This study was conducted to determine the annual energy use and related greenhouse gas (GHG) emissions of individual deep well irrigation enterprise. That study was conducted at deep well farm belonging to one farmer with volunteer preforming farming activities in Konya-Meram-Çarıklar location for the growing season of 2021. In that regard, the activities using alfalfa and dry bean production, and total production inputs with their amounts as well as crop yields were determined separately. By considering unit energy equivalent values and GHG emission factors of each input, annual energy consumption and GHG emission values were calculated. Similarly, by examining energy content and crop yield in accordance of crop production unit (kg), annual produced energy amount was calculated. The evaluation was made using energy used and energy produced as well as GHG emission values indicators at individual deep well irrigation farm. According to the results obtained, annual energy use and energy production were calculated 253035 mega-joule (MJ), and 487960 MJ, respectively for individual well irrigation farm. The electricity used during the irrigation processes resulted around 71% of annual energy consumption. The annual GHG emission amount as an equivalent to the carbon dioxide (CO2eqv) for research farm with GWI was determined as 18575 kg (18575 kgCO2eqv year-1). Almost 52% of annual GHG emission was resulted from electricity used in irrigation.

Global warming, which has been increasing in recent years, is due to the increasing amount of greenhouse gases in the atmosphere. The agricultural sector, which has a 25% share in greenhouse gas formation, plays an important role in global warming. CO2, which has a share of 82% among greenhouse gases, is shown as the most important greenhouse gas. It is estimated that 10% of the CO2 in the atmosphere is missioned from the soil. When soil organic carbon, which is an indicator of soil fertility, is released into the atmosphere as CO2, N and S compound gases return to the earth and it causes inefficient soil as well as global warming. Organic carbon is a source of CO2 emissions when the soil is mismanaged. The organic carbon in the soil is transformed into CO2 with loosening of the soil and accumulates in the atmosphere, after it exposure to temperature and oxygen. Unconscious tillage and irrigations increase the physical and biological activity of the soil and cause CO2 emissions from the soil. CO2 emission, which is the main cause of drought, needs to be reduced with low cost, easy and practical applications. At the beginning of these applications, can be listed reduced tillage, deficit irrigation, reduction of fertilizer usage, reuse of agricultural wastes and agricultural management of wastewater. In this review, it is aimed to investigate CO2 emission effect of soil tillage depth and tools, exhaust gases of the vehicles used in soil tillage, the amount of irrigation water and irrigation methods, deficit irrigation, irrigation with wastewater, precipitation, plant factor, fertilization, properties and temperature of soil. In addition, approaches that can be applied to reduce CO2 emission are mentioned.

Agriculture must be necessary and sustainable for the continuity of human beings. For sustainable agriculture, productive crops can be made with good irrigation in productive crops and conscious irrigation in good irrigation. A survey was conducted with 111 producers in the central district of Tokat province to determine the factors affecting conscious irrigation and conscious irrigation. In the research, first of all, the socio-demographic structure of the producers was determined: it was determined that the producers with an active working population had a low level of education. In the second part of the research, irrigation information was tried to be determined and it was observed that most of the producers were doing salman irrigation. In the third part of the research, irrigation awareness was tried to be determined by using the scoring method of the producers and it was determined that 24% of the producers were in the category with a high level of awareness. In the last part, the factors affecting irrigation awareness were determined with the help of the ordered probit model. As a result, it has been determined that there is a linear relationship between the level of awareness of the producers, their educational status and membership in the irrigation union.

This study includes some deep underground well waters opened to supply the irrigation water in Tekirdağ province. The sampling was done from 22 wells in the irrigation season period. The parameters such as pH, EC, TDS, Na, Ca, Mg, K, Cl, HCO3, B, NO3-N, Sodium Absorption Ratio and Residual Sodium Carbonate parameters, which were significant in terms of irrigation water classification, were examined in the samplings. According to the results, it was determined that thirteen well waters were in medium salty and eight well waters were in high salty water classes. Besides, Na and HCO3 harms were determined in five and three well waters, respectively. In seven well waters, it was concluded that RCE values were over 2,5 me L-1 and these water were not suitable in the usage of irrigation. As a result of the evaluations in terms of the specific ions, it was determined that CL, B and NO3-N concentrations which were found in three, two and one wells respectively, could create damages in some crops. As a result of the evaluations in terms of salinity and SAR parameters, it was concluded that the usage of T5, T6, T8, T10, T13 and T14 well waters was undesirable and the usage of T9, T11, T12, T16, T17 and T21 well waters can be suggested by the provision of some special conditions (appropriate drainage conditions, appropriate plant selection, coarse textured soils).

Most of the non-irrigated areas in the southeast of the Harran Plain are irrigated by groundwater. The aim of this study is to determine the importance of 13 underground irrigation water sources operating in the agricultural areas of Ohali village in southeast of Harran Plain in Sanliurfa province in terms of some quality characteristics and irrigation. In this context, the waters belonging to 13 underground wells were analysed and examined in terms of irrigation water quality. According to the results of the analysis, the electrical conductivity of water samples was measured between 1127-4090 µS/cm. The SAR value of irrigation water was found to be between 1.05-3.41 and the %Na value was between 16.2% - 31.8%. In the evaluation made according to four different classification systems, in general, waters 6, 7, 8 and 9 were determined as the worst quality in all classification systems. These waters are described “unsuitable” irrigation water. Considering that the plants which have high water consumption such as cotton and corn are cultivated in the region, it is foreseen that if the necessary precautions are not taken, the salinity in the soil will increase and yield losses will be high. It is imperative that these areas, which cannot be irrigated within the scope of GAP irrigation project, be irrigated with clean water as soon as possible. However, an appropriate drainage system must be installed in the area.

Türkiye’nin toplam tarım arazisi varlığında yıllar itibariyle azalış meydana gelmesine rağmen ekonomik olarak sulanabilir nitelikte arazilerin üretime kazandırılması sayesinde mısır üretim faaliyetleri Türkiye’de yaygınlaşmıştır. Sulama imkânının olduğu alanlarda mısır; işçilik maliyetlerinin az olması, birim alanda yüksek verim avantajı sağlaması ve ürün pazarının kolaylıkla erişilebilir olması nedeniyle üretim açısından popüler bir üründür. Sulama alanlarının artışına paralel olarak üretimi yaygınlaşan mısır; ekonomik değeri yüksek fakat su tüketim miktarı da yüksek bir üründür. Bu yönüyle çalışmada işletmecilerin tarımsal faaliyetlerin sürdürülebilirliğine, mısırın ekiminden hasadına kadar geçen süreçte karşılaştıkları problemlerin çözümüne, üretim ile ilgili beklentilerine yönelik analizlerin yapılması amaçlanmıştır.
