Your lawn and garden need a variety of nutrients to grow and stay healthy. Soil is an important source of key nutrients such as nitrogen (N), phosphorus (P), and potassium (K), but it does not always contain sufficient amounts. This is why many homeowners rely on commercial fertilizers as supplements. There are many types of fertilizers and nutrients, each of which affects your plants and environment in a unique way. As a NPK Fertilizer Wholesaler, share with you.

Understand the NPK value

Fertilizers provide plants with three main nutrients: nitrogen, phosphorus and potassium. This nutritional ternary is so important to the health of plants that all fertilizers show NPK values on their packaging. The NPK value represents the volume percentage of nitrogen (N), phosphorus (P) and potassium (K) in the fertilizer. For example, a fertilizer with an NPK value of 16-16-16 contains 16% nitrogen, 16% phosphorus, and 16% potassium (the rest of the fertilizer contains fillers). This also means that the fertilizer NPK ratio is 1:1:1; that is, it contains equal amounts of the three main nutrients. Similarly, fertilizer types with an NPK value of 24-8-16 contain 24% nitrogen, 8% phosphorus, and 16% potassium—an NPK ratio of 3:1:2. Before choosing a fertilizer, use a soil nutrition test kit to determine the existing nitrogen, phosphorus, and potassium content to determine the best NPK ratio for the soil.

Types of fertilizer

Considering the NPK ratio suitable for your soil, you will look for this set of numbers in one of the two main fertilizers on the market: organic fertilizers and synthetic fertilizers.

organic fertilizer

The remains of plants, animals or minerals packaged and sold in their original state or in granular form are called organic fertilizers. These environmentally friendly fertilizers usually contain naturally occurring nutrients, so compared with synthetic fertilizers, the concentration of individual nutrients is lower. For this reason, home gardeners may pick them to help prevent fertilizer from accumulating in the soil and burning (ie killing) plants or polluting local water sources through runoff.

Synthetic fertilizer

Synthetic fertilizers are formulated from chemically treated compounds, such as ammonium nitrate or urea. These fertilizers provide a strong main source of nutrients, but do not bring any microorganisms to the soil, so the soil structure and water retention capacity remain unchanged. Compared with organic fertilizers, synthetic fertilizers are more affordable and can improve plants faster. However, the flip side of this fast action is that they do not provide nutrients to the soil for a long time-only two to eight weeks, depending on the fertilizer-and organic fertilizers provide nutrients for as long as the microorganisms need to decompose them. Although these types of fertilizers need to be applied more frequently, over-application can cause the fertilizer to burn, runoff into local water sources, and even destroy existing microorganisms in the soil.
