No‐Tillage Crop Production: A Revolution in Agriculture!

Summary

This narrative review traces the history and development of no-tillage agriculture from its demonstration in the 1950s through widespread adoption in the 1980s–2000s across North America, Australia, and South America. The authors document how modern herbicides, improved planters, and accumulated farmer experience enabled NT to become a sustainable alternative to conventional tilled systems, delivering benefits including reduced erosion, improved water and nutrient use efficiency, lower energy and labour requirements, and comparable or better crop yields. The review also identifies remaining research challenges for expanding NT adoption and realising its full benefits across diverse crop types and geographies.

Regional applicability

The paper focuses primarily on United States adoption and practice, which is directly relevant to UK farming policy and practice. However, the UK climate, soil types, and cropping systems differ substantially from those in the continental United States, and adoption rates in the UK remain considerably lower than the 23% reported for the US. The review's findings on erosion control, water use efficiency, and labour savings are transferable, though UK-specific agronomic trials would be needed to optimise NT for temperate maritime conditions and winter cereal-dominant rotations.

Key measures

Cropland adoption rate of NT (23% of total US cropland); soil erosion; water use efficiency; fertiliser use efficiency; crop yield; labour and machinery inputs; farm economics; soil and hydrological properties

Outcomes reported

The paper reviews the development, adoption trajectory, and agronomic and environmental impacts of no-tillage (NT) systems in the United States and internationally. It examines effects on crop yield, soil erosion control, water and fertiliser use efficiency, labour and energy inputs, and farm economics.
