Báo cáo nghiên cứu khoa học " IMPROVING CAPABILITY FOR ASSESSING SOIL CONSTRAINTS USING THE SCAMP DECISION SUPPORT SYSTEM "

Xóa đói giảm nghèo nông thôn ở Việt Nam sẽ không thể đạt được trừ khi năng lực của nông dân thông qua lợi nhuận và bền vững hệ thống nông nghiệp được tăng cường thông qua công nghệ và kiến thức sản phẩm. Việt Nam có hiệu quả mạng lưới khuyến nông quốc gia, và mạng này được chấp nhận rộng rãi nông dân như một nguồn thông tin và tư vấn. Tuy nhiên, cán bộ khuyến nông thường thiếu một cơ bản nền khoa học đất làm cho nó khó khăn cho nông dân để có được thông tin về đất bền. | Collaboration for Agriculture and Rural Development CARD Program IMPROVING CAPABILITY FOR ASSESSING SOIL CONSTRAINTS USING THE SCAMP DECISION SUPPORT SYSTEM Project title Improving capability of provincial extensionists for assessing soil constraints to sustainable production through the use of the SCAMP decision support system Project code CARD 009 06 VIE Author s Dr. Phan Thi Cong1 Dr. Philip WMoody2 Project implementing organizations 11nstitute of Agricultural Sciences of Southern Vietnam 2 Queensland Department of Environment and Resource Management Sydney University Australia SUMMARY Rural poverty reduction in Vietnam will not be achieved unless the capacity of farmers to adopt profitable and sustainable agricultural systems is enhanced through technology and knowledge products. Vietnam has an effective national extension network and this network is widely accepted by farmers as a source of information and advice. However agricultural extensionists often lack a basic background in soil science making it difficult for farmers to obtain information on sustainable soil management. The result is one size fits all advice on cropping and tillage management. Fertiliser recommendations follow a recipe book based on the crop without regard to existing levels of soil fertility or inherent soil characteristics. However the key to sustainable and profitable cropping is a soil-specific approach to soil management and nutrient inputs. This CARD project addressed the capacity gap in the soils knowledge of extensionists by providing basic training in soil and fertiliser management. In a previous ACIAR-funded project the decision support package SCAMP - Soil Constraints and Management Package was developed to identify soil constraints from simple field observation of soil features supported by simple field and laboratory chemical analyses. SCAMP uses this soil-specific assessment to develop sustainable practices for soil and nutrient management. In the CARD project SCAMP .
