Which of the following statements is FALSE regarding the effects of soil tillage?

O Tillage reduces water infiltration.

O Tillage reduces soil organic matter.

O Tillage causes soils to get darker in color.

O Tillage reduces soil pore space, which is necessary for root aeration and root growth.

C. Tillage causes soils to get darker in color.

Explanation:

Tillage involves mixing and turning of the soil using certain tools. However this process could lead to decreased water infiltration, decreased level of soil organic matter and also making the soil more compact and susceptible to dangerous crop insects. Tillage doesn't change the colour of the soil. The soil colour is determined by the water content in it and the basic nutrients it contains

Option (3)

Explanation:

Soil tillage is usually defined as the preparation and modification of soil by digging, overturning and stirring it, in order to grow crops. This has become essential for cultivation but it has many negative effects, as it leads to the erosion of soil particles, degrades the water quality, reduces the percolation of water into the subsurface, organic materials present in the soil are also decreased, and also the pore spaces between the materials also decreases.

Soil tillage has no impact on the color of the soil. It does not lead to the changing of the color. The soil attains its color depending on the mineral it comprises.

Thus, the correct answer is option (3).
