Juci Corn Factory will introduce you to nitrogen fertilizer:
Nitrogen is an important phytonutrient contained in many fertilizers, although the content is different. Chemical fertilizer manufacturers indicate the proportion of nitrogen in the product on the packaging label, but for organic fertilizers, the merchant will not clearly indicate.
What is nitrogen?
Plants use nitrogen to create their structures and perform a series of functions. This chemical element is present in plant tissues, fruits, seeds and grains, and forms part of chlorophyll, which turns plants green and causes them to process light into sugar. Nitrogen is also present in plant roots, which helps plants absorb moisture and nutrients in the soil. In addition, nitrogen is part of compounds that regulate plant development and growth. The nitrogen absorbed by plants from the soil exists in the form of a compound called nitrate.
Nitrogen in fertilizer
The three numbers shown on the chemical fertilizer product label tell the purchaser what percentage of each of the three essential plant nutrients the product contains. The first number represents the percentage of nitrogen; the second number refers to the content of phosphorus; the third number represents the percentage of potassium. If the number shown on the label on a 100-pound fertilizer bag is 30-10-20, the bag contains 30 pounds of nitrogen, 10 pounds of phosphorus, and 20 pounds of potassium. In order to grow and develop, plants need phosphorus, potassium and nitrogen. Artificial fertilizers that provide nutrients for all three major plants are called complete fertilizers.
Types of nitrogen fertilizer
Nitrogen is a nutrient necessary for plant growth, and it is possible to purchase fertilizers containing only nitrogen as the active ingredient. Fertilizers that supply the most nitrogen include urea (46-0-0) and ammonium sulfate (21-0-0). Due to the high content of urea nitrogen, if it is applied alone, it will damage the plants, so it is usually sold in combination with other agents.
Conventional wide-range landscape fertilizers usually contain the three main plant nutrients in a 2-1-1 or 3-1-1 ratio, while garden and lawn fertilizers have a higher proportion of 12-6-6 or 10 -8-6. Many chemical fertilizers quickly release nitrogen and other nutrients into the soil. However, slow-release and controlled-release products that can release nutrients over a period of time can also be used.
Organic fertilizers are derived from animals, plants or natural minerals.
How to apply nitrogen fertilizer
The best way to determine the nitrogen content used in the garden is to conduct a soil test. This result usually details how much nitrogen should be applied per 1,000 square feet. Please contact your local university extension office for details on how to submit a soil test. In the absence of soil test results, the general rule of thumb is to use 1 to 2 pounds of nitrogen per 1,000 square feet of conventional landscaping.
The best time to apply nitrogen fertilizer is in spring, if the soil is light and sandy, before the plant starts to grow; if the soil is heavy clay, it is in late autumn. Please read and follow the packaging instructions when applying fertilizer.
Applying too much nitrogen to your garden or land can cause local groundwater and surface water to be contaminated, so do not exceed the recommended amount, as "the more the better." Excessive nitrate in surface water can damage ecosystems, and drinking water with high nitrate content poses a threat to human health and is associated with increased incidence of cancer.
