The objectives of this research were to study: 1) personal information. 2) agricultural extension
method. 3) knowledge and utilization of site-specific nutrient management technology. 4) problems and
suggestions of farmers. Data were collected by interview schedule with 158 rice farmers in Si Mahosot

about technology at a high level and got information from personal media. Liaise between agricultural
extension officers and farmer was moderate. Farmers’ training on technology was rated at a low level.

Farmers used soil series map of Land Development Department to examine the soil series was 69.6
percentage, but do not used soil test kits for the analysis of soil nutrients was 55.1 percentage and do not
use N-P-K fertilizer material for mixing chemical fertilizer as recommended by the SIMRICE program was
52.5 percentage. The most common problem was rare and expensive fertilizer. The suggestions was a
mixed fertilizer as ready-made formula and support soil test kit for farmers.
