How does flooding rice fields reduce the need for herbicides and pesticides in rice farming quizlet?

How does flooding rice fields reduce the need for herbicides and pesticides in rice farming? While rice has a submerged growth state, most weeds and pests do not. Flooding the fields causes the soil to degrade so weeds cannot take root. Residual herbicides and pesticides from previous seasons dissolve in the water.

How does flooding rice fields reduce the need for herbicides?

Explain how flooding rice fields reduces the need for herbicides and pesticides in rice farming. Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop.

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.

What is the purpose of strip cropping Edgenuity?

Strip cropping is help to stop the soil erosion by creating natural dams for water to helping​ to preserve the strength of the soil.

Which of the following best explains why soil conservation is important to human agriculture quizlet?

Which of the following best explains why soil conservation is important to human agriculture? It is easier to prevent the degradation of old soil than it is to generate new soil.

Are GMOs Good or Bad? Genetic Engineering

Why soil conservation is important to human agriculture?

Soil conservation is proven to increase the quality and quantity of crop yields over the long term because it keeps topsoil in its place and preserves the long term productivity of the soil. To grow enough food not only for ourselves; but also for people in third would countries where there are food shortages.

How do organic farming practices relate to soil health?

Higher Matter. Soils rich in organic matter hold more air and water and produce higher yields than soils low in organic matter. They also supply a steady release of nutrients to plants, inhibit erosion, and host a robust population of beneficial microorganisms.

How does strip farming prevent soil erosion?

Aside from improving soil fertility, field strip cropping reduces soil erosion. Due to the strip of soil in between the crops, erosion of wind and water is prevented, since the strip serves as a break in the movement of both water and wind.

How does the strip cropping helps to prevent soil erosion?

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.

What is strip cropping Mcq?

Strip cropping is a method of cultivating crops to prevent soil erosion. In strip cropping different crops are grown on the same field in different strips or patches, usually alternatively. It is very useful.

Why is Dutch Agriculture critically dependent upon technology quizlet?

Why is Dutch agriculture critically dependent upon technology? It produces almost 50% of the world supply of cut flowers and indoor plants. It relies almost exclusively on genetically engineered crops. Dutch agriculture is characterized by plant production in greenhouses.

How can pesticide use be harmful to human agriculture?

Pesticides can contaminate soil, water, turf, and other vegetation. 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.

What is the difference between selective breeding and genetic engineering in the development of food crops with desirable traits?

The difference is that traditional forms of breeding change the plant's genetics indirectly by selecting plants with specific traits, while genetic engineering changes the traits by making changes directly to the DNA.

How does the release of carbon dioxide by microorganisms benefit plant life quizlet?

How does the release of carbon dioxide by microorganisms benefit plant life? It reduces the acidity of water in soil, which increases water absorption and provides plants with necessary water.

Which of the following is a way that climate affects soil formation?

Climate affects soil formation by determining the rate of weathering and erosion. Warmer temperatures and increased rainfall increase the rate of weathering, contributing more mineral material for soil formation. Climate also determines the types of organisms that are in a given area.

Why might soils rich in organic matter not be fertile?

Soil fertility comes from a balance of organic matter and other mineral nutrients. b. Large amounts of organic material make soil retain too little water.

What steps can be taken to control soil erosion in the hilly areas?

Ans. Following steps are taken to control the soil erosion in hilly areas: (i) Contour ploughing: this refers to ploughing along contour lines. (ii) Terrace farming: construction of steps along the hilly areas by cutting the rock layers to reduce the flow of rivers. (iii) Plugging of gullies to prevent gully erosion.

What are the advantages and disadvantages of strip cropping?

The advantages and disadvantages of strip cropping are similar to those for contouring. Strip cropping also tends to filter out the soil in the runoff through the strip with the closely grown crop. On the negative side, one crop may tend to harbor (host) plant diseases and pests which are detrimental to the other crop.

What is stripping in agriculture?

Strip cropping is a method of farming which involves cultivating a field partitioned into long, narrow strips which are alternated in a crop rotation system. It is used when a slope is too steep or when there is no alternative method of preventing soil erosion.

How do plant roots slow down erosion?

Plant roots hold the soil in position and prevent it from being blown or washed away. Plants break the impact of a raindrop before it hits the soil, reducing the soil's ability to erode.

How does sustainable agriculture aid in soil conservation?

Planting cover crops and perennials.

These crops protect and build soil health by preventing erosion, replenishing soil nutrients, and keeping weeds in check, reducing the need for fertilizers and herbicides.

Which of the following is a method helps in slowing the water runoff and prevents soil from being washed away along the slope?

A method widespread among market gardeners, mulching is very effective in helping infiltration of rainwater, reducing runoff and evaporation, and protecting the soil against erosion.

How are weeds controlled in organic farming?

During summer and fall, organic farmers sterilize their soil through solarization. In this process, a clear plastic film is placed over an area after it has been tilled and tighly sealed at the edges. Solarization works when the heat crated under the plastic film becomes intense enough to kill weed seeds.

How organic farming can be used for improving land quality?

Organic agriculture sustains healthy soils by:

Improving water infiltration and retention capacity through high levels of organic matter and permanent soil cover, such as cover crops or mulch, which substantially reduce the amount of water needed for irrigation.

How does organic farming help in saving soil quality?

Answer. Explanation: By increasing the amount of organic matter in the soil, organic farmers enhance the soil's ability to absorb water, reducing the impacts of drought and flooding.
