Diskli Gübre Dağıtma Makinaları İçin Değişken Oranlı Gübre Kontrol Sistemi

Aim of this research is to develop a variable rate controller system includes mechanical part, electronic circuit,application map software and laboratory test system apply variable rate fertilizer application due to requirement of cropinstead of constant rate of application used by farmers generally. Centrifugal fertilizer spreader with two discs, steppermotors, variable rate controller, GPS and variable rate application software were used as materials in this research.Developed variable rate controller and application software were improved. In addition, a laboratory test software wasdeveloped. Laboratory tests of the new control system were realised. 15-15-15 (N-P-K), %46 Urea, 20-20-0 (N-P-K)and %33 Ammonium Nitrate chemical fertilisers widely used by farmers for field crops were used in the laboratory tests.Developed system was worked without any problem.Bu araştırmanın amacı; çiftçinin uyguladığı alışılagelmiş homojen gübre uygulama yerine bitkinin ihtiyacına uygun belirlenmiş miktarları konuma göre dağıtan gübreleme yapan daha önce geliştirilmiş bir makine ile değişken düzeyli gübreleme yapmaktır. Araştırmada materyal olarak santrifüjlü gübre dağıtma makinesi, step motor, değişken düzeyli kontrol sistemi, GPS ve uygulama haritası programı kullanılmıştır. Araştırmada daha önce geliştirilen kontrol sistemi ve değişken düzeyli uygulama programı iyileştirilmiştir. Ayrıca laboratuar testleri için bilgisayar programı geliştirilmiştir. Yeni sistemin laboratuar denemeleri yapılmıştır. Testlerde çiftçiler tarafından ülkemizde tarla tarımında yaygın olarak kullanılan 15-15-15 (N-P-K), %46 Üre, 20-20-0 (N-P-K) ve %33 Amonyum Nitrat gübreleri için testler yapılmıştır. Sistem testler sırasında sorunsuz olarak çalışmıştır

Araştırmada farklı skala değerleri için gübre normu (kg/da) olarak saptanmıştır. Sistem testler sırasında sorunsuz olarak çalışmıştır. Proje ile ilgili araştırmalar değişik senaryolar için sistemin çalışmasının kontrol edilmesi için devam ettirilecektir. Sistemin tarla testleri TAGEM tarafından yürütülen Ulusal Hassas Tarım Projesi çerçevesinde Kırklareli Atatürk Araştırma Enstitüsünde yürütülecektir.Aim of this research project is to apply variable rate fertiliser application due to requirement of crop instead of constant rate of application used by farmers.

Fertiliser rate as kg/da were determined. Developed system was worked without problem. Future work of this project will be carried out for determining system performance for different variable rate scenarios on the concrete surface. Field test of the system will be carried out in Ataturk Soil, Water and Meteorological Research Institute under National Precision Farming Project

DEVELOPMENT OF A PRECISION FARMING SYSTEM FOR TURKISH FARMERS

International Conference on Agricultural Engineering: New Technologies for Sustainable Agricultural Production and Food Security -- FEB 24-26, 2013 -- Muscat, OMANThe objective of this paper is to explain the information about a precision farming system which has been developed for Turkish farmers. The developed system includes a variable rate controller for centrifugal fertiliser spreaders, an application map software and an autonomous steering system for tractors. The variable rate controller for the centrifugal fertiliser includes stepper motors used to adjust the distributed fertiliser amount. An electronic control system was designed to control stepper motors in addition to a DGPS system, which was used to determine positioning. The application map software was used to provide communication between the variable rate system and the stepper motor, computer and DGPS. In order to develop a variable rate controller, a toothed axle was fitted to the stepper motor. A variable rate controller was developed to combine cereal sowing machines. This system includes step motors for each seed metering unit as well as PIC, PDA and GPS receivers. The software was developed to create an application map and send signals to control units. Furthermore, an automated steering system was developed by a private Turkish company. Preliminary test results of this system were successful. The system is still being tested.Int Soc Horticultural Sc
