Economic Model of Deficit Irrigation II (spreadsheet)
This spreadsheet model calculates the net income for irrigated agricultural production. The model is designed to evaluate the economics of deficit irrigation (irrigation at less than the amount required to produce maximum yield).
Economic Model of Deficit Irrigation
The model calculates net income from a crop on a unit of land based on a quadratic crop water production function, amount of effective precipitation, irrigation efficiency, cost of the irrigation water supply, crop production costs, and revenue from selling the crop. The model includes potential income from leasing out saved irrigation water. All biophysical variables are defined in terms of the relative evapotranspiration. Net income is maximized by optimizing the amount of water consumed by the crop.
SNAP - Soil Nutrient Assessment Program
SNAP (Soil Nutrient Assessment Program) is a web-based tool that provides an estimate of plant-available nutrients that the soil naturally provides.
Data from: Secretome data from Trichoderma reesei and Aspergillus niger cultivated in submerged and sequential fermentation methods
The cultivation procedure and the fungal strain applied for enzyme production may influence levels and profile of the proteins produced. The proteomic analysis data presented here provide critical information to compare proteins secreted by Trichoderma reesei and Aspergillus niger when cultivated through submerged and sequential fermentation processes, using steam-explosion sugarcane bagasse as inducer for enzyme production.
Integrated Farm System Model (IFSM)
The Integrated Farm System Model (IFSM) is a process-based simulation of dairy, beef, and crop farming systems. This whole farm model provides a tool for evaluating the long term performance, economics, and environmental impacts of production systems over many years of weather.
Honey
This file contains the annual report of the number of colonies producing honey, yield per colony, honey production, average price, price by color class and value; honey stocks by state and U.S. The report also notes trends and changes in the honey producing sector, such as percent change in honey prices or quantity of production.
Cost of Pollination
This report includes current and previous year data on cost of pollination for tree fruit, melons, blueberries, vegetables, citrus, and other crops. Data is presented in a price per acre, colonies used, price per colony, and total value of pollination by class and type of fruit.
NUOnet (Nutrient Use and Outcome Network) database
The Nutrient Uptake and Outcomes (NUOnet) database will be able to help establish baselines on nutrient use efficiencies; processes contributing to nutrient losses; and processes contributing to optimal crop yield, nutritional and organoleptic quality. This national database could be used to calculate many different environmental indicators from a comprehensive understanding of nutrient stocks and flows.
