[amp_mcq option1=”Soil structure” option2=”Nutrient availability” option3=”Water drainage” option4=”All of the above” correct=”option4″]<\/p>\n

The correct answer is: d) All of the above<\/strong><\/p>\n

Kankar is a hard, calcium carbonate nodule that forms in some soils. It can affect soil structure, nutrient availability, and water drainage.<\/p>\n

Kankar can make soil more compact and less porous, which can reduce water infiltration and drainage. This can lead to waterlogging and poor crop growth. Kankar can also reduce the availability of nutrients, such as phosphorus and potassium, by binding them to the soil particles. This can make it difficult for plants to absorb these nutrients.<\/p>\n

In addition, kankar can make it difficult to till the soil, which can be a problem for farmers.<\/p>\n

Overall, kankar can have a negative impact on soil quality and crop production.<\/p>\n
