More About us
AOP's focus is on organic or natural plant enhancing products. We carefully evaluate the materials to ensure they do not contain heavy metals or impurities. Many fertilizer materials are by-products of smelters or industry but we avoid using these materials as we only choose the highest grade available.
Effects of Amion Acids on Plants
Every plant like any organism needs certain components for growth over and above soil, sun, rain and air. The basic component of living cells is Proteins, with building block material, Amino Acids. Proteins are formed by sequence of Amino Acids. Plants synthesize Amino Acids from the Primary elements, the Carbon and Oxygen obtained from air, Hydrogen from water in the soil, forming Carbon Hydrate by means of photosynthesis and combining it with the Nitrogen which the plants obtain from the soil, leading to synthesis of amino acids, by collateral metabolic pathways. Only L-Amino Acids are part of these Proteins and have metabolic activity.
The requirement of amino acids in essential quantities is well known as a means to increase yield and overall quality of crops.
The application of amino acids for foliar use is based on its requirement by plants in general and at critical stages of growth in particular. Plants absorb Amino Acids through Stomas and is proportionate to environment temperature. Amino Acids are fundamental ingredients in the process of Protein Synthesis. About 20 important Amino Acids are involved in the process of each function. Studies have proved that Amino Acids can directly or indirectly influence the physiological activities of the plant.
Amino Acids are also supplied to plant by incorporating them into the soil. It helps in improving the microflora of the soil thereby facilitating the assimilation of nutrients.
Foliar Nutrition in the form of Protein Hydrolysate (Known as Amino Acids Liquid) and foliar spray provide readymade building blocks for Protein synthesis.
Protein Synthesis
Proteins have a structural function, metabolic function (enzymes), a transport function and a stock of Amino Acids function. Only L - Amino Acids are assimilated by plants. D - Amino Acids are not recognised by the enzymatic locus and therefore can not participate in protein synthesis. Hence Amino Acids obtained by organic synthesis are not well assimilated.
Stress Resistance
Stress such as High temperature, Low humidity, Frost, Pest attack, Hailstorm, Floods have a negative effect on plant metabolism with a corresponding reduction in crop quality and quantity. The application of Amino Acids before, during and after the stress conditions supplies the plants with Amino Acids which are directly related to stress physiology and thus has a preventing and recovering effect.
Effect of Photosynthesis
Plants synthesize carbohydrates by photosynthesis, Low photosynthesis rate implies a slow growth leading to death of the plant, chlorophyll is the responsible molecule for the absorption of the light energy.
Glycine and Glutamic Acid are fundamental metabolites in the process of formation of vegetable tissue and chlorophyll synthesis. These Amino Acids help to increase chlorophyll concentration in the plant leading to higher degree of photosynthesis. This makes crops lush Green.
Action on the Stomas
Stomas are the cellular structures that control the hydric balance of the plant, the macro and micronutrient absorption and the absorption of gases. The opening of the stomas is controlled by both external factors (light, humidity, temperature and salt concentration) and internal factors (amino acids concentration, abcisic acid etc.) The Stomas are closed when light and humidity are low & temperature and salt concentration are high, when stomas are closed photosynthesis and transpiration are reduced (low absorption of macro & micronutrients) and respiration is increased (Carbohydrate destruction) In this case the metabolic balance of the plant is negative. Catabolism is higher than anabolism. This implies slow metabolism and stops the plant growth.
L-glutamic acid acts as a cytoplasm osmotic agent of the "guard cells". Thus favouring the opening of the stomas.
Chelating Effect
Amino Acids have a chelating effect on micronutrients. When applied together with micronutrients, the absorption and transportation of micronutrients inside the plant is easier. This effect is due to the chelating action and to the effect of cell membrane permiability. L - Glycine & L - Glutamic Acid are known to be very effective chelating agents.
Amino Acids & PhytohOrmones
Amino Acids are precursors or activators of phytohormones and growth substances. L - Methionine is precursor of ethylene and of growth factors such as Espermine and Espermidine, which are synsthesized from 5 - Adenosyl Methionine. L - Tryptophan is precursor for Auxin synthesis. L - Tryptophan is used in plants in L - Form only. L - Tryptophan is available only if hydrolysis of Protein is carried out by enzyme. If hydrolysis is carried out by acid or alkali, as done in many European countries, L - Tryptophan is destroyed. L - Arginine induces synthesis of flower and fruit related hormones.
Pollination and Fruit Formation
Pollination is the transport of pollen to the pistil, so fecundation and formation of the fruit is possible. L - Proline helps in fertility of Pollen. L - Lysine, L - Methionine, L -Glutamic Acid are essential amino acids for pollination. These amino acids increase the pollen germination and the length of the pollinic tube.
