3 Conservation agriculture in the World Total: 116,9 millions ha Canada 13,5 USA 26,5 Europe 1,2 Rest of the World 3,8 China 1,3 Brazil 25,5 Paraguay 2,4 Argentina 25,8 Australia 17.0 (Derpsch, R. and Friedrich, T., 2010)
4 Introduction In the last 30 years agriculture was characterized by: Intensive usage of the soil, Simplification in cropping systems, Reduction of yield increments Increase of the cost to produce yield, In this context tillage is a critical point
5 Critical aspect of tillage High energy required; Organic matter mineralization; Risk of erosion; Deterioration of soil structure; More evaporation from soil. Reconsider the role of soil tillage
6 Conservative agriculture Main characteristics Minimal soil disturbance, no soil layers inversion (sod seeding or minimum tillage) Permanent soil cover (crop residuals and cover crops) Crop rotation, against pest, diseases and weeds
7 Objectives of CA Main objectives are: Increase of soil s OM content, mainly in surface layers Reduction of erosion; Reduction of soil compaction; Increase of soil biomass and biodiversity; More efficiency of irrigation and fertilizers; Reduction of costs.
8 Increase of SOM. Crop residuals and no tillage (or reduced tillage) allows for Low OM mineralization rate Improvement of soil structure stability Better crop utrition Increase of microbial biomass and biodiversity Efficient water use (better hydrological characteristics) Reduction of CO 2 emissions
9 % S.O. OM trends (example) OM content (after 7 years for SS, and after 10 for MT) 2,25 2,00 1,75 1,50 +63% +52% 1,25 1,00 0,75 0,50 0, % 0, cm cm 0-20 cm cm 0-20 cm cm SS MT conventional Arato source: DiSAA experiments
10 Erosion control Erosion is at world level one of the main sources of loss of productivity (and water eutrophication). Erosion: from 0 to 200 t ha -1 of soil losses Erosion do not happens only in hillslopes, but also with a 1% soil slope Averaged results from some experiments: tillage Soil losses (t ha -1 ) Conventional 29.4 Sod seediing 3.8
11 Difficulties in implementing CA Yield reduction respect to conventional, mainly in the first years Risk of increase of chemical use for crop protection and weeds; Needs of special machinery; New technical knowledge needed for the new cropping systems. To avoid compaction there is the need of low-pressure pneumatics. (When there is compaction of soil it is difficult to go back in CA)
12 Precondition to apply CA Soil type machinery Weed management Irrigation management and hydraulic systems.
13 Precondition soil type CA is more difficult in: Silty soil: it is difficult to avoid compactation; Clay soil with Kaolinite. But is possible, due to an increase of organic matter CA is easy to implement in: Loam soils; Swelling (montmorillonite) Clay
14 Precondition Machinery Precision seeder for SS with localized fertilizer distribution Harrow for MT
15 Yield results
16 Po valley farms mais grain yield t ha MT SS Aziende Conventional convenzionali Production-reduction 13% in MT and 23% in SS Fonte: sperimentazioni Di.Pro.Ve
17 Wheat yield Conventional Yield reduction 11% in SS; in MT there is an increase of 6% Source: interal
18 Example at regional scale Source: AgriCO2ltura project
19 Production cost reduction Reduction in tillage = reduction in costs After an initial conversion period there is a reduction of chemical fertilizer usage and somewhat a reduction of expanses for crop protection. There is to consider also that yield reduction could be very low

22 Margine lordo ( /ha) 1750 Maize no subsidies Gross margin ha Agricoltura Conventional Convenzionale Minimum tillage Semina Sod seeding su sodo prezzo ( /t) Maize price t -1
23 NEW FRONTEERS IN CA SUBIRRIGATION Max irrigation efficiency (up to 90%) due to low evaporation, no runoff, reduced leaching; Incrase in yield: due to the possibility of late fertilization of maize; Soil surface is dry: reduction of weed development, and diseases, low use of chemicals Reduction of labor costs. Cost of plants: 4000 ha -1, life > 10 years Schema impiantistico (Fonte: Undedrip Srl)
24 NEW FRONTEERS IN CA SUBIRRIGATION CA-subirrigated Conventional Yield t/ha Irrigation mm N fertilization kg/ha N uptake kg/ha Percolation mm N leaching kg/ha 9 73 CO 2 emission kg/ha
25 Conclusions CA is a valuable option: Increasing of soil fertility (ad SOC, but not everywhere) Reduction of not renevable energy sources usage Reduction of greenhouse gas emission ammonia and nitrate leaching Increase biodiversity but yiedls are in some case lower than in CA
