What are the advantage and disadvantages of organic pesticides?

While organic pesticides are for the most part safer and more ecologically sound, they are not perfect. They usually have a shorter residual activity (they don’t last as long) than chemicals; they’re often more expensive than conventional pesticides, and for serious problems, they may not be 100% effective.

Which is an advantage of aquaculture apes quizlet?

Aquaculture can alleviate human caused pressure on native fisheries.

What is a disadvantage of using aquaculture to produce fish?

What is the most effective way to protect groundwater quizlet?

because of the difficulty and expense of cleaning up a contaminated aquifer, preventing contamination is the least expensive and most effective way to protect groundwater resources.

What are the advantages of organic farming?

Compared with conventional agriculture, organic farming uses fewer pesticides, reduces soil erosion, decreases nitrate leaching into groundwater and surface water, and recycles animal wastes back into the farm. These benefits are counterbalanced by higher food costs for consumers and generally lower yields.

Why is natural better than synthetic?

Advantages:

  • Chemical fertilizers are predictable and reliable.
  • The Fertilizer can be used in poor soil to make it fertile immediately.
  • They add a sufficient amount of nutrients needed by the plant.
  • They contain the three essential nutrients (NPK) needed for plant growth.

What are the advantages of synthetic fertilizers?

Synthetic:

  • Faster acting. They’re faster acting than organic making them a good choice for aiding plants in severe distress from nutrient deficiencies.
  • Easy to handle. These fertilizers, which come as dry, granular pellets or water-soluble products, also provide even, consistent feeding.
  • Inexpensive.

What are advantages and disadvantages of organic fertilizers?

Their major advantage is adding bulk to the soil. Except for manure, the organics generally release their nutrients over a fairly long period. However, the potential drawback is that they may not release enough of their principal nutrient at a time to give a plant what it needs for best growth.

What is the difference between organic and synthetic pesticides?

Organic pesticides are generally considered to be pesticides derived from naturally occurring sources such as minerals, plants, or animals. … Some synthetically produced pesticides meet the criteria for use in organic agriculture. For example, copper sulfate and paracetic acid can be used for plant disease control.

What are the disadvantages of aquaculture quizlet?

Disadvantages of Aquaculture: Technology not available for many possible crops. Lack of knowledge about aquaculture. Competition from wild fish and seafood.

Why is aquaculture good for the environment?

Aquaculture offers many environmental benefits, relative to other forms of livestock farming. Marine aquaculture operations typically have a smaller carbon footprint, and require less land and fresh water. They are more efficient at converting feed into protein for human consumption than beef, pork, and poultry.

Does aquaculture use antibiotics or synthetic chemicals?

Antibiotics are widely used in aquaculture. Intensive farming drives indiscriminate use of antibiotics, which results in residues of antibiotics in cultured aquatic products and bacterial resistance.
