Write a paragraph in your own words on the following:
Weeding

Answer 1

Hint: Weeding is an important control method practiced in many crops so that the plants do not need to compete themselves for growth.

Complete answer: The removal of weeds is useful because these unwanted plants compete with the crop for space, water, and nutrients.
1. Weed control should usually be done in an early crop stage, as this is more practical and more effective. The wedding has to be repeated 2 or 3 times, whenever weeds start to grow again.
2. Weeding has some other advantages like it helps to alter the micro-climate below the plants. Sun and wind can penetrate deeper into a weeded crop and reduce the humidity. This can have a positive impact on pest populations and some diseases.
3. Weeding also helps to loosen the soil. Water can infiltrate more rapidly and the roots of cultivated plants can develop in a better way.
4. While weed control is important, keeping a few spots of weeds as a refuge will help to conserve the eco-system. Weeds can be controlled biological, cultural, mechanical, or chemical (herbicides) methods.

Additional information: However, the use of chemicals can have adverse side effects on the environment and it involves risks for the farmers who have to handle the dangerous substances. Perennial weeds with bulbils, such as lesser celandine and oxalis, or with persistent underground stems such as couch grass or creeping buttercup store reserves of food, and are thus able to persist in drought or through winter.
Some perennials such as couch grass exude allelopathic chemicals that inhibit the growth of other nearby plants.

Note: Strategic weed management is a process of managing weeds at a district, regional or national scale.
