What are the advantages of sowing seeds by using seed drill over that done by hand?

Short Answer

Expert verified

Answer: Some advantages of using a seed drill for sowing seeds include: uniform depth and spacing, higher efficiency and speed, reduced seed wastage, improved germination rates, reduced soil erosion, and enhanced weed control.

Step by step solution

Advantage 1: Uniform Depth and Spacing

Using a seed drill ensures that the seeds are sown at a uniform depth and spacing. This is beneficial for the growth of the plants, as it allows for equal distribution of water, sunlight, and nutrients. On the other hand, when sowing seeds by hand, it is difficult to maintain uniform depth and spacing, which could lead to unhealthy or stunted growth of the plants.

Advantage 2: Higher Efficiency and Speed

Seed drills are designed to be more efficient and faster than sowing seeds by hand. They can cover a large area in a short amount of time, reducing the labor and time required for sowing seeds. This can potentially lead to increased productivity and profitability for farmers.

Advantage 3: Reduced Seed Wastage

Seed drills accurately distribute seeds in the desired area, reducing the chances of seed wastage. Manual sowing, on the other hand, may result in an increased quantity of seeds being used due to inaccurate placement or uneven distribution. By reducing seed wastage, farmers can save money on seeds and resources.

Advantage 4: Improved Germination Rates

When seeds are sown at a uniform depth and spacing with a seed drill, they have a greater chance of germinating properly. Inadequate planting depth, which is more common when sowing by hand, can lead to decreased germination rates, affecting the overall crop yield.

Advantage 5: Reduced Soil Erosion

Seed drills can create small trenches for seeds to be placed in, providing some protection against soil erosion caused by wind or water. In comparison, seeds that are sown by hand are more likely to be exposed on the soil surface, making them more susceptible to being washed or blown away.

Advantage 6: Enhanced Weed Control

By planting seeds at a uniform depth, seed drills provide an environment that supports the growth of the desired crop while creating a competitive environment for weeds. The even distribution of the seeds means that less space is available for weeds to grow and the crop plants can outcompete them. When sowing by hand, this distribution is not guaranteed, so weed populations have more opportunities to take over. In conclusion, using a seed drill for sowing seeds provides numerous advantages over sowing by hand. These advantages include uniform depth and spacing, increased efficiency, reduced seed wastage, improved germination rates, reduced soil erosion, and enhanced weed control.
