What is Algoplus?

Algoplus Liquid Fertilizers. Making your plants grow, has just been simplified.

Simply put, Algoplus is a natural liquid fertilizer, 100% completely soluble in water. Algoplus is a 100% mineral based balanced fertilizer designed to deliver the 12 essential nutrients and trace elements that plants need to boost growth, flowers, and fruit. It is non-burning and can be used every time you water. It is non-toxic, environmentally friendly and very economical to use.

Since Algoplus hit the market in the early 90's, it has rapidly become the best known natural fertilizer in the trade. ALGOplus uses only top quality, naturally occurring ingredients to make all of the nutrients your plant requires to grow bigger, better plants available in one easy to use fertilizer. Our natural fertilizers have the most accessible balanced nutrients for your plants available on the market.


This patented formula contains NO Chlorides, NO Carbonates, and NO Sodium.
It’s Odorless, Colorless, and Environmentally Safe!


Whether you have a vegetable, flower or hydroponics garden, or just want to maintain a beautiful lawn, we make fertilizing your plants with naturally occurring nutrients simple! We supply a variety of natural liquid and granular fertilizers and accessories to meet all your plants needs. Great for hydroponics too!



Why does Algoplus work?

Complete. Easily Assimilated. Balanced. Pure.

Algoplus is a special formulation of concentrated, very pure nutrients and trace elements. Every batch is tested for harmful chlorides and carbonates to ensure you receive the highest quality product.


Algoplus Fertilizers are...

Use the tabs below to see how Algoplus fertilizers work to make gardening easier with bigger, better yields.

  • Algoplus enables the grower to work in the best possible condition.

    Good soil management along with proper fertilization is essential to good plant health. Any fertilizer, when added to water, must supply all of the useful mineral salts. Fertilizers can have the same NPK level but have very different nutritive results, depending on the purity and nature of the salts they contain.

    For example, potassium added in the form of potassium chloride is bad for the plant because it introduces chloride, but in the form of potassium nitrate, it is perfectly absorbed by the plant.

    They purity of salts used to produce Algoplus fertilizers allows the plant to absorb all the salts in sufficient quantities, without any risk of blocking or burning its roots. The plant is able to grow in the best possible conditions.

    Algoplus includes a wide range of plant targeted fertilizers totally devoted to the nutrition of household and garden plants... just one capful per gallon of water, and water away!

  • Algoplus supplies all of the nourishment a plant needs for its development and continued growth.

    All plants take from their environment: the air, soil, and water; all the elements they need for their growth. They also take carbon dioxide and oxygen from the air and plants get their hydrogen, oxygen and mineral elements from the soil.

    Nitrogen, Phosphorus, and Potassium (N-P-K) represent the percentage of nutrients contained in this fertilizer. Nitrogen (always the first number) is important to stimulate growth rate and to "green up" the foliage so that it can process nutrients more efficiently. Phosphorus, the middle number, stimulates root growth. And Potassium, the last number, stimulates flowering and fruiting.

    Nutrients from their environment: the air, soil, and water.

    Nitrogen: is the essential component for the growth of the stems and the leaves.
    Phosphorus: stimulates the roots growth and initiates the plant's flowering.
    Potassium: favors photosynthesis, improves the coloring of the flowers, and increases the plant's resistance to the cold, drought and parasites.
    Magnesium: is essential for the making of chlorophyll. It helps in the absorption of phosphorus and is indispensable to the plant's activities of photosynthesis and energy production.
    Calcium: cells component, enables the plant to resist diseases. This element is present in the water found in the soil.
    The 6 trace elements: Boron; Mangan; Molybdenum; Iron; Copper; Zinc

  • The principle of fertilization is based on two fundamental laws: restoration and interaction.

    All the elements are not absorbed in the same proportion, but they are all indispensable. The principle of fertilization is based on two fundamental laws: restoration and interaction.

    The plant's consumption of mineral elements must be compensated for : This is known as resolution.

    The nutritive elements act on each other in a stimulating or antagonistic way : This is known as interaction.

    For example: Potassium has a stimulating effect on magnesium and iron. Phosphorus and calcium are antagonistic.

    Fertilizer added directly to the soil solution is assimilated by the plants root hairs. When the water stimulates these root hairs, the dissolved mineral salts are assimilated and delivered to the main body of the plant. All elements do not play the same or equal role in the plants nutritional needs, however, if there is not enough of an element, then the plant cannot develop properly.

    Algoplus is balanced in such a way as to allow a perfect interaction between all of these nutritive elements. The plant can assimilate what it needs for growth more efficiently and more quickly.

  • The exchange between the soil and the root occurs through the intermediary of the soil solution. This solution must have a pH and conductivity well-adapted to the plant and a perfect balance between the 3 forms of nitrogen: nitric, ammoniacal and urea.

    The pH (soil acidity)

    The pH (soil acidity)
    The pH varies according to the quality of the fertilizer. Some basic fertilizers raise the pH level to 6.5 - 7.

    pH level > 4.5: Good conditions for assimilation of nutrients
    pH level > 6.5 : The non-assimilated elements remain in the soil and raise the conductivity level : the plant growth is stopped.

    Conductivity (EC) : level of salt in the soil solution (generally between 0.8 and 1mS)

    If the soil solution contains more mineral salts than the plant, which can occur naturally or from over fertilization, then the plants water will be attracted into the soil and the plant dries up. This phenomenon is referred to as Reverse Osmotic-Pressure. When the plant contains more mineral salts than the soil solution, the plant gains the nutrients needed for growth.

    Algoplus fertilizers supply a balanced form of natural mineral salts needed by the plants, without changing the conductivity of the soil.

    Nitrogen - Key of fertilization

    Only 1 to 2% of organic nitrogen is transformed into the type of nitrogen available for the plant (mineralization). Only nitric and ammoniacal nitrogen provide the nitrogen nutrition needed by plants.

    Nitrogen exists in three forms: Ammoniacal, Nitric and Urea. Nitrogen is the pivot element in fertilization. Plants are able to absorb nitrogen in its organic form by a complex system of natural bacterial organisms present in the soil. However, only 1-2% of organic nitrogen is transformed into the type of nitrogen needed for plant growth. This is called mineralization. Under normal conditions, there is not enough nitrogen in the soil to sustain good plant growth and leads to withering.

    Algoplus essentially supplies the forms of nitrogen needed for rapid plant assimilation, Nitric (fast assimilating) and ammoniacal (slow assimilating) while maintaining an ideal pH for the plant of the specific formulation.
