 note = {本県の土壌診断で主に用いられている全農型土壌分析器ZA-2の沖縄本島南部地域土壌(島尻マージ，ジャーガル)における分析値への適用性を検討した．その結果，可給態リン酸含量は両土壌型ともZA-2分析値で100mg/100g以下で高い相関関係が認められた．交換性石灰は両土嬢型ともZA-2分析値で1200mg/100g以下で高い正の相関関係が認められた．そして，ZA-2分析値は従来法の分析値に比べて比較的に高い値を示す傾向があることも明らかとなった．交換性加里は両土壌型ともZA-2分析値で60mg/100g以下で高い正の相関関係が認められた．そして，ZA-2分析値は従来法の分析値に比べて低い値を示す傾向があることも明らかとなった.交換性苦土は両土壌型とも今回検討した測定範囲においては，従来法の分析値と高い正の相関関係が認められた．陽イオン交換容量は島尻マージにおいてはZA-2分析値で13～25me/100gの範囲で高い正の相関関係が認められたが，ジャーガルでは有意な相関関係は認められなかった．腐植含量は両土壌型ともZA-2分析値で4%以下で高い正の相関関係が認められた．そして，ZA-2分析値は従来法に比べて低い値を示す傾向があることも明らかとなった．, It was studied on the application and coverage of Zen-Noh type soil analyzer ZA-2 to Shimajiri Mahji and Jahgaru soils in the southern part of Okinawa island. The results were as follows. The values under 100mg/100g of available phosphate in soils using ZA-2 showed a high positive correlation with there by Truog method on the both soils. Each coverage values of the exchangeable calcium(Ex-Ca) under 1200mg/100g, potassium(Ex-K) under 60mg/100g and magnesium(Ex-Mg) at present content in soils using ZA-2 showed a high positive correlation with there by Peech method on both soils. Using ZA-2 method, the values of Ex-Ca showed a rising tendency but Ex-K a lowering tendency compared to the same method, respectively. Under 4 % of humus content on both soils using ZA-2 indicated a high positive correlation with there by Tyurin method but the values showed a lowering tendency compared to the same method. The values of cation exchange capacity from 13 to 25me/100g in soils using ZA-2 showed a positive correlation with there by Peech method on Shimajiri Mahji soils however it was no significant correlation in Jahgaru soils., 論文},
