Abstract

This study highlights the effect of soil conservation measures on physico-chemical properties of soil and maize yield on different slope positions at Learning Laboratory for Agroforestry, UPLB Los Baños, Laguna. The main objective of the study is to assess the physico-chemical properties of soil on a vegetative conservation measure (Hedgerow) and structural conservation measure (Balabag), their maize yield and their interaction at different slope positions. Treatment plots of the experiment was laid out in randomized complete block design with a split plot variation for slope positions with three replications. Each plot had a size of 2 m by 10 m with a total area of 200 sq. m and the experiment lasted for two cropping seasons. All quantitative treatments and maize yield were statistically analyzed using HSD Tukey?s test at 0.05 level of significance. Results showed that there is an observable downward trend of soil physico-chemical properties and the conservation measures used with slope position variation do not have statistical significant changes in soil conservation measure. For corn yield, balabag conservation produced better agronomic yield compared to hedgerow and control plots while nutrient content and uptake of the stover do not have significant differences with each other. The downward trend of physico-chemical properties may link to nutrient loss and nutrient cycling. The soil that was used for the site was worn-out and there are lack of management practices to improve soil fertility. The study should be given a long period of time to accurately observe the conservation effects of the upland conservation systems. It should be also replicated to other locations to ascertain the integrity of the study.
