Why do farmers normally use a mixture of manure and fertilizers in the field Class 8?
Answer: Farmers normally use a mixture of manure and fertilizers in their fields to increase the yield and production of crops. Manure is good for plants as it provides them with organic nutrients but it lacks some important nutrients like nitrogen, phosphorous and potassium.
Why does a farmer add a mixture of fertilizer and manure to the soil what are the natural methods to replenish nutrients to the soil?
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose …
Why do we use manure and fertilizers?
Manure adds nutrients to the soil without affecting its fertility. It does not damage the crops and produces healthy plants. Fertilizers are chemicals which lower the fertility of the soil if used regularly.
What is difference between manure and fertilizers?
Manure is an organic substance that is obtained from decomposition of vegetables and animal waste. Fertilizers are inorganic substances manufactured in factories. Manures are relatively less rich in plant nutrients, they only remove general deficiency of soil.
What is the purpose of fertilizer?
Fertilizers are applied to replace the essential nutrients for plant growth to the soil after they have been depleted. Excess amounts of fertilizers may enter streams creating sources of nonpoint pollution. Fertilizers most commonly enter water sources by surface runoff and leaching from agricultural lands.
What is tilling Class 8?
Tilling or ploughing is the process of preparing the soil for the cultivation of seeds by digging, ploughing and overturning the soil. It ensures proper mixing of the nutrients and uproots the weeds growing beforehand.
Is manure better than fertilizers?
Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility.
What is difference between manure fertilizer?
What is tilling ploughing Class 8?
Ploughing is the process involving loosening and turning of soil in agricultural fields. It is also known as tilling. Usually done with the help of a wooden or iron plough. – Tilling of soil helps in loosening and turning off the soil, the nutrient-rich soil is distributed evenly and also it improves aeration.
Manure contains nitrogen, phosphorus, and other nutrients that plants need to grow. Proper use of manure as a fertilizer minimizes nutrient pollution to water resources and helps build healthy soils. Manure nutrients can also be used to grow worms, insect larvae, algae, or other living organisms.
What is the best method to evaluate soil fertility?
Soil testing is an excellent method for estimating the fertility status of a soil, and it provides valuable information for developing a sound fertility management program. There are four critical steps to a soil test: sampling, analysis, interpretation and recommendation.
What are the 5 difference between manure and fertilizers?

Why do farmers use both manure and chemical fertilizer?
According to the University of Florida, farmers reported that using both types together results in higher crop yields. Since there is not enough manure for all farmers to have enough to fertilize their soil, and chemical fertilizer is less expensive, farmers make more money using chemical fertilizers than they would otherwise.
What happens when you mix manure with soil?
For instance, mixing manure with sandy soils helps to retain moisture levels. Adding manure to compacted soil helps loosen the soil. Manure produces increased soil carbon, which is an important source of energy that makes nutrients available to plants.
What are the benefits of manure in the garden?
As the soil absorbs manure, nutrients are released. This enriches the soil, which in turn, helps the plants. The most important benefit of using manure in the garden is its ability to condition the soil.
Why do farmers apply manures before seed sowing?
Manures are applied to soil quite before seed sowing to add organic carbon , micronutrient as well as to maintain an equilibrium population of microorganisms which keeps the pathogen and nematode population under control. Beside this manures also improve soil structure , water holding capacity and soil reactivity (pH). So manures are ad… Loading…
Why do farmers use manure as a fertilizer?
It provides useful nutrients and minerals to the soil for cultivation of crops. For the reason that after every harvest the crops absorbs these vital minerals from the soil thus making it weak to sow any seeds and it is also use in between the mid growth stage to help nourish and gain strength to produce a healthy harvest.
Can you use manure as a soil amendment?
Manure can be used as a soil amendment or as a component in compost, but you should not plant directly into manure without combining the manure with soil or other mediums. The high levels of nitrogen and ammonia can “burn” plants if manure is not diluted in a soil mixture.
What foods can be used as fertilizer for plants?
Organic Manures like Banana Peels,Coffee grounds,egg shells, sea weeds,molasses, urine,worm casting even pet foods can be used as Manure which is very good for the growth of plants.
