Nitrogen is known for producing green, lush growth, especially in turf and lawns. While some nitrogen applications might be necessary from the garden as well, usually the chemical ammonium nitrate is used for healthy lawns. This modification is also called nitric acid ammonium salt, nitram, ammonium salt and Norway saltpeter. If you’re using ammonium nitrate on your yard, time it nicely for the best results.
Nitrogen, together with potassium and potassium, is among the most significant elements to a healthy lawn. Although plenty of organic materials, such as leaf litter or compost, include levels of nitrogen, so many people decide to add it to their lawn in the shape of ammonium nitrate. This purer form of nitrogen isn’t natural, and as it’s often avoided by men and women who wish to garden obviously, but it will not make it simpler to add specific amounts and timed applications of the mineral.
Application rates depend on your school of thought, but typically a few nitrogen helps in the beginning of spring. You can either wait until the yard greens up to be certain the grass will have the ability to use the ammonium nitrate most effectively, or fertilize at the first symptom of greening to encourage rapid rise and crowd out weeds. Other fertilization times are in summer and early fall, almost never winter.
Months of Maintenance
Timing is dependent upon several factors: whether your lawn is high- or low-maintenance, whether you leave or cart off clippings, and whether you water. Generally you employ less nitrogen in the event you leave clippings on the lawn, because they add nitrogen themelves, and much less if you irrigate. It also depends upon grass type, climate and price range. Typically, you will want to fertilize once or twice in the spring, usually between April and June, and once or twice in the late summer or fall, around September to November. A cool-season lawn in a greater elevation, for instance, would gain from 1 fertilization in May and repeats in August and September.
There are several accepted methods to calculate just how much of any sort of nutrient you might have to employ, such as ammonium nitrate. The simplest way to calculate, however, is to split the quantity of actual mineral required in pounds from the percent of the nutrient in a particular formula, and multiply the results by 100. Find the sum you want by checking a table which indicates amounts depending on lawn grass type and increasing area. If the result is 6 pounds per 1,000 square feet, split 6 by 33 (because that’s the concentration of actual nitrogen in ammonium nitrate), and multiply by 100. The end outcome is about 18 pounds. Divide this among all the applications which growing season.
