Примери за crop rotation

• Crop rotation kept soil nutrients high and avoided over-farming. 

• The old forms of crop rotation with fallow periods were often displaced by legume-rotation field-grass agriculture. 

• These practices may include cover crops, manures, compost, crop rotation, intercropping, and biological pest control.

• Furthermore, crop rotation, and particularly no-till, promote diverse invertebrate populations, which play an important role in maintaining nutrient cycling and soil structure.

• On the other hand, organic production techniques, particularly crop rotation, can reduce risk in the longer term.

• Soil samples were collected from the same plots for the duration of one crop rotation cycle.

• But obtaining a certificate required not only that one adopt techniques such as crop rotation, manuring and the building of field contours.

• Therefore, once a candidate crop is identified, it may be many years before the crop is ready to be included in a crop rotation.

• The added fertilizer to the crop rotation is adjusted to allow spring barley to receive fertilizer too.

• Commercial oats are often contaminated with wheat due to crop rotation, although oats prolamins are less toxic.

• The two alternatives include continuous soybean and a crop rotation that includes winter wheat and soybean.

• This study indicated that crop rotation and reduced tillage have a number of positive effects on the ecological sustainability of agroecosystems.

• Farmers will select crops based on the return they get from each crop and other constraints, such as crop rotation, labor, or machine availability.

• The sustainability and productivity of the prevailing rotation are being compared with the sustainability and productivity of an improved high input and intensive crop rotation.

• Subsequent trials were planted on a different patch of land following a pre-set crop rotation plan for each location.

• As a result, a farmer who chooses to implement a long-term diversified crop rotation or other conservation practice assumes all the risks.

• Effect of crop rotation and fertilization on maize and wheat yields and yield stability in a long term experiment.
