The dose order was: [t.sub.3] > [t.sub.4] > [t.sub.5] > [t.sub.1] > [t.sub.0] > [t.sub.6] > [t.sub.2]; [t.sub.2] > [t.sub.3] > [t.sub.4] > [t.sub.1] > [t.sub.5] > [t.sub.0] > [t.sub.6;] [t.sub.4] > [t.sub.3] > [t.sub.2] > [t.sub.5] > [t.sub.1] > [t.sub.6] > [t.sub.0] for carbamate-pesticides I, II, III respectively on micronutrient concentration in wheat grain and straw grown on aeric
This study suggests that although tillage and residue management will not influence the loss of nitrate, tillage will affect herbicide persistence in Aeric
Cryaquepts of Subarctic Alaska.
Three soils were collected from production fields by excavating the A horizon and were considered soils representative of the (1) Commerce series (Fine-silty, mixed, nonacid, active, thermic Aeric
Fluvaquents), (2) Sharkey series (Very-fine, montmorillonitic, nonacid, thermic Vertic Haplaquepts), and the (3) Crowley series (Fine, montmorillonitic, thermic Typic Albaqualfs).
1998), described the dominant soils as Blount (Aeric
Ochraqualfs, fine, illitic, mesic), Glynwood (Aquic Hapludalfs, fine, illitic, mesic) and Lenawee soils (Mollic Haplaquepts, fine, illitic, mesic).
The soils are fine, montmorillonitic, acid, thermic Aeric
Fluvaquents of the Estes Series (Natural Resources Conservation Service staff).
The soil type of experimental station was loamy clay (loamy mixed and thermic Aeric
They gave their names as Daniel Magtira, Aeric
Bernardino, Anicio Escosura, Mel Chavez and Melito Lagata.
The predominant soils in this sub-watershed include Blount silt loams (fine, illitic, mesic, Aeric
Epiaqualfs), Pewamo silty clays (fine, mixed, active, mesic Typic Argiaquolls), and Glynwood loams (fine, illitic, mesic Aquic Hapludalfs).
Soils are classified as Spodosols (sandy siliceous, hyperthermic Ultic Alaquods from the Pomona series or sandy siliceous, hyperthermic Aeric
Alaquods from the Smyrna series) with average pH of 5.9.
McClain (1985), who studied the soils in North Woods, described the dominant soils as Blount (Aeric
Ochraqualfs, fine, illitic, mesic), Glynwood (Aquic Hapludalfs, fine, illitic, mesic), and Lenawee Soils (Mollic Haplaquepts, fine, illitic, mesic).
