Long-term changes in soil biological activity and other properties of raised beds in Longan orchards.

ABSTRACT:

Introduction

The Longan fruit tree of the Vietnam Mekong Delta is grown in raised beds to improve water drainage during the rainy season and can live as long as 100 years.

Objective

This research explores the extent to which the soil microorganisms as well as soil physical and chemical properties of these raised beds degrade over a period of 60 years under traditional management practices.

Materials and methods

Raised bed topsoil samples at depths of 0-20 cm were obtained from four different Longan orchards raised bed age groups: group 1) 15-25 years (L1-L5); group 2) 26-37 years (L6-L10); group 3) 38-45 years (L11-L15); and group 4) 46-60 years. Soil biological properties were tested for nitrogen-fixing bacteria, phosphorus solubilizing bacteria, potassium solubilizi
