Have you ever baked a cake? If you want the cake to turn out well you need to have the right amounts and ratios of ingredients. What would happen if you decided to modify the cake recipe and double the liquids, while cutting the flour and dry ingredients in half? It would mix just fine in a bowl, but when you take it out of the oven you would have some glop that nobody wants to eat, and you wouldn’t dare call it a cake. You must understand the right proportions to make modifications, or else you need to follow a recipe.
In this same way, you need to maintain the right levels and ratios of available nutrients in soil if you want to produce nutrient-dense foods. It is especially important to keep your eye on the big three: calcium, phosphorus and potassium. If you get these three right in your soil, everything else is a piece of cake.
