Lawn Fertilizer Services To Nourish Your Yard
It's important to fertilize your lawn because grass can remove nutrients from the soil as it grows. Over time, this process leads to depleted dirt and decreased grass growth. Fertilizing a lawn can restore the pH and nutrient makeup of the soil in your yard.
Types of FertilizerFirst, you'll want to select the type of fertilizer you'd prefer for your lawn. Fertilizers are made up of three primary elements: nitrogen (N), phosphorus (P), and potassium (K). The amount of each ingredient varies based on fertilizer type. The NPK value of a fertilizer displays the percentage of each element in the mixture. For example, an NPK value of 10-11-12 would contain 10% nitrogen, 11% phosphorus, and 12% potassium.
Common options for fertilizer are as follows:
Factors such as where you are located, your grass type, your lawn's health, and the condition of your soil will determine how frequently you should fertilize. Experts agree that fertilizing two to six times per year is ideal, often around mid-spring, Labor Day, and the end of October. However, a soil analysis is the best way to discover what your yard needs.
You'll want to fertilize starting in the late spring if you have warm-season grass such as zoysiagrass, St. Augustine grass, or Bermuda grass. Start when the grass is already growing and continue through the summer months. Cold-season grasses, such as Kentucky bluegrass, ryegrass, bentgrass, and fescue grass, should be fertilized during the same window you start mowing in the spring. After the first application of fertilizer, you'll want to pause until after Labor Day. Apply fertilizer through early fall, and then administer the final treatment by the midpoint of the autumn season.
Regardless of grass type, homeowners should stop fertilizing roughly six weeks before the first frost in your region, as fertilizing too close to winter can weaken your grass and soil throughout the cold months.
Spreading FertilizersNo matter the type of fertilizer you choose, you'll want an even spread of nutrients throughout your lawn. Fertilizers can be spread through several mechanisms:
Fertilizer Companies Cash In While Farmers And Communities Struggle
On a small vegetable farm in Georgia, Shad Dasher used to grow watermelons every year.
Last year, he didn't plant any.
Dasher, 56, said it was because of elevated fertilizer prices. Like many farmers, Dasher is finding it hard to stay afloat. "The American public just doesn't understand what kind of beating our group (of farmers) has been taking over the years," he said.
Although fertilizer prices have fallen from their all-time high in March 2022, when they spiked up to 3.5 times higher than two years before, the commodity is likely to remain costly for some time, continuing to squeeze the food production system.
Meanwhile, the fertilizer industry has yielded record profits. Canada-based Nutrien Ltd., the world's leading producer of potash fertilizer, saw profits increase 1575 percent between 2020 and 2022, to $7.7 billion. Florida-based Mosaic Co., one of the largest US producers of potash and phosphate fertilizer, netted $3.6 billion in 2022, a 438 percent increase from 2020. CF Industries, an Illinois-based fertilizer company, made $3.2 billion in 2022, a 955 percent increase from 2020.
The eye-popping figures have heightened concerns about consolidation in the fertilizer industry, even as the Biden Administration moves to boost domestic fertilizer production.
When asked for comment, Mosaic said in an email that the fertilizer business is cyclical and thus has volatility in prices. CF Industries did not respond to requests for comment. Nutrien did not provide a statement by press time.
Global disruptions help drive up pricesThere are a few clear reasons for the recent record fertilizer prices. The onset of the COVID-19 pandemic in 2020 caused disruptions to the supply chain and labor shortages that hindered production of natural gas, a major ingredient in fertilizer.
Then came a series of natural disasters, such as the February 2021 deep freeze in Texas, which froze natural gas wells and drove up demand for residential heating. In August that year, Hurricane Ida disturbed natural gas and fertilizer production in the Southeast.
Another factor was a reduction in exports from China, the world's leading producer of phosphate, a chemical element that is a key component of fertilizer.
The war in Ukraine further tightened the market as Western countries sanctioned Russia, the world's top fertilizer exporter. Disruptions in natural gas flow from Russia led to spikes in European natural gas prices and forced several European fertilizer plants to close or cut output.
Even low water levels on the Mississippi River contributed to price increases, as it limited the amount of fertilizer that could be shipped by barge.
"There were a myriad of reasons why we were seeing this big run up in fertilizer prices. It's not just one thing. It was literally a whole menu of things that were seemingly going in the wrong direction if you were looking to obtain fertilizer," said Chad Hart, an agricultural economist at Iowa State University.
Several of these factors are referenced in a study Hart co-authored that was hailed by The Fertilizer Institute for providing "the best analysis data will allow to date." But some argue the study omits a large factor of the price increase: market power as a result of consolidation.
Allegations of market manipulationFarm Action is a Missouri-based nonprofit organization that advocates for competitive food and agriculture systems across the United States. Co-founder Joe Maxwell believes consolidation in the fertilizer industry has led to market manipulation.
Since 1980, the number of fertilizer firms in the United States has fallen from 46 to 13. In 2019, just four corporations represented 75 percent of total domestic fertilizer production: CF Industries, Nutrien, Koch and Yara-USA, according to Farm Action. And just two companies supply 85 percent of the North American potash market: Nutrien and Mosaic, according to the Federal Trade Commission.
"These companies took advantage of their dominant position in a marketplace and increased commodity price to the farmers in an effort to price gouge and extract all the wealth that they could from that supply chain at the very roots: fertilizer," Maxwell said.
[RELATED: Facing High Fertilizer Costs, Farmers Still Struggle to Use Less]In 2021, the United States imposed tariffs on fertilizer imports from Morocco and Russia following petitions from Mosaic and CF Industries. Growers widely derided the move. A letter from the National Corn Growers Association to Mosaic accused the company of "irresponsible" practices that "manipulate the supply curve" and "dictate price to farmers."
