1. Introduction
RAW Phosphorus by NPK Industries is a technical grade plant supplement designed for horticultural applications. This product contains 9% nitrogen and 61% available phosphate, offering the highest concentration of fully water-soluble phosphorus available for home gardening.

2. Setup and Preparation
Before application, ensure you have the necessary tools for accurate measurement and mixing. RAW Phosphorus is a highly concentrated powder that must be dissolved in water prior to use.
- Measurement: Use a precise measuring spoon. Note that 1 teaspoon (tsp) equals approximately 5 milliliters (ml).
- Water Volume: For reference, 1 gallon (gal) equals approximately 3.8 liters (L).
- Mixing: Always dissolve the recommended amount of RAW Phosphorus completely in water before adding it to your reservoir or applying it to plants.

3. Operating Instructions
RAW Phosphorus can be applied as needed in your irrigation system or directly to your plant's reservoir. Moderation is key when using any plant additive.
Application Dosage:
- Add 1/16 to 1/8 teaspoon per gallon of water in your reservoir.
- Apply as needed in irrigation, observing plant response.
General Usage Guidelines:
Begin with very low dosages and carefully observe how your plants respond. Increase the dosage gradually if necessary, based on plant needs and growth stage. This allows for complete control over nutrient delivery.
A 2 oz. package of RAW Phosphorus can make up to 200 gallons of solution, providing ample supply for various gardening needs.

4. Maintenance and Storage
To maintain the quality and effectiveness of RAW Phosphorus, store the product in a cool, dry place. Ensure the packaging is sealed properly after each use to prevent moisture absorption.
5. Safety Information
Adhere to the following safety guidelines when handling RAW Phosphorus:
- Keep out of reach of children and pets.
- Avoid direct contact with skin, eyes, and the respiratory system.
- In case of accidental contact, rinse the affected area thoroughly with water. Seek medical advice if irritation persists or if ingested.
- Do not mix RAW Phosphorus with fertilizers containing chlorine or urea, as this may lead to adverse reactions or reduced efficacy.
- Environmental Consideration: Phosphorus runoff can pose a threat to water quality. Be aware that some states have restrictions on the application of phosphorus-containing fertilizers on non-agricultural lawns or turf. Always check your local laws and regulations prior to purchase and application.
6. Troubleshooting
While RAW Phosphorus is designed for straightforward use, observing your plants is crucial for optimal results. If you notice any unexpected plant responses after application, consider the following:
- Dosage Adjustment: Review your application dosage. Over-fertilization can lead to nutrient burn, while under-fertilization may not yield desired results. Adjust the amount within the recommended range (1/16 to 1/8 tsp per gallon).
- Water Quality: Ensure the water used for mixing is suitable for plant irrigation.
- Environmental Factors: Consider other environmental factors such as light, temperature, and humidity, which can influence nutrient uptake and plant health.
- Compatibility: Confirm that no incompatible substances (like chlorine or urea-based fertilizers) have been mixed with the solution.
If issues persist, consult a gardening expert or refer to additional resources from NPK Industries.
