and Water Assessment Tool (SWAT) to estimate nitrogen and phosphor loads discharging to the Zrebar Lake. In addition, it is intended to identify the effects of land uses and variations of time and spatial pattern of discharges. Currently, this lake contains fresh water and is used for recreational purposes while tackles with eutrophication problem because of agricultural activities. Regarding the results, the irrigated farmlands have the highest nitrogen discharge on June and August while it is on May for phosphorous. For dry crops, the highest value of nitrogen and phosphorous loads respectively belong to October and September. These are attributed to the way farms are irrigated and the amounts of fertilizers applied. Manuscript profile

Images of God are the result of the efforts of the human mind to understand better the mysterious and sacred existence.One of the most prominent images of God in the infinite range of human imagination is the "God of the Farmer" from whom we can call God's action in agriculture. This image, inside of the images of the realm of herbages makes the aspect of God's action in creation objective and tangible.God's activity in agriculture in texts that contain images for God, despite its dynamic presence, has undergone several changes. The present article has been reviewed this image in mythology, sacred texts and mysticism with a descriptive-analytical method and with the approach of metaphorical analysis. In mythology, the creation of God in the work of the goddess of fertility and the god of plant death is explained in the form of the rotation of seasons. In the sacred texts, this action is assigned to Ahuramazda, Yahweh, the God of the Father and Allah, in accordance with the context of each text, and in mysticism, this action is depicted in a diverse and comprehensive way with human focus.The results of the study showed; this image has passed a rotational journey from nature outside to nature within man and from objective nature to nature. In addition, the expansion of God's authority and dominion over the world and man is one of the things that can be seen in the transformation of this image. Manuscript profile

Internet of Things (IoT) as an emerging technology in the field of Information and Communication Technology is the next revolution related to the Internet application. IoT focuses on the communication of things such as sensors, drivers, devices, etc., with data collection capability controlling remote communication rather than focusing on the communication between people. Development of smart solutions and new technologies of IoT in agriculture can pave the way to a new paradigm of farming called “Smart Agriculture” by making a fundamental change in all aspects of current practices. IoT-based Smart Agriculture can improve agricultural productivity with more food production through the optimal utilization of the basic resources, minimizing environmental impacts, reducing the costs, and increasing the incomes with linking to the business market that facilitates sustainable agricultural development goals. IoT-based data is a collection of large data called “Big Data” that cannot be processed and managed by traditional databases and conventional management tools. IoT and Big Data technologies are interconnected and it can be predicted that the future of optimal agriculture in the world would not be possible to meet the food demand and sustainability of production without these technologies and Smart Agriculture. This article introduces IoT and Big Data technologies, as well as the relationship between them from the vision of Smart Agriculture. Moreover, the article aims to assist in the decision-making of the strategy from the pre-production stage to the business marketing in the country by assessing life cycle and technology trends. Some of the big IoT data applications in the Smart Agriculture cycle are also introduced. Manuscript profile

In societies like ours, before oil revenues came to power, the national economy was based on agriculture and was the only source of treasury and government spending. In the present era, despite the reduction of the role of this sector in the economy, the study of the function of economic sectors in the framework of national macroeconomics still confirms the significant role of the agricultural sector in the country. Agriculture is the main pillar of livelihood and economy of the people of Gilan. But the issue that has received less attention is regional justice and balance in having agricultural facilities and services among the cities of Gilan province. In fact, the evidence suggests that some cities are at a higher level in terms of development, and in this regard, there is an imbalance between cities. The research method is descriptive-analytical. Gilan Agricultural Statistics (2014) was used for data collection. Shannon and TOPSIS entropy models were also used for data analysis. The results of TOPSIS model in the group of indicators "Agricultural Tools and Technologies" showed that Rasht counties , Someh Sara, Lahijan and Tavalesh are in the first level of development: Astaneh-ye Ashrafiyeh, Rudsar, Bandar Anzali, Shaft and Fuman counties in the second level and Langarud, Amlash, Siahkal, Rudbar, Rezvanshahr and Masal and Astara counties in the third level Are located.

New technologies can transform the agricultural industry as well as any other industry. The final goal of the research is to identify and stratify the factors affecting the development of emerging technologies in agriculture with a supply chain approach. The research method is mixed and initially, the components of emerging technologies in agriculture are identified through literature and semi-structured interviews with experts. Interviews were coded with three methods of open, central and selective coding, and finally 34 components and 182 indicators were identified based on central coding and in the quantitative part a structural-interpretive model to present the model of emerging technologies in agriculture using ISM according to the opinions of 15 people. It was created by the experts of Tarbiat Modares University. After that, to identify the position of the identified components, it was determined using MICMAC based on influence and dependence. The obtained results of emerging technologies in agriculture are formed in six levels including the central category, contextual factors, causal conditions, intervening conditions, strategies and finally, consequences. The findings of the research show that by using interpretive structural modeling, the location of various factors in the dispersion map of the variables was analyzed, from which the position of the key variables can be recognized. From the state of the scatter plot of variables affecting new technologies in agriculture, it has been observed that the system is unstable Manuscript profile

Water is one of the problems of today's world and it is necessary to conserve it. Many parts of the world are facing drought conditions. The purpose of this research is to analyze new and different techniques in modern agriculture. In this regard, it has been tried to introduce new methods using super absorbents. With the advancement of science and technology, excellent polymer materials have been developed to retain water. In this article, water retention agents based on natural and synthetic polymers have been reviewed in the last 10 years. Finally, the synthesis of two types of natural and synthetic super absorbents using recycled materials is described. Hydroxyethyl cellulose has excellent characteristics of a superabsorbent such as being biodegradable, non-toxic, high water absorption, and is one of the derivatives of cellulose, which is used in water extraction, wastewater treatment, electrolytic membranes, pharmaceuticals, and pesticides. Alternative soil has many applications in agriculture. And its use can be expanded by combining with different polymers. This combination allows the formation of new biomaterials with improved properties and various applications. As a result of preparing a water retention agent with a practical perspective in agriculture, it not only enhances water absorption and water retention in the soil, but also is resistant to salinity and has mechanical strength, re usability and economic value. is. All these features are present in the introduced super absorbents. Manuscript profile

During the last century, science and technology have grown and developed significantly, however, this development, along with all the advantages and added values for the quality of human life, has brought inappropriate effects on the environment. Unfortunately, the human conflict with the problems which has created for the planet, including wars and new diseases, has caused less attention to the impact of climate change on environment and especially the related agriculture activities. If the agricultural sector exposed by climate change and will not be able to meet human food needs, life will be near to its end point. Agricultural activities are not only exposed to these changes, but also by leaving possible negative effects on environment lead to these changes. Threatening food security, the reduction of biological diversity, the loss of soil, the reduction of water resources, and the conversion of forests into farms and their gradual destruction, turn the earth into an unlivable area with the unpredictable occurrence of storms, floods and temperature changes. Therefore, investigating the impact of climate change and its components on different ecosystems and species that affect agriculture can be a step towards achieving new management mechanisms to reduce and adapt to these changes and achieving sustainable environment and agriculture.