Equilibrium of Soil Flora
The equilibrium of the microbial flora of the agriculture soil is a basic question for a good mineralisation of the organic matter and also for a good soil structure and fertility around the roots. L-methionine is precursor growth factors that stabilize the cell walls of the microbial flora.
General
L - Glutamic Acid & L - Aspartic Acid, by transamination give rise to the rest of the amino acids. L - Proline & Hydroxy Proline act mainly on the hydric balance of the plant strengthening the cellular walls in such a way that they increase resistance to unfavourable climatic conditions. L - Alanine, L - Valine & L - Leucine improve quality of fruits. L - Histidine helps in proper ripening of fruits.2

Evaluate The Long Term Consequences
You can probably find something useful in this list to support whichever approach you want to take. The organic vs. non organic fertilizer discussion is likely to continue for some time. Both proponents have strong vested interests in their position.
The roots of the modern chemical fertilizer industry are found in the middle 1800’s. A German chemist, Justus von Liebig, discovered nitrogen and other elements to be essential for plant growth. His book proposed that adding these chemical elements to soil would produce an abundance of food and eliminate hunger in the world.
This noble goal was never realized, though the next century saw chemical fertilizers become the main stream agricultural approach. A British scientist, Sir Albert Howard, questioned this in the early 20th Century. He realized that a more important determinant of plant growth was the health of the soil. He was ridiculed during his life, but his writings later became the basis for the modern organic farming and gardening movement.
Healthy soil produces healthy plants. The health of people, animals, and the environment is improved with using organic vs. non organic fertilizer. It appears the pendulum of change is swinging in the direction of going natural.
Organic Lawn Fertilizer:
It's About Time!
The point is, to get a healthy lawn, you must first make a conscious decision. Do you want to simply have a lawn that is there, and worry about it as little as possible? Or do you want to embark on a program based on sound, wholesome environmental principles that will build up a strong, disease resistant lawn?
Those are trick questions. Either choice does not take you in different directions for lawn care. You get both results when you subscribe to the premise that healthy soil below ground produces healthy trouble-free grass above.
Look at these key features of organic lawn fertilizer, then decide if it’s right for you.
What Exactly Is Natural, Organic Lawn Fertilizer?
It is any natural material containing elements that provide nutrition to plants. This group is quite broad. It basically includes raw, organic (carbon-based) materials derived from plant or animal sources. Examples are alfalfa, blood and bone meal, cottonseed, feathers, fish, kelp, worm castings, manures and compost.
These materials do more than simply add nutrients for plant growth. In contrast, that is the sole purpose of synthetic chemical fertilizer. Organic lawn fertilizers also contribute physical structure and organic material to the soil. These substances interact with everything that exists in the ground. They are essential in providing the optimal conditions for fertile soil and steady, controlled growth.

How Do You Select And Use The Right Materials?
Organic lawn fertilizers and amendments are now readily available. Many companies produce only these type of products. As their value gets recognized, some of the big name chemical companies have also started to offer an organic product line. How do you decide what to try?

Are There Concerns With Using Animal Manure?
Instead of specific, blended organic lawn fertilizer, chicken or steer manures are also used. They are relatively inexpensive. Consider this before applying :
Steer Manure:
Chicken Manure:
Other homemade lawn fertilizer from manure (rabbit or goat) could be used after being fully composted, aged, and screened to a usable particle size.
Do Organic Fertilizers Cost More?
The shelf price is cheaper for many chemical varieties compared to organic lawn fertilizer. However, the best chemical fertilizer types are in slow-release form. They are more expensive, but worth the difference. The cost of organics should be closer in range to these.
Here’s the bonus question. What does it cost to apply a $15.00 bag that needs four or five applications? Try $60-75, plus your time and labor. Or apply natural, organic lawn fertilizer twice a year at $25-30 each time, with half the time and labor. Which sounds like a better deal?
This example depends on you having a lawn that is not starved and desperate for organic material. If so, it is best to apply an extra feeding or two the first year, then cut back to less. Also, organic lawn fertilizers combined with a natural preemergent would cost more. But these may be the best approach to a weed-infested, unhealthy lawn.
Apply less expensive organic soil amendments between each fertilizing to build up the soil. Just a thin top dressing will keep the cycle going.
You Don’t Have To Be An Organic Fanatic
At the garden center, I encountered some reluctance by people to use organic fertilizer. I recommended that they try organic products first for their vegetable garden, then for their flower garden. They could just use the “regular fertilizer” on their lawn. They loved the results with the organics.
