Nitrogen. This is essential for leaf growth, and is used in higher proportion where a large plant and lots of foliage are desirable. Certain plants extract nitrogen from the atmosphere. One example is the leguminous plants, which include peas and beans. They have nodules on their roots that actually absorb nitrogen directly from the environment, and require little additional chemical nitrogen in their fertilizer. Corn, grains, and other crops that have narrow leaves, on the other hand, often require more nitrogen to thrive. It is represented by the N in the standard fertilizer label. Phosphate. This is another chemical that plants require for good health. It is a product of phosphate mines or industrial waste, and plants use the chemical phosphorus in cellular processes. Phosphate is more common in soils containing a lot of clay, and is quickly leached from sandy loams or basic sandy soils. It is represented by the P in the standard fertilizer label. Potash. This is the third chemical in the fertilizer description. It is also used by the plant at a cellular level, and is necessary for good bloom production and healthy fruiting of the plant. It is represented by the K in the standard fertilizer label.

Secondary nutrients are needed in lower proportions than the basic three chemicals noted above, and help maintain the soil quality and contribute to healthy plants. The secondary nutrients include these: Calcium Sulfur Magnesium. Micro-nutrients. These are also essential for good plant health, and may or may not be included in your fertilizer choice. Look for the following, in particular: Iron, in soluble form, helps with blooms, and to keep foliage green Copper, in soluble form, also helps keep foliage green, and will improve resistance to some diseases Zinc Manganese. Decide if you want to combine other products with your fertilizer before purchasing. Special formulations of fertilizers that include herbicides and insecticides are available, and can be used to save application labor and time. Using these, however, limits you to areas where the chemical additives will not have an adverse effect. This includes fertilizers that contain pesticides that will contaminate plants, and herbicides that will damage the plants you are intending to grow. In general, using insecticides and herbicides on specific problems allows you to decrease the amount you need, and target problems with more effective results.

Pre-plant application on a small area can be done by scattering fertilizer over the entire area and the tilling it into the soil. Apply at a rate of one or two pounds for each 100 square feet (9. 29 square meters) maximum to avoid over-fertilizing the area. Broadcast pre-plant application is suitable for larger areas, and a typical rate of application would be 200-400 lbs/acre (pounds per acre), using a calibratable fertilizer spread either pushed by hand, or pulled by a lawn tractor or farm tractor. After application, till the soil to incorporate the fertilizer and decrease the chance of run-off if rain occurs. To avoid poisoning the plants, especially tender young ones, dilute the fertilizer into a bucket or watering can filled with water. Use that solution to water your plants. This method also helps the plant absorb it easier. After watering the plant with fertilizer, water it another time, this time with regular water. This second watering is done to remove fertilizers that may have dropped on leaves and stems. Unwanted fertilizers on leaves might cause damage and corrosion. Direct application to individual plants or plants in rows can be done by pouring the fertilizer into a clean, dry bucket, then walking down the row dropping the fertilizer next to plants. Avoid dropping the fertilizer directly on plants, as the chemicals can burn them. Use a small amount, around one tablespoon each for small plants. Direct application to row crops can be done with a cultivator equipped with a side-dressing apparatus. This apparatus consists of a hopper with a wheel to drive a dispensing mechanism and chutes to direct the fertilizer to the row.
Repeat the application of fertilizer as needed to maintain good plant growth/ crop production. Using smaller amounts of fertilizer at frequent intervals may be more beneficial than applying single applications at a high rate, as some of the fertilizer can be lost by leaching or in run-off if heavy rains occur after it is applied.
Store your fertilizer spreaders or other tools in a dry place when not in use, and make sure they are well lubricated and maintained.
