Agricultural manure not only ensures that plants grow well, but also ensures their nutritional composition. One of the most common types of agricultural fertilizer is nitrogen fertilizer, which comes from animal and plant byproducts. This type of fertilizer is most often spread on top of the soil in which plants are growing. Phosphorus fertilizers are another common type of fertilizer, and usually come in a fine powder. Farmers who grow potatoes and fruit trees often use potassium fertilizers to make sure that their produce has enough of this nutrient.
Nitrogen fertilizer, which is made from the byproducts of animals and plants, is one of the most common types of agricultural fertilizer. Often, manure, fish meal, or other animal byproducts are spread on top of growing surfaces, releasing nutrients into the earth and feeding the newly-planted products. Though nitrogen fertilizers are often used, they can be somewhat difficult to work with, as applying too much of the fertilizer can "burn" plants. New users of this product may want to consult with a botanist to learn how to properly apply nitrogen-based fertilizer.
Examples of agricultural fertilizers also include those with high concentrations of phosphorus. Typically, this phosphorus comes from steamed bone meal that has been pulverized or is in powdered form. Phosphorous-enriched fertilizers can often be obtained in a variety of concentration levels. As with nitrogen-based fertilizers, it is important that farmers research which concentration of phosphorus is best for the plants they are growing. In many cases, the quality of the soil can also greatly determine which phosphorus fertilizer will be used.
Growers of potatoes, fruit trees, and some other potassium-rich produce will often need an agricultural fertilizer that contains high amounts of this nutrient. For best results, planters should test their soil to determine how much potassium agricultural fertilizer is needed. Soils that are very sandy typically need the most potassium, while clay soils may need less. Kits that test potassium concentration can usually be purchased at hardware or home improvement stores. Those who do not feel comfortable performing these tests on their own can often receive assistant through their local agricultural counsel.
Farmers who are planning to purchase agricultural fertilizer may want to do some research on the company they are planning to buy from before committing to a large purchase. Understanding the exact nutritional composition of the fertilizer, the manner in which it is created, and the price associated with fertilizers are all important considerations. Farmers should be prepared to spend a significant amount of time researching the companies they are interested in buying from.
