Answer: c.no-till farming

Tillage is a method of mechanical agitation of soil before sowing seeds for growth of new crops. Tillage is done to reduce soil compaction. But there are some disadvantages associated with this it causes erosion of upper layer of soil, it decreases the minerals composition of soil and disturbs the natural microbial growth. No-till method is an agricultural practice in which the stalks are left on the crop fields to anchor the topsoil. It avoids the mechanical or physical agitation of soil. This is basically done to prevent soil erosion so, that roots can hold the soil in place. This technique is advantageous over tillage method. As, it retains the natural physical properties of soil. It increases the water retention capacity of soil. It increases the yield of the crops.
