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.
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.
Which of the following best explains why soil conservation is important to human agriculture?
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.
Which of the following is true about crop rotation?
All the statement mentioned in given options are true about the crop rotation. It uses less chemical-based fertilizer as nitrogen and other lost nutrients are fixed naturally in the soil. It maintains the soil fertility as beans and groundnuts fix nitrogen in the soil.
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 are farmers in the Netherlands reducing their impact on the planet?
They've almost completely eliminated the use of chemical pesticides on plants in greenhouses, and since 2009 Dutch poultry and livestock producers have cut their use of antibiotics by as much as 60 percent.
How does industrial agriculture promote farming techniques that are ecology destructive?
Industrial agriculture harms the environment through pollution of air soil and water. Air emissions from livestock operations make up 14.5 percent of global greenhouse gas emissions. Conventional crop production degrades soil health and causes soil erosion.
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.
Why is conservation of soil important suggest three different ways of soil conservation?
It helps in maintaining the food security of the world. (i) By encouraging terrace farming and contour ploughing. (ii) By promoting afforestation. (iii) By controlling overgrazing by animals.
Why should we conserve soil and prevent soil erosion?
Why is soil conservation important for sustainability? Simply put, without soil conservation, soil erosion would increase. Soil erosion impacts markets worldwide, including $8 billion in losses due to lower crop yields and increased water usage.
How does intercropping reduce the need for herbicides?
Intercropping and cover cropping are practices that increase diversity in the cropping system and enhance the utilization of resources such as light, heat and water. These practices can also help to suppress weeds and increase the likelihood of being able to reduce herbicide use in the cropping system.
How does crop rotation prevent pests?
The goal of crop rotation is to reduce the amount of the pest population present in the soil. Some pathogens that cause diseases survive in the soil from year to year in one form or the other, usually as sclerotia, spores, or hyphae. Rotating to non-host crops prevents the buildup of large populations of pathogens.
How does flooding rice fields reduce the need for herbicides and pesticides in rice farming a while Rice has a submerged growth state most weeds and pests do not?
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.
What is the meaning of pastoral farming?
Pastoral farming (also known in some regions as ranching, livestock farming or grazing) is aimed at producing livestock, rather than growing crops. Examples include dairy farming, raising beef cattle, and raising sheep for wool. In contrast, arable farming concentrates on crops rather than livestock.
Which country is the best in agriculture in the world?
China is the world's largest grain producer, yet has grown more dependent on food imports in recent decades. Much of India's output is produced by subsistence farmers and consumed locally. The U.S. is the world's top food exporter thanks to high crop yields and extensive agricultural infrastructure.
How can we reduce the environmental impact of agriculture?
Soil conservation methods, such as contour planting or no-till farming, reduce levels of soil erosion, as these methods help to keep the soil in place during heavy rains or floods, which is an increasing concern due to climate change.
How can we increase crop production without harming the environment?
Developing pest- and disease-resistant seeds through traditional breeding or genetic engineering can increase yields and reduce pesticide use. Cultivars suited to local conditions and weather extremes, such as drought and heat, can also help farmers produce more food without degrading ecosystems.
How can farmers prevent soil erosion and keep their soil as healthy as possible?
Planting Vegetation as ground cover: Farmers plant trees and grass to cover and bind the soil. Plants prevent wind and water erosion by covering the soil and binding the soil with their roots. The best choice of plants to prevent soil erosion are herbs, wild flowers and small trees.
Why should we conserve soil write three ways in which we can conserve it?
Soil erosion eliminates the top layer of the soil, thus removing all necessary organic matters and nutrients necessary for plants to grow and produce fruits. The three important methods of soil conservation are afforestation, crop rotation, contour ploughing.
What is soil conservation suggest some measures to conserve soil class 11th?
soil conservation is the process of saving or conserving soil from soil erosion or prevent it from getting eroded or becoming less fertile. by planting trees and plants we can conserve soil. we should not throw garbages like plastics item on the ground. using less insecticide and pesticides we can conserve soil.
What are the methods of preventing or reducing soil erosion?
(i) Afforestation : Forests reduce erosion as the roots of trees hold the soil in place. (ii) Shelter belts : Trees planted in lines or hedges around farmland reduce erosion by reducing the speed of the wind. (iii) Contour ploughing : Farmers plough land so that furrows lie across the natural slope of the land.
What is intercrop farming?
Intercropping involves cultivating two or more crops in a field simultaneously. In addition to cash crops, cover crops are also sometimes used in intercropping. This practice has regained attention worldwide, particularly in the tropics due to its beneficial effects on soil fertility and nutrient cycling. …
What are the benefits of intercrop?
Benefits Of Intercropping
- Increased profit. …
- Ergonomic usage of land. …
- Protection of the cash crop. …
- Prevention of soil erosion and crust. …
- Added nutrients for the main crop. …
- Reduction of fertilizer applications.
How does crop rotation help with pesticides?
A proper crop rotation is an excellent preventive tool against specific weeds, insects and diseases. Growing a various selection of crops year after year encourages the use of herbicides with different modes of action, which delays the development of herbicide-resistant weeds.
Why do they flood rice fields?
Growing rice requires the flooding of fields for several months in the summer. And since crop burning was restricted by the state of California in the 1990s, many rice growers flood their fields in winter to soften the stubble and makes it easier to till in the spring.
How does rice farming affect the environment?
Global rice production is releasing damaging greenhouse gases into the atmosphere, doing as much harm as 1,200 average-sized coal power stations, according to the Environmental Defense Fund (EDF).
How can farmers improve production in pastoral farming?
Pastoral farming is a non-nomadic form of pastoralism in which the livestock farmer has some form of ownership of the land used, giving the farmer more economic incentive to improve the land. Possible improvements include drainage (in wet regions), stock tanks (in dry regions), irrigation and sowing clover.
Are farmers rich in USA?
Farm operator households have more wealth than the average U.S. household because significant capital assets, like farmland and equipment, are generally necessary to operate a successful farm business. In 2020, the average U.S. farm household had $1,714,559 in wealth.
Can China feed itself?
The simple answer is it can't. It takes about 1 acre (half a hectare) to feed the average U.S. consumer. China only has about 0.2 acres of arable land per citizen, including fields degraded by pollution.
How agricultural management helps in the control of water pollution?
How agricultural management helps in the control of water pollution? Explanation: Land use is one of the agricultural management which helps in the control of water pollution. It includes crop rotation systems and the proportion of the land area devoted to permanent crops relating to annual tillage crops.
