Ⅳ. 연구개발결과
완성된 초종의 건물수량 예측식은 지역별 기상 및 토양자료가 반영되어 농가에서 일반적인 재배기술을 이용할 경우 년간 건물수량 예측 가능하며 수요자에서 제공되는 SW (핸드폰 앱)는 기본적인 지역정보가 제공되고 있어 일반적인 수준의 수량예측이 가능하다. 과제에서 구축된 동계·하계 사료작물, 기상 및 토양 정보는 30년간 사료작물 보고서 생산량 데이터 베이스와 기상정보 및 토양정보의 이용 노하우로 정리가 가능할 것으로 사료된다.

The purpose of this research is to improve the precision of soil and climate factors across Korea for establishing the forage crops production prediction models, thereafter, to make a forage production-digital map software program considering the soil and climatic elements for the farmers or users to get an easy access to various information by mobile devices.

The research data for the past 30 years (1978~2009) on forage production of Korea is organized by forage species, production factors (forage yield, seeding date, harvesting date, fertilizer and forage cropping system etc.) by regional areas. The standard for the production factor has been made combined with soil and climatic elements on the organized data. The soil data was made using the soil map from Korea Soil Information System in RDA and climate data was based on the climate map from National Center for AgroMeteorology in Korea.

The regression model has been formulated by analyzing the correlation between the climate and soil map and necessary elements for forage crop suitability. After programming the results on the computer, the multiple information is being provided on forage production including the relevant soil and climate characteristics on the specifically chosen location and selected elements for forage crop production such as species, forage cropping system, seeding date, harvesting date and forage yield based on the location. Based on the data base and forage crops production prediction models, a forage production-digital map software program for the farmers or users to get an easy access to various forage crops plantation information by mobile devices was prepared.
