Chapter 1: Why Make Ridges? Its Four Amazing Effects Ridge making refers to the process of digging up flat ground and piling up soil in a straight or curved shape with a certain width and height. Let's delve deeper into why this seemingly troublesome extra step is absolutely essential for cultivation. 1. Ensuring excellent drainage and aeration One of the biggest reasons why many vegetables wither and die is root rot. Japanese soil, in particular, receives a lot of rain, and if left flat, water accumulates and there is insufficient oxygen in the soil. By piling up the soil to make ridges, excess water flows into the grooves between the ridges, ensuring that the inside of the ridges always has adequate moisture and "air passages" necessary for plant roots to breathe. 2. Maintaining a "fluffy environment" where roots can easily grow The area where ridges are made is an area where people will never set foot. This prevents the fluffy soil, which has been tilled and aerated, from being compacted by human weight. In soft soil, plant roots can grow vigorously in all directions without stress, and efficiently absorb nutrients from the soil. 3. Raising soil temperature promotes growth Compared to flat ground, raised ridges have a significantly larger surface area that receives sunlight. This makes it easier for the soil temperature to rise, especially during chilly periods such as early spring. Plants grow dramatically better in the early stages when their feet (roots) are warm, so creating ridges is essential for getting off to a good start. 4. Dramatically improves the efficiency of management and harvesting The furrows between ridges become pathways for workers to walk through. Since it becomes clear where to walk, there is no need to worry about accidentally stepping on valuable crops. Also, because the ground is higher, bending down becomes a little easier, making daily tasks such as watering, weeding, and harvesting much smoother. Chapter 2: Steps to Mastering Ridge Creation in the Field Now, let's explain the specific steps for creating beautiful and functional ridges using the ground in your field or garden. From preparation to finishing, each step is filled with the attention to detail of a professional. Step 1: Preliminary Soil Planning and Measurement First, decide on the size of the ridge you want to create. For common vegetables (tomatoes, eggplants, cucumbers, etc.), the basic golden ratio is "ridge width: approximately 70cm to 80cm" and "height: approximately 10cm to 15cm". Point: Place poles (supports) at the ends of the ridge and stretch a string (such as a tack line) between them. By using this string as a guide, even beginners can create surprisingly straight and beautiful ridges. Step 2: Scooping Soil from the Pathways (Between the Rows) to the Center Using a hoe or shovel, gather the soil from the outside of the stretched string (the part that will become the path) and place it on the inside of the string (the part that will become the ridge). Tip: At this stage, instead of just piling up the soil, break up the clumps of soil into smaller pieces with the back of a hoe as you go, which will make it easier for roots to grow later. Step 3: Level the surface (using a rake) Carefully level the top surface of the piled-up soil using a rake or the flat side of a hoe. If this area is uneven, water will accumulate in certain places when it rains, causing uneven growth. Tip: For the sides of the ridge (sloping parts), lightly tap and compact the soil with the back of a hoe. This is called "mud tamping," and it is an important technique to prevent the ridge from collapsing and losing its shape when it rains. Step 4: Coat with mulch sheet to finish Cover the surface of the ridge with an agricultural plastic sheet called "mulch." Secure the sheet by firmly covering the bottom edge of the ridge with soil so that it does not get blown away by the wind. Black mulch: Ideal when you want to completely suppress weeds. Transparent mulch: Effective when you want to raise the soil temperature to the maximum in early spring. Silver mulch: Effective when you want to keep away pests such as aphids that dislike light reflection. Chapter 3: Ideas for creating ridges with "Tobeban Mini" for use in small spaces "I understand that creating ridges is important, but I live on a balcony in an apartment building and don't have a large area of ​​soil..." Don't worry if that's what you're thinking. This is where the spirit of "Tobeban Mini" comes in, which condenses the benefits of ridges into an extremely compact form. Even in a limited space, you can recreate the same environment as ridges with a little ingenuity. Idea 1: "Mountain-shaped cultivation" to recreate mini ridges in a planter Instead of putting soil flat in a typical rectangular planter, this technique involves deliberately piling the soil in a "mountain shape," making the center higher and the ends lower.
