With all my talk about nitrogen lately I thought it would be cool to compare how different methods of nitrogen fertilization would look. As nitrogen is one of the few things that if we add more the plant will use more the differences in application rates can have a varied affect on plant health and response. The following chart illustrates the same amount of nitrogen applied per season but at different rates at different times of the growing season. Now we know that the blue line is what the plant actually needs so if the lines from the other application methods are above the blue line you are essentially over applying nitrogen and if the lines are below the blue line you are under applying. Over applying and under applying both have their purpose in turfgrass management but they also carry consequences. I read somewhere that a visual turf response can be seen at nitrogen rates as high as 6Kg N/100m2 per season! Currently my rates are about 1.4Kg N/100m2 per season. So essentially I ca
