How To Measure Your Lawn For Sod

Measuring Your Lawn

Heres how to measure your yard for sod. Grab a piece of paper and draw the areas to be sodded. Break up the areas into the shapes listed below. Measure the areas and write down your measurements. Now, enter your measurements into our Sod Area Calculator. Or, figure out the sq.ft. of your areas based on the equations listed below and total.

Square or Rectangle

To figure the area of a square or rectangle, measure the Length & Width and multiply.Length x Width = Area12 x 24 = 288 sq.ft.

Right Triangle

A Right Triangle has one 90º corner. To figure the area of a right triangle, multiply the two sides that contact the right angle and divide by 2Length x Width / 2 = Area12 x 24 = 288 ÷ 2 = 144 sq.ft.

Circle, 1/2 Circle, 1/4 Circle

To figure the area of a circle, take the radius times the radius, then multiply by 3.14. Radius is a straight line from the center of a circle to the outside of the circle. x 3.14 = Area6 x 6 = 36 x 3.14 = 113 sq.ft.Half Circle divide by 26 x 6 = 36 x 3.14 = 113 / 2 = 56.5 sq.ft.Quarter Circle divide by 46 x 6 = 36 x 3.14 = 113 / 4 = 28.25 sq.ft.

Measuring Fertilizer Application Rate

The fertilizer application rate is dependent on your plants nutrient needs and the formula. Nitrogen is the most important nutrient as it determines its growth and utilizes the chlorophyll within the plant.

Start a soil test to measure the potassium and phosphorus within the fertilizer. Most soils have an ample amount of these components, so you dont have to add too much. Giving your soil too much of these nutrients will lead to increased salt levels within the soil.

How much fertilizer will you need for a large area? Determine the square feet of the area and divide that by the recommended amount of nutrients of the plant by the recommended amount of nutrients for the fertilizer.

While weighing fertilizer appears complicated, it is the best way to utilize space on your lawn. Find the NPK ratio that works best with your soil and spread it evenly. By doing this, youll utilize your garden and give it the nutrients needed for long-term growth.

Calculating Npk In Liquid Fertilizers

The first thing that you need to know when calculating the weight of Nitrogen, Phosphorus or Potassium in your fertilizer is to figure out the percentage rates of N-P-K.

The rates are expressed as three numbers separated by dashes. They will be on the packaging of your fertilizer and look like this: 16-4-8.

We will use our 1 Gallon Advanced 16-4-8 Lawn Food for this example.

The first number represents Nitrogen, the middle number Phosphorus, and the third number all the way to the right is Potassium. This means that 16% of the product is made up of Nitrogen, 4% of Phosphorus, and 8% Potassium.

First, you must figure out your products weight. This number is on the packaging represented in pounds or kilograms . For this example, we will take the product weight per gallon and multiply it by the percentage of our nutrient . A gallon of this product weighs approximately 10.32 pounds.

Total weight of product x percent of Nitrogen = Pounds of N in 1 gallon

10.32 x 0.16 = 1.65

Now you must determine what is the amount of N per ounce. Since there are 128 ounces in 1 gallon, we will divide the weight of N by 128 ounces. This will help you determine how much product to water ratio you need in your backpack sprayer.

Weight of N / Total Ounces of Product = Amount of N per 1 ounce

1.65 / 128 = 0.0129

Ounces per 1,000 square feet x Nitrogen per 1 ounce = Total weight of N per 1,000 square feet

10 x 0.0129 = .129 pounds of Nitrogen per 1,000 square feet

How Big Is Your Lawn

A key step in most lawn maintenance practices such as seeding and fertilizing as well as with double-checking your calibration and application accuracy is to determine the size of the turf area. Determining your lawn area will help you calculate how much seed you need, how much sod to order, how much fertilizer to apply, how much pesticide to measure, and more.

The best way to do determine the area is to divide your turf into several squares, rectangles, or circles . Calculate the area of these smaller shapes and then add them together to determine the total size of the turf.

Figure 2. An example property with dimensions for its lawn, hardscape, landscape, and house.

Area Calculation Example This example illustrates how you might calculate the area of your lawn. The measurements for this example come from Figure 2.

In this example, the easiest method is to calculate the total area of the property, and then subtract the hard surfaces from that to get the total area of the lawn.

How Much Fertilizer Do I Put On The Lawn? EASY Formula for BEGINNERS.

Calculating the amount of fertilizer in your turfgrass or gardening program can be a bit confusing. Just like the human body requires vitamins, minerals, and nutrients, so do plants. Keeping your lawn and garden supplied with the correct amount of nutrients will help it grow stronger and greener, and increase yields. A healthier lawn and garden will also fare better in its disease resistance.

Determining The Amount Of Fertilizer To Use

After finding your lawns total square footage, you can check the label on your fertilizer for the percentage of nitrogen that it contains. In order to find this number, look for a three-number series on the bag. Nitrogen will always be the first number listed. Next, determine the pounds of fertilizer you will need to apply based on the percentage of nitrogen, printed recommendations on the bag, and the pre-calculated square footage of your yard.

