2.1 技术简介

技术定义:

Certified Organic Agriculture (EU standards) with a combination of arable and vegetable crops on sandy loam soils in the Netherlands

2.2 技术的详细说明

说明:

The technology is in this specific case applied on sandy loam soils in the Netherlands. It is not limited to those specific conditions. Organic agriculture could as well be applied on other soil types, and it could be applied in various cropping systems as well. There are no environmental limitations known which would prevent a farmer from applying certified organic agriculture on his farm fields.

The characteristics which a system has to fulfill to be certified organic agriculture are to be found in the standards for organic production in the EU (Council Regulation (EC) No 834/2007). Main points in this standard are: no application of synthetic pesticides and no use of synthetic fertilizer. Next to that, there are certain specifications on how many crops you need to have as a minimum in your rotation etc. The purpose of this technology is a sustainable production in general. The idea behind is, that with more care and attention for your production, without the use of synthetic products, you will have a more sustainable and resilient system.

The major input in organic agriculture is organic manure. Because synthetic fertilizers are not allowed more care and attention is paid to apply the right amount of the right organic fertilizers. In general this leads to higher inputs of organic matter to the soil.

The positive impacts of organic agriculture are:
- better general soil quality (more organic matter, better structure, higher fertility, more soil life, more diverse soil life)
- better water holding capacity
- reduced nitrate leaching to the groundwater
- good economic impact (with the label 'organic' farmers can sell their products for a higher price)

Organic agriculture (compared to conventional) also has a negative impact: yields are in general up to 20% lower than conventional production. This yield reduction is mainly caused by pests and diseases, because no synthetic pesticides are allowed, the control of many diseases and pests is not possible.

Land users like this technique because it is actually more than just an application of a technique, it is a way of farming. Organic farming calls upon the craftmanship of the farmers. They like it because they know they are contributing to a more sustainable farming system. Farmers may dislike it because it is complicated to obtain the same yields as with conventional agriculture, and because it is not yet possible to control all pests and diseases.

4.4 技术建立所需要的费用和投入

注释:

The costs for establishing organic agriculture are hard to estimate, it depends on the farm specific situation. Anyway, there will be a need to adapt machinery for the weed control. there will be a loss (in turnover and profitability) in the conversion period, because crops grown in this period are organically managed, but cannot yet be sold as organic.
