Fiche created in January 2024
Note to the reader: This general fiche summarises all the environmental and climate impacts of NO TILLAGE AND REDUCED TILLAGE found in a review of 50 synthesis papers[1]. These papers were selected from an initial number of 359 obtained through a systematic literature search strategy, according to the inclusion criteria reported in section 4. The impacts reported here are those for which there is scientific evidence available in published synthesis papers, what does not preclude the farming practice to have other impacts on the environment and climate still not covered by primary studies or by synthesis papers.
The synthesis papers review a number of primary studies ranging from 8 to 678. Therefore, the assessment of impacts relies on a large number of results from the primary studies, obtained mainly in field conditions, or sometimes in lab experiments or from model simulations.
1. DESCRIPTION OF THE FARMING PRACTICE
- Description:
- Reduced tillage refers to methods involving low degrees of soil disturbance (e.g., minimum tillage, subsoil tillage, non-inversion, or shallow inversion).[2]
- No-tillage (or zero tillage) is a minimum tillage practice in which the crop is sown directly into soil not tilled since the harvest of the previous crop.[3]
- Conservation agriculture is a special case of no-tillage systems where minimum soil disturbance is combined with crop rotation (i.e., alternation of different crops) and permanent soil cover (including crop residues, mulch, and live mulch).[4]
- Conventional tillage in arable land involves soil inversion. It includes high-disturbance tillage practices, such as deep tillage, inversion tillage, mouldboard plough, disc plough.[5]
- Key descriptors:
- This review aims to analyse the impacts of reduced tillage and no-tillage, separately, compared to conventional tillage. The impact of conservation agriculture, considered as a special case of no tillage, is also reported in this review.
- The review also includes comparisons between no-tillage or reduced tillage combined with either permanent soil cover or crop rotation, and conventional tillage.
- Studies including various no-tillage and reduced tillage systems (sometimes defined as conservation tillage[6]) are excluded from this review, as the effects reported in the papers cannot be distinguished.[6]
2. EFFECTS OF THE FARMING PRACTICE ON CLIMATE AND ENVIRONMENTAL IMPACTS
We reviewed the impacts of no tillage (Table 1, left panel) and reduced tillage (right panel) compared to conventional tillage.
The table below shows the number of synthesis papers with statistical tests reporting i) a significant difference between the Intervention and the Comparator, that is to say, a significant statistical effect, which can be positive or negative; or ii) a non-statistically significant difference between the Intervention and the Comparator. In addition, we include, if any, the number of synthesis papers reporting relevant results but without statistical test of the effects. Details on the quality assessment of the synthesis papers can be found in the methodology section of this WIKI.
Out of the 50 selected synthesis papers, 51 included studies conducted in Europe, and 46 have a quality score higher than 50%.
Table 1: Summary of effects. Number of synthesis papers reporting positive, negative or non-statistically significant effects on environmental and climate impacts. The number of synthesis papers reporting relevant results but without statistical test of the effects are also provided. When not all the synthesis papers reporting an effect are of high quality, the number of synthesis papers with a quality score of at least 50% is indicated in parentheses. Some synthesis papers may report effects for more than one impact, or more than one effect for the same impact.
