Let's grow brinjal easily Soil - Well-drained, fine-grained soil is suitable for brinjal cultivation. It is best to maintain the soil pH between 5.5 - 5.8. Climatic requirements - brinjal can be grown in areas with good sunlight, from sea level to an altitude of about 1300 meters. Seed requirement - About 350 grams per hectare. Nursery Management - Beds of 3 meters by 1 meter, arranged to receive the best sunlight, are suitable. The beds should be seeded. Add soil and manure in a 1:1 ratio. The seeds should be placed in rows with a spacing of 6 inches. Land preparation - Turn and level the land with a hoe or tractor. Planting - Plant the seedlings about 25-30 days old in prepared beds, one seedling per hole. Spacing - 90 cm x 60 cm. Watering - In dry areas, brinjal can also be cultivated with rainwater. Watering should be done to obtain a successful harvest and maintain it as a profitable crop. It is important to water the soil well during dry periods without allowing it...
Soil Degradation
Soil degradation can be termed as soil degradation due to erosion or reduction in crop productivity due to unknown agro-industrial practices and various human activities.
Causes of soil degradation,
- Hardening of the soil.
- Acidic or alkaline soil.
- Soil erosion.
Soil compaction is when the amount of space between the soil is reduced and the soil particles are pressed together.
Causes of soil compaction
- Moving heavy machinery over a soil surface.
- Workers walk frequently.
- Plowing in the same field for a long time
Adverse effects of soil hardness.
- Depletion of soil space interferes with plant roots and microbial respiration.
- The growth of plant roots is inhibited.
- Inhibition of microorganism growth.
- The ability to digest organic matter is reduced and the release of plant nutrients to the soil is minimized.
- Absorption of water into the soil is minimized.
- Soil drainage is poor.
- Land preparation is difficult.
Soil erosion,
- Soil erosion is the separation of soil, soil aggregates or particles from the soil body in a certain location and drifts to another location and deposits.
- Three stages of the erosion process can be identified,
- Separation of soil particles and aggregates from the soil body
- Drifting of detached soil aggregates and soil particles to another station.
- Deposition of soil fragments that have been blown away in another place
Soil conditioners
The factors that cause soil erosion are called soil erosion agents.
- Rain water
- Fast wind
- Sea waves and river waves
- Activities of humans and animals
Adverse effects of soil erosion,
- Decreasing the thickness of the soil layer suitable for plant growth.
- Plants suffer from nutrient deficiencies and stunt growth.
- The soil around the root system is washed away, causing the trees to fall.
- The value of agricultural land decreases.
- As the removed soil gets deposited in the reservoirs, it accumulates and causes flooding.
Reducing soil erosion
- There are two ways to mitigate soil erosion.
- Minimizing the segregation of soil particles
- Applying strategies to minimize the transport of soil particles and keep them in the soil.
Methods that can be used to reduce the separation of soil particles.
- Preventing raindrops from falling rapidly on the soil.
- Cultivation of quick cover crops.
- Cultivation of cover crops.
- Mulching the soil.
- Removal of aerial parts only in weed control.
- Preventing the separation of soil particles by using suitable land preparation methods.
Things that can be done to reduce soil transport and keep it in the soil
- Increasing infiltration of water into the soil.
- Cultivation of soil regeneration crops.
- Improving soil structure.
- Adding organic matter to the soil.
- Reducing the speed of water flowing over the soil surface.
- Contour plowing.
- Cultivation according to contour lines.
- Soiling on contour lines.
- Application of contour gutters.
- Application of contour stones.
- Dual application.
- Minimize erosion in drainage ditches that remove excess water from cropland.