Later that year, Farm Action wrote a letter to the Antitrust Division of the Department of Justice accusing the fertilizer industry of using its "monopoly power" to fix prices, requesting an investigation. Iowa Republican Sen. Chuck Grassley seconded that call, but no investigation has yet been announced.
Mosaic said in an emailed response that since the tariffs took effect, foreign producers importing fertilizer into the North American market has increased, and by extension, made the market more competitive.
In a company Q&A, a Mosaic official, Andy Jung, said the tariffs are not the reason for the price increase and that the current market is not driven "merely by a ruling for fair trade."
The effect of consolidationPresident Joe Biden issued an executive order in 2021 promoting competition in the economy, including the agriculture sector and the fertilizer industry specifically. "Consolidation in the agricultural industry is making it too hard for small family farms to survive," the order reads.
In response to the order, the US Department of Agriculture collected comments from agricultural producers on competition, access to fertilizer and supply chain concerns. From more than 1,600 responses, 72 percent described concerns about the power of fertilizer manufacturers and 62 percent described what they saw as unfair price-setting practices.
While the study from Iowa State University does acknowledge market consolidation, it dismisses it as a factor of price increase. Hart said he sees the consolidation, but can't prove manipulation in such an unstable time.
"You just can't separate out what's happening and whether there is a competition problem in this market or not," Hart said.
While many factors have made the ingredients for fertilizer more expensive, the increase in profits is disproportionate to the increase in production costs – basically, companies are making a lot more money than they're spending.
In 2022, Nutrien's cost of goods sold increased by 24 percent compared to the year prior; however, its profits were up 142 percent from 2021. CF Industries saw its profit increase by 212 percent in 2022, while the cost of manufacturing and sales was only up 28 percent. For Mosaic, profits were up 120 percent in 2022, but cost of sales only increased by 46 percent.
Although corn farmers enjoyed the highest corn prices on record in September 2022, their profits were offset by increased fertilizer prices.
"These [fertilizer] corporations are well aware of their leverage and have used the cover of consecutive global crises to raise prices far beyond those demanded by necessity," Farm Action said in a comment to the USDA.
Farming communities hit hardestSmall farmers, business owners and rural communities have struggled to pay bills amid these record costs and industry profits.
Gary Hamilton owns a small business in northeast Missouri called Frankford Farm Supply, where he sells fertilizer and farming equipment. He started the company about 30 years ago.
Hamilton's store is down the road from one of many corporate-owned Nutrien stores scattered across rural America. Hamilton said that Nutrien's prices are lower and he just can't compete as a small family-owned business with less than 15 employees.
When fertilizer prices go up, Hamilton's credit limit doesn't. This means he may not be able to serve as many customers as he used to, and those customers have to turn to other stores.
"Because of the high prices, I actually lose business. And when I lose business, then I have less money to pay for health insurance, fuel, salaries, wage increases, day-to-day things that businesses need to survive," Hamilton said.
Fertilizer prices are expected to fall eventually, with lower demand from farmers helping to rebuild supply, experts say. But it will be hard to lessen dependence on fertilizer anytime soon. While farmers and small business-owners may complain about fertilizer prices, they will continue to pay for it, Hart said, because their business—and the food supply—depends on it.

Master Gardener: How To Keep Your Lawn Free Of Weeds
Q. I enjoy reading your column in the Saturday Orange County Register. I live in Anaheim and have a St. Augustine lawn. I am having difficulty finding a suitable fertilizer and/or weed control product. There are plenty of alternatives, but they all are labeled as not suitable for St. Augustine. I called a well-known company, and they recommended one of their products, but it can't be shipped to California. In the past, I have always used sulfate of ammonium on the lawn but really need a weed and feed product to rid my lawn of the weeds. Any suggestions or advice would be appreciated!
Most species of turfgrass can tolerate broad-leaf herbicides (such as 2,4-D) targeted toward the most common lawn weeds. St. Augustine is not one of those grasses.
St. Augustine grass is ideal for mild coastal climates (such as Orange County). It will become dormant or semi-dormant in the winter with a growing season that runs from March through October. Since it is a sensitive princess grass, it tends to shrivel up and die if it's exposed to any kind of weed control.
As you've discovered, the only effective weed control is unavailable in California.
My best advice is weed prevention. When you mow, set the mower to the highest level (preferably 2 inches, but certainly no lower than 1 inch). De-thatch in the spring and apply 4 pounds of nitrogen per 1000 square feet over the course of the growing season (not all at once!). Apply an iron supplement such as Ironite since St. Augustine tends to suffer from iron deficiency. Water deeply every 3-6 days. Deep watering will encourage deep roots and discourage weed growth since weeds thrive on frequent, shallow watering. A thick, healthy lawn will out-compete weeds easily. Although it may not eliminate every weed, it will make things more manageable.
Q We planted several fern trees for privacy. Our neighbor has planted a eucalyptus tree on the other side of the fence. Will this cause any problems?
I am assuming that you planted Australian Tree Ferns. These plants grow well in a partial shade, higher humidity environment. I would not be concerned about the neighbor's eucalyptus casting shade on your tree ferns.
However, eucalyptus trees grow quickly, and their wood is brittle. If the eucalyptus is too close to the shared fence, I would be concerned about their tree pushing against the fence after a few years.
Eucalyptus is native to Australia, so how did it end up in America? Well, the railroad companies traditionally used oak for their railroad ties since it's a heavy, dense wood. Oak takes a long time to grow big enough to harvest for railroad ties, so the railroad companies imported eucalyptus because they grew quickly. Unfortunately, when the train rolled over the eucalyptus ties, the wood simply crumbled under the locomotive's weight. So now we're stuck with all these eucalyptus trees that aren't good for much of anything.
