How much do I need per half an Acre of Grass?
Is the grass green on the other side?You can use the calculator to determine the amount offertilizer to apply.This tool can be used to help keep your lawn and crops healthy.
Like humans, grass requires a balanced diet for healthy growth.Keeping your lawn supplied with enough nutrition will help it grow stronger, look better and be more resistant to disease.
Nitrogen is the most important mineral in plants.Nitrogen deficiency can cause leaves to turn yellow.
In photosynthesis, energy metabolism, and structural integrity, Phosphorus is an important component.The grass may have slower growth and leaves that are dark green or purple.
Maintaining osmotic potential in plant tissues is one of the roles that Potassium plays.The leaf tips and margins can be affected by a deficiency in Potassium.
Grass needs calcium and magnesium.Sometimes they are present in sufficient levels of the soil.Adding more vitamins may be beneficial if not.Lime and gypsum are used to supplement calcium.
You need to know the species of grass you want to grow so you can give it the right amount of nutrition.
The N-P-K numbers on the label tell you how much of the bag is composed of nitrogen, P205, and K20.
If there is no P or K in thefertilizer, the label will show the hypothetical weight of the two ingredients that would provide the same amount.
A bag of kelp mealfertilizer with an NPK label of 1-0-2 would have the same amount of potassium as a bag with 2% potash by weight.
Slow-release nitrogen is sometimes advertised as controlled release or slowly available.There are a number of advantages to slow-release nitrogen.
Slow-releasing organicfertilizers are also included.A mixture of slow release and fast release nitrogen will give your lawn a quick boost of color without causing burn.
If you live in a cold region, you should be aware of the fact that some organic fertilizers need to be broken down by soil microbes before they will release nitrogen.Nitrogen will not be provided as effectively in cold soils.
For advice on your location, look to your local lawn experts, plant nursery or university extension.Tailoring your fertilization scheme to your soil, grass species, and climate will give you the best results from the NPK calculator.
How much fertilization do you need per acre?
Recommendations may come in different units, but the calculation is the same regardless of the units.
If you wanted to find out how much NPK you need to reach an N application rate of 43 lbs/acre, you would calculate:
Next, divide the rate of fertilization by the area of your lawn to figure out how much is needed.
Use our area calculator to find out if you know your lawn area.If you use our calculator, you will not need to worry about converting units if you match the units used for the application rate.
If you enter in the weight of each bag, the calculator will tell you how many bags to buy.
You can get a more accurate picture of your soil's health by taking a soil test.There are four major advantages.
You can use the soil test to create a fertilization plan for your grass species.
You can save money and prevent over-fertilization by knowing how much your lawn already has.
You will have to mow the lawn more often if you have too much nitrogen in it.Excessfertilizer can burn your grass or become a source of water pollution.
A soil test will tell you if your soil has a high or low pH.The lawn grass has a pH between 6.5 and 7.0.Poor grass health can be caused by the chemical reactions in the soil if the pH is too high or low.
The soil can be adjusted with supplements.You can raise the pH using lime or lower it using sulfur.
The best time to fertilize in winter is in the fall.Fall fertilization gives the grass a chance to build strong roots before the winter, so it will rebound quickly in the spring.The best time to fertilize is in the fall, according to most grass experts.
