Effect of soil compaction and organic residues on spring-summer soil moisture and temperature regimes in the Sierra National Forest, California

Creator:

Troncoso, Guillermo E.

Abstract:

Soil moisture and temperature regimes during spring-summer 1996 were evaluated in plots with compaction and organic residues treatments established in 1993 at three sites in the Sierra National Forest after forest harvesting. The results indicate that the bare condition (non-compacted soil with total removal of the harvesting residues and forest...

Soil temperature suppression on growth and yield of potato (Solanum tuberosum L.) in warm climates of Sri Lanka

Creator:

Tharmarajah, S. K.

Abstract:

Potato (Solanum tuberosum L.) is one of the most productive and nutritious food crops. Due to its adaptability to cool climates, production in Sri Lanka has been restricted to erosion-prone highlands. Vast potential exists for expansion of potato cultivation in the lowlands while production areas in the highlands are limited...

The effect of preplant nitrogen fertilization and soil temperature on biological nitrogen fixation and yield of alfalfa (Medicago sativa L.)

Creator:

Shuler, Philip E.

Abstract:

The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa...
