What factor usually has the greatest effect on soil formation *?


Among the 5 factors climate has the greatest influence on soil formation. In areas of high rainfall and temperature the soils formed are often similar even though the parent materials are different.

How does Dutch agriculture use technology to fully control the growing environment of crops?

Dutch agriculture is characterized by the growth of plants and crops in greenhouses. In greenhouses all aspects of growth can be artificially controlled including the artificial imposition of climatic conditions and artificial growth patterns (i.e. hydroponics) and even the mechanical automation of farming.

How do organic farming practices relate to soil health?

Organic agriculture builds up this ecosystem living within the soil by using compost instead of synthetic fertilizers which harm the life in the soil. By using compost a natural input organic farming prevents contamination and diseases spreading to the plants.

Which of the following is a benefit of intensive farming?

The main advantage of intensive farming is its increased performance when higher yields are harvested from smaller territories. This brings economic benefits to landowners and provides food for the growing population. Intensive agriculture fully satisfies the market demand even in densely inhabited areas.

How do pesticides and herbicides affect humans?

Pesticides can cause short-term adverse health effects called acute effects as well as chronic adverse effects that can occur months or years after exposure. Examples of acute health effects include stinging eyes rashes blisters blindness nausea dizziness diarrhea and death.

How do pesticides improve the agricultural products?

Pesticides help conserve the environment.

See also how does biomass affect the environment

They enable farmers to produce more crops per unit area with less tillage thus reducing deforestation conserving natural resources and curbing soil erosion. Pesticides are also critical for the control of invasive species and noxious weeds.

Why should we reduce the use of pesticides in agriculture?

In addition to killing insects or weeds pesticides can be toxic to a host of other organisms including birds fish beneficial insects and non-target plants. Ecological effects of pesticides extend beyond individual organisms and can extend to ecosystems.

Which of the following is a benefit of pesticide use?

The benefits of pesticides include increased food production increased profits for farmers and the prevention of diseases. Although pests consume or harm a large portion of agricultural crops without the use of pesticides it is likely that they would consume a higher percentage.

Why might soils rich in organic matter not be fertile?

Why might soils rich in organic matter not be fertile? a. Soil fertility comes from a balance of organic matter and other mineral nutrients. … Large amounts of organic material make soil retain too little water.

What is the purpose of strip cropping?

Strip cropping helps to stop soil erosion by creating natural dams for water helping to preserve the strength of the soil. Certain layers of plants will absorb minerals and water from the soil more effectively than others.

Why might genetically engineering a crop to be herbicide resistant result in producing weeds that are herbicide resistant quizlet?

Farmers do not have to use harsh chemicals to save their crops. … Why might genetically engineering a crop to be herbicide resistant result in producing weeds that are herbicide resistant? The weeds that are not affected by the herbicide are able to reproduce.

What are the advantages of using genetic engineering to modify crops to be pest resistant?

Some benefits of genetic engineering in agriculture are increased crop yields reduced costs for food or drug production reduced need for pesticides enhanced nutrient composition and food quality resistance to pests and disease greater food security and medical benefits to the world’s growing population.

What are the advantages and disadvantages of genetic engineering in our food or agriculture?

Genetic engineering may create stronger healthier plants and animals. It may also create more plants and animals with mutations or birth defects that can harm the species. We have already seen in humans that gene therapies can lead to additional genetic conditions even if the targeted condition is improved.

How does genetic engineering affect the environment?

Genetic modification produces genetically modified animals plants and organisms. If they are introduced into the environment they can affect biodiversity. For example existing species can be overrun by more dominant new species.

Why does selective breeding reduce variation?

Because of selective breeding future generations of selectively bred plants and animals will all share very similar genes which will reduce variation. … Inbreeding can lead to a reduced gene pool making it more difficult to produce new varieties in the future.
