Actical P(soil amelioration)
Effects from use
- Adjust pH of soil to improve soil granulation generated from acid soil as well as Ca, Mg absorption hampering cause.
- Increase amount of useful microorganism of soil to advance moisture retention and permeability to create habitat for useful microorganism.
- Improve uprooting and survival characteristic while strengthening leaf and stem, where fruit size grows and sugar content and coloring improves to contribute quality of product and increase crop yields.
- Smoothen the physiological function by neutralizing organic acid such as a nitrous acid generated from un-fermented compost.
- Damage prevention of plant height, prevention of falling of fruit, flacherie, and acid rain.
- When injected into soil, and absorbs adequate amount of moisture, exothermic reaction occurs to disinfect harmful bacteria from soil
Feature and lime fertilizer comparison
Division | Actical P | Lime Fertilizer |
---|---|---|
Amount of Use (per 0.245 acre) |
2kg * 2 packs = 4kg (granular 1~4mm) |
20kg * 15 packs = 300kg (granular 2~5mm) |
Projected cost | 2packs * 20,000 won = 40,000 won | 15packs * 4,500 won = 67,500 won |
Advantage and disadvantage | - Reduce labor through small packing - Simple fertilization and fast soil improvement - Increase calcium absorption through high ionization - Alkaline over 60% |
- Overuse, excessive labor - Phenomenon of hardening soil - Calcium absorption decrease due to low ionization - Alkaline over 40% |
Deficiency Symptom per Crop
Crop | Calcium deficiency symptoms | Crop | Calcium deficiency symtpom |
---|---|---|---|
apple | Kow-tow, Water core, Fruit necrosis | grape | Berry shattering, Stem blight, Coloring defect |
tangerine | Decomposition, Coloring defect, Lowering of sugar content | pear | Wild pear, Preharvest drop, Sponge effect |
tomatoe | Anomaly, Blossom-end-rot, Gray mold | cucumber | Damping-off, Clubbed effect, Powder mildew |
oriental melon, water-melon, melon | Watered fruit, Puffy fruit | strawberry | Lowering of sugar content, Weakened hardness, Defect in storage, Soft rot |
welsh onion, onion, garlic | Soft rot, Bad condition of growth and development, Dried leaf tip | ginseng | Weight loss, Root knot nematode |
grass | Rotting root, Brown patch | flower | Defect in freshness maintenance, Coloring defect, Powder mildew |
Method of Use and Precaution
- Method of use: Do a fertilize process of Actical P 1 package (2kg) to soil 495~660m2 (0.122-0.163 acre). (When doing a fertilization process, mixing dirt and manure to spray is convenient)
※ Caution : Wear a mask and glove as highly concentrated calcium generates high temperature of heat when contacted with moisture, and clean the powder when it enters your eyes.
