The three main ingredients or macronutrients in fertilizer are nitrogen, phosphorous and potassium. Nitrogen promotes new growth of the green parts of flowers, such as leaves. It is also essential in the process of photosynthesis.Know More
The main nitrogen-based fertilizer is ammonia. Other nitrogen fertilizers include ammonium nitrate and calcium ammonium nitrate.
Phosphorous helps plants develop strong root systems and enhances flowering and fruiting. Phosphorous plays an important role in energy metabolism, respiration, photosynthesis, enzyme regulation and nitrogen fixation.
Potassium, commonly referred to as potash, is needed for the reproduction and optimal development of plants. It improves drought resistance and activates enzymes in plants. It also plays an important role in photosynthesis and protein and starch synthesis. Potash fertilizers include potassium nitrate, potassium sulfate and potassium chloride.
Fertilizers also contain three secondary macronutrients: calcium, magnesium and sulfur. These nutrients are needed for optimum plant growth. They help plants produce improved quantities of fruit, flowers or foliage.
Fertilizers also contain micronutrients or trace elements, which are already found in all soil types. These nutrients are needed in small quantities and can be obtained by recycling organic matter, such as tree leaves. They include iron, zinc, boron, manganese, copper, silicon, vanadium and cobalt.Learn more about Gardening & Landscapes
Corn gluten fertilizer is a natural by-product used in the creation of corn starches and is used as an alternative to chemical fertilizers. It is nontoxic and is primarily a source of nitrogen.Full Answer >
You should only apply potash fertilizer to soils that are lacking in potassium. You can determine soil potassium levels using a home soil test kit available from many local gardening stores. Potassium levels between zero and 60 require 3 pounds of potash for every 1,000 square feet.Full Answer >
The amount of fertilizer needed per acre is dependent upon many factors, including the type of plant being fertilized. In addition, the amount of nitrogen in the ground must be considered before applying fertilizer.Full Answer >
NPK stands for nitrogen, phosphorous and potassium, the three vital nutrients every plant needs. An NPK fertilizer provides those three nutrients in ratios particular to the plant being grown. A 5-10-5 fertilizer contains corresponding amounts of nitrogen, phosphorous and potassium.Full Answer >
