Advantages of creating fields without plowing

Advantages and disadvantages of plowing

Plowing is taken for granted in farming, but it is a very difficult task. You must be working hard in farming, thinking that the more you cultivate, the better.
However, not just cultivating is good. Plowing has advantages and disadvantages.

The benefits of plowing

By loosening solid soil and improving drainage and aeration, it makes it easier for vegetables to take root and activates aerobic bacteria. The active activity of aerobic bacteria promotes the decomposition of organic matter, making it easier for nutrients to escape into the soil.

By mixing compost and fertilizer into the soil, nutrients can be efficiently absorbed through the orchid roots.

Weeds are mixed with the soil and decompose to create a weed-free state.

By loosening it smoothly, you will be able to shape it into any shape, such as raising the ridges, and it will be easier to sow and plant.

“Disadvantages” of the plowing

Immediately after plowing, it becomes loose, but the root structure of the plant also flattens, so the soil becomes more compact over time.

By mixing air into the soil to prevent weeds from growing on the soil surface, the soil dries out. In Japan there is less of a problem, where it rains heavily and is humid, but it can lead to desertification in arid regions.

Soil organic matter is decomposed and nutrients are temporarily abundant in the soil, but the organic matter is dissipated for a while leading to a decrease in the ability to hold compost and water.

By making it smoother, soil and nutrients can easily flow in the rain.

Land plowing puts the load on the ground

When barefoot, the burden on the earth is enormous.

By plowing, an environment where vegetables can easily grow is created, and vegetable growth is temporarily promoted. But in return, you must also understand that the soil is more or less overloaded. If the burden increases, the soil hardness will decrease and vegetables will be difficult to grow.
However, some work is required for tilling and loosening the soil. Let’s think about the balance of nature so that this load does not become too large.

Why trees grow naturally without tilling

The fallen leaves are able to decompose and ferment by microorganisms, causing the soil to loosen

For some tips on how to create a field without cultivation, let’s first look at natural plants.
The trees in the forest and the weeds in the garden all grow well without plowing. It’s easy to think that the soil will be hard if you don’t nurture it, but especially the soil in the forest is very spongy and soft. It is also very nutritious. It is thought that the following three functions are mainly related.

1) Root work

By creating an acid called root acid from the root tip, the plant can dig even in difficult places. Even after withering, the part of the roots that lie there becomes a tunnel and becomes a passageway for air and water. This strength and depth of dig varies depending on the plant, and it can be said that weeds growing even on hard soil have this strength. Also, the myriad of roots make the structure soft like a sponge but difficult to tighten.

2) Function of “Fushoku”

A substance called “growing rotten plants” is produced by soil organisms such as microorganisms, waterworms and bugs that decompose and re-synthesize substances called organic matter such as dead grass, fallen leaves, dead organisms and feces. The piled up leaves may turn black, and this black is the color of rot.
As the amount of rot increases, the soil becomes dumpling-like seeds surrounding the portion. This state in which the number of dumplings is increased is called the synthetic structure. The surface of these particles is positively charged and the particles repel each other, making it easier for an air layer to form between them. Maintaining this synthetic structure makes the soil more porous. The rotting plant also acts as a reservoir for nutrients, so the proliferation of this rotting plant in the soil makes it easier for nutrients to be stored.

3) The function of soil organisms

As soil organisms move through the soil, there are countless pathways and the soil becomes porous. Mizumizu’s work is especially important. While eating organic matter, Mizumizu produces feces, which are believed to be structurally similar to rotten manure and very rich in nutrients.

How to farm without plowing

Weed compost is in the process of decomposition. Rich

By mimicking the soft and nourishing mechanisms of natural forests without plowing, you can recreate a field without plowing. I will explain how to make and take care of the soil for that purpose.

1) Create substrate to increase soil rot quality

The first point is to increase soil rot. In the natural world, it takes time to accumulate rot in the soil, act as a repository of nutrients and also function to keep it fluffy. To increase the amount of this substance in the soil, mix foliar mold and weed compost into the soil. In order for vegetables to grow well, the soil is loose and nutrient-rich requires a layer of soil about 40 cm from the ground, so mix well around that layer. Since it is 40 cm from the surface of the bed when finally erected, the actual plowing depth is about 20 cm.
Please refer to the following for soil preparation materials and quantities. From the second time onwards decrease gradually while monitoring the vegetable growth. Plant ash is added as a mineral supplement.

Per square meter
○ Organic manure (organic manure like cow manure is fine) 20l
○ Leaf land: 20l
○ Plant ash: 3 handfuls

2) Care points to maintain a soft and nourishing state

Plowing by itself is unavoidable as long as you are creating a field, so it is important to cultivate it in a way that does not consume too much and take care of the soil so that it does not consume too much. After plowing, we will pay attention to avoidance and be aware of the four disadvantages of plowing.

There are two main methods. One is to cultivate the grass while leaving the weeds growing during the growth of vegetables, letting the grass to loosen the soil, avoiding soil clipping. This also leads to the supply of organic matter to the soil. Note, however, that there are certain types of weeds that should not be uprooted. Please see the “link” for details on lawn mowing.
The second is to mix a large amount of material into the soil to prevent soil from hardening, especially in hard soil areas. For this, mold, rice husk charcoal, compost, etc. are effective.

To prevent the soil from drying out, avoid direct sunlight or wind. For that purpose, a method called coating is effective. In particular, mulching weeds and fallen leaves will also lead to the supply of organic matter. For more information on weeds and fallen leaves, see the “” article.

By adding compost to the soil, spreading weeds and deciduous leaf mulch, and mowing grass with leftover roots, it is possible to prevent the loss of organic matter in the soil. Mechanics can be easily done at home, invite you to consult.

First, the best practice is to cover the soil so that the soil is not directly exposed to rain. In terms of nutrient release, increasing the amount of soil rot increases the fertilization capacity. Since rot is a substance formed by the decomposition and re-synthesis of fallen leaves and weeds by microorganisms, it can be supplemented by covering the fallen leaves and weed mulch or by adding rotten manure and weeds to the soil. .

Gradually decrease plowing depth and area

Plow only the ridges and leave the sections intact. Especially in winter, weed growth is weak, so if not, the soil in the path will not harden and drain better.

While making and maintaining this soil type, we will gradually reduce the area and depth of cultivation. At first, only cultivate the top part of the ridge that was set up once, and don’t cultivate the spiritual path. The walkway is an easy place to roll, but if you leave weeds and fallen leaves behind or leave some weeds un-cut so that the soil won’t be as bare as possible, the roots will go on. . Does not become too stiff and the drainage capacity does not deteriorate.

Also, if you don’t plow, vegetables like radishes won’t be able to grow. Easy thought, but not so. You should try plugging the stick in the ground to see the softness of the layer.

By continuing such soil preparation and maintenance, the soil will be cultivated and fully grown without the need for tilling or composting. However, it takes at least 4-5 years to fully plant. In the meantime, let us continue to create fields that do not burden the soil or ourselves.
