Human Environment Cropland per household (ha) 10,000 Implementation activities, inputs and costs Establishment activities 1. No tillage machinery 2. Subsoiling every 5 years Maintenance/recurrent activities 1. Herbicide application 2. Seeding 3. Fertilization Land user: Individual privileged small scale land users, mainly men Population density: 10-50 persons/km 2 Annual population growth: < 0.5% Land ownership: individual, titled Land use rights: individual Water use rights: individual Relative level of wealth: mainly poor land users, which own 60% of the land Remarks: Availability of machinery is the most determining factor affecting the costs. SLM Technology: No tillage with subsoiling, Chile DESIRE – WOCAT 2012 Importance of off-farm income: 10-50% of all income: Access to service and infrastructure: low: drinking water and sanitation; moderate: health, education, technical assistance, employment, energy, roads & transport, financial services Market orientation: mixed (subsistence and commercial) Technical drawing Photo of subsoiling drill (photo by Carlos Ruiz). The subsoiler is a 3-point chisel plough that breaks up the soil hardpan to a depth of 30 to 50 cm Establishment inputs and costs per ha Inputs Costs (US$) % met by land user Labour 50 100 Equipment - renting seeder machine - renting subsoiling machine 60 70 TOTAL 180 28 Maintenance/recurrent inputs and costs per ha per year Inputs Costs (US$) % met by land user Labour Equipment 30 100 - renting seeder machine Agricultural 60 0 - seeds 50 0 - fertilizer 174 0 - herbicide 20 0 TOTAL 334 9 0 0 79
Assessment Impacts of the Technology Production and socio-economic benefits Production and socio-economic disadvantages increased crop yield decreased labour constraints decreased workload simplified farm operations reduced risk of production failure increased farm income increased expenses on agricultural inputs Socio-cultural benefits Socio-cultural disadvantages improved conservation / erosion knowledge improved food security /self sufficiency community institution strengthening Ecological benefits Ecological disadvantages improved soil cover increased biomass / above ground C increased nutrient cycling recharge reduced soil loss reduced soil crusting / sealing reduced soil compaction increased soil organic matter / below ground C Off-site benefits Off-site disadvantages reduced surface runoff increased water availability Contribution to human well-being/livelihoods improved tillage improves crop yields and thus household income increases Benefits/costs according to land user Acceptance/adoption: Benefits compared with costs short-term: long-term: Establishment positive positive Maintenance/recurrent positive positive The adoption of the technology has been subject to the establishment of transfer programmes with smallholder farmers. In particular, in two communes of the “secano interior” (Ninhue and Yumbel), 100% of the families who were part of the technology transfer programme on no tillage adopted the technology. In terms of the area covered, the programme covered 1000 ha and 35% of the area adopted no tillage. Only a few land user families have implemented the technology voluntarily. There is no trend towards (growing) spontaneous adoption of the technology. Concluding statements Strengths and how to sustain/improve Weaknesses and how to overcome No tillage preceded by subsoiling as part of the incentive programme for the recovery of degraded soils managed by the Agriculture and Livestock Service (SAG) Adjusting incentives according to timing of the expenses and investments and also conditioning incentives to the adoption of the technologies The availability of machines is the main obstacle for adopting zero tillage and subsoiling To create and promote small companies of agricultural machinery, managed by farmers themselves. Two examples already exist in the counties of San Carlos and Ninhue. Key reference(s): Del Pozo, A., Del Canto, P. 1999. Areas agroclimaticas y sistemasproductivos en la VII y VIII Región.
