Fertilize at the start of summer to keep grass healthy and green throughout the season. Using a fertilizer that slowly releases nutrients over time will help your lawn withstand summer heat and drought conditions.


What fertilizer to use, when to use it and how to use it are questions that you must answer for yourself. The answers depend on the individual plant, its size and stage of growth, the season of the year and whether you see that it needs one particular nutrient or a general purpose product. It will help to know what the major and minor nutrients do for plants. Following is a general description of each.


Refer to the following links to help you decide what your plants need. Remember that too much of a good thing may be too much! Always read the label of any product and follow the directions. Handle fertilizer products carefully, including compost, use gloves and protect yourself from breathing the dust of dry products.


This Partnership is being coordinated with input from stakeholders such as corn grower representatives, fertilizer companies, university researchers, and environmental and industry NGOs. This competition includes two challenges which aim to accelerate the development and use of existing and new product technologies that are affordable to reduce the environmental impacts of U.S. corn production. The results of the Partnership may ultimately be leveraged to improve production of other crops and in the U.S. and abroad.


This Challenge aims to identify concepts for novel technologies for fertilizers and other product technology innovations that can reduce the environmental effects from modern agriculture while maintaining or increasing crop yields. Submissions to the Next Gen Fertilizer Innovation Challenge may include technologies that are not currently on the market or technology concepts that are not traditional EEFs and not in commercial use as a fertilizer.


a. This is related to FAQ#30. We recognize that these precision agriculture hardware and software technologies are important, but they not eligible under these Challenges which focus on novel fertilizers and other product formulations that enhance nutrient use efficiency






Fertilizers are generally defined as "any material, organic or inorganic, natural or synthetic, which supplies one or more of the chemical elements required for the plant growth." Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth. Fertilizers are applied to replace the essential nutrients for plant growth to the soil after they have been depleted.

Excess amounts of fertilizers may enter streams creating sources of nonpoint pollution. Fertilizers most commonly enter water sources by surface runoff and leaching from agricultural lands. Large amounts of nitrogen and phosphorous are present in the runoff. Increased amounts of nitrogen, phosphorous, and other micronutrients can have negative impacts on public health and aquatic ecosystems.


Fertilizers with nitrogen present should be applied as closely as possible to the period of maximum crop uptake. Partial application of fertilizer in the spring with small additions as needed can reduce leaching and improve nitrogen uptake. Fertilizing in the fall has been shown to cause groundwater degradation.


It is necessary to sample soil every year to determine crop nutrient needs for accurate fertilizer recommendations. To calculate the optimal rate of application other sources that contribute nitrogen and phosphorous to the soil should be considered. Organic matter and manure contribute phosphorous. Crops can quickly take up nitrate forms of nitrogen, but are subject to leaching loss. Fertilizer with nitrogen should be limited when leaching potential is moderate to high. If the leaching potential is moderate to high, ammonium nitrogen fertilizers should be used because they are not subject to leach immediately. However, in warm, moist conditions ammonium quickly turns into nitrate. More slowly available nitrogen fertilizers should be used in these situations. Although phosphorous is less prone to leach, loss through surface runoff is common so phosphorous should only be applied as needed and at recommended rates.


In 2022, USDA made $500 million available under the Fertilizer Production Expansion Program (FPEP) to spur domestic competition and combat rising fertilizer costs caused by the war in Ukraine. The Department received applications from more than 350 businesses seeking to increase fertilizer production.


As part of this effort, USDA is inviting public comments on 66 projects eligible to receive grants to increase fertilizer production. The Department will only consider projects that adhere to federal policies designed to protect the environment and historic properties.


Today, the Department is also awarding $30 million in grants through seven awards under round one of the program to help U.S. farmers in Florida, Iowa, Louisiana, Minnesota, Montana, Texas and Wisconsin increase independent, domestic fertilizer production.


Fertilizer prices more than doubled between 2021 and 2022 due to many factors. These factors include: the war in Ukraine, a limited supply of the relevant minerals, high energy costs, high global demand and agricultural commodity prices, reliance on imports, and a lack of competition in the fertilizer industry.


In January 2023, USDA released a list of 21 potentially viable projects for the first round of funding with a request for public comment. The first round focused on projects that will increase fertilizer capacity for the 2023 or 2024 crop years, to prioritize projects with near-term impact.


The purpose of the fertilizer program is to provide landscape professionals and homeowners science based guidelines for fertilizer use and other landscape practices that, when followed, reduce the loss of soil nutrients from excessive, incorrectly timed, or inappropriate fertilizers. On Nantucket, lost nutrients find their way rapidly to the coastal waters, harbors, ponds, and streams where they may cause contamination that is harmful to aquatic organisms as well as to human health and welfare.


This technique, which provides nutrients to individual plants such as shrubs and perennials, is done by hand with granular fertilizers. Simply apply the fertilizer around the base of the plant, extending to the drip line. For vegetables, place the fertilizer in a strip parallel to the planting row.


In addition to N-P-K, most fertilizers contain traces of other elements important to plant health. Some trace elements are more important than others, but each nourishes a plant in its own way. The main trace elements in fertilizers are calcium, magnesium, iron, copper, manganese, zinc, molybdenum, boron, and sulfur. (You can usually purchase these items individually as well.) If any of these elements is lacking, a plant may show characteristic deficiency symptoms. An iron deficiency, for instance, causes chlorosis (yellow leaves with green veins), which is easily corrected with a dose of chelated iron.


There are two types of fertilizers available to the home gardener: granular and water soluble. Each type has advantages and disadvantages. Granular fertilizers deliver food to a plant slowly but have the advantage of longevity. Since they must be broken down by water before a plant can use them, granular fertilizers do not leach out of the soil as rapidly as water-soluble types. Water-soluble fertilizers are faster acting but more transient, which means they must be applied more frequently than the granular type.


Both types of fertilizers are effective, so the one you choose depends on whether you want to give your plants a quick but frequent fix or a sluggish but extended feeding. And for those of us gardeners who are oh so very busy (or oh so very lazy), nothing beats time-release granular fertilizers, some of which require only one application every six to nine months.


A funny article that I think would be interesting for you, and your other readers is one I stumbled across a few days ago. It's about why you should talk to your plants haha.

The effects of COVID-19 and international conflict are driving fertilizer prices to record high levels, increasing farmer costs. These factors, combined with climate change, are causing major disruptions for global food systems, threatening global food security. At the same time, significant quantities of applied nitrogen fertilizers never reach the intended crop, reducing yields and creating environmental concerns. Advancing fertilizer use efficiency and alternatives can reduce the impact of fertilizer shortages on food security, while also reducing nitrous oxide pollution.


Numerous innovative fertilizer products are currently available; however, there is little independent information validating the efficacy of these products and how they compare to other products. Without information about practices and products that work in specific farm systems and climates, farmers cannot make informed decisions about their nutrient needs.


The Efficient Fertilizer Consortium will address these challenges by funding applied research that accelerates development and wider adoption of novel fertilizers that increase nutrient-use efficiency and reduce direct emissions of nitrous oxide and other greenhouse gases from fertilizers. The Consortium is a vehicle for collaboration and exposure to new ideas that also leverages resources, de-risks research and development and accelerates solutions for end users.


FFAR is leveraging $4.45 million from the U.S. Department of Agriculture, and actively seeking matching funders, to amplify investment in pre-competitive research that accelerates novel solutions to common challenges facing the fertilizer industry.
