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
The three main ingredients in sugar soap are sodium carbonate, sodium phosphate and sodium silicate. There is actually no sugar in the list of ingredients for the soap.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 >
Fertilizer affects plant growth by supplementing plant nutrients, which allows plants to grow faster and thicker. However, this applies only if the soil is deficient in nutrients. Fertilizer does not compensate for other growth-inhibiting factors such as lack of water, poor soil preparation and weeds.Full Answer >
The best fertilizer for squash is a balanced 10-10-10 fertilizer. The nitrogen helps the plant grow, while the potassium and sodium improve fruit production. The fertilizer may be either granular or water soluble.Full Answer >
