What are two ways people can protect the soil?
Implementing conservation practices such as crop rotation, cover cropping, and reduced tillage to prevent soil erosion and maintain soil structure. Avoiding the overuse of chemical fertilizers and pesticides, and instead using organic farming practices to promote healthy soil biology and reduce chemical contamination.
What are the disadvantages of using pesticides?
Pesticides are of various chemical nature which on being applied to plants nuture them by warding of pests. Pesticides, when applied to plants, on excess irrigation, they percolate down the soil thus polluting the depleting reservoire of groundwater. Pesticides are composed of various chemicals like cadmium, mercury which enter the human body via the food chain which has its dependence on groundwater. Chemicals like cadmium cause death on consumption. Pesticides not only harm the insects and pests but also the local fauna like snakes and earthworms which are natural pesticides and decomposers. Snakes kill the rats living in the farm.
What is chemical shorthand?
Chemical shorthand is a method of representing chemical elements and compounds using symbols and formulas. It allows for concise communication of chemical information, such as in chemical equations, formulas, and reactions.
How fertilizers and pesticides cause soil pollution?
Fertilizers contain high levels of nutrients that can leach into the soil and water bodies, leading to nutrient imbalances and harmful algal blooms. Pesticides can persist in the soil, affecting soil organisms and disrupting the ecosystem. Both fertilizers and pesticides can also contaminate groundwater and surface water, leading to soil pollution.

What reason might a farmer have for using biological control instead of chemical pesticides?
A farmer might choose biological control over chemical pesticides to minimize negative impacts on the environment and human health, reduce chemical residues on produce, and promote sustainable agricultural practices. Biological control methods also have the potential for long-term pest management and are often more target-specific.
What is the chemical equation for pesticides?

Pesticides typically contain chemicals that target specific pests or regulate their growth. Some common types of pesticides include insecticides, herbicides, and fungicides, each with their own unique chemical composition.
How bio pesticides are beneficial over chemical pesticides?
It is supposed that biopesticides are not so dangerous for the environment as artificial pesticides.
What are some biological alternatives to chemical pesticides?
Some biological alternatives to chemical pesticides include introducing natural predators or parasites to control pest populations, using insecticidal soaps or oils derived from plants, and planting trap crops to attract pests away from main crops. Crop rotation and intercropping with pest-repellent plants can also help reduce the need for chemical pesticides.
What could be the slogan on natural pesticides?
the one and only solution against chemical pesticides
Advantage and disadvantage of modern farming?
The disadvantage of modern agriculture is that the use of chemical fertilizers and pesticides has a negative effect on the environment. The advantage of the modern agriculture is that the use of machine and the use of large irrigation systems help boost the crop production.
Why do farmers avoid using pesticides?
farmers avoid using pesticides because it is a chemical made in factories. It reduces the fertility of the soil and it also kills useful bacteria already present in the soil.AnswerUS farmers mainly avoid pesticides primarily due to their cost of both purchase and application. If any particular pest is not prevalent enough in the field to pay for the pesticide use, he will not apply it. Also, organic farmers must avoid using non-approved pesticides in order to have their crop be "certified."
Why are organic materials considered environmentally healthy?
Organic foods are grown without using any chemical fertilizers or pesticides. Many people prefer them for this reason.
