Groton Npk 20:10:10 (Liquid Fertilizer) | 1L (MOQ:3)

The 1L bottle is a concentrate, and the MOQ:3 targets farmers, landscapers, and serious gardeners who need to address specific plant growth stages or deficiencies.

NPK Ratio Breakdown & Agronomic Significance of Groton Npk 20:10:10 (Liquid Fertilizer) | 1L (MOQ:3):

• Nitrogen (N) – 20%: This is the key component. It drives the rapid development of leaves, stems, and shoots, promoting a dense, lush, and dark green plant canopy. It is essential for chlorophyll production and overall plant vigor.

• Phosphorus (P₂O₅) – 10%: Provides a foundational level for root development and energy transfer. While not the focus, it ensures the plant has the structural and energetic support to sustain the rapid growth stimulated by the high nitrogen.

• Potassium (K₂O) – 10%: Offers baseline support for plant vitality, water regulation, and some disease resistance. It helps maintain a balance while the plant focuses its energy on vegetative growth.

Why a High-Nitrogen 20:10:10 Ratio is Used:
This formulation is a “lawn and leaf booster.” It is strategically used when the primary goal is to build plant mass quickly, correct nitrogen deficiencies (characterized by pale green or yellowing leaves), and prioritize foliage over flowers or fruits.

Key Features & Benefits:

1. Rapid Greening Effect: Quickly corrects nitrogen deficiency and restores a deep green color to foliage.
2. Stimulates Vegetative Growth: Ideal for encouraging dense, lush lawns, leafy vegetables, and establishing young plants.
3. Quick-Acting Formula: As a water-soluble liquid, nutrients are immediately available for plant uptake.
4. Versatile Application: Suitable for soil drench, fertigation, and foliar spraying.

Application Guidelines:

• Shake Well: Thoroughly shake the bottle before use.

• Dilution is Critical: This is a highly concentrated formula, especially in nitrogen. A typical dilution is 3-5 ml per liter of water, but ALWAYS FOLLOW THE SPECIFIC INSTRUCTIONS ON THE PRODUCT LABEL to avoid fertilizer burn.

• Application Methods:

  • Soil Drench: Water into the root zone.

  • Foliar Spray: Apply directly to leaves for a very quick greening effect.

• Frequency: Applied every 2-4 weeks during the active growing season.

Ideal Use Cases & Target Crops:

• Best For:

  • Lawn Care: For greening up and thickening turfgrass in the spring and early summer.

  • Leafy Vegetables: To boost yields of crops like spinach, lettuce, cabbage, and kale.

  • Young Plants & Transplants: To encourage rapid establishment and vegetative growth.

  • Ornamental Foliage Plants: To maintain lush, green leaves (e.g., in ferns, hostas).

• Crops to Use With Caution:

  • Flowering or Fruiting Plants: The high nitrogen can promote excessive leafy growth at the expense of flowers and fruits. It is best avoided during the flowering/fruiting stage for tomatoes, peppers, etc.
