Intercropping expressed in terms of Land Equivalent Ratio (LER) which shows the ratio of the area under sole cropping to the area under intercropping needed to give equal amounts of yield at the same management level, it is the sum of the fractions of the intercropped yields divided by the sole-crop yields.
When nitrogen fertilizer is restricted in supply, biological nitrogen fixation is an important source of nitrogen in legume-cereal cropping systems.
The easiest way to incorporate cover
cropping is the half-and-half strategy: I dedicate every other garden bed to cover crops for an entire year.
The
cropping systems were evaluated for their productivity and to assess their effect on the soil organic carbon contents and available soil NPK.
Crop rotations provide several advantages compared to continuous
cropping including weed control, disease and insect control, rotation effects, and reduced risks.
I imagine there was a time when cover
cropping was considered conventional.
Not only will they require hard-to-get spare parts and petroleum-based fuels, but they were developed for different soils and
cropping patterns.
Crop rotation has many agronomic economic and environmental benefits compared to monoculture
cropping.
The expansion of
cropping into the Cerrados is in part due to varieties and production practices developed by the organization.
Each year, we take 10 to 12 farmers from one of four regions (Southeast, Southwest, West and Midsouth) to another region to learn about differences in cotton mechanisms and
cropping," says Ed Cherry, FMC Corp.
Despite a dramatic shift in farm numbers and
cropping patterns, the remaining farmers are highly committed, knowledgeable and extremely adaptive.
