Dr. Peha CaP is a greening material that is mixed with vegetation substrates or imported soil and sprayed onto slopes for use. Features of Dr. Peha CaP: ■ Neutral material Since it is a neutral material, it can be safely applied even on slopes where neutral and acidic areas are mixed. There is no risk of alkalization from excessive application. ■ Deep soil neutralization and improvement Microorganisms break down Dr. Peha CaP, and the fine effective components travel through soil pores to exert neutralization effects deeper into the soil. ■ Response to strong acidity The calcium contained as a component is finely broken down by microorganisms and moves through the soil gaps to neutralize deeper areas. ■ Activation of microorganisms, promotion of granulation, and suppression of acidification The activation of diverse microorganisms in the soil promotes the granulation of soil volume and facilitates the leaching of sulfuric acid. Additionally, a diverse microbial community is established, which suppresses acidification through their antagonistic effects. *For more details, please refer to the PDF materials or feel free to contact us.

■Neutralizes acidic soil just by spreading By simply applying a diluted MELK solution to acidic slopes, the surface can be neutralized to a pH suitable for greening. ■Root extension into the underlying soil Neutralizing the surface makes it easier for roots to extend into the underlying soil, facilitating early integration with the substrate. ■Suppression of electrical conductivity During neutralization, the solubility of sulfate ions is reduced, which suppresses or lowers the increase in electrical conductivity. ■Difficult solubilization of alumina To prevent damage to roots, harmful alumina that leaches out is made less soluble. ■Greening possible within a few days Greening work can be carried out within a few days after application. ■Sustainability Residual components on the surface (such as calcium carbonate) neutralize acids that seep from the lower layers over the medium to long term. *For more details, please refer to the PDF document or feel free to contact us.*

• Soil improvement material

■ "Boston Farm II" is made from 100% recycled materials and is an environmentally friendly lightweight soil. ■ Certified by the Public Interest Incorporated Association for Rainwater Storage and Infiltration. ■ The wet density is very lightweight at "0.65 to 0.8." ■ It is an organic soil that contains 20% pruning branch compost. 【Features】 ■ 100% of the material is recycled. ■ The void ratio during compaction is over 30%, providing excellent water retention performance (comparable to single grain soil regeneration No. 4). ■ Wet density: 0.65 to 0.8, making it suitable for use as fill material on top of resin storage tanks. ■ Contains 20% pruning branch compost as organic soil. *For more details, please refer to the related link page or feel free to contact us.

• Other park materials

Here is an example of slope greening using "Dr. Peha liquid agent." On a river embankment, a 12-fold diluted solution (2-3L/m2) was sprayed on a slope with a pH of 9.0 to 10. After spraying, it stabilized at a pH of 7.5 to 8.0. 【Case Overview】 ■ Neutralized to below pH 8.0 ■ Laid down wild grass ■ Roots are distributed in the neutralization treatment layer. The carbon dioxide released by the growing roots expands the neutral range. *For more details, please refer to the PDF document or feel free to contact us.

"Dr. Peha Liquid Agent" is a type of neutralizing agent that is diluted with water and sprayed. ■ It is particularly suitable for greening projects on alkaline surfaces where mechanical mixing of neutralizing agents is not possible. ■ It is also suitable for neutralization treatment to restore tree vigor when planted in alkaline soil, as well as for pH control in sports turf. 【Features】 ■ It is a safe product with no legal regulations regarding transportation and storage. ■ By making the salts generated from the neutralization reaction less soluble, it results in a small increase in electrical conductivity, making it an optimal neutralizing agent for vegetation. ■ It is economical as it only requires dilution and spraying. *For more details, please refer to the PDF materials or feel free to contact us. (Catalog p.2, p.6–p.9 are relevant.)

• Soil improvement material

"Dr. Peha Landscaping" is a neutralizing agent for landscaping, gardening, and agriculture. ■ It insolubilizes the salts generated by the neutralization reaction, suppressing the increase in electrical conductivity. ■ Neutralization tests are conducted free of charge. Please send approximately 1 kg from one location to our company. * For more details, please refer to the PDF materials or feel free to contact us. (See general catalog p.2, p.4–p.5 for details.)