Then it struck me. Lawns take the most abuse of all the plants in your yard. Constant mowing interrupts its growth process = stress. Activity of all kinds on it = stress. Why expect grass to do more with less?
Successful athletes place great importance on their nutritional intake. A healthy lawn requires, and benefits greatly from, the same resources. Try going organic! Lawn fertilizer never looked, or worked, so good!
Do You Want To Know What Chemical Fertilizer Can Do?
If You Plan To Use Chemical Fertilizer,
Heed This Advice.
Picture yourself hungry on a busy day. You won’t be able to stop for a meal. You grab a candy bar. It takes the edge off. You go strong for a while. Then you crash.
Picture your lawn. It’s not very green. You give it a dose of super-green-up-nitrogen-fertilizer. You just gave it the equivalent of a candy bar.
It can be that bad. Chemical fertilizer is a short-term solution for a long term need. If using it is your best option, the objective is to lessen any negative impact. You can learn to do that and get better, long-lasting results.
How Does Chemical Fertilizer Affect Plants?
These best selling products from the chemical companies are a synthetic source of nutrients. Grass and vegetables are the hungriest of all the plants in your garden. Nutrients in the soil may not be readily available to them. The plant’s growth or appearance then suffers.
Chemical fertilizers are designed to meet those needs. It is the easiest form of nutrients to apply. They come in many different combinations of ingredients.
The advantage comes by isolating the individual nutrients. You can get different formulas and types for unique applications. Specific products are tailored for specific plants, like grass.
The good effects include the quick uptake of nutrients by grass. This depends on using the correct type at the correct time. More on this below.
The bigger question is how does a synthetic fertilizer affect things in a negative way, even canceling out the good results it produces?
Disadvantages Of Chemical Fertilizer
Why is synthetic fertilizer bad?
When chemical fertilizers don’t work right,
you lose.When they work right, you still lose?
“The more you use, the more it grows. The more it grows, the more you mow. The more you mow…”
…the more you wonder why you wanted a lawn in the first place!
Don’t worry. There’s a way to compensate for all this.
The Composition Of Chemical Fertilizer Affects Results
Each of the nutrients in a formula is for a specific purpose. Nitrogen, phosphorous and potassium are the major elements. The N-P-K ratio you see on the label can tell you a lot. What balance is best for your lawn? (Learn about NPK Fertilizer Numbers.)
Grass needs primarily nitrogen. Chemical fertilizers supply this from different sources. The common types of nitrogen in fertilizer for turf are :
Each type of lawn food will have different amounts of any or all of these nitrogen sources. Why does that matter?
It affects the cost. More importantly, your results depend on using the appropriate type for your lawn. Learn the details at Labels: Understanding a List of Fertilizer Ingredients. (coming soon)

Reading all that information doesn’t automatically translate into making a good selection at the store. Do you want a summary of all those details?
Here are tips for evaluating synthetic fertilizer. Use them to select different products depending on the time of the year and where you need to use it.
Water insoluble or slow-release nitrogen will provide long-lasting green color.
A Better Quality Fertilizer Pellet
More expensive chemical fertilizers usually do offer extra value to go with the price. A homogenous pellet has all the ingredients combined in one little sphere. This is the preferred form, although this feature is not always described on the bag.
The benefit is getting a balanced blend of all the nutrients everywhere you distribute the fertilizer. The alternative is to have each of the elements separate in the bag. They tend to be different sizes and weights. When you spread them, the results are very irregular.
The Very Best Chemical Fertilizer Pellet
You want that pellet to hang around as long as possible, right? Get a formula that is labeled as slow release or controlled release.
If the bag is not marked that way, observe the label for water insoluble nitrogen. This amount should be 20-30% or more. The higher it is, the longer it will last. The terms Ureaform or IBDU also indicate the pellet is coated with a slow dissolving material.
It costs more for a slow release chemical fertilizer. Here is where you save or benefit:
Deal Or No Deal?
Spending money on lawn fertilizer is something that most people would prefer not to do. How do you feel then, if you go to that expense and trouble, and find the results less than satisfactory?
A frequent question at the garden center was: “Do you have any fertilizer that will really work on my lawn?” Change that profile. Start making an investment in your lawn instead of spending, or wasting, money.
What Is Your Final Answer?
Speaking of good, slow-release fertilizers, have you tried any natural fertilizers lately? It’s true that chemical fertilizers outsell organic fertilizers. But…
Could organic fertilizer be a smarter choice?
Before you continue with or embark on a chemical fertilizer program, consider an alternative. It’s worth looking at another option for a task that you’ll be doing for as long as you have a lawn. See The Differences Between Organic vs. Non-Organic Fertilizers.
