Macronutrients are nutrients needed by plants in relatively large amounts compared to other nutrients. Examples of Macro Nutrients are Nitrogen (N >1%) , Phosphorus (P = 1,21 %) , Potassium (K > 13%), Calcium (Ca >14%), Magnesium (Mg >1 %), and Sulfur (S). 1. Has Micro Nutrients (Mn, Zn, Cu, B and Co.)

which function as a constituent of plant tissue. As a catalyst (stimulant). Affects the process of oxidation and reduction of plants

Having Organic C content is an important factor determining the quality of mineral soil. The higher the total organic C content (30,3%), the better the quality of the mineral soil. The higher the organic matter content, the higher the amount of nitrogen it contains, so that plant growth will be better. In soil ecosystems, C- organic is an important component that influences soil properties to support plant growth, namely as a source of energy for soil organisms and a trigger for nutrient availability for plants.

Having C/N which is one of the most important aspects of nutrient balance. The C/N ratio of organic matter is the ratio between the amount of carbon element content and the amount of nitrogen content in a material.
