Fertilizing is an important lawn care practice, as it influences grass color, ability to recover from stress, and helps prevent weed invasions and disease. There are important features to consider when choosing percenrage fertilizers at the local garden center.

Nitrogen Nphosphorus Pand potassium K are the three major nutrients needed by lawns. Nitrogen is the nutrient required most, although too much nitrogen can cause excessive topgrowth, leading to assorted problems. Percent nitrogen by weight is always the first of three numbers on the nitrogsn bag, followed by phosphorus and potassium. For example, a fertilizer contains 18 percent nitrogen.

This number is important because it determines how much fertilizer is needed. In most cases, a rate of one pound of nitrogen per 1, square feet is suggested for each fertilizer application to the percentahe. If high percentage nitrogen fertilizers are used, then less actual fertilizer product is needed to supply that one pound compared to fertilizers with low percent nitrogen.

Recommended ratios of N-P-K for lawn fertilizers include or Another important factor in choosing nitrogen fertilizers is what kind of nitrogen is actually in the product.

Nitrogen fertilizer may consist of fast-release or controlled-release nitrogen. Advantages and disadvantages are outlined in the table below. For lawns, fertilizers containing controlled-release nitrogen sources are suggested for most applications.

Check the guaranteed analysis information on the fertilizer label for information on what forms of nitrogen are in the product.

Water insoluble nitrogren in slow-release. In addition, a variety of special lawn fertilizers may be found. Winterizer fertilizers are typically high in potassium, and although advertised for fall application can be applied in spring as well. Potassium is used all year nitrogfn grasses, and wbat involved in heat and cold tolerance, disease resistance, and other stress tolerances.

Weed and feed products contain a broadleaf weed killer for weeds such as dandelions fall application ; others contain a preemergence herbicide to control crabgrass spring application.

Lawn starter products, typically high in phosphorus, are whta for newly seeded lawns and freshly laid sod. Sources of organic forms of Nitrogen by their very nature are in a non-burning form and are released to the turf plant over time to varying degrees bases on soil temperature and moisture levels.

There are a variety of organic sources of nitrogen, phosphorus and potassium available to the homeowner. As mentioned earlier most organic fertilizers are derived from plant nirrogen animal sources.

What is a galah in australian sources would include alafalfa and cottonseed meal and seaweed. Examples of animal sources would include bone meal and the nitrogdn from chickens, percetnage and horses.

Yet another source comes directly from mother nature in the form of rock phosphate for a source of phosphorus and green sand for a source of potassium. Find and use products that are locally available whenever possible to keep the input costs ehat.

Feb 03,  · Nitrogen (N) content is the first number. Phosphorous (P) content is the second number. Potassium (K) content is the third number. A bag marked 16 4 8 contains 16% nitrogen, 4% phosphorous and 8% potassium. To determine how much of each is in the bag, multiply the percentage by the weight of the bag. For example, a pound bag: x 50 = 8. Land Product Characterization provides a way to perform statistical comparisons between datasets obtained from disparate sensors. LPCS currently supports MODIS, VIIRS, and Landsat surface reflectance products only, but further development will expand the offerings. Although there are differences between different samples, the amount of "crude protein" (CP) can be found by multipling the percent Nitrogen by a factor (usually ). CP = %N x percent Nitrogen. The percentage of nitrogen found in the orginal sample can now be calculated by: %nitrogen = (gms nitrogen / gms sample) x %N = (gN / gS) x

When you cultivate a garden, you want to make sure your plants grow in the healthiest conditions possible. However, not all soil contains the best amount of nitrogen for plants to grow to their fullest potential.

Use the right types of plant or animal waste to provide your soil with more nitrogen, so your garden can flourish the way you want! To increase nitrogen in soil, try making compost using vegetables, coffee grounds, and other food waste, which will enrich your soil with nitrogen when you use it to garden with.

You can also plant more legume plants, like peas, alfalfa, and beans, which produce nitrogen as they grow. If you're looking for a quick fix, try mixing a chemical fertilizer into the soil to increase the nitrogen levels. Or, go with a slow-release fertilizer, which will last longer and be more effective.

Method 1 of Use chemical fertilizer when you need a quick solution. Synthetic fertilizer is fast-acting and easy to apply. If you're in the middle of a growth season and your plants are suffering from nutritional deficiency, consider using chemical fertilizer to revive them. You can buy a wide range of chemical fertilizers at any home improvement center or nursery.

