Of chemicals used in agricultural production (pharmaceuticals, fertilizers, etc.) negative effects on human and community health by increasing damage has begun to make itself felt. All these negative effects of the elimination of chemical fertilizers and agricultural purposes of war, no drug or as little as possible to use, they also served as a place of the organic fertilizers and biological warfare methods to take based on ecological agricultural system that has been developed. By FAO and the European Union as an alternative to conventional agriculture adopted by different names in different countries, this production method is an. Organic agriculture, ecological system, faulty applications as a result lost its natural balance again geared towards building human and environmentally friendly production systems, including on and the mainly synthetic chemical pesticides, hormones and mineral fertilizer use of the ban as well as organic and green fertilization, alternation, land preservation, plant Improving the resistance, to take advantage of natural enemies advised that not all of these facilities in a closed system recommended the creation, production increase not only the quantity but also in product quality which aims to increase production is a form of an alternative.
                Turkey and the countries with the same climatic zone the amount of organic matter in soil is very low level. As a consequence of soil nutrient holding capacity is also low. Increasing the amount of soil humus as the increase of soil productivity in a long time is extremely important in terms of soil productivity. Germany, Russia and England are still continuing the long-term experiment according to the results applied to the land of different fertilization programs as a result, alone or chemical fertilizer applied plots of land in the amount of humus in the beginning to the moment is a drop by when organic matter is added in the plots of these values increased slightly but organic matter in plots farther than the amount of humus and mineral fertilizer application rates, but no longer at the rate of increase in efficiency was provided to 114% are reported. In addition to soil organic matter experiment similar to the soil structure will gain a stable and high-nutrient environment in the soil surface is estimated to be less than the removal of this land that a strategy is extremely important in terms of continuity. Both developing and developed countries and in most soil fertility of the soil and improve production capacity by the continued use of natural resources are. Today many western countries, traditional agricultural techniques instead of the known mechanisms to protect nature and the alternative farming techniques are applied. In most countries, organic agriculture, developed under the name of the system as possible in the use of natural resources in agricultural production in the foreground is extracted. In the face of rapidly increasing world population and enough food to provide the necessary use of chemical inputs has entered into all areas of agricultural production. But in the recent past, especially the first and most widely used chemicals in the country has begun to put forward a new alternative approaches. Nutrition of plants, especially plants use natural mechanisms, as well as come to the fore is made of extra reinforcement. Western European countries today, 10% of the organic farming enterprises closer to the presence of words is known. These enterprises as possible, using organic resources, more healthy and quality products will be produced and are offered to consumers. Even a few times higher than in markets these products in the price buyers are found.
               Organic Production What is it? According to the natural organic produce organic production within the organization is located. Organic materials and products in agriculture within the agricultural system is used consistently. Organic agriculture means that products of synthetic fertilizer, herbicide, insecticide or without the use of Fungicidal is to educate. Alternative farming practices rather than intensive agriculture, soil health and reduces the need to protect and synthetic inputs. Crop production is mainly synthetic fertilizers and organic inputs were neglected as intensive use of pesticides applied to agricultural systems have been suffering. In the production of organic crops to diseases, insect pests and weeds of plants against their natural immune system to develop a rotation of crops and soil organic matter by providing the durability of the system is increased in the plants.
              Principles of Organic Agriculture
There are 3 main principles of ecological agriculture. Including:
1. Production compatible with nature
2. Closed System (Self-Sufficient Agriculture)
3. October Watch
              Under this principle, taking into account national and regional ecological conditions, agricultural activities can gain variations. However, in general, contain the following activities.
              Vegetable production;
Appropriate minimum tillage methods 
Protect and improve soil productivity  studies aimed
Use of organic fertilizers instead of chemical fertilizers 
 Durable, healthy selection of seeds and plant varieties
Planting-planting method appropriate 
Instead of direct chemical input use in protecting plants  ecological methods and input use
 harvest, storage, processing and packaging activities in the conduct of the ecological methods
              Animal production;
 A healthy animal husbandry
 Suitable stable conditions
 Utilization of organic food
Ecological fitness and race in the selection of breeding 
              All policies considered together, the ecological agriculture in a particular cultural environment, social, economic and ecological factors to ensure balanced development is observed. The system combines all the factors within the cultural structure of ecological agriculture is a philosophy.
