There, no fish or most other complex sea life can survive. So for the ongoing health of your plants and our world at large, remember that careful and proper application of any synthetic fertilizer is key. It is imperative that you read and follow the instructions carefully to avoid over-application.
More is definitely not better when it comes to synthetic fertilizer. This lack of oxygen makes the water inhospitable to native sea life. Another common objection against the use of synthetic fertilizers is around the belief that synthetic fertilizers are salt and the concern the salt will harm the soil. Synthetic fertilizers are, in fact, salts — but they are not sodium chloride or table salt. In the world of chemistry, a salt is a compound — the makeup of two or more ions.
Table salt which is very toxic to plants is made up of sodium ions and chlorine ions. Common nitrogen fertilizer made up of Ammonium nitrate is comprised of ammonium ions and nitrate ions, so for that reason, ammonium nitrate fertilizer is also called a salt.
In dry form the two ions — ammonium and nitrate — have come together to form salts. Generally, all forms of salt will harm bacteria and plant roots — if there is direct contact. But when the salts dissolve, the molecules break apart and form individual ions. So as you water a fertilizer into the soil, the water dissolves the salt into ions and washes the ions into the soil.
Each ion has different chemical and physical properties in soil, and they react with the soil environment independently. The actual risks of synthetic fertilizers in soil come when adding these nutrients in very large doses. Phosphorus, the second number in fertilizer ratios, is very effective at establishing growth below ground. Natural, or organic, fertilizer is derived from organic material — plant, animal or mineral origin.
Manure, compost and blood meal are good examples of natural fertilizers. Unlike water-soluble synthetic fertilizers, nutrient transmittal from organic materials is a much slower process. Once organic matter is added to the soil, microbes in the soil bacteria, fungi, algae begin to eat the organic matter. During the digestion process, large organic molecules are converted into smaller nutrient molecules.
At first, the large organic molecules — like proteins and carbohydrates — are huge in size compared to nutrient molecules. They do contain nitrogen, phosphorus, potassium, and more in their original organic form, but those molecules are too big to get into the roots.
Yet as most gardeners know, a bit of patience can be a virtue with greater reward. They remain in your landscape — rather than moving on like synthetics. Also, there is very little risk of burning or dehydration — even in periods of extreme drought or over-application. As an added benefit — each tiny bacteria, fungal spore and other members of that microbial life eventually die off. When they do, they release more of the nutrients consumed during their lifetime.
New microscopic life is born, more organic matter is digested, and the cycle of fertilization continues to thrive. Here are some examples of organic nutrient release rates:. Organic nutrients continue to improve soil, over time, like a fine wine.
Organically-fed soil just get better and better every season. It might not sound appealing to wait for up to six weeks for a benefit, but remember, those benefits will continue on for many weeks and months afterward. In fact, organic nutrients create a nutrient-boost ripple effect. Like fine wine, soil which is provided organic nutrients just gets better and better and better over time.
Organic fertilizers are more expensive, however the money you spend on a synthetic fertilizer is, to some degree, washing away in the leaching process. Meanwhile, the natural fertilizers will remain to benefit your plants and continue to improve your soil health. Read the label to find out how often applications should be made.
In general, applying granular fertilizers just before a good rain can be beneficial, as it aids in working the fertilizer down into the soil where roots can access it.
All water-soluble fertilizers are applied by dissolving the product in irrigation water and then applying it to the leaves of the plant and the soil around the plant. Warning: Do not apply liquid fertilizer at the same time that you plant! No matter how carefully you remove plants from their containers and place them in the ground, some root hairs will break. Many gardeners wait 2 to 3 weeks after planting before fertilizing with liquid solutions; by then, the newly set-out plants should have recovered from any root damage.
It is important to water plants thoroughly with plain water before applying the liquid fertilizer to avoid burning the roots if the soil is dry. Also, take care that the fertilizer is indeed diluted based on instructions, or you could burn the leaves. If you have a watering system, you can use an injector device to run the fertilizer through the system.
In the case of liquid sprays, it is best to apply them on dry days in either the early morning or the early evening, when the leaves will have time to absorb the material. Avoid extremely hot days when foliage is subject to burning. When is your soil ready to plant in the spring? See our minimum temperature for seeds to germinate. Learn how to make your own organic fertilizer at home —from weeds! I am brand new to gardening. I am trying to grow vegetables in containers from seed and some transplanting.
Or should I wait until the young seedlings grow a inches? Thanks for Your help! Assuming you are using liquid fertilizer, be careful to follow the instructions on the product, especially as they pertain to the dilution of the fertilizer before application.
Potatoes require more fertilizer than most garden vegetables. For the home garden not commercial growing :. I like how you mentioned that nitrogen and phosphorus are life-giving nutrients that plants need in order to be maintained and grown. My sister is thinking of looking for dolomite because she's considering planting tomatoes in her garden to increase the variety of homegrown food she has.
I think it's a good idea for my sister to consider buying the necessary fertilizer she needs from a reputable supplier so that her crops can grow as best as possible. It is not just the timing that is important when applying a fertilzer, the weather should be considered as well just like what we do in my garden. Skip to main content. By Catherine Boeckmann.

Not only are they less likely to be able to soak up the nutrients, depending on the fertilizer and method used, the scorching sun can burn and injure plants.
Instead, fertilize plants in the early morning or late evening to avoid any issues and maximize the nutrients. So what are the best natural fertilizing options to use for garden plants?
The key is picking fertilizers that provide a burst of nitrogen, potassium and phosphorous. These are the key nutrients most vegetable plants need most. We prefer using liquid fertilizer over granular. Liquid fertilizers such as compost tea, worm casting tea, or all-purpose liquid organic fertilizers provide a much faster boost to plants.
And they all include the needed ingredients for fast growth. Liquid fertilizers also have the added benefit of being absorbed both through the roots and foliage. For our plants, we apply a quarter gallon of liquid fertilizer to each plant every two weeks for 8 to 10 weeks.

We mulch our plants with a few inches of compost about 8 to 10 inches around each plant. And mixed into that compost is a quarter cup of worm castings to add even more slow-release power.