Over time, synthetic fertilizers diminish soil fertility. Buy fertilizer products tailored to your specific plants. When it comes to chemical fertilizers, the formulas make a big difference. If you're trying to boost nitrogen in your vegetable garden, buy fertilizer made specifically for vegetables. If your lawn needs a nitrogen boost, get a fertilizer formulated for grass. Specific formulas will release nutrients in a targeted way that is ideal for that plant type.

Read the N-P-K numbers on fertilizer labels. All fertilizers are categorized by a 3 number rating system. The first number is nitrogen N , the second number is phosphorous P , and the third is potassium K. These numbers represent the percentage of each nutrient found in the fertilizer. Always check the N-P-K before purchasing a product. Choose a nitrogen level that matches your soil's needs. For example, and are popular nitrogen-heavy fertilizers that will also deliver a small amount of phosphorous and potassium to the soil.

A fertilizer will deliver only nitrogen to your soil. You can use a balanced blend like or if your soil needs all 3 nutrients replenished. Go with a quality, slow release fertilizer. Slow release or controlled release fertilizers may cost a little more, but in the long run they are the best choice.

With slow release formulas, you will be fertilizing your soil less frequently because they are longer lasting. They're also more effective because they release nutrients slowly and steadily. Since chemical fertilizers can negatively affect the soil over time, less frequent applications can help preserve the health of your soil. Slow release fertilizers often come in the form of pellets.

Method 2 of Create compost out of vegetables, coffee grounds, and other food waste. Collecting food waste from your kitchen is the easiest way to enrich your soil with lots of nitrogen.

Start the composting process in early summer so it will be ready by the following spring planting season. Add leftover grass clippings and garden trimmings to your compost. The garden waste you create while manicuring your yard can still be put to good use! Before you sprinkle garden waste into your batch of compost, shred it up into small pieces by hand.

Mix the garden waste into the rest of the compost to distribute it evenly. Otherwise, the grass may rot in a wet mass and leave behind an unpleasant odor. Spread alfalfa meal on top of your soil. Alfalfa meal is very strong; it heats up as it decays, and acts quickly.

Alfalfa meal will provide the soil with plenty of nitrogen, as well as potassium and phosphorus. Plant legume seeds , like peas, alfalfa, and beans. Legume plants are naturally much higher in nitrogen than other types of garden vegetables. As your legume plants grow, they will contribute extra nitrogen to the soil, making the soil richer and giving your other plants the nutrients they need.

Method 3 of Mix feather meal with fertilizer and spread it during autumn. Feather meal is dried and ground chicken feathers. Mix it into your fertilizer of choice before spreading it over the soil.

Work crab meal into your soil before planting your spring crops. Crab meal is made from blue crab organs and shells, and can be obtained from a garden center. Distribute the crab meal with fertilizer across damp soil before running a tiller across the area. The crab meal will not only nourish your soil with plenty of nitrogen, but also protect your plants from being eaten by nematodes.

Move the tiller in straight lines all throughout your gardening area. The nutrients will begin to break down and seep into the soil. Soak fish emulsion into your soil. Fish emulsion is ground up fish parts.

Look for it at your local garden center. Add the fish emulsion to your soil on a monthly basis; make sure to distribute enough for it to soak into the soil. Alternatively, add it to a large amount of water and sprinkle it over your plants. You may want to cover your mouth and nose as you use fish emulsion; it has a very strong, unpleasant smell!

Water your garden with blood meal. Blood meal is dried animal blood. You can obtain it from your local garden center. While the idea of using blood meal to nourish your soil may sound gruesome, blood meal is actually rich with nitrogen. Blend the blood meal with water prior to using it, then distribute it with a simple watering can.

Method 4 of Pick manure produced from poultry or livestock. Sheep, chickens, rabbits, cows, pigs, horses, and ducks are all excellent sources of nitrogen-rich manure. The manure of these animals will nourish your soil with nitrogen and many other nutrients, including zinc and phosphorus.

Use only 6 month old or older manure. New manure contains far too much nitrogen for your dirt to absorb. Too much nitrogen can keep seeds from sprouting after planting, as the excess nitrogen will burn them up at the roots. Put on gloves prior to handling animal manure. Manure can easily spread disease.
