Products – Fertilizers

” N – P – K ” and ” 21 – 7 – 7 ” What Do They Mean?
All labels on all boxes and all bags of fertilizer have three main numbers on them; such as 21-7-7. These numbers represent the percentage, by weight, of the three main plant nutrients contained in that particular fertilizer package. The first number is always Nitrogen (N). The second number is always Phosphorus (P). The third number is always Potassium (K). The bag of fertilizer may also contain other ingredients, such as iron, sulphur, or calcium. These nutrients will also be listed on the bag of fertilizer if the manufacturer guarantees they are in the fertilizer mix, otherwise a fertilizer may contain some of these nutrients even though they may not be listed on the package. For example, a 100 lb bag of 21-7-7 would contain 21 lbs Nitrogen, 7 lbs Phosphorus, and 7lbs of Potassium. The rest of the bag would consist of‘Filler Materials’ For more information about fertilizers please download a copy of our Plant Nutrient Handout.

Organic Fertilizers
Dr. Earth Fertilizers are excellant organic fertilizers and they incorporate many beneficial bacteria with their fertilizers. The organic fertilizers are derivedDr Earth Fertilizers from fish meal, cottonseed meal, alfalfa meal, fish bone meal, feather meal, soft rock phosphate, kelp meal, and potassium sulphate. With all these sources of fertilizer, the plants benefit greatly. Traditionally, organic fertilizers have been very slow to break down, and it took plants several weeks to start receiving any benefits from the fertilizer. The Dr. Earth company changed this slow process into a faster releasing fertilizer by adding beneficial bacteria to the fertilizer. These beneficial bacteria digest the natural ingredients and release the nutrients in a form that plants can absorb and start to utilize within a few weeks. All of Dr. Earth fertilizers include humic acid, seaweed extract, ecto & endo mycorrhizae, and seven strains of soil building microbes, all of which help improve the soil conditions and help make the plants more vigorous.

Slow Release Fertilizers
Osmocote fertilizer is the best way to fertilize all your container plants. This fertilizer releases slowly, and lasts for an extended period of time. Every time you water you are fertilizing your plants. Osmocote can also be used in the garden areas, but it is a very expensive way to fertilize large areas.Sulphur Coated Urea is another excellent slow releasing fertilizer, especially for lawns. You can fertilize your lawn once in the spring and once in the fall. Your lawn will be green, and grow uniformly all summer long. Sulfur coated urea costs about the same as fertilizing your lawn three times with regular lawn fertilizer but it does save you a lot of time. Many parks and golf courses use this fertilizer exclusively because it does save them time and money

What about Iron?
Iron is Iron Products not part of the three numbers each bag of fertilizer must report. However, Iron is a very important element that most plants require, and iron deserves special attention. Most inexpensive bags of fertilizers do not contain iron. If the bag of fertilizer does contain iron, it will be indicated in a separate area on the bag, and the amount of iron will be listed in the ingredient section on the bag of fertilizer. Example: 21-7-7 Lawn Food plus Iron. This bag of fertilizer contains iron because it is listed on the label.

Most plants in this area do need extra iron because of the soil conditions. Iron deficiencyThe pH of the soil in this area makes any iron, already in the soil, unavailable for plants to utilize. It is a good idea to add a little extra iron, every few years, to help keep plants green. Most types of the iron supplements use a form of iron that is available for plants to use when it is first applied, but it becomes unavailable for plants to utilize after just a few months. Adding gypsum, or sulphur, to the soil will help lower the soil pH,Ironite Fetilizer thus making the iron a little more available for plants to use.
However, in some soil conditions, you would have to add tons of gypsum to make a difference in the soil pH. In those soil conditions it is better to use a form of iron that stays available for plants to utilize in the higher soil pH ranges. ‘Millers Ferri Plus Iron’ and ‘Grow More EDDHA’ are iron products that aree specially chelated for use in the alkaline soil conditions. They remain available for plants to utilize for extended periods of time.

What is Gypsum?
Gypsum handout – Recyling Drywall for Gypsum – How Does Gypsum Work?
Home owners are typically inundated with many sources of information on how to improve soils in the landscape. The claims of some products are almost miraculous in their ability to improve the quality and workability of soils. Other products are firmly entrenched in the minds of gardeners and landscape professionals alike, for their supposed ability to improve soils. Gypsum is one of these products. Advertisements for gypsum often claims the addition of gypsum will help loosen heavy, clay soils, and improve soil drainage. It is also generally thought that gypsum will improve the physical structure of soils. While these claims are not necessarily false in all cases, many homeowners may not see any positive soil improvements from just one application of gypsum.Gypsum will help improve soil conditions, and change the soil structure, but it takes many years. It requires tons – not pounds – of gypsum per acre to change the soil. However, Gypsum does provide many beneficial effects in home gardening and does have a place in your soil’s overall health program.
Magnesium
Is an important nutrient that helps plants grow and stay green. A magnesium deficiency looks just like an iron deficiency. An easy way to distinguish the difference is to look at the leaf veins. If the leaf veins look like they have been drawn with a pencil, the plant needs iron. If the leaf veins look like they have been drawn by a crayon, the plant needs magnesium Magnesium Sulphate is also known as Espom Salt. Most flowers, vegetables and shrubs respond well to extra magnesium. Roses especially show great results: Older Roses – Spread 1/4 cup of magnesium sulphate evenly around each (large) rose bush in April, and repeat in August.
