The soil on slopes and other areas targeted for greening projects often lacks nutrients and soil bacteria, making it unsuitable for plant growth, as it is not "rich soil." In particular, in the case of cooperative soils, necessary bases in the soil can be leached away by acids, leading to deficiencies, and the number of effective soil bacteria drastically decreases. pH Balance S contains organic materials such as polysaccharides and proteins, which promote the explosive growth of soil bacteria. The relationship between soil and soil bacteria is essential for plant growth and "soil creation," as processes like soil aggregation, nutrient supply, and organic matter supply are all functions of the soil.

The "pH Balance A Liquid Agent" is a material designed to promote the recovery of deteriorated tree vigor by neutralizing and improving the surface layer of already planted alkaline soil. When applied, it neutralizes the pH of the top 3-5 cm of the soil, allowing previously insoluble nutrients to dissolve and be utilized by plants, resulting in a rapid recovery of tree vigor. Even for tall trees, significant effects can be achieved since the nutrient roots are largely distributed near the surface. 【Features】 - Neutralizes and corrects alkaline soil, which is a major cause of tree vigor deterioration and dieback. - Can be applied directly to ground cover plants and lawns. *Please lightly rinse off any liquid agent that has adhered to the leaves with clean water after application.

"pH Balance A" is a pH correction material developed to green alkaline soils caused by cement-based solidifiers. It maximizes the buffering capacity of the greening substrate material, minimizing the effects of alkalinity and establishing a healthy greening base layer. The buffering capacity refers to the function that attempts to maintain pH against fluctuating factors (such as acid rain), and greening substrate materials rich in organic matter possess a high buffering capacity. When mixed with "pH Balance A," the buffering capacity of the greening substrate material exhibits a synergistic effect, suppressing fluctuations in pH values. 【Features】 ○ Easy to handle ○ High safety ○ Zero fish toxicity ○ High pH maintenance function ○ Does not increase electrical conductivity For more details, please contact us or download the catalog.

The alkaline soil regeneration material "Dr.pH" is effective for all types of alkaline soil. Strongly alkaline soil is treated as "industrial waste," leading to high disposal costs and developing into serious environmental issues such as alkaline contamination. In response to this problem, we developed this product with the aim of regenerating alkaline contaminated soil for greening purposes. 【Five Distinctive Features of Dr.pH】 - Regenerates soil for greening and reduces the amount of leftover soil - Reduces costs by 50% through neutralization and reuse - Plants can be installed 10 to 24 hours after application - Composed of materials that are harmless to humans and the environment - Easy to mix with soil *For more details, please contact us or download the catalog.

"Dr. Peha for Landscaping" is an alkaline soil neutralizer that neutralizes soil alkalization, which can cause poor growth. Here, we will introduce the target pH values for neutralization and improvements to the planting base that should be used in conjunction with neutralization treatment. Essential nutrients such as phosphorus and potassium become less soluble at pH 7.5 to 8.5. Additionally, trace elements like iron and manganese hardly dissolve when the pH exceeds 8.0. When the soil becomes alkaline in this way, plants cannot absorb nutrients, leading to poor growth, which is why it is necessary to neutralize the soil. [Target pH Values for Neutralization] - Generally, below pH 8.0 - Our research indicates that growth often varies significantly around pH 7.5, so it is advisable to set a target value of pH 7.5 or lower. *For more details, please refer to the PDF document or feel free to contact us.

"Dr. Peha Liquid" is an alkaline soil neutralizer used for greening alkaline slopes. Here, we will introduce examples of slope greening projects. 【Project Examples】 ■ Location: River embankment ■ Challenge: Neutralize to pH 8.0 or below ■ Procedure - Spray a 12-fold diluted solution (2-3L/m2) onto slopes with a pH of 9.0 to 10 - After spraying, stabilize at pH 7.5 to 8.0 - Apply wild grass (January to March 2013) - Three months after applying the wild grass, the roots distribute into the neutralization treatment layer, and the roots extend, expanding the neutral range due to the carbon dioxide released. *For more details, please refer to the PDF document or feel free to contact us.

"Dr. Peha Liquid" is an alkaline soil neutralizer for greening alkaline slopes. Here, we will introduce the recovery of tree vigor in existing green spaces planted in alkaline soil. 【Surprisingly Common Alkaline Soil】 ■ In construction sites for buildings such as apartments, it is common to carry out ground improvement work using solidifying agents like cement for seismic reinforcement. ■ As a result of this, the ground can become alkaline, and reused soil may also turn into alkaline soil. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the features of the alkaline soil neutralizer "Dr. pH" and the necessity of neutralization testing. The neutralization reaction generates many salts in the soil. As a result, the electrical conductivity of the soil increases, making it impossible for plants to grow. The Dr. pH series softens salts and suppresses the increase in electrical conductivity. Neutralized soil can be used in agriculture and landscaping. (Excluding civil engineering powder). 【Features】 ■ Softens salts generated by the neutralization reaction ■ Since it suppresses the increase in electrical conductivity, neutralized soil can be used in agriculture and landscaping *For more details, please refer to the PDF document or feel free to contact us.