Advantages and Disadvantages of Organic Agriculture
              Benefits
Synthetic chemicals in our country our farmers  A large part being used by either too little, or not used at all. Therefore be expected to be an easy transition to ecological agriculture.
Depending on the product revenue  Manufacturers are increasing (the estimated average increase of 10%.).
 Price rapidly increasing chemical fertilizer, pesticide and energy inputs are from the savings.
All of the manufacturer's product in agriculture  Contractual guarantees are to be taken.
Export prices of products from other products  Ecological ratio is higher than 10-20%.
Ecological Products with the export of our country  agricultural products is creating an additional capacity. Therefore, every ton exported consumer previously has gone to be reached.
The ecological agriculture model of Agriculture Special  request information for engineers, has created new employment areas.
Disadvantages
In our country, year after year in the supply of agricultural products  significant fluctuations are seen. Increasing rapidly and becoming young population, consumption level and the steady increase in diversity and the environment in almost all the countries of the demand for agricultural products due to the characteristics of organic farming (in yield may occur due to a decrease) in the short term seems to be difficult to develop.
Ecological agriculture in crop production with the method  a problem arise, land is too small, fragmented and is close to one another. This situation negatively affects the organic production. Because an ecological production business around the production of other chemicals used in conventional businesses can not be influenced
Agricultural products grown in the ecological system  marketing of new and uncertain, especially for the domestic market is an issue. .
Because of the subject sufficient agricultural extension  new studies and other negative aspects of ecological agriculture is the lack of staff.
                Organic Fertilization Method: the use of chemical fertilizers, organic manure is not to be the essence of. As usual, the land must be included in the amount of nutrients for the plant production system, the preferred opinion organic fertilizers that replaces chemical fertilizers and is not suitable in terms of health, as well as the high costs that have been reported. Oldest known agricultural use of animal manure applications. However, before using animal manure, compost to be processed in; kills harmful bacteria, removes unwanted odors and minimizes the loss of NO3. Other organic food sources, fish waste, natural phosphates (rock phosphate), bone meal, cotton seed and moss is. Rotated with other crops to grow the legume crops is very important in terms of fertilizer application. Leguminous plant roots as it is known in the rhizobial nodules are host bacteria. These bacteria through the air to form N of the plant will use the free form of converting the plant to ensure that. Clover, Lupine, legumes, such as in this way provide their own nitrogen requirements. Typically, large seedy grown for grain legumes that bacteria (such as beans) from the production of nitrogen, more nitrogen is used for seed production and generally in increasing or improving the soil nitrogen is used.
                 Legumes or oats, rye and wheat, non-legume plants such as leaves are used as a source of N in the soil and the green is called fertilization. The Austrian winter pea is a legume widely used.

                 Miscellaneous Organic Agriculture-Related Research

                 USA, the 1990's based on organic farming, plant breeding in 24% as demand increased. This demand at the beginning of the awareness of consumers, products and wastes on the pesticide chemical inputs such that began in the face (Govindasamy and Thompson). Nutrition, environmental health and sustainable agriculture in terms of alternative soil improvement was significant. But organic foods increases, the economic popülütesi began to increase in input (Govindasamy; Klonsky and Thompson). However, the demand for organic agriculture at a rate of 12-60% of the increase were followed (Lohr, 1998). This tendency to show more farmers to organic agriculture has provided (Langley, Klonsky and Thompson).
                 Breeding for organic farming, the re-entry with an organic soil type, soil structure as a benefit for the future is. This is enough water for plants at the beginning of the benefits of increased capacity, KDK, low volume density of the soil, and beneficial effects on the activity of microorganisms is (Doran and Drinkwater). Compost applications, soil improvement, soil stabilization, and high pH due to increased agregasyonlarýný infiltration rate increases (Stamatiadis et al., 1999). Chemical characters of soil, soil improvement and production systems are determined by. For example, in the long-term legume production Rodela institutes and organic production systems, soil organic matter and nitrate losses decreased the increment was observed (Drinkwater et al., 1998). Conventional (chemical inputs that) according to the agricultural systems, organic production systems than the small amount of soil loss and water loss was observed N (Liebhardt et al., 1989).
