2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Sustainable crop production and residue management under no-tillage to improve soil fertility and increase environmental benefits

2.2 Descripción detallada de la Tecnología

Descripción:

Conservation agriculture (CA) in the Veneto region is characterised by management systems including no-tillage, permanent soil cover and crop rotation. CA has been promoted as an agri-environmental measure of the Rural Development Programme (RDP) by the Veneto region to extend sustainable land management. In spite of being provided by the regional government with subsidies, so far the adoption of CA by the farmers has been very limited since its introduction, amounting less than 1% (ca. 2000 ha) of the total regional cropland area (mainly concentrated in the low Venetian plain).

Purpose of the Technology: CA has been proposed to the farmers with the aim of reducing environmental impacts as well as economic and energetic inputs to the agricultural system. Compared with conventional practices such as soil ploughing, CA is convenient due to the saving of labour and fuel costs, with a direct effect in reducing CO2 emissions into the atmosphere. Limiting the soil disturbance and guaranteeing the continuous soil cover involve both a reduction of water runoff and surface erosion and an increase of soil biodiversity and fertility.

Establishment / maintenance activities and inputs: The main winter crops usually cultivated in the low Venetian plain are wheat, rapeseed and barley, while summer season crops are maize, soybean, sorghum. Generally CA consists of direct sowing on untilled soil using a double-disk opener planter for seed deposition, while after harvesting crop residues are chopped and dispersed to the surface in order to guarantee a mulching effect and a rapid incorporation into the soil. Since application of CA practices consider the permanent soil cover, the main crop is followed by cover crops that are usually graminaceae or brassicaceae. Cover crops are neither fertilized nor treated with pesticides during growing, while their final devitalisation is achieved with non-specific herbicides (e.g. Glyphosate, Glufosinate Ammonium).

Natural / human environment: Advantages of adopting conservation agriculture have been widely demonstrated worldwide and can be classified in economic, agronomic and environmental benefits. From an environmental point of view, the soil system preserves its structure and biodiversity thanks to minimum soil disturbance to the root zone, microorganisms, fungi and macroinvertebrates. Greenhouse gas emissions under conservation agriculture compared to traditional cultivation systems are lower and might offset the gains obtained to mitigate global warming. Due to the recent introduction of the technology in the Veneto region (since mid-2000s), conservation agriculture has shown contrasting results in terms of crop yield since still in a transition period between conventional and conservation agriculture practices.

3.2 Tipo(s) actuales de uso de la tierra donde se aplica la Tecnología

Comentarios:

Major land use problems (compiler’s opinion): Soils in the low Venetian plain of the Veneto region generally suffer from a loss of soil organic matter (SOM) that is strongly affected by their natural texture and climatic conditions. Moreover, in the last 50 years intensive tillage practices contributed to a further SOM decrease, estimated at 0.02-0.58 t/ha/y of carbon.

Major land use problems (land users’ perception): Decrease of productivity, soil compaction. To date, few farmers have adopted voluntarily conservation practices to reduce a decline of soil fertility and SOM content, symptom of poor perception of the problem. Moreover, the low technical know-how causes low yield performances and discouraged farmers to adopt the SLM technology.
