Trees and soil management practices (i.e., pruning and fertilization) are essential in maintaining the soil fertility and coffee yield sustainability in coffee agroforestry systems. This study aimed to evaluate the impact of trees and soil management practices on the soil nutrient status within coffee-based agroforestry systems. The research was conducted in coffee agroforestry systems within Universitas Brawijaya Forest (UB Forest) from January to July 2023. The experiment was performed using a factorial randomized block design with three factors, including: 1) pruning of coffee (T1: pruned coffee, T2: unpruned coffee), 2) Fertilizer type (O: organic fertilizer, A: inorganic fertilizer, M:50% organic + 50% inorganic), and 3) Fertilizer dosage (D1: Farmer‘s dose, D2: recommended doses from the Indonesian Coffee and Cacao Research Institute (ICCRI), D3: Dosage from nutrient replacement), totaling 18 treatments with four replications of each. The soil sample was collected at topsoil (20 cm soil depth) around 50 cm from the coffee stem at the beginning of the research and six months after fertilization. The study revealed that tree management affected (p>0.05) soil nutrient status (i.e., soil total N and available P), where pruned coffee management increased soil nutrient status by 2.02 to 4.53 times compared to the unpruned coffee plot. Types and doses of fertilizer significantly affected soil pH (P < 0.05), where the application of organic fertilizer with the recommended dose (OD2) had the highest soil pH. The correlation analysis showed that soil nutrients correlated to coffee yield. The principal component analysis shows that pruned coffee combined with mixed fertilizer at the farmer‘s dose (T1MD1) is closely related to coffee production.

Nutrient management in coffee-based agroforestry systems plays a critical role in soil nitrogen (N) cycling, but has not been well documented. The objective of this study was to evaluate the effect of coffee canopy management and fertilization on soil N dynamics. This study used a randomized complete block design (2 × 3 × 2) with four replications. There were three factors: 1) coffee canopy management (T1: Pruned, T2: Unpruned), 2) fertilizer type (O: Organic, I: Inorganic; M: 50% Organic + 50% Inorganic), and 3) fertilizer dose (D1: low, D2: medium, D3: high). Soil N dynamic indicators (i.e., total N, ammonium (NH4+), nitrate (NO3−), net N-NH4+, net N-NO3−, soil microbial biomass N) were measured at two soil sampling depths (0–20 cm and 20–40 cm). Results showed that pruning increased soil total N and microbial biomass N (MBN) by 10–56% relative to unpruned coffee trees. In contrast, the unpruned coffee canopy had 15–345% higher NH4+, NO3−, net N-NH4+, net N-NO3−, and microbial biomass N concentration than pruned coffee. Mixed fertilizer application increased NO3− and net N-NH4+ accumulation by 5–15% relative to inorganic and organic fertilizers. In addition, medium to high dose fertilization led to a 19–86% higher net N-NO3− concentration and microbial biomass N as compared to low dose fertilization. The treatment of no pruning and mixed fertilizer at low to medium doses was the optimal management strategy to maintain soil available N, while pruning combined with organic fertilizer has the potential to improve soil total N and MBN.

The agroforestry and intercropping systems are recognized as important options for greenhouse gas mitigation. The primary objective of this study was to assess the impacts of land use change from Orange (O) monoculture to Coffee-Orange (CO) intercropping and Coffee-Forest (CF) agroforest systems, implemented 20 years ago, on soil properties at three different soil depth layers (0–10 cm, 10–20 cm, 20–30 cm), with a particular focus on microbial biomass carbon (MBC) and soil organic carbon (SOC) levels. Although there were no changes in most of the soil’s physical properties, the soil’s chemical properties varied significantly across different land use types. SOC was higher in CF and CO systems compared to the O system; however, only in the CO system was the SOC incorporated evenly across all depths. Regression analysis showed that, in the CO system, microbial biomass carbon increased significantly, suggesting that these systems are more promising for carbon sequestration. The low pH and phosphorus values in the agroforest system were identified as limiting factors for microbial biomass enhancement. Importantly, the integration of coffee into orange cultivation not only enhances economic benefits but also contributes to long-term carbon sequestration by increasing SOC in deeper soil layers.
