- Abstract
This study aimed to evaluate the formation of wet bulbs in sandy and clayey cultivated soil. The evaluations were made in two Coffea Canephora cultivated areas, the soil texture being sandy to loam (area 01) or sandy clay (area 02) typical of coastal zones. For the wet bulb characterization, to measure soil moisture, several cylindrical access-tubes were mounted for use in time-domain reflectometry. The tubes were arranged at six points in relation to the plant, being one point on the planting line between two plants and five points on the planting line (0.10; 0.40; 0.70; 1.10 e 1.50 m of the plant), the measurements conducted in four depths ranges (0.00-0.20; 0.20-0.40; 0.40-0.60 e 0.60-0.80 m) with three replicates. The wet bulb presented vertical formation in the area with sandy to loam texture and reached a depth between 0.40 and 0.50 m, with a range of up to 0.10 m between coffee lines. The wet bulb formation occurred in the horizontal direction in the area with sandy clay texture, reaching depth values of 0.20 to 0.30 m, with a range of 0.10 to 0.15 m between lines.
