Abstract
Description
次に、平均粒子径1μm〜2mmのアクリルアミド単重合体5.0gにイオン交換水200ミリリットルを吸水させて形成された塊状物を、直径45mmの容器に厚さ6mmとなるように収容し、直径40mmの圧縮板により1Nの荷重を印加する操作を1時間に亘って3600サイクル繰り返し、圧縮時に発生した最大荷重を測定した。結果を実施例として図1に示す。
次に、300ミリリットルビーカーに、平均粒子径1μm〜2mmのアクリルアミド単重合体6.0g、精製水240ミリリットルを添加し、24時間静置して形成された塊状物に市販の家庭園芸用複合肥料(株式会社ハイポネックスジャパン製、製品名:ハイポネックス液6−10−6、水溶性肥効成分として、アンモニア性窒素2.90質量%、リン酸10.0質量%、カリウム5.0質量%を含む)60gを添加した。前記ビーカーを上部を開放した状態で、23±1℃、50±5%RHの室内に静置し、質量減を測定することにより、次式から保水率を求めた。
保水率の経時変化を実施例として図2に示す。
次に、平均粒子径1μm〜2mmのアクリルアミド単重合体5.0gに精製水500ミリリットルを吸水させて形成された塊状物に、肥料(水溶性肥効成分として、アンモニア性窒素3.12質量%、リン酸11.7質量%、カリウムを3.84質量%、マグネシウム0.04質量%を含む)を0.125g添加して、緩効性肥料組成物を調製した。
各水溶性肥効成分の質量は、アンモニア性窒素及びリン酸についてはIC(イオンクロマトグラフ)法により求め、カリウム及びマグネシウムについてはICP−AES(誘導結合プラズマ発光分析計)により求めた。結果を表1に示す。
各水溶性肥効成分の質量は、24時間静置後に分離された水分の場合と全く同一にして求めた。結果を表1に示す。
次に、福島県いわき市付近の土壌(以下、「いわき市土壌」と略記する)に対し、平均粒子径1μm〜2mmのアクリルアミド単重合体のみからなる保水材を0.3質量%添加して、本実験例の土壌を調製した。次に、本実験例の土壌を用いて植物を栽培した場合と、前記いわき市土壌に前記保水材を添加せずにそのまま用いて植物を栽培した場合との比較を図3及び図4に示す。
Claims (4)
- 1μm〜2mmの範囲の平均粒子径を有するアクリルアミド単重合体のみからなる保水材と、該保水材に保持可能な水溶性肥効成分とを含むことを特徴とする緩効性肥料組成物。
