What is a definition agrochemical?
Agro-chemicals are commercially produced, usually synthetic, chemical compounds used in farming — such as a fertiliser, pesticide or soil conditioner. Source Publication: Agricultural Policies in OECD Countries: Monitoring and Evaluation 2000: Glossary of Agricultural Policy Terms, OECD.
What are agrochemical and its uses?
Agrochemicals are pesticides, herbicides, or fertilizers used for the management of ecosystems in agricultural sectors. Rudimentary variations on agrochemicals have been used for millennia to improve crop yields and control the populations of agricultural pests.
What is the effect of agrochemical?
Agrochemicals seep into the surrounding land and water bodies, entering the food chain (bioaccumulation). Regarding their impact on crops, excessive use of such chemicals generates a significant amount of residues. These residues cause nutrient imbalance and quality-reduction of agricultural produce.
What are the examples of agrochemicals?
Agrochemicals include fertilizers, liming and acidifying agents (which are designed to change the pH), soil conditioners, pesticides, and chemicals used in the raising of livestock such as antibiotics and hormones.
How do you use agrochemicals?
Mix and prepare products in a well-ventilated area. Use only the amount and concentration specified by the label. Do not mix different products unless allowed by label directions. Keep children and pets away when mixing and applying chemicals.
What are agrochemicals Class 12?
What are the advantages and disadvantages of using agrochemicals?
Discuss advantages and disadvantages in using synthetic agrichemicals in forage production
| Advantages of Using Agrichemicals (Benefits) | Disadvantages of Using Agrichemicals (Risks) |
|---|---|
| Higher Crop Yields | Contamination of crop products with harmful chemical residues |
| Higher Crop Quality | Contamination of soils and groundwater |
How do agrochemicals affect the environment?
While agrochemicals increase plant and animal crop production, they can also damage the environment. Excessive use of fertilizers has led to the contamination of groundwater with nitrate, a chemical compound that in large concentrations is poisonous to humans and animals.
How many types of agrochemicals are there?
What are the types of agrochemicals? Agrochemicals include pesticides, insecticides, herbicides, fungicides, along with fertilizers and soil conditioners. Insects and animals are a severe plant risk.
What are agrochemicals in agriculture?
Agrochemicals are chemical products comprised of fertilizers, plant-protection chemicals or pesticides, and plant-growth hormones used in agriculture.
What are the effect of agrochemicals on environment?
Usually, make water unfit for humans and animals consumption. Diffusion of Agrochemicals in larger water bodies promotes the growth of algae which is again hazardous. Excess chemicals may lead to Eutrophication. Lead12 to water pollution thereby affecting aquatic habitats.
What is agro chemical based agriculture?
Agrochemical based agriculture is used to increase the food production. It includes use of agrochemicals such as fertilisers and pesticides.
What are two important benefits of pesticide use?
Pesticides help reduce waterborne and insect transmitted diseases. Such as malaria, Lyme disease and West Nile virus. Pesticides contribute to enhanced human health by preventing disease outbreaks through the control of rodent and insect populations.
Who is the father of agricultural chemistry?
IN the historiography of chemistry, Liebig’s Die organische Chemie in ihrer Anwendung auf Agricultur und Physiologie, 1 hereafter cited as “Agricultural Chemistry”, isoften identified with the emergence ofa new discipline. Liebig himself was glorified as the “father of agricultural chemistry”.
What are the two advantages of using agrochemicals?
How agrochemicals affect the soil?
Effect of agrochemicals has demonstrated the decreasing enzymatic action, increasing soil salinity and contamination, reduction in the population of beneficial insects and different feathered organisms, loss of biodiversity, contamination of air, and ground and surface water.
How are agrochemicals classified?
Classifications of Agrochemicals: In most of the cases, agrochemicals refer to pesticides which include insecticides, herbicides, fungicides, rodenticides, molluscicides, and nematicides. Agrochemical also includes fertilizers and soil conditioners.
