Secrets to mixing soil to grow clean vegetables on the terrace

1. What is clean, nutritious soil?

Clean soil is soil that does not contain heavy metals, pathogens, pests, chemical fertilizers or pesticide residues.

Clean soil suitable for growing clean vegetables at home is the type of soil that contains micronutrients, trace elements, and organic substances that help vegetables grow.

To recognize clean, nutritious soil, after a period of cultivation, there are many worms under the soil layer; this proves that the soil does not contain chemicals, which is beneficial for growing clean vegetables.

2. How to mix soil for growing vegetables

This is a very important step, directly determining the growth and development of plants.

To grow vegetables on balconies and terraces, there are many types of soil for growing vegetables such as: sandy soil, loam soil, garden soil or alluvial soil.

Preparation:Plastic tray, foam box:You should use a plastic tray with a smart mesh layer to drain water and prevent waterlogging for vegetables best.

1. Land:Alluvial soil or soil substrate treated with pathogens; can use prepackaged tribat nutrient soil available at stores, add sawdust, coconut fiber or rice husk ash
3. Fertilizer:Organic fertilizers should be used to provide additional nutrients. Green manure, decomposed cow manure, vermicompost, microbial fertilizers, etc. can be used.
5. After preparing all the tools, proceed to mix the soil: Different plants have different characteristics and require different mixing ratios; for leafy vegetables, mix in the following ratio: 5 parts base soil + 3 parts foaming medium + 2 parts fertilizer... For vegetables to grow best when planted on trays or pots, the soil thickness should be 10-13 cm.
7. Note: If using soil from fields or construction sites, it is necessary to dry and crush it, and treat it with lime powder before mixing to eliminate pathogens and weeds;
9. After mixing, level the soil surface, press lightly, paying attention to the corners of the pot.
11. 3. How to improve soil

After each crop, the soil nutrients gradually dry up and become hard, so it is necessary to supplement nutrients and increase soil porosity.Soil improvement has many benefits such as: Providing nutrients for plants to grow faster; helping plants resist pests and diseases, increasing germination ability, increasing productivity; ensuring product quality...

To improve vegetable growing soil, you can use one of the three following measures:

-Use organic fertilizers:DIf the soil is degraded, use treated cow manure; this type of manure helps the soil become loose and rich in nutrients.Mix in the following ratio: 1 bag of cow manure 10dm3 + 1 bag of tribat soil 10dm3 can be used for about 5 large vegetable pots, 8 small pots, 5 foam boxes.

- Use biological fertilizers:Microbial fertilizer does not heat up the soil, so it should be applied in proportion to stimulate the growth of plant roots; this type of fertilizer is very good for plants.Mixing ratio: 1 bag of 10dm3 biofertilizer + 1 bag of tribat for 9 large vegetable pots, 15 small pots and 10 foam boxes.

- Using worm castings:This type of fertilizer will destroy organic matter remaining during the planting and harvesting process; vermicompost is rich in nutrients so when planting trees, you do not need to add any other type of fertilizer...Mixing ratio: 1 bag of 10kg worm castings + 1 bag of tribat soil can be used for 10 - 12 large plastic pots, 15 small pots, 10 foam boxes...
