How do you add nutrients to soil?
by using fertilisers.
Why are chemical fertilisers expensive?
Cheap fertilizer is not good and good fertilizer is not cheap. So, chemical fertilisers are expensive because they contain nitrogen, phosphorus and potassium elements.
What are the uses of chemical Fertilisers?
tey are used t remove small insects
Does fertilisers have sulphuric acid in?
Artificial fertilisers do
Why does garden soil become acidic?
Garden soils will gradually become acidic as the rain that falls is slightly acidic and most fertilisers are also.
Pollution due to excessive fertilisers used by farmers leading to Eutrophication?
Over-application of chemical fertilisers or application of chemical fertilisers at a time when the ground is waterlogged or the crop is not able to use the chemicals, can lead to surface runoff or leaching into groundwater Storage and application of some fertilisers in some weather or soil conditions can cause emissions of the greenhouse gas nitrous oxide (N2O) primarily associated with the use of artificial fertilisers, because of the massive quantities applied and the destructive nature of chemical fertilisers on soil nutrient holding structures The high solubility of chemical fertilisers also exacerbates their tendency to degrade ecosystems
What is the difference between Fertilisers and Bio-fertilisers?
The difference is that chemical fertilizers have chemicals. And bio fertilizers don't.
What are the two main kinds of plant fertilizers?
Organic fertilisers - those that originate from the processing of organic or vegetative materials. Examples are bone meal, humus, blood meal, urea (although urea is part processed). organic fertilisers are normally much more diluted than chemical fertilisers and take a longer time to affect the growth of the plant, they are however longer acting and normally add to/ improve the structure of the soil. Chemical fertilisers - these are compounds that are manufactured from chemicals or chemical byproducts (eg. through the gas and petroleum industry). They are concentrated, fast acting and come in a wide variety of formulations. They can however damage crops if they are incorrectly applied, leach easily from the soil (contributing to the pollution of ground water) and they (normally) have no long residual action in the soil. Examples of these are: NPK formulations, ammonia nitrate, ammonia suphate etc.
How do you add nutrients to soil?
by using fertilisers.
What are the Suggestions to prevent harmful effects of chemical fertilisers?
The controlled use of fertilisers and use of biodegradable fertilisers are the way to solve this problems.
How does soil become acidic?
fertilisers and acid rain
Why are chemical fertilisers expensive?
Cheap fertilizer is not good and good fertilizer is not cheap. So, chemical fertilisers are expensive because they contain nitrogen, phosphorus and potassium elements.
What is the effect of the use of artificial fertilisers on soil structure?
Artificial fertilisers are used on soils because once the crops are harvested the soil is left without many minerals. The minerals they need are kept in the ground even if the crops are harvested with the help of artificial fertilisers. This is beneficial for the soil because it prevents the fields from laying fallow (where no crops are grown).
What are 4 major causes of soil degradation?
Soil erosion and depletion are the major threats to soil as a resource. Both human and natural factors can lead to degradation of soils . Factors which lead to soil degradation are deforestation, overgrazing, overuse of chemical fertilisers or pesticides, rain wash, landslides and floods.
What is the difference between a chemical and an organic fertiliser?
the difference between organic and chemical fertilisers is that organic fertilisers are naturally made for example cow dung and chemical fertiliser are made by man himself in industries for example ammonium nitrate.
What are some methods farmers use to keep their soil healthy and productive?
they use soil and plant food. also fertilisers
Which factor have lead to the reduction of the water table in India?
use of chemical fertilisers.
