Hint: The methods from the above options which is not a method of soil conservation is the situation when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods.

Complete answer:
Overgrazing is the method which is not involved in soil conservation. Soil conservation is the process of preventing soil erosion and to stop the soil from becoming infertile. In mulching, a protective layer for example straw, grasses, etc is placed over the soil, which helps in retaining soil moisture and also regulates soil temperature. farming is a process during which a field is split into strips and different crops are grown in alternate strips to preserve soil fertility. Crop rotation means growing various kinds of crops on a similar field in succession which prevents the depletion of nutrients from the soil.

Additional Information:
Soil conservation - It is defined as the process of prevention of loss of the layer of the soil which is present on the top of the soil from the erosion or prevention of reduction in the fertility of the soil which is mainly caused by over usage, acidification, salinization or other chemical soil contamination.
In some lesser developed areas, Slash-and-burn and other unsustainable methods of subsistence farming are practiced in agriculture. Due to deforestation. lots of soil get eroded from the land, loss of nutrients present in the soil, and sometimes total desertification occurs. Techniques that are now used for improved conservation include crop rotation, cover crops, and some more techniques. These techniques affect both erosion and fertility of the soil. When plants die, they decay and become a part of the soil.

So, the correct answer is ‘Overgrazing’.

Note: When the worms present in soil excrete feces, a balanced selection of minerals and plant nutrients is formed into a form accessible for root uptake. Earthworm casts are on an average five times higher in the amount of available nitrogen, seven times richer in available phosphates, and eleven times richer in available potash than the surrounding upper 150 millimeters (5.9 in) of soil.
