How is crop rotation useful for farmers?
» Crop rotation is an important strategy for managing some diseases, weeds, and insect pests of vegetable crops. » Rotating crops also provides nutritional benefits to plants and maintains soil health. Rotating crops helps maintain or improve soil health and maintain or increase the productivity of the farm over time.
How does a plow work?
A plow (also spelled “plough”) is a farm tool with one or more heavy blades that breaks the soil and cuts a furrow (small ditch) for sowing seeds. An important piece of the plow is called a moldboard, which is a wedge formed by the curved part of a steel blade that turns the furrow.
What are two disadvantages of Agriculture?
Following are disadvantages;
- Lack of water resources – agriculture predominantly dependent on good monsoon.
- Paucity of Electricity.
- Low productivity of agri / horti crops coupled with lower per cent of A grade produces.
- No timely availability of seed/ seedlings, agro-chemicals, fertilizers etc.
What is the importance of agriculture to human?
Agriculture plays a significant role to both human and economy of a nation; that is to say, it is the backbone of a nation’s economy. In addition to providing food and raw material, it also provides employment opportunities to very large percentage of the population.

Agriculture plays an essential role in sustaining and driving the economy. It’s the backbone of everything that drives us. In addition to providing food and other raw materials, it also provides employment opportunities. Safe to say the importance of agriculture cannot be overstated.
How is agriculture important to the economy?

Why do few farmers use IPM?
IPM provides farmers a low-cost way to reduce the risk of losing their crop. IPM also allows them to buy fewer pesticides and reduced health risks to their employees. IPM also reduces the environmental and public health risks associated with the heavy use of pesticides.
Why do farmers deep plow?
The purpose of deep plowing is to modify the soil water retention characteristics over the long term. The theory is that this will stop the loss of topsoil, increase the organic content of soil and reduce runoff of fertilizer and pesticides into rivers.
What are the losses caused by weeds?
Weeds are harmful in many ways. The damages caused by them are as under: 1. Reduction in crop yield:- Weeds compete with crops for water, nutrients and light. Being hardy and vigorous in growth habit, they grow faster then crops and consume large amount of water and nutrients, thus causing heavy losses in yields.
How does intercropping reduce the need for herbicides?
Intercropping and cover cropping are practices that increase diversity in the cropping system and enhance the utilization of resources such as light, heat and water. These practices can also help to suppress weeds and increase the likelihood of being able to reduce herbicide use in the cropping system.
What are the benefits of agriculture?
- Higher crop productivity.
- Decreased use of water, fertilizer, and pesticides, which in turn keeps food prices down.
- Reduced impact on natural ecosystems.
- Less runoff of chemicals into rivers and groundwater.
- Increased worker safety.
What is crop rotation and why it is important?
Crop rotation is the practice of planting different crops sequentially on the same plot of land to improve soil health, optimize nutrients in the soil, and combat pest and weed pressure. For example, say a farmer has planted a field of corn.
How does tillage help control weeds?
In addition to reducing growing weeds, primary and secondary tillage can change the distribution of weed seed in the soil profile, which can influence germination and seedling establishment.
What is the importance of crop?
Importance of Crop Production Agronomic crops provide the food, feed grain, oil, and fiber for domestic consumption and are a major component of U.S. export trade. Horticultural plants — those grown specifically for human use — offer variety to human diets and enhance the living environment.
What is the difference between a cultivator and a plow?
A plow turns over the top layer of soil, burying what is on top. A cultivator gets rid of weeds in the crop. Different equipment for different jobs.
Why is plowing important?
Soil can become dense and compact. Plowing also makes it easier to plant. Plowing breaks up the blocky structure of the soil which can aid in drainage and root growth. Plowing fields can also turn organic matter into soil to increase decomposition and add nutrients from the organic matter to the soil.
