Elimination of Demand for the Slashing and Burning of Forests through Maintenance of Soil Fertility (e.g., through crop rotation, irrigation). [Pg.69]

Crop rotation is the keystone of organic cropping systems and its importance is emphasized by all organic crop production standards, not only for its role in crop protection, but also for its contribution to soil fertility. Soil fertility may influence the severity of disease infection or offset its effects by accelerating the build-up of yield before the disease takes its toll. This aspect is considered further in Section 18.4.4. [Pg.401]

Crop rotation is a system where different plants are grown in a defined sequence. The well-designed crop rotation is the basis of the success in organic farming. Continuous monoculture is unacceptable due to the increased pressure of weeds and pathogens and difficulties with maintaining soil fertility. Diversity of crops in... [Pg.384]

What to do Do not overfeed with nitrogen-rich fertilizers. Use a potassium fertilizer if rust is a regular problem. Improve the drainage of soil if necessary. Use a crop rotation. Grow more resistant leek cultivars such as Poristo and Poribleu. Do not overcrowd seedlings. Clear away and compost any diseased plant debris. [Pg.333]

What meaning did the participants derive from the model The resource use dimension was best understood in terms of land use, which was observable in the crop rotations on each farm. Intensive rotations extract more in products sold to markets, while extensive crop rotations favour soil fertility, anticipatory handling of pests, and less nutrient leaching, which is the main environmental problem of Finnish agriculture. Extensive rotations are less risky... [Pg.413]

To protect against pests, organic farmers alternate the crops planted on a particular plot of land. Such crop rotation works fairly well because different crops are damaged by different pests. A pest that thrives on one seasons crop of corn, for example, will do poorly on the next season s crop of alfalfa. For fertilizer, organic farmers rely on compost, shown in Figure 15.29. They also include nitrogen-fixing plants in their crop-rotation schedules. [Pg.542]
