A financial model of smallholder forestry seedling nursery on Leyte Island has been developed as a contribution to the ACIAR project ASEM/2006/091 – Enhancing tree seedling supply via economic and policy changes in the Philippines nursery sector. Two versions of this model have been developed – one for a best management practice nursery and one for a representative smallholder nursery. This paper describes the data collection, and model development and implementation. Some implications are drawn for policy development concerning adoption of best management practice in smallholder nurseries. Possibilities for further development and application of the seedling nursery model are discussed.

High quality tree seedlings are critical factors which determine the success of tree plantation projects. To produce high quality seedlings, nursery operators need to apply appropriate nursery management practices. However, tree seedlings produced by nursery operators in the Philippines are often of low quality, due in part to weak organization in the nursery sector and lack of skills in the application of nursery practices among nursery operators. The Q-seedling Project or Seedling Enhancement Project funded by the Australian Centre for International Agricultural Research (ACIAR) is being implemented in Leyte and Northern Mindanao to remedy this skills gap. The project includes a communication component to promote widespread adoption of best management practice in forest nurseries. Following the strategic communication approach, information dissemination activities in the project are based on the needs of the target users. Training workshops have been held on producing high quality seedlings. Also, communication materials have been developed for nursery operations, including a training guide, videos instructional posters on Q-seedling production technologies, and a jingle about Q-seedlings. This paper describes the design and use of these communication materials.

Abstract. Contemporary agriculture is shifting from a single-goal to a multi-goal strategy, which in turn requires choosing best management practice (BMP) based on an assessment of the biogeochemical effects of management alternatives. The bottleneck is the capacity of predicting the simultaneous effects of different management practice scenarios on multiple goals and choosing BMP among scenarios. The denitrification–decomposition (DNDC) model may provide an opportunity to solve this problem. We validated the DNDC model (version 95) using the observations of soil moisture and temperature, crop yields, aboveground biomass and fluxes of net ecosystem exchange of carbon dioxide, methane, nitrous oxide (N2O), nitric oxide (NO) and ammonia (NH3) from a wheat–maize cropping site in northern China. The model performed well for these variables. Then we used this model to simulate the effects of management practices on the goal variables of crop yields, NO emission, nitrate leaching, NH3 volatilization and net emission of greenhouse gases in the ecosystem (NEGE). Results showed that no-till and straw-incorporated practices had beneficial effects on crop yields and NEGE. Use of nitrification inhibitors decreased nitrate leaching and N2O and NO emissions, but they significantly increased NH3 volatilization. Irrigation based on crop demand significantly increased crop yield and decreased nitrate leaching and NH3 volatilization. Crop yields were hardly decreased if nitrogen dose was reduced by 15% or irrigation water amount was reduced by 25%. Two methods were used to identify BMP and resulted in the same BMP, which adopted the current crop cultivar, field operation schedules and full straw incorporation and applied nitrogen and irrigation water at 15 and 25% lower rates, respectively, than the current use. Our study indicates that the DNDC model can be used as a tool to assess biogeochemical effects of management alternatives and identify BMP.
