What are bio fertilizers?
Bio-fertilizers are substances which contain living microorganisms. When bio-fertilizers are applied to seeds or soil, they promote the growth of the plant by increasing plant nutrients.
What's the difference between artificial and natural fertilizer?
Artificial fertilizers are made chemically. They emphasize three main nutrients: nitrogen, phosphorus, potassium. Because of their narrow nutrient focus, they can create imbalances in the soil that have plant consequences. For example, too much nitrogen results in lush vegetative growth at the expense of bloom or fruit. Artificial fertilizers act quickly. They concentrate on improving plant yield. Natural fertilizers are made from animal or plant material such as bonemeal, compost, manure, or seaweed. They are slow releasers of nutrients into soil. They concentrate on improving soil structure. Artificial fertilizers are also called synthetic fertilizers. They are made through a chemical process. They tend to focus on the three main nutrients of the 18 available in healthy soil: npk = nitrogen, phosphorus, potassium. They tend to be easy to apply, and fast-acting. They aim to improve plant growth. However, they also tend to be overused. And they are the most common contributor to polluted runoff. Natural fertilizers are made from animal or plant material. Manure is probably the most common example. But other natural fertilizers are made from bonemeal, compost, and seaweed. They tend to be slow-releasers of nutrients into the soil. The reason is that they aim to improve soil structure and, as a result, plant growth.
Importance of nitrogen?
Nitrogen compounds are used to make ammonia based fertilizers. Ammonia helps the plants in the soil to generate nutrients when there is adequate water and air in the soil.
Why is soil so importany in photosynthesis?
Thirteen essential minerals (Nitrogen, Phosphorous, Potassium, Calcium, Magnesium, Sulfur, Boron, Copper, Iron, Chloride, Manganese, Molybdenum, and Zinc), which come from the soil, are dissolved in water and absorbed through a plant's roots. There are not always enough of these nutrients in the soil for a plant to grow healthy. This is why many farmers and gardeners use fertilizers to add the nutrients to the soil.
Can a fruit in the plant live without food?
Plants need water, sunlight and nutrients from the soil. Without all three of these, they will not grow. Potted fruit plants have restricted growth because the roots can't absorb natural nutrients from the soil.
Does the soil of organic farming last longer than conventional farming soil?
In true organic farming, the soil is built up with organic matter, which means nutrients in the soil are replenished. In non-organic farming, fertilizers are used to replenish certain nutrients only, while other nutrients may be depleted. In that sense, soil (nutrients in the soil) last longer in organic farming.
What will happen if a farmer only plants and harvests crops of cotton for seven years without adding fertilizers or other nutrients to the soil?
draining of nutrients from the soil
One advantage of crop rotation is?
Nutrients in the soil are replenished.
What does fertilizers do?
Fertilizers place nutrients in the soil that are not naturally there. Just keep in mind the difference between fertilizers and soil conditioners. Soil conditioners are items that overall help the soil. So fertilizers are soil conditioners but not all conditioners are fertilizers.

What are chemicals that can be added to soil which add nutrients?
fertilizers
What are the effects of fertilizers in the Earth?
Fertilizers add nutrients and minerals to the soil so plants can grow.
Why are fertilizers important to the farming industry?
they increase the nutrients in soil.
What fertilizers for?
It helps put nutrients in the soil and this helps the plants in it to grow.
What makes fertilizers a benefit to the farming industries?
They increase the nutrients in soil.
Is a disadvantage of the overuse of artificial fertilizers?
The nutrients in artificial fertilizers do not stay in the soil for very long. For this reason, gardeners must apply inorganic fertilizers to their soil more often than organic fertilizers. Inorganic fertilizers that release their nutrients into the soil more slowly, and thus require fewer applications, are available from some manufacturers. Excess nitrogen causes plants to die
