How do I decrypt the fertilizer numbers?
The
fertilizers are mainly composed of three macronutrients with other micronutrients and minerals. Fertilizers concern the percentage of macronutrients, by weight, in the bag. Three numbers indicate the nitrogen content (n), phosphorus (P) and potassium (K). The mixture marked 20-15-10 would contain 20% nitrogen, 15% phosphorus and 10% potassium in this order. Fertilizers provide the manufacturer to help with the correct selection of fertilizers. The N-P-K designation is required by law and the content is guaranteed that it is the correct nutrient ratio. If the ratio contains the fourth number, the manufacturer included additional nutrients such as sulfur, iron or zinc. The rest of the weight is in the form of a filler that can make small nutrients and minerals. The purpose of the filler is to allow more uniform nutrient application without excessive overlap. Excessive nutrient concentration could damage the plants. Fertilizer 5-5-5 will usually provide nutrients almost all plants need healthy growth.
numbers of fertilizers are provided, abY has ensured that you use the right type of fertilizer for your soil conditions. The type of plants and soil requirements will determine the selection of N-P-K analysis. The soil test reveals the nutrients needed for healthy plant growth. The land testing sets are available in local home or gardens stores and from a number of online retailers.
The number of organic fertilizers should be interpreted differently. Organic fertilizers release nutrients slower. The N-P-K ratio must express the nutrients that are immediately available. The ratio of organic fertilizers is usually lower than the synthetic fertilizer. Fertilizers that contain organic and synthetic components must be marked.
complete fertilizers contain a percentage of all three nutrients such as 5-10-20. Incomplete or specialized fertilizers lack one or more macronutrients such as 0-20-20, which lacks nitrogen. Other ingredients are usually listed on the side label and may include micronutrients, minerals and organic matter. Fertilizers with higher numbers are usually more expensive,Because they contain more nutrients.
