If you want to grow vegetables, but the soil is not good, we have a way to fix saline soil and acidic soil to become fertile soil ready for planting. Good technique from the book “ Easy to grow vegetables outside, can do every season “ through real experiments by Teacher Ketsirin Saengmanee
Especially soil problems that many people tend to encounter often, such as clay soil, sand soil, acid soil, saline soil, or even bagged soil that we buy to use. Try this method to solve saline soil, turn bad soil into soil ready for planting.
clay
Some soils are clay soils, especially in cities where paddy soil is often filled. The dense, clay texture can slow or halt the growth of the plant. How to improve clay to be airy and crumbly Better drainage and air Increase fertility, making it easy to root Chonchai. Add 2 kg of manure or compost and 2 kg of chopped coconut husks or coarse sand per 1 square meter plot.
sandy soil
Soil characteristics are high porosity, not water-absorbing, improve with organic matter that holds water well, such as manure, compost or earthworm manure at a ratio of 1-2 kg and coconut coir 1 kg per 1 square meter of plot. May use rice husk ash, sawdust or Dried leaves can be substituted for coconut husks. Mix well and ferment for 15 days to make the soil have better water holding capacity and higher nutrient content.
acid soil
Acidic soils or soils with a strong acidity The basic soil amendment is adding lime to reduce soil acidity, such as limestone, lime or calcined shells, marl, dolomite. Duration depends on soil acidity.
Soil with pH 3-4 , 1-1.5 kg of lime, 2 kg of raw rice husk and 2-3 kg of manure per 1 square meter plot, mix well. Sprinkle with bio-fermented water at a ratio of 20 ml (4 tablespoons) per 10 liters of water.
Soil with pH 4-5 , 1 kg of lime, 1 kg of rice husk and 2 kg of manure per 1 square meter plot, sprinkle with bio-fermented water at a ratio of 20 ml (4 tablespoons) per 10 liters of water.
During composting, mulch with straw or saran. Water 2 times a day. Biocompost every 7 days. Highly acidic soil takes 2-3 months, and less acidic soil takes 1 month.
saline soil
Soils with a large amount of soluble salts in soil solutions. until affecting the growth and productivity of plants You will notice a patch of salt. especially in the dry season Plants often show signs of late blight. stunted stem because the plants are dehydrated Toxicity from elemental sodium and chloride and nutrient imbalance The soil can be improved by nourishing with organic matter such as rice husk, manure, compost, green manure or using gypsum. together with manure and compost to reduce the salinity of the soil adjust the structure and increase the amount of nutrients Salt-tolerant crops that are suitable for soil salinity may be selected, such as asparagus, tomatoes, chives, cantaloupe melons, broccoli, kale. Drip irrigation It helps to control soil moisture, soil salinity and conserve water well. In addition, the soil should be mulched after planting to maintain moisture and prevent salt accumulation on the soil surface.

bag of soil
Some formula bags of soil Contains too much coconut flakes or any other organic matter. causing insufficient nutrients Improvement methods do the same as improving clay soil and composting. The bag soil is mixed with manure and chopped coconut husks, 1 part each, soaked with 1 tablespoon (5 ml) of bio-fermented water per 1 liter of water, and mix well. Cover the soil, put it in the shade, leave it for 15 days, or touch it and it’s not hot, it can be used to grow vegetables. Or compost bag soil with garden weeds, dry leaves or household food scraps. Mix well and water the bio-fermentation. When it’s crumbly, it will be planted next to vegetables.
Tips
- If you have a lot of space and want to grow vegetables as a trade. Soil samples should be collected to measure fertility. pH and physical characteristics as a guideline to improve the soil to be suitable for planted vegetables
- The fermented soil is dark in color. suitable humidity suitable for growing plants
- Even if the soil is improved to be fertile for growing vegetables, fertilizing is still required for the vegetables to thrive. and get quality products especially vegetables that are many years old It is necessary to increase the nutrients in the soil, whether it is organic fertilizers or chemical fertilizers, bio-fertilizers.
