# How many square feet does a 50 pound bag of fertilizer cover?

Now that you know 3.8 lb of 26-5-10 fertilizer will cover 1000 sq ft, determine how many times 3.8 lb goes into 50 lb. 50 lb ÷ 3.8 lb = 13.2. Now multiply 13.2 by 1000 sq ft: 13.2 × 1000 sq ft = 13,200 sq ft. Thus, a 50-lb bag of 26-510 covers 13,200 sq ft at a rate of 1.0 lb nitrogen per 1000 sq ft.

Beside this, how is fertilizer ratio calculated?

How to calculate a fertilizer ratio. If your soil test report recommends applying 1.5 lb of nitrogen, 0.5 lb of phosphate, and 0.5 lb of potash per 1000 sq ft, you should apply a fertilizer with a ratio of 3-1-1 since you need three times as much nitrogen as phosphate and three times as much nitrogen as potash.

How much fertilizer does it take per acre?

(2) Amount of product needed to apply 43.5 pounds of nitrogen per acre. To determine the amount of product needed to deliver 1 pound of nitrogen per thousand square feet, divide 100 by the first number in the fertilizer ratio. For example, for 16-4-8 fertilizer, divide 100 by 16.

How much urea fertilizer do I use per acre?

Application. Specialists at the University of Minnesota recommend applying urea at a rate of 10 pounds per acre at planting time when conditions are moist and at a rate of 20 pounds per acre when conditions are dry.

10.86 pounds

## How many cups are in a pound of fertilizer?

100 is 1/10th of 1000 so… 1/10 of 20 lbs equals 2 lbs. So I need 2lbs of fertilizer per 100 sq feet. 1 cup of garden fertilizer weighs about ½ pound. So for 2 lbs you would need 4 cups of 10-10-10 fertilizer.

## How many units of nitrogen are in a pound of urea?

Urea contains 920 actual pounds of nitrogen per ton, and ammonium nitrate contains 680 actual pounds of nitrogen by ton (2,000 x 46% = 920 and 2,000 x 34% = 680).
It weighs 11.08 lbs. per gallon, has a pH of approximately 7 and has a negligible vapor pressure. Each gallon of UAN 32% Solution contains 3.55 lbs. of N.

## What is 46 0 0 fertilizer used for?

Urea is 46% nitrogen, so its analysis is 4600. This actually has carbon in it, so in a sense, you could call it an organic nitrogen. Not that it’s approved for organic use, but it does have carbons in with the nitrogen so carbon is part of the molecule of urea. Urea is a high analysis dry nitrogen.

## What kind of fertilizer is 0 0 60?

5. Potassium Fertilizers. Potassium chloride (0-0-60) is the most commonly used source of potassium. Potassium chloride is mined as sylvinite from underground mines or by solution mining in New Mexico, Utah, California, and Michigan.

## What is 21 0 0 fertilizer used for?

As its name, and chemical formula denote, Ammonium Sulfate, is a two-in-one fertilizer. Its crystal form, and 2100 analysis, are one of agriculture’s oldest solid forms of fertilizer.
Ammonium sulfate [(NH4)2 SO4] was one of the first and most widely used nitrogen (N) fertilizers for crop production. It is now less commonly used, but especially valuable where both N and sulfur (S) are required. Its high solubility provides versatility for a number of agricultural applications.

## Why is ammonium sulphate a good fertilizer?

Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth.

## What does ammonium sulfate do for grass?

It can be applied to lawns as a top dressing of nitrogen and sulfur with a broadcast or drop-type spreader. In areas with high pH soils, the sulfur in ammonium sulfate helps lower soil pH levels. As with other fertilizers, water the treated area well after each application.
Nitrogen and sulfur are elemental nutrients required by most plants. As a result, ammonium sulfate also acts as a fertilizer. Ammonium sulfate is a weaker source of acidic compounds than elemental sulfur or aluminum sulfate.

## Why is ammonium sulfate used in bread?

In baking applications, ammonium sulfate is used as a dough conditioner and dough strengthener in bread products. Ammonium sulfate supplies nitrogen to the yeast for nourishment aiding in yeast function while promoting browning.

## How much sulfur is needed to lower soil PH?

Use about 4 to 6 lb. of aluminum sulfate per plant for most medium- and fine-textured Wisconsin soils in order to decrease soil pH by about one unit. If elemental sulfur is applied, decrease the total recommended application by one-sixth. One pound of aluminum sulfate or elemental sulfur is equal to about 2 cups.
Coffee grounds are a good addition to the compost pile. I am not overly concerned about using them as a mulch, but it might harm some plants – nobody knows. It is doubtful that they have a great effect on pests, but unless the grounds are very acidic, they will NOT acidify your soil.

## Can you use vinegar to acidify soil?

To lower the pH level of soil and make it more acidic, vinegar can be applied by hand or using an irrigation system. For a basic treatment, a cup of vinegar can be mixed with a gallon of water and poured over soil with a watering can.
Part 2 Acidifying the Soil
1. Identify your soil type.
2. Add organic materials to well-drained, loose soils.
3. Add elemental sulfur to soil that is heavily compacted or which has lots of clay.
4. Add iron sulfate to soil that is heavily compacted or has lots of clay.
5. Use a fertilizer containing ammonia.
When we first started doing this show, we warned people to only spread coffee grounds around acid-loving plants, like azaleas, rhododendrons and blueberries, because the grounds were bound to be acidic; and not to overdo it on those and other flowering plants, as the grounds were certainly high in Nitrogen, which makes
For this reason, you should be using a high acid fertilizer, especially in an area where you have had to amend the soil in order to lower the pH enough to grow your blueberries. When looking for a high acid blueberry bush fertilizer, look for fertilizers that contain ammonium sulfate or sulfurcoated urea.
For instance, you can sprinkle fresh coffee grounds around acid-loving plants like azaleas, hydrangeas, blueberries, and lilies. Many vegetables like slightly acidic soil, but tomatoes typically don’t respond well to the addition of coffee grounds.

## How much urea fertilizer do I use per acre?

Application. Specialists at the University of Minnesota recommend applying urea at a rate of 10 pounds per acre at planting time when conditions are moist and at a rate of 20 pounds per acre when conditions are dry.
