Effects of controlled weed densities and soil types on soil nitrate accumulation, spruce growth, and weed growth

Soil nitrate (NO 3 −) accumulation rates were assessed among seven weed species grown in small plots during the summer of 1997, at a northern Ontario location. Objectives were (1) to quantify soil nitrate accumulation rates at varying weed densities established on three soil types (clay, loam, and s...
