Functional and antimicrobial properties of bignay [Antidesma bunius (L.) Spreng.] extract and its potential as natural preservative in a baked product
The paper discusses several upland farming systems in the Philippines which are based on nutrient recycling and soil conservation. Some are traditional practices developed by farmers themselves, while others have been introduced in modern development programs. Their impact on soil and water loss rates and soil properties are discussed, and compared with those resulting from current farmers' practices.
