We endeavor to fully understand soil nutrition and how it feeds the crop. Once the soil is understood, we can think about how to best accommodate the crop’s needs. From the soil, crops need consistent nutrients, water and oxygen. Nutrients vary depending on what materials the soil is formed on, fertility additions and tillage practices. We have seen large differences in nutrients depending on different depths of soil. This is called nutrient stratification. When roots are fed in a layer lower in the soil during a dry period, and this layer is lower in certain nutrients, we can see deficiency symptoms appear. Double or triple depth sampling is the best way to understand where the shortcomings of nutrients may appear. We can then develop strategies to ensure your plants are receiving optimal nutrition, whether the conditions are wet or dry.
