P status of Andisol and Its correlation with P content of Arabica coffee leaves in Bener Meriah District

Abstract

Bener Meriah district is one of the arabica coffee producing regions in Indonesia with an average production of 700-800 kg ha−1 year−1. Most of arabica coffee in this area are grown in Andisol. This study aims to determine the P status of Andisol, namely P-available, P-total, P-retention, P content of arabica coffee leaves and the correlation between soil P-available and P content of arabica coffee leaves in Bener Meriah district. This research was conducted using survey methods. The observed parameters were made on Andisol planted with arabica coffee which is located at an altitude of 1,200-1,400 m above mean sea level (AMSL) at slopes 0-3, 3-8, 8-15, 15-30, and >30% respectively. The results showed that Andisol Bener Meriah has a P-available ranging from 0.3 to 12.81 ppm (very low-high). Most of the Andisol observed (73.33%) had P-available at very low and low levels. Andisol Bener Meriah has a P-total ranging from 159.4 to 1,246.7 ppm (low-very-high). Most of the Andisol observed (73.33%) have P-total at moderate, high and very high levels. Andisol Bener Meriah has a P-retention ranging from 85.2 to 87.4%. Arabica coffee leaves have P content levels ranging from 0.10% to 0.23%. Most of the arabica coffee leaves (78.57%) were observed have P content at a minimum level.; there is a close relationship between soil P-available with P content of arabica coffee leaves with a value of r = 0.97.

Effect of shade tree on nutrient concentration in coffee (Coffea arabica L.) leaves

“…Due to the elevated phosphorus content in the soils of these four regions, coffee was often freed up from high phosphate compounds. The P-available is due to the andisols characteristic with tall P-adsorption, extending from 85.2-87.4% [8], and is overwhelmed by allophane. Allophane holds P up to 97.8%, and the nearness of Al and Fe moreover can tie P [9].…”

“…This study was conducted by observing the coffee branches directly in the field. The observation branches were determined following the method of [16]. In each observation tree, four samples of branches were taken, with the densest branches representing the four wind points.…”

The nutrient content of N, P, K in Andisols and Arabica coffee leaves in Bener Meriah Regency, Indonesia

“…Most of the observation points have very low dan low P-available content even though the P-total of the soil is high. The low P-available is due to the andisols characteristic with high P-adsorption, ranging from 85.2-87.4% [23], and is dominated by allophane. Allophane retains P up to 97.8%, and the presence of Al and Fe in amorphous form also can bind P [18].…”

“…The P nutrient content in arabica coffee leaves ranges from 0.10%-0.23% [23] with 78.57% of the observation points at the minimum conditions due to the low P-availability in the soil location. According to [30], arabica coffee leaves have the optimum P nutrient content in the range of 0.15-0.20%.…”
