Description

In January 2004, Alberta Environment contracted Timberline Forest Inventory Consultants to conduct data analysis and basic data interpretation of a dataset containing soil chemical analysis data. These data have been collected at regular intervals at eight sites (six coniferous forest sites and two grassland sites, mostly on coarse-textured soils) across the province since 1981 in support of the Long Term Soil Acidity Monitoring program. The main body of this report outlines the steps that were taken with respect to data preparation, software and procedures used, and assumptions made in handling the data. This report also makes comments on possible data limitations and provides some recommendations related to improving ongoing sampling and analysis.

Description

Lime is applied to acid soils to neutralize excess acidity that causes reduced crop yields. The application of lime does not improve saline or solonetzic soil conditions. There are over 1 million acres of strongly acid and 4.5 million acres of moderately acid soils farmed in Alberta. While many factors, such as the kind of crop, soil type, and climate, influence responses to lime, it can be generally stated that the application of lime should be considered on all strongly acid soils and on many moderately acid soils to improve and maintain productivity. Where liming is an established practice, it is applied to maintain soils in the most suitable pH range for the crops and soils in the area.
