1. Independence of Crop Yield and Nitrogen Rate Across Sites Historically soil fertility specialists in the North Central States of the USA have constructed nitrogen (N) rate recommendations based on ‘yield goals’ or ‘expected yield’. Within the past ten years, there has been a general realization by soil fertility researchers that within a site or field there is a relationship between N rate and yield; however, because of soil and weather differences between sites there is no relationship in N rate studies with a large number of...

2. Micronutrients in Northern Climates Early work on micronutrients in northern US dates back to the late thirties and early forties and dealt primarily with boron (B) (Cook 1939; Cook a nd Millar 1940; Pierre and Allaway 1941). In Manitoba, it was initiated in the sixties and id entified zinc (Zn), copper (Cu) and manganese (Mn) as potential problem micronutrients. Early work also id entified organic (peat) soils as a primary target for micronutrient deficiencies. Work on mineral soils would produce significant yield responses in the... Download paper
