Research Grants:
At both Penn State and Colorado State, funds have been obtained from a wide variety of public and private sources. Much of this has been in the form of multiple small grants and in-kind support from agricultural commodity organizations and foundations. Major specific grants include:
$900,000 from National Science Foundation Academic Research Infrastructure Program for "Renovation of Greenhouses for Plant Science Research", prepared with 2 others (with the rationale that many faculty programs would benefit) and matched by state and university funds.
$240,000 per year CSRS Special Grant has been awarded to Penn State to study "Controlled Environment Production systems" for horticultural crops in Pa., beginning in 1991-92. (I prepared brief proposal, the funds were allocated via political processes). Funding has been continued and enables us to support our strategic thrust on water/nutrient management for intensive cropping systems.
$1.2 million from Pa. Dept. of Agriculture, "A Research Program to Increase Profitability by Reducing Postharvest Loss of Fruits and Vegetables", 1989-1993, with 4 others. (Subsequent political support from industry permitted establishment of permanent program).
