Modern agriculture increasingly focuses on efficient nutrient management. Farmers need fertilizers that can be applied conveniently through irrigation systems and foliar applications while supplying nutrients according to crop requirements. Water Soluble Fertilizers (WSF) are an important category of crop nutrition products used for this purpose.
Urban Green Crop Science offers a range of water-soluble fertilizer formulations covering phosphorus, potassium, nitrogen, and calcium nutrition.

What are water-soluble fertilizers?
Water soluble fertilizers are fertilizers designed to dissolve in water and provide nutrients in a form suitable for application through fertigation or foliar spray, depending on the product.
Because these fertilizers can be applied through irrigation systems, they can be incorporated into nutrient management programs where controlled and convenient nutrient application is required.

Advantages of Water Soluble Fertilizers
Water soluble fertilizers can offer several practical benefits:
  • Easy preparation for application
  • Suitable for fertigation with compatible formulations
  • Useful for foliar nutrition where recommended
  • Convenient nutrient management
  • Availability of different NPK combinations
  • Flexibility in selecting nutrients according to crop stage
The actual application method and dosage should always follow the product label.

12:61:00 Mono Ammonium Phosphate
ULTRA-FERT Mono Ammonium Phosphate 12:61:00 is a highly water-soluble formulation containing nitrogen and phosphorus.
Phosphorus is particularly relevant to root development and reproductive stages of crops. This type of formulation can therefore be incorporated into crop nutrition programs where phosphorus demand is important.

00:52:34 Mono-Potassium Phosphate
ULTRA-FERT Mono-Potassium Phosphate 00:52:34 supplies phosphorus and potassium in a water-soluble formulation.
The combination makes it relevant to crop nutrition programs where both phosphorus and potassium are required. Potassium is an important nutrient for crop quality and reproductive development, while phosphorus has an important role in plant energy processes and root development.

00:00:50 Potassium Sulphate
ULTRA-FERT Potassium Sulphate 00:00:50 is a water-soluble potassium and sulphur fertilizer.
It contains potassium along with sulphur and can be incorporated into crop nutrition programs where these nutrients are required. Potassium nutrition is particularly important when crops enter demanding reproductive and quality-development stages.

13:00:45 Potassium Nitrate
ULTRA-FERT Potassium Nitrate 13:00:45 supplies both nitrogen and potassium.
This combination provides an option for crops requiring these two major nutrients. The formulation can be used as part of a nutrient management program according to crop requirements and recommended application rates.

Calcium Nitrate
Calcium nitrate formulations provide calcium and nitrate nitrogen. Urban Green Crop Science's brochure includes calcium nitrate-based products, including Calcium Nitrate Fortified with Magnesium.
Calcium is associated with plant structural development, while nitrogen supports plant growth. The combination can therefore be useful where both nutrients are required.

Why NPK Formulation Matters
NPK fertilizers combine nitrogen, phosphorus, and potassium in specific ratios. Different ratios are designed to address different nutritional requirements.
For example:
  • Higher nitrogen formulations may be considered when nitrogen nutrition is required.
  • Higher phosphorus formulations may be selected during stages where phosphorus is important.
  • Higher potassium formulations may be relevant during flowering, fruit development, and quality-focused crop stages.
  • Balanced formulations can be selected when multiple major nutrients are required.
The correct formulation should be selected based on crop requirements and professional agronomic recommendations.

Fertigation and Water Soluble Fertilizers
Fertigation involves supplying nutrients through an irrigation system. Water-soluble fertilizers can be convenient for this method because they are designed to dissolve in water when used according to product instructions.
However, compatibility with the irrigation system and other fertilizers should be considered. Incorrect mixing can lead to precipitation or reduced nutrient availability.

Water Soluble Fertilizers for Different Crops
Water-soluble fertilizers can be used across various agricultural and horticultural crops, depending on the formulation. Urban Green Crop Science's product information references applications across crops such as:
  • Grapes
  • Pomegranate
  • Banana
  • Cotton
  • Tomato
  • Onion
  • Sugarcane
  • Ginger
  • Turmeric
  • Watermelon
  • Floriculture
  • Protected cultivation
The appropriate product and application rate should be selected according to crop stage and nutritional requirement.

How to Select a Water Soluble Fertilizer?
Before choosing a WSF product, consider:
1. Crop requirement: Different crops have different nutritional requirements.
2. Growth stage: Nutrient demand can change between vegetative, flowering, and fruiting stages.
3. Nutrient ratio: Select the NPK or specialty nutrient formulation according to the desired nutrient supply.
4. Application method: Check whether the product is recommended for foliar spray, fertigation, or both.
5. Dosage: Follow the manufacturer's recommended dosage.
