What would happen if one grows the same crop repeatedly in the same field?
If the same crop is grown continuously, the plant drains the same nutrients from the soil every year. This eventually leads to nutrient depletion and soil infertility.
What happens to farmland when we continue to plant the same crops?
If a farmer plants the exact same crop in the same place every year, as is common in conventional farming, she continually draws the same nutrients out of the soil. Pests and diseases happily make themselves a permanent home as their preferred food source is guaranteed.
Why is growing one crop in a row bad for soil fertility?
When a single crop is planted in the same place every year, the soil structure slowly deteriorates as the same nutrients are used time and time again. After a few years, the soil becomes unhealthy, drained of those specific nutrients.
Can land become infertile?
Soil fertility is essential for plant growth. Often, however, many people do not keep track of the condition of the soil they use. The results are evident in the increased land sizes that are becoming infertile. Over time, increased infertility, if not tackled, will lead to land being completely barren.
Why do farmers grow different crops in a field?
Farmers grow different crops in a field because different crops may vary in nutrient requirements. This ensures complete and uniform utilization of nutrients present in soil. It prevents soil depletion, increases soil fertility, reduces soil erosion and the need for fertilizers.
What happens to the soil in a field if crops are grown in it season after season without manuring?
The field becomes unfertile. It does not give any time to soil to replenish the nutrients. Thus the soil is unable to sustain any further healthy and good crop.
Does soil fertility decrease after crops are grown regularly in it?
Once the plants are grown in a field they use all the nutrients from the soil for their growth. Hence ,the fertility of the soil decreases after crops are grown regularly….
What are the advantages and disadvantages of crop rotation?
What is Crop Rotation?
- Advantages of Crop Rotation. Increases Soil Fertility. Increases Crop Yield. Increases Soil Nutrients. Reduces Soil Erosion.
- Disadvantages of Crop Rotation. It Involves Risk. Improper Implementation Can Cause Much More Harm Than Good. Obligatory Crop Diversification. Requires More Knowledge and Skills.
Why does soil become infertile?
As the acidity level of the soil rises, the amount of energy required by plants to absorb key nutrients increases, making it more difficult for the plants to absorb them. When soil is too acidic, plants cannot absorb the nutrients they need, thus rendering the soil infertile and unable to produce growth.
What happens if a soil becomes infertile?
Soil infertility implies lack of the qualities which enable it to provide nutrient elements and compounds in adequate amounts and in proper balance for the growth of specified plants. Infertile soils lacking in decomposing organic matter such as manure, will lack nutrients and binding qualities as well.
Why do you understand by mixed cropping?
Mixed cropping refers to a process of raising different crops in the same area at the time. Mixed cropping is a technique of sowing two or three crops on the same piece of soil, with one serving as the participate in national and the others as secondary crops.
What will happen if the crops are not looked after properly?
The nutrients and minerals in the soil will be exhausted. The soil will lose it’s fertility and it will no more be suitable to grow good quality crops. >>
