cropland area

In particular, cropland area increased by 25.5% during this period.

The province accounts for about 1.6% of all cropland area in the nation.

There was a 3% shift in cropland area from the moderate to the low erosion risk class.

Also, cropland area is continually threatened by conversion to urban and other uses.

Cereal and oilseed crops dominate two thirds of the total cropland area.

Mineral soils constitute the majority of cropland areas.

Note: the 2020 projected harvested area onservatively assumes preservation of 1995 cropland area.

SLC polygons appearing in three regions are assumed to have 33.3% of their cropland area within each region.

The C values 2are weighted for the proportion of total cropland area, summerfallow area and hayland areas.

Despite a net would benefit from greater increase of nearly 0.4 million adoption of conservation hectares in cropland area, a A combination of practices.

Despite variable cropland area over the five Census years and some shifts in other crops, only small improvements have occurred in the risk of water erosion.

C cropland area C type of crops grown C livestock number and type 2.

The crop or crop group C value is multiplied by the proportion of total cropland area in the region occupied by the individual crop.

Ecoregion effects were cross-correlated with anthropogenic effects such as percent urban and cropland area in the watershed and population density.

These increases in soil loss are the result of the combined effects of changes in cropland areas and shifts in the types of crops grown.

A in 2001, principally owing to the large area in large increase in cropland area used for alfalfa row crops.

With an initial staff of one, early program emphasis was placed on rebuilding the depleted cropland areas and applying conservation practices to the badly eroded steeper land.

SLC polygons that overlapped two regions are assumed to have 50% of their cropland area in each region for the purpose of calculating weighted erosion rates.

The trend shows a moderate increase in "reduced N2O emissions" because of the increase in cropland area under NT and RT over time.

The total agricultural land area has remained stable since the 1960s but the cropland area has grown as a result of the conversion of rangeland and reduction in summerfallow.

C cropland area C type of crops grown C use of conservation tillage and no-till (direct seeding) C area in summerfallow.

An increase in cropland area and and increases in shifts to lower-cover crops such conservation tillage. as canola, potatoes and soybeans put downward pressure on soil cover change.

Thus, it is impossible at this point to accurately track land transfers between main land uses and determine, for example, the extent to which managed forests are affected by changes in cropland area.

The bulk of the load emanates from sheet and rill erosion in cropland areas, and areal variability in loads can be related to land use and surface soil conditions.

In the determination of one erosion rate for each province, cropland areas and previously-calculated erosion rates for each SLC polygon are used to derive a weighted estimate.
