Application of phosphate solvent microbes and coffee skin compost to increase nutrient uptake of Robusta coffee plants in Andisols

Abstract

Coffee plants need phosphorus nutrients for growth and fertilization in high quantities. Andisol has a very low availability of P. Efforts that can be made to increase the availability of P are by utilizing phosphate solvent microbes and coffee skin compost. The purpose of this study was to obtain the right type of microbial phosphate solvent and organic coffee skin ingredients in increasing the availability and growth of coffee plants in Andisol affected by the eruption of Mt. Sinabung. This study used a factorial randomized block design (RBD) consisting of 3 replications. Factor I: (Microbial Phosphate Solvents) M0 = Without application, M1 = Burkholderia cepacia, M2 = Talaromyces pinophilus, M3 = Burkholderia cepacia + Talaromyces pinophilus. Factor II Organic ingredients of coffee skin compost are K0 = without organic matter, K1 = 75 g, K2 = 150 g, K3 = 225 g. The results of the study showed that B.cepacia + T.Pinophilus + Mycorrhiza (M4) treatment can increase nutrient uptake of N, P and K of plants up to 12.3%, can increase plant uptake of P up to 18.84%, increase uptake of plant K up to 19.53%. The treatment of 225g of coffee husk compost (K3) can increase plant N nutrient uptake by 7.65%, plant P uptake to 26.11% and plant K uptake up to 14.12%. M4K3 application can increase N uptake up to 53.28%, P uptake up to 98.56% and increase K uptake of plants up to 56.45%. in general the best treatment is M4K3.

Improved Coffee Management by Farmers in State Forest Plantations in Indonesia: An Experimental Platform

“…It is theorized that this yield response is due to increased P availability. Research on agricultural soil shows organic fertilizers can increase P availability in Andosol soils, where P is often bounded and immobile, although the mechanism is not clear [40,41].…”

“…The trials currently being undertaken are the first steps in this, but we fully expect the work to develop. Learning from the initial fertilizer trials is, for example, expected to form the basis of an ongoing process to refine and optimize fertilizer applications within the forest system, helping to support the wider understanding of nutrient cycling with Andosols soils [40,41]. Whilst the coffee pruning work, which already closely matches the approach by Dufour et al, [21], can be linked to the work on pest and disease and microclimate data to provide additional insight into the relative role of pruning and microclimate management on pest and disease occurrence purposed by Dufour et al [21].…”

Knowledge Sharing Dalam Budidaya Kopi: Studi Kasus Program Peningkatan Kapasitas Petani LMDH Wana Asri, Kabupaten Kebumen

“…Petani kopi di Desa Kebakalan masih memiliki pengetahuan yang rendah mengenai cara budidaya kopi (Sembiring et al, 2019) dan pengolahan pasca-panen. Setelah mendapatkan bantuan bibit dari perum perhutani dan Dinas 135 Ketahanan Pangan Kabupaten Temanggung, masyarakat memulai menanam bibit kopi di sela-sela tanaman hutan milik Perum Perhutani.…”

Diversity of potassium solving microbes on andisol soil affected by the eruption of Mount Sinabung, North Sumatra, Indonesia

“…Potassium solubilizing fungi are able to increase the available potassium in the soil (Shelobolina et al 2012;Prajapati et al 2012). Talaromyces pinophilus can increase plant nutrient uptake (Sembiring et al 2020a(Sembiring et al , 2020b.…”
