Nitrogen Basics – The Nitrogen Cycle
Crop Uptake is the prime goal of N management on farms. The greatest efficiency occurs when adequate N is applied at a time when the crop is actively taking it up. Efficient N use also depends on a number of other factors including temperature, soil moisture, pest pressure, and soil compaction. In the moist Northeast climate, nitrate remaining

When plants are young and small, nutrient need is low. As plants enlarge and start to grow rapidly, nutrient needs increase dramatically. Competency Area 2: Basic Concepts of Soil Fertility 7.

Soil Texture - Cornell University
nmsp.cals.cornell.eduTexture should not be confused with structure, which refers to how soil particles are aggregated together. It is possible to improve soil structure via best management practices such as reduced tillage. However, it is very impractical (expensive) and thus ill-advised to modify a soil’s texture.
