Their protection efficacies varied across different types of croplands.
The experiments were carried out on a different type of croplands (i.e. soybean (Glycine max (L).
Instead, the types and proportions of cropland habitat mattered.
Eighteen watersheds were located in the Central Irregular Plains (CIP), characterized by irregular topography, loam soils, and a variety of land use types, including cropland agriculture, tallgrass prairie, and oak-hickory forests.
cThe wetland is dropped because conversion of this type of land to cropland is prohibited in many countries.
However, few studies have examined the effect of cropland abandonment on soil C and N sequestration in various land-use types over time.
These heatmaps offer some insight into the distributions of different types of conservation conflict, but the visual interpretation of these heatmaps is sensitive to the density of cropland, and it is subjective.
We examined the presence of pesticides in sediments of 151 wetlands split among the three dominant land use types, Conservation Reserve Program CRPP), cropland, and native prairie, in North and South Dakota in 2011.
Results indicate that: 1) the overall cropland abandonment rates for the CCFP-participating households were lower than those for the non-participants in the years immediately after the implementation of the CCFP, but there was an acceleration of cropland abandonment by the CCFP participants afterwards, leading to the convergence of cropland abandonment rates between the two types of households.
Eight types of land-use (patch type) were identified: cropland, vegetable land, orchard, forested land, residential land, abandoned cultivated land, wasted grassland, and sand land.