                  Traditional agriculture, the amount of N in the soil found in the soil microbial komponentleriyle negative relationship, while organic farming conditions in the positive relationship was found (Gunapala and Scow, 1998). At the same time yield obtained by the organic agricultural production and traditional agricultural production is equal to the amount obtained from the yield was observed. California in the vegetable garden from a survey of organic agriculture, traditional agricultural production to the amount received from the amount of yield was found to be equal (Drinkwater and Stamatiadis). Pennsylvania also another study done to confirm the previous research in parallel to each other similarities were found in the amount of yield (Drinkwater et al., 1998). Limited field work in the light, organic and conventional production systems on the microbial population is understood to be the influence of soil improvement (Drinkwater and Gunapala). However, microbial activity and biomasýn traditional agriculture, according to the regulations of organic agriculture is deemed to be higher (Drinkwater et al., 1995). Most of the applications made in research in the soil microbial population increases organic not stay, diversification of species and also provide micro-organisms has also increased activities. California in a study done on tomato growing a variety of activities Actinomycetes prevent root fungus disease has been observed that (Workneh).
                   Organic agricultural practices of soil physical, chemical and biological characteristics of organized and not being able to separate soil and plant systems will allow forward progress. Another study of applications made organic synthetic applications, according Ca, K, Mg, Mn has provided the content in the soil increased (Bulluck et al., 2001). This is similar to work as farm fertilizer applications, plant C, P, K, Ca and Mg concentrations in the soil increased C, P and K contents were observed to be decreased (Clark et al., 1998). Alternative agricultural practices against synthetic applications, soil pH was initially measured as low, but later applications over time against the alternative synthetic applications at a level higher than the amount of pH was observed to watch. Organic practices in the future to increment the amount of organic substances, healing of physical and chemical properties of low dose applied with the fertilizer has provided. Another study, both organic and conventional farming systems of apple production that was seen in the equal, however, organic farming practices have been observed taken at higher quality apple fruit (Reganold et al., 2002). Which is useful as a soil fungus Trichoderma species organic and conventional (synthetic) in agricultural activity has been observed in different harvest time (Bulluck et al 2002). Both in the chart; organic (alternative) production of mushroom species found in the environment, conventional (synthetic) media production to the higher fungal colonies were formed.
                    Bulluck et al (2001) in his study of traditional agriculture based on organic farming inputs to the soil biology, chemistry and physical properties and has been observed that at the same time increase productivity.
                    Organic farming practices and the spread of human population growth ahead, with the expected demand in a balanced manner can not reply to all the ecological elements together with the financial input is necessary to consider. All of these factors compared to a trial by traditional agriculture and organic farming, the financial input is deemed to be higher. However, organic farming practices, traditional agricultural practices and integrated than the minimum N losses, pesticide risk, herbaceous plants, such as biological differences in terms of many environmental factors are understood to be more appropriate. (Pacini et al., 2002). The result of agricultural production, economic production and helps to find the balance between environmental objectives (Halberg, 1999). Hardaker (1997) sustainable agriculture and an appropriate balance between agricultural development strategy has emphasized the need to address.
                    Sustainable agriculture researchers have recognized the importance of agricultural production systems. Research in this direction and to work towards understanding the requirements were bent. Sustainable agriculture with the natural life in a negative effect has been to prevent the harmful. As is known, improvements in the organic soil physical, biological, chemical properties of improving the quality of the products was also increased. However, the financial input of organic farming with the traditional agriculture needs to be kept in a balance of input. Over the next century would be nutrition Sellin, we further spread of organic farming in the future, and by people who claim to be more to say at all would not be wrong. However, the future of organic farming by people indispensable to arrive at a level more research is needed.
