Who are called farmers?
A farmer (also called an agriculturer) is a person engaged in agriculture, raising living organisms for food or raw materials. The term usually applies to people who do some combination of raising field crops, orchards, vineyards, poultry, or other livestock.
Who is farmers friend and why?
Earthworms are said to be always the friend of farmers. The reason is that earthworm increases the fertility of soil by increasing the amount of air and water that gets into the soil, facilitating aeration and increasing drainage.
What do farmers use to till the field?
Reduced tillage leaves between 15 and 30% crop residue cover on the soil or 500 to 1000 pounds per acre (560 to 1100 kg/ha) of small grain residue during the critical erosion period. This may involve the use of a chisel plow, field cultivators, or other implements.
Why is tilling soil bad?
The downside of tilling is that it destroys the natural soil structure, which makes soil more prone to compaction. By exposing a greater surface area to air and sunlight, tilling reduces soil’s moisture-retaining ability and causes a hard crust to form on the soil surface.
How do you till a field?
Tilling involves turning over the first 6 – 10 inches of soil before planting new crops. This practice works surface crop residues, animal manure and weeds deep into the field, blending it into the soil. It also aerates and warms the soil.
Why do farmers turn the soil in their fields Class 7?
Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Fertilizers are simply plant nutrients applied to agricultural fields to supplement required elements found naturally in the soil.
How do farmers protect their crops?
The best ways to protect crop damage are by incorporating integrated pest and insect management. Spraying insecticides, pesticides help to minimize the crop damage by controlling the insects and other pests.
How do farmers replace nutrients in soil?
Crop rotation is a technique of planting different crops in the same field, but during different times. This helps soil because some plants take nutrients from the soil while others add nutrients. Changing, or rotating, crops keep the land fertile because not all of the same nutrients are being used with each crop.
What fertilizer do farmers use?
Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain “micronutrients,” such as zinc and other metals, that are necessary for plant growth.
Which country is the largest producer of fertilizers?
Russian Federation is the top country by NPK fertilizers production in the world. As of 2019, NPK fertilizers production in Russian Federation was 7.57 million tonnes that accounts for 30.31% of the world’s NPK fertilizers production.
What is the most common fertilizer?
The most widely used solid inorganic fertilizers are urea, diammonium phosphate and potassium chloride. Solid fertilizer is typically granulated or powdered. Often solids are available as prills, a solid globule.
What are the disadvantages of using fertilizers?
Fertilizers have the following disadvantages:
- They are expensive.
- The ingredients in the fertilizers are toxic to the skin and respiratory system.
- Excessive use of fertilizers damages the plants and reduces soil fertility.
- Leaching occurs and the fertilizers reach the rivers causing eutrophication.
