翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Lawn aerator ： ウィキペディア英語版 Lawn aerator A lawn aerator is a garden tool or machine designed to create holes in the soil in which lawn grasses grow. In compacted lawns, aeration improves soil drainage and encourages worms, microfauna and microflora which require oxygen. ==Lawn problems== Lawn aeration constitutes two things: controlling lawn thatch and reducing soil compaction. Lawn thatch is a layer of dead organic tissue that can protect the lawn by moderating temperature and reducing evapotranspiration when it is a reasonable thickness, but too much thatch can limit soil oxygenation and reduce watering effectiveness.. Soil compaction makes it difficult for grass to develop long roots and disturbs both natural rainwater and artificial irrigation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lawn aerator」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
