 Abstract
Nitrogen content in soil is a major factor for the crop growth. Ammonium nitrogen in soils is volatilized when soil pH is high. The growth and development problem of strawberry such as color of leaves turning into purple was found when soils were treated with the compost prepared from suspended solids of high pH from the sea. From in-situ analysis it was found that soil pH was 8.33 and nitrate, phosphorous, and potassium contents were relatively low. Nitric acid was added to adjust pH of irrigating water as 1.7, 1.9, and 2.3, then and were added. It was resulted that soils with pH 1.7 produced the most developed strawberries. Strawberry was recovered by irrigation containing the same solution. From the results, the growth and development problem of the strawberry resulted from low nitrate absorption rate. It was concluded that the growth and development of strawberries were recovered by the reduced soil pH using nitric acid.
