Detailed explanation-1: -No-till farming leaves residue after a harvest that protects the soil from being eroded away. Also, it leads to fewer issues with frost, better stability for water absorption, and any loss of soil can be replaced easily over time.
Detailed explanation-2: -Tillage reduction can enhance soil aggregation, promote biological activity, and increase water holding capacity and infiltration rates. This leads to greater available soil moisture, improved soil tilth, and increased organic matter content.
Detailed explanation-3: -Producing crops in strips running across the slope can greatly reduce the risk of erosion by cutting surface water runoff approximately in half. Using strips effectively shortens the slope length, thereby slowing runoff of surface water from sloping fields.
Detailed explanation-4: -Disadvantages with reduced tillage may include reduced soil tem-perature and increased soil moisture contents in udic soil moisture regimes, which can decrease crop yields.
