2. SLM技术的说明

2.1 技术简介

技术定义:

Re-introduction of biosolids to improve fertility of mineral soils

2.2 技术的详细说明

说明:

Since 1960, organic amendments in Italy have been the unique source of nutrients for croplands. Only in the last fifty years, mineral inputs (e.g. nitrogen, phosphorus) have achieved great importance to supply the increasing nutrient needs of cropping systems, although their use do not replace the whole benefits that organic matter provides to the crops and the soil.

Purpose of the Technology: The re-introduction of organic amendments as a fertilisation management strategy is therefore promoted to increase the soil quality and reduce the loss of organic matter, especially in mineral soils. Therefore in Veneto region it was adopted as an agri-environmental measure of the Rural Development Programme (RDP) 2007-2013 to extend sustainable land management.

Establishment / maintenance activities and inputs: The agricultural production in the Veneto region is somehow divided between a flat area upstream (northern plain), where breeding is a very important agricultural activity and a flat area downstream (southern plain), where most of the grain and soybean production is concentrated. In this context, the low economic value given to organic amendments makes it difficult to move manure for north to south. As a result, the RDP finaced the use of organic inputs throughout the agricultural lands, especially favouring the re-introduction of organic amendments in mineral soils with low organic matter cointent.

Natural / human environment: The soil will benefit from organic amendments input. Particularly, high soil organic matter content will improve nutrient cycling and availability, soil water storage capacity, soil structure stability and finally crop productivity. From an environmental point of view, using organic amenedments istead of mineral inputs as a fertilization strategy will improve the carbon cycle by reducing GHG emissions to the atmosphere and increasing the soil organic carbon (SOC) content.

注释:

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 has 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 SLT.
