NPK compound fertilizer
as a widely accepted and applied compound fertilizer, integrates the main three elements of nitrogen, phosphorus and potassium, providing essential nutrients for plant growth and development, while containing trace elements, reasonable and appropriate use of compound fertilizer, can significantly improve plant disease resistance and yield.
1.Nitrogen
It is the basis for proteins in plants and animals, and is present in the chloroplasts, which are the molecules within plants that perform photosynthesis, making food for the plants.
2.Phosphorus
Phosphorus is often referred to as "The Energizer" for its role in converting the sun's energy into food, fuel and fiber.
3.Potassium
Potassium is one of the three primary crop nutrients required for plant growth. Potassium serves as the "Regulator" of many essential processes within the plant.
The best NPK for vegetables
A balanced fertilizer with an NPK ratio of 10-10-10 or 5-10-5 is a safe bet for most vegetables. Keep in mind that different vegetables have different needs, and their growth stage also plays a role.
For example, tomatoes love a bit more potassium and phosphorus, so a ratio of 6-12-12 is perfect for them.
Cucumbers and peppers, on the other hand, are pretty well-rounded and like a ratio of 5-10-10.
Lettuce is a bit more low-key and only needs a ratio of 5-5-5.
Carrots, however, need more potassium and phosphorus for root development, so a ratio of 3-10-10 is ideal for them.
The best NPK ratio for growing flowers will vary depending on the specific flower you're growing and its growth stage. But in general, a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20 works well for most flowers.
Because lawns are all about lush green growth, they need a lot of nitrogen so it's best to use a fertilizer with a higher first number in the formulation. A fertilizer with an NPK ratio of 3-1-2 or 4-1-2 is great for most lawns.
A fertilizer with an NPK ratio of 2-1-1 or 3-1-1 works for most trees and shrubs.
The "3″ in the ratio represents the amount of nitrogen, which promotes leaf growth, and the "1" represents the amount of phosphorus and potassium which are essential for root development and overall health.
A balanced fertilizer with an NPK ratio of 15-30-15 or 20-20-20 is great for most houseplants.
Foliage plants like Alocasias and Aglaonemas need more nitrogen, while flowering plants like Cyclamen and African violets need more phosphorus.
By understanding the specific needs of the plants you're growing and choosing the right NPK ratio, you'll be giving your plants the best chance of thriving.
Don't be afraid to experiment and see what works best for your plants. If the choices are too overwhelming, stick with the simplest solution: pick a fertilizer that's optimally blended for specific types of plants.
