Answer:

  1. Quantity and quality of sunlight.
  2. Soil aeration.
  3. Presence of herbicides.
  4. Presence of pests and diseases.
  5. Water availability.

Explanation:

Weeds are all species that are born without human assistance, sporadically appear in the soil, starting to compete for light, space and nutrients and undermine the development of planned cultivation. In addition, weeds tend to spread quickly and quantitatively, competing for space in their fields.

Before establishing an economically viable crop in an area, weed management needs to be done. They must be removed and management must be done so that they do not grow back. For this reason, it is important to know what are the factors that limit weed growth. These factors are:

  1. Quantity and quality of sunlight.
  2. Soil aeration.
  3. Presence of herbicides.
  4. Presence of pests and diseases.
  5. Water availability.

5 Why is it easier to digest sour milk than fresh milk?​
Katyanochek1 [597]

Sour milk contains less lactose than the fresh milk, as the sour milk gets converted to lactic acid and bacteria which enhances the digestion process. One important reason is that proteins take more time in getting digest than other nutrients. We know that fresh milk has a large amount of lactose.

Explanation:

The lactic acid bacteria have many benefits. They improve lactose digestion in the stomach. The lactase activity of the bacteria performs  the task of digesting lactose in the product once it reaches the intestine thus fuelling the process of digestion in case of sour milk.

In fresh milk, the casein protein in contact with milk forms curdles which are difficult to digest.
