Economics of controlling a spreading environmental weed [PDF]
Weeds can cause significant problems to natural ecosystems. Although there have been numerous studies on the economics of weed control, relatively few of these studies have focused on natural ecosystems. This paper addresses this gap in the literature by

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fractions and their distribution, molecular characterization, enzyme activity ...

THE VALUE OF INFORMATION IN HERBICIDE DECISION MAKING FOR WEED CONTROL IN AUSTRALIAN WHEAT CROPS [PDF]
Most weed control decisions are made with the benefit of some information about weather conditions and actual weed densities. This study is an investigation of the value of adjusting weed control decisions in response to these types of information. For a
