内容 千葉大学森林環境園芸(利根高冷地)農場内の森林土壌および果樹園土壌(地点名は各TNF-3およびTNO-5)の無機成分および粘土鉱物組成を分析した結果, 以下のことが明らかとなった.1.両土壌ともに, 現在の表層と下層の土壌の下に過去の表層と下層の土壌が埋没し, それぞれA/Bw/2A/2Bw層およびAp/2BC/3BC/4Bw/5AB/6A層の配列であった.2.両土壌ともに可給態リン酸含量は表層(A, Ap層)が下層よりも高く, とくにTNO-5のAp層はTNF-3のA層より8倍程度も高かった.逆にリン酸吸収係数はA, Ap層が下層より低く, リン酸吸収係数とアロフェン推定含量とは高い正の相関関係が認められた.3.陽イオン交換容量はTNF-3ではA層のほうがBw, 2A, 2Bw層より高かったが, TNO-5ではAp層より5AB, 6A層のほうが高かった.交換性のカルシウム, マグネシウム, カリウム含量および塩基飽和度はTNF-3よりTNO-5が大きかった.4.両土壌ともに, A, Ap層は下層よりも粗砂の割合が大きく, 粘土, シルトおよび細砂の割合が小さかった.5.両土壌ともに, A, Ap層の酸化物(OX), 非晶質粘土鉱物(AC)および結晶性粘土鉱物(CC)の割合は概ね30, 40および30%であった.しかし, TNF-3の2A層, TNO-5の4Bw, 5ABおよび6A層ではOX, AC, CCの割合は約10, 30および60%で, A, Ap層よりOX, ACの割合が小さく, CCの割合が大きかった.6.両土壌ともに, 結晶性粘土鉱物組成はいずれの層もアルミニウム-バーミキュライト(Al-Vt)およびクロライト(Ch)を主体とし, これにアルミニウム-スメクタイト(Al-Sm), スメクタイト(Sm)およびバーミキュライト(Vt)が含まれる組成であった.
We investigated the composition of clay minerals and a few inorganic elements of the soils in the apple garden (TNF-3 : A, Bw, 2A and 2Bw) and Japanese eeder (Cryptomeria japonica) forest (TNO-5 : Ap, 4Bw, SAB and 6A) in Chiba University's Environmental Horticulture and Forestry (Tone Ko-reichi) Farm. And we also clarified the following items. 1. Past surface soils and subsoils were buried under the present surface soils (A and Ap horizon) and subsoils (Bw horizon) in both TNF-3 and TNO-5. The arrangement of soil horizons were A, Bw, 2Aand 2Bw horizons in TNF-3 and Ap, 2BC, 3BC, 4Bw, SAB and 6A horizons in TNO5. 2. Contents of Available phosphorus (Av-P) of present surface horizons (A, Ap) were higher than those of subsoils and buried horizons in both TNF-3 and TNO-5. Especially, that of Ap horizon in TNO-5 was 8 times as high as A horizon in TNF-3. On the contrary, phosphate adsorption coefficients (PAC) of A and Ap horizons were lower than those of subsoils in both TNF-3 and TNO-5 and there was the high and positive correlation between PAC and estimated contents of allophone. 3. Though cation exchange capacity (CEC) of A horizon was higher than those in Bw, 2A and 2Bw horizons in TNF-3, those of 5AB and 6A horizons were higher than Ap horizon in TNO-5. Exchangeable calcium, magnesium, potassium and base saturation ratios (BS) of each horizon in TNO-5 were higher than those in TNF-3. 4. Proportion of coarse sand of A (or Ap) horizon was higher and those of clay, silt and fine sand of A (or Ap) horizon horizons were lower than those in the subsoils in both TNF-3 and TNO-5. 5. The proportion of oxides, amorphous clay minerals and crystalline clay minerals of clay fraction of A and Ap horizon were about 30, 40 and 30% respectively in both TNF-3 and TNO-5. Those of 2A horizon in TNF-3, 4Bw, SAB and 6A horizons in TNO-5 were about 10, 30 and 60%.0 There were less oxides and amorphous clay minerals and more crystalline clay minerals in 2A horizon in TNF-3 and in 4Bw, 5AB and 6A horizons of TNO-5. 6.
