Abstract
Nutrient availability plays a crucial role in determining agricultural production and effectiveness. Recent studies have revealed that a considerable number of Indian soils suffer from deficiencies in vital nutrients, primarily due to the excessive extraction of nutrients by crops in comparison to the minimal nutrient supplementation from manures and fertilizers. The present study is an attempt to evaluate the fertility status of Aquilaria malaccensis based homestead plantation system in Golaghat, Jorhat and Hojai districts of Assam. Total of 9 different Aquilaria malaccensis based homestead plantation systems has been selected for the study. Soils were collected for two consecutive years from 2020 -2022 for different seasons at three different depths, i.e. 0-10, 10-20 and 20-30 cm. SOC was medium to high ranging between 1.51% -1.65 percent. Among the nutrients, available N was found to be low to medium ranging between 208.7 kg ha-1 and 246.2 kg ha-1. Available P was found to be low ranging between 6.63 kg ha-1 - 9.41 kg ha-1. Similarly, available K was found to be medium level ranging between 139.2 kg ha-1 -161.7 kg ha-1. Hence it is hoped that the current study will assist stakeholders and policymakers in implementing site-specific nutrient management practices.
