What is the purpose of strip cropping a prevent soil erosion B maintain nutrient levels?
It is a process in which farmers gather crops in alternate strips instead of just going all out and picking up everything that they can. This prevents erosion because the land can’t be moved, which is why it’s great for having farms on lands with slopes where erosion could be really troublesome.
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.
How does flooding rice fields reduce the need for herbicides and pesticides in rice farming?
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 are soil remediation techniques?
Remediation techniques which have been commonly used include: containment, pump-and-treat, extraction, stabilization/solidification, soil washing, air stripping, precipitation, vitrification, thermal desorption and biological remediation.
What are the methods of soil remediation?
Physical remediation techniques include soil washing, vitrification, encap- sulation of contaminated areas by impermeable vertical and horizontal lay- ers, electrokinesis, and permeable barrier systems. Soil washing is a technique widely used for removing heavy metals and organic pollutants from soils.
What is remediation of soil?
Soil remediation is a way of purifying and revitalizing the soil. It is the process of removing contaminants in order to protect both the health of the population and the environment. In short, the goal of the process is to restore the soil to its natural, pollution-free state.

What is the remediation process?
A short article explaining the basics associated with the remediation process and the benefits of an early contractor engagement. Site-remediation is the process of removing polluted or contaminated soil, sediment, surface water, or groundwater, to reduce the impact on people or the environment.
What is a remediation strategy?
Remediation Strategies help you to manage your environmental liabilities – specifically land and water contamination risks. We do this by providing a variety of services such as: Soil and Groundwater Contamination Assessment, to determine the significance of any residual contamination.
How do you remediate contaminated land?
In-situ methods for contaminated land treatment involve methods of immobilising, stabilising, washing, transforming or separating contaminants in the soil. By utilising these methods we are able to change the nature of the contaminant source in order to reduce the risk to the surrounding environment.
What is remediation in a lesson plan?
At a basic level, remediation (or reteaching) means “teaching again” content that students previously failed to learn. As a teacher recognizes misconceptions or errors in understanding, he or she may quickly redirect students through explicit remediation of that concept.
What are the methods of remedial teaching?
Solid remedial programs:
- Are research-based, using proven teaching methods.
- Teach step-by-step without skipping over content.
- Are conducted at the student’s pace.
- Offer regular reviews and practice exercises to reinforce learning and practice applying new knowledge.
What is the aim of remedial teaching?
The objective of remedial teaching is to give additional help to pupils who, for one reason or another, have fallen behind the rest of the class in the subjects of Chinese, English and Mathematics. Children with learning difficulties have the same psychological needs and characteristics as other children.
What is the role of a remedial teacher?
A remediation teacher is responsible for using multiple diagnostic tools to determine student needs. These tools include online and paper-based tests designed to test basic skills. The teacher also observes students as they work to identify areas of confusion.
What are the five elements of active learning?
different ways, each of these five elements helps students to: impart and receive information, clarify, organize, receive feedback, develop empathy, appreciate different perspectives, test ideas, see connections, create, recognize assumptions, prioritize, etc.
How do you promote active learning?
Approaches that promote active learning focus more on developing students’ skills than on transmitting information and require that students do something—read, discuss, write—that requires higher-order thinking. They also tend to place some emphasis on students’ explorations of their own attitudes and values.
What are the assessment strategies for online teaching learning?
Useful online assessment strategies
- Assessing with blogs.
- Assessing with discussion forums.
- Assessing with ePortfolios.
- Assessing with Wikis.
- Group tasks.
- Peer assessment.
What is the most effective strategy for distance learning?
Spacing or spreading out learning opportunities over time improves learning. For example, students will learn and retain more if they study 30 minutes M-F, rather than for 2.5 hours all on one day. Students should create a schedule with brief study sessions each day and stick to it.
