Intensification and extensification as used here refer to increased or decreased capital inputs and productivity per land unit (Moritz et al. 2009).
The observed relationship between DIN flux and chlorophyll was consistent with ship-based observations of a linkage between riverine nutrient inputs and productivity.
The method used in the validation exercise requires fewer assumptions about staff inputs and productivity, does not specifically detail equipment and depreciation, and includes facility estimates.
EC, OM, slope and curvature were used as input variables, and productivity was set as an output variable.
Experiments with a split-split-plot design were conducted at IRRI and PhilRice experiment stations in the 2009 DS, 2009 WS, and 2010 DS to assess the performance of rice in terms of crop growth, grain yield, water input, and water productivity as affected by seedbed management variables such as (1) seedbed seeding rate (SR), (2) seedling age (SA), and (3) seedbed fertilizer management (F).
The relationship between solar energy input and community productivity is a fundamental subject of ecological inquiry, as is the relative abundance of various species.
This is because conventional methods focused narrowly on inputs, yields and productivity.
The temporal correspondence suggests that the effects of watershed activities on nitrate flux were not limited to the spring period of high streamflows, high nutrient inputs, and high productivity, but rather were sustained throughout the year.
SA significantly affected grain yield, total water input, and total water productivity.
"We're successfully managing higher input costs through pricing and productivity," she said, "and we're well-positioned to continue our momentum and take the next step in our transformation".
The energy input, energy productivity and net return of 2 weeks ponding were 9.6, 5.7 and 20.9% higher than one week ponding, respectively.