Best Lawn Fertilizer Ratio

The standard ratio recommended when fertilizing your lawn is 3-1-2 however, this is not constant because you would need to determine the number of existing soil nutrients to avoid over-fertilizing problems or one fertilizing.

Most fertilizers package their products with a predetermined ratio, so all you need is to apply.

How Much Should I Water My Lawn After Fertilizing

The amount of water available beneath the ground on your lawn is directly proportional to the amount of available fertilizer, so the more you water your lawn, the more you must be required to fertilize your lawn.

Be sure to keep a balance between the amount of fertilizer needed and water to achieve consistent growth within your lawn.

You can capitalize on mechanized watering systems, such as the use of a sprinkler to ensure that your lawn is evenly watered. Again, the type of fertilizer used will determine the frequency of watering on the lawn.

Know Before You Grow: How to Calculate the Right Amount of Fertilizer ...

In short, there are three main elements required to properly feed and fertilise your lawn effectively and efficiently, they are Nitrogen, Potassium and Phosphorus.

So, before choosing the best fertiliser you must understand what these three elements do:

Nitrogen gives your lawn its rich, green colour and creates strong, sturdy leaves.

Potassium works with N to make the roots and foliage stronger. It gives your lawn a greater chance of resisting drought, wear and tear as well as pests and diseases.

Phosphorus works underground making your lawns roots strong, especially heading into winter.

A good quality fertiliser contains all the main elements that your lawn requires and is suitable for your lawn type.

Good quality fertilisers can either be liquid or granular depending on your budget and lawns requirements.

How Often To Fertilize A Lawn

The recommended frequency for fertilizing your lawn can be anywhere between 5-6 times per year. It would be better to fertilize your grass when its growth rate is at its peak.

However, it would help consider other factors such as the prevailing climatic conditions and the season for better results.

Measuring Your Lawn The Right Way

Measuring your lawn is more than just throwing a tape measure around. Rarely is a lawn a perfect square, and you can almost always rely on something blocking you from measuring in a straight line from one end to the other.

Using a copy of the documents showing your property lines and an aerial view of your home from Google Maps, break your lawn into small, measurable sections. Make the sections as square as possible to ease the calculation process and number them for easy tracking.

With the sections mapped out, there are a few ways to get the measurements you need. You can go old school with a tape measure or measuring wheel, or you can venture into the 21st century and let a computer do the work with estimating software.

What Do You Do If You Burn Your Lawn With Fertilizer

Water your lawn with a sufficient amount of water as soon as you spot patches on your grass.

The first sign of excess fertilizer application on grass is the appearance of yellow and brown patches on the grass. This effect can be undone by watering the lawn adequately before the damage becomes permanent.

Chances of your grass experiencing sun damage are high during this phase, so the best time to water the lawn is in the early morning and the evening.

Allow the affected area a few, days and if they are no significant change, uproot the affected patches to allow for new grass growth.

Plan Your Route Half Your Material

One of the biggest mistakes people make when using a broadcast or drop spreader is to put all of the material needed to seed, fertilize, or treat their lawn in the hopper.

Do so and you risk running out of product before you finish walking your lawn .

Its a big problem heres how to avoid it:

  • Once you calculate your lawn size and understand how much material you need to spread in that area, split your fertilizer or seed in half. Add half to the hopper, and start by putting a header strip around the perimeter of your lawn area
  • Next, finish spreading the first half of your fertilizer by traveling back and forth across your lawn inside your header strip.
  • Finally, load up the other half and walk in the opposite direction across your entire lawn.

This allows you to get complete, even coverage across your entire yard while applying the perfect amount of fertilizer, grass seed, soil amendment, or herbicide product.

Header strip followed by North to South fertilization path for the first half of your fertilizerSpread the second half of your material in an East to West pattern to ensure even coverage across your entire lawn

And if you are applying liquid fertilizer or herbicide across your lawn, you can take a similar approach to ensure even coverage and to make certain you arent wasting any of your material on the street, sidewalk, or walkways around the perimeter of your yard.

What Days Of The Month Are You Fertile

Ovulation happens about 14 days before your period starts. If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14. If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and 21.

Choose Your Strategy For Measuring

Fertilizer Chart
  • You can do this the old fashioned way, which is to break out a long tape, a measuring wheel, or, even in the case that Im doing here, a twenty-five foot tape measure, and literally measure each area out in the lawn, record it here on your map, and come back in and do your calculations.
  • Or, the easier way and probably the more modern way, is to use online tools, like you see here, that are going to allow you to do something very similar by outlining areas of the lawn and then theyll give you the area automatically calculated. In the end, what you should have is a nice, sectioned map that tells you how big each area of your lawn is, and then a total square footage at the end. Keep in mind that rounding up or down to the nearest one-hundred is just fine. And now that you have a proper map with measurements of each area of your lawn and a total, you should feel more confident in applying lawn applications knowing that your better following the labelled rates.
  • Additionally, knowing your lawn size can help you choose the right lawn mower for your situation. Do you need a smaller deck? Or a wider one thats going to cut more area a lot quicker? For me, of course, the more I get to mow, the better.
