What can happen if we grow only one crop in a row?
Continuous cropping is one of the traditional activities of our farmers. This is because most farmers have been cultivating sesame on the same land since ancient times and still cultivate sesame. There are some advantages to cultivating a single crop on the same land, but the disadvantages are many.
Immunity to germs
Continuous planting of the same crop on the same land makes it harder to control the annual pests and diseases. For example, let’s say you grow pepper every year. Absorbs are more likely to be resistant to pesticides, as they are treated with a regular spray. That’s why they suggest you try to grow crops. Another thing is that it is very easy to spread the disease when a plant is infected with a single crop because it is grown on a single crop.
Damage to agricultural lands
When a single crop is grown continuously in the same soil, some nutrients may be depleted over time. When the soil is malnourished, a lot of chemical fertilizers are added in addition to natural fertilizers. When chemical fertilizers increase, the soil becomes unhealthy and some of the soil becomes uncultivated. It also reduces soil fertility and resistance to soil erosion.
Excessive use of pesticides
Continuous cropping has been found to be more susceptible to infection. One pesticide after another is used to kill the germs. Doing so can be costly and suffer from the side effects of pesticides. Water-soluble and permeable pesticides can cause serious harm to marine life.
Feeding a lot of fertilizer
Continuous planting of a single crop depletes the soil of nutrients and damages the soil. So a lot of fertilizer has to be replenished, which is expensive and not good for the soil and the environment.
Water and air pollution
When cultivating a single crop in a row, use the usual annual pesticides and chemicals. Fertilizers are still used. This can lead to water and air pollution over the years. Nitrogen fertilizers decompose into nitrogen in the soil and move easily through the soil. These nitrates travel through the ground into the groundwater, which has been around for decades, causing groundwater pollution.
In our agriculture in Myanmar, soil is life. Without land, agriculture is not easy to cultivate and the existing land needs to be fertile and healthy. If you want to be a long-term farmer, you need to avoid growing a single crop on the same land. Instead, we respectfully suggest that you do crop rotation, pruning, and replanting.
