A macronutrient bulletin for the prairies

Abstract

This paper briefly highlights some of the contents of a recently completed bulletin, which provides an up-to-date record of the status of our knowledge with regards to crop responses to, and impact on the environment of N, P, K and s, on the Canadian prairies. This 12 Chapter, 527 page book presents information on nutrient balances, trends in fertility levels of soils, nitrogen use efficiency, N, P, K and S cycles, fertilizer N practices, the influence of nutrients on soil organic matter, response of. forages to nutrients, biotechnology and crop nutrition, and the impact of nutrients on the environment. This manuscript, which was prepared through funding provided under the Canada-Saskatchewan Environmental Sustainability Initiative (ESI), should be of considerable assistance to students, educators, scientists and agricultural extensionists in the three prairie provinces.
