FREQUENTLY ASKED QUESTIONS

Click on each question to see the answer.

Why choose MKP 0-52-34 over other phosphorus fertilizers?

MKP 0-52-34 offers unique advantages for specific growing situations:

Key Benefits of MKP:
  • Zero nitrogen - prevents unwanted vegetative growth during flowering
  • High potassium (34%) - enhances fruit quality and plant health
  • 100% water-soluble - perfect for precision feeding
  • Low salt index - safer for sensitive crops
  • pH neutral in solution - won't acidify like MAP

MKP vs Other P Sources:

Fertilizer N-P-K Best Use
MKP 0-52-34 Late bloom, quality enhancement
MAP 11-52-0 Early growth, root development
DAP 18-46-0 High N needs, vegetative growth

Choose MKP when you need pure P-K nutrition without nitrogen, especially during flowering and fruiting stages where excess N can reduce quality.

How do I avoid leaf burn when using MKP as foliar spray?

MKP can cause foliar damage if not applied correctly. Follow these critical guidelines:

Temperature Management:

  • Morning (temps rising): Stop spraying when temperature reaches 84°F
  • Evening (temps falling): Don't start until temperature drops to 90°F
  • For pears: Reduce rate to 8 lbs/acre max when temps exceed 90°F

Application Best Practices:

  • Maintain 7+ days between applications
  • Never apply to stressed plants (drought, disease, pest pressure)
  • Use sufficient water volume - aim for 350 GPA for dilute sprays
  • Avoid excessive runoff or dripping
  • Test on a few plants first
  • Add a surfactant for better coverage

Concentration Guidelines:

  • Dilute spray: 3-5 lbs per 100 gallons (max 15 lbs/acre)
  • Concentrate spray: 5-10 lbs/acre in 15-150 gallons
  • Young/dwarf trees: Use lower rates to avoid over-spraying
Warning: Handgun application increases risk of leaf injury. Ensure proper calibration and avoid excessive application to any single area.
When should I use MKP in my growing program?

MKP timing is critical for maximum benefit:

Flowering Plants:

  • Pre-bloom: 1-2 weeks before flowering
  • During bloom: Throughout flowering period
  • Post-bloom: To support fruit/seed development

Fruiting Crops:

  • Fruit set: Immediately after pollination
  • Fruit development: Every 2-3 weeks
  • Pre-harvest: 2-4 weeks before harvest for quality

Specific Crop Examples:

  • Tomatoes: Start at first flower cluster, repeat every 2 weeks
  • Grapes: Pre-bloom, post-bloom, and 30 days before harvest
  • Strawberries: After first blooms, continue through season
  • Cannabis: Week 3 of flower through week 6-7
Pro Tip: MKP is especially valuable during late flowering/ripening when you want to enhance quality (sugars, flavors, colors) without promoting new vegetative growth.
Can I mix MKP with other fertilizers or pesticides?

MKP is generally compatible with most agricultural products, but follow these guidelines:

Compatible With:

  • Most water-soluble fertilizers (except calcium)
  • Micronutrient chelates (iron, zinc, manganese)
  • Most fungicides and insecticides
  • Growth regulators and biostimulants
  • Magnesium sulfate (Epsom salt)

NOT Compatible With:

  • ❌ Calcium fertilizers (forms precipitate)
  • ❌ High pH products (above 8.0)
  • ❌ Concentrated sulfuric acid
  • ❌ Some copper-based fungicides

Mixing Procedure:

  1. Fill tank with 50% of water needed
  2. Start agitation
  3. Add MKP and ensure complete dissolution
  4. Add other products one at a time
  5. Fill tank to final volume
Jar Test: Always perform a compatibility test by mixing small amounts in a jar before tank mixing. Look for precipitation, gel formation, or excessive heat.

We have been using this for several years to use in our fertigation system

We have been using this for several years to use in our fertigation system. Dissolves fairly well. Research the recommended water temperature for optimal dissolution.
