The frequency of soil diagnosis was not enough except for some prefectures, or some tree species. The formulation of the reduction standard for fertilizer application has not progressed in many prefectures, so joint studies or test data sharing thought to be important to accelerate the formulation of the reduction standard. Compost utilization was well done in gently sloping orchard, but fertilizer application taking into account the amount of nutrient in the compost were not practical enough. The controlled release fertilizers, drip irrigation and liquid fertilization were expected to reduce the amount of fertilizer, and these extension is underway. Using of fertilizers containing low amount of phosphorus and potassium, and Bulk-Blending fertilizer were also progressing. Using of less frequently used low-cost materials, such as potassium chloride or chicken manure, were also promoted partly now. In the future, these fertilizer application improvement in Japanese orchard could be enhanced by sharing more test data and information in participants.}, pages = {65--83}, title = {果樹園における施肥改善等に関するアンケート調査報告}, volume = {12}, year = {2011}, yomi = {クサバ, シンノスケ and イノウエ, ヒロミチ} }
