Healthy, productive plants need more than just nitrogen, phosphorus, and potassium. They rely on a full spectrum of trace minerals — many of which are missing or depleted in modern soils. Without these essentials, plants develop weak roots, pale leaves, poor fruit set, and reduced flavor.

To help gardeners overcome these challenges naturally, we’re excited to introduce Phytoplankton + Minerals, our most mineral-rich formulation yet. This upgraded product combines the full nutrient power of wild marine phytoplankton with an enhanced blend of key minerals that directly support fruiting, root strength, and vibrant foliage.

If you're growing fruits, vegetables, or leafy greens, this new formula delivers exactly what your crops have been missing.

Key benefits

  • Promotes lush, vibrant leaf growth
  • Strengthens roots and improves fruit quality
  • Enhances flowering and fruit set
  • Improves nutrient uptake and soil balance
  • Corrects common mineral deficiencies naturally
  • Suitable for both soil and foliar use

This formula is ideal for plants that require consistent mineral availability throughout their growth cycle.

All of these advantages come with a 1:25 dilution ratio.

What is the expiration date?  There is none! Or as @rayray_oxygen_entertainment said it is “Eternity and a day”.
You can pre-mix it and store as long as you want. Just shake well before using again.

HOW TO USE

MARPHYL® ORGANIC SOIL ENHANCER

  1. Shake well the bottle of MARPHYL® Organic Soil Enhancer.
  2. Open the bottle. The liquid should look cloudy brown. A presence of some unpleasant smell is normal. The product is 100% natural and is made of decomposed phytoplankton. The smell will dissipate after you mix the Soil Enhancer with water, you can also let the bottle opened for 1-2 days outside and the smell will dissipate on it’s own. 
  3. Fill up your watering tank with enough fresh water to water your plants.
  4. Measure how much MARPHYL® Soil Enhancer you need. The rule is simple – you need 25 times less Soil Enhancer than water.
  5. Add the required amount of MARPHYL® Soil Enhancer into the watering tank. Mix well.
    If you are using a hose with an automatic dispenser, you should regulate your dispenser for 1/25. But you would need to validate the dispenser ratio. Usually, these systems work on an oz per gallon fraction.
  6. Apply the mixture to the soil of your plants.
  7. Repeat the process once every two weeks.
