Question

Background Soil samples were obtained from two horizons for each of three profiles. The Marlow series consists of well drained soils formed in compact, loamy glacial till on drumlins and glaciated uplands derived mainly from mica schist, granite, and phyllite. The Telos series consists of somewhat poorly drained soils on till plains, hills and ridges formed in dense glacial till derived mainly from slate and other dark colored sedimentary and metamorphic rock. The Buxton series consists of very deep, moderately well drained soils that formed in glaciolacustrine ne deposits on coastal lowlands and river valleys. These soils are moderately fine, and fine textured. White pine(Pinus strobus), balsam fir (Abies balsamea), and red spruce (Pice rubens) seeds, germinated in an incubator, were planted in pots containing soil collected from surface and subsurface horizons of Marlow, Telos and Buxton soils. Seedlings were grown in the greenhouse for six months at the University of Maine. Results of the experiment are given in Table 11.1. With these data, answer Questions 1 to 3.

Explanation / Answer

Solution:-

Question no-1

In Telos series, both horizons O as well as B are producing tallest seedlings for the three tree species in compare with other.

Question no-2

Telos series contains the good amount of organic matter in hills and ridges. Its soil water holding capacity is less than other series and fertility of soil is more as it contains good amout of nitrogen.
