“…Low available P is a common problem. [12] explains that the maximum availability of P is found in the pH range between 5.5 -7. The availability of P decreases at a soil pH lower than 5.5 or higher than 7 due to P fixation by acidic or basic cations, at low pH, the availability of P is lower this is because P in the soil is in a fixed form in the form of Al-P, Fe-P, Ca-P, and P-bound [7,13,14] The availability of K is affected by the saturation of Ca + and Al 3+ , in the acid soil reaction, the soil colloid will be saturated with acidic cations (Al 3+ ), while in the alkaline soil reaction, the colloidal soil will be saturated with cations (Ca + ).…”

This study aims to assess the soil quality index (SQI) under the shade of coconut (Cocos nucifera L.) and its relationship to land suitability to provide recommendations for improvement to increase coconut productivity. This research conducted in Kebonagung District, Pacitan District using descriptive survey method. Land Map Units (LMU) are determined by overlaying soil type, land use, slope, and rainfall maps. Determination of survey using purposive sampling with 10 sample and three replications. The samples were analyzed in the laboratory with analysis method Bulk Density (Pycnometer), Porosity (Sample ring), Textures (Pipet), pH (Electrometric), Available P (Olsen method), Available K (NH4Oac 1 N extraction), Kjeldahl (Total N), Base saturation (Ammonium acetate extraction), SOC (Walkey and Black), CEC (Ammonium acetate method). Soil quality assessment was carried out using Principal Component Analysis (PCA) to obtain Minimum Data Sets (MDS). Land suitability was evaluated through the matching method with the conditions for growing coconut plants. The analysis showed that the soil quality index had a significant positive correlation with land suitability (r=0.768, p=0.004). The limiting indicators based on the correlation test were BV, pH, available P, organic C, and CEC. Suggested improvement recommendations include applying land cover crops, dolomite, manure, and balanced P fertilization.

“…The low content of P available in the soil can be caused by parent material from the ground that is poor in P elements and the low range of P in organic matter. [14] explained that P's availability is in the pH range between 5.5 -7. The availability of P will decrease at a pH of more than 5.5 or higher than 7.…”

This study aims to assess the soil fertility index (SFI) under the shade of coffee and its relationship with land suitability to provide recommendations for improving arabica coffee productivity. This research was conducted in Bandar Sub-district, Pacitan District, East Java, using an exploratory, descriptive survey method. Land Map Units (LMU) are determined by overlaying soil type, land use, slope, and rainfall maps. Determination of survey points using purposive sampling with 10 sample points and three replications. The samples were analyzed in the laboratory to determine the soil’s physical, chemical, and biological characteristics. Soil quality assessment was carried out using Principal Component Analysis (PCA) to obtain Minimum Data Sets (MDS). Land suitability was evaluated through the matching method with the conditions for growing arabica coffee. The analysis showed that the soil fetility index had a significant positive correlation with land suitability (r=0.806, p=0.002). The limiting indicators based on the correlation test were SOC, pH, available P, and Base Saturation. Suggested improvement recommendations include applying land cover crops and balanced P fertilization.

“…Adapun KB yang berkaitan erat dengan pH tanah, di mana semakin rendah pH maka semakin rendah KB, begitupun sebaliknya (Firnia, 2018;Syamsiyah & Wicaksono, 2023). Nilai KB pada unit lahan didominasi dengan kriteria rendah sehingga dapat disimpulkan bahwa jerapan lebih banyak diisi oleh kation-kation asam yaitu Al +3 dan H + , apabila kation asam terlalu banyak terutama Al +3 , bisa menjadi racun bagi tanaman.…”

Penelitian ini bertujuan untuk mengetahui status kesuburan tanah pada lahan kering, parameter kesuburan tanah yang menjadi faktor pembatas pada lahan kering dan membuat peta status kesuburan tanah di Kecamatan Ererasa, Kabupaten Bantaeng. Penelitian ini dilaksanakan di Kecamatan Ererasa, Kabupaten Bantaeng, Sulawesi Selatan dan Laboratorium Ilmu Tanah dan Konservasi Lingkungan Fakultas Pertanian Universitas Muslim Indonesia dan Laboratorium Tanah Fakultas Pertanian Universitas Hasanuddin pada Februari–Agustus 2022. Data dari peta penggunaan lahan, peta jenis tanah, peta lereng, dan peta kesuburan tanah dikumpulkan dengan menggunakan teknik penelitian Pusat Penelitian Tanah (PPT) 1995. Kedua peta tersebut disandingkan. Respon tanah (pH), Kapasitas Tukar Kation (KTK) tanah, kejenuhan basa (KB), kandungan fosfor (P), kandungan kalium (K), dan karbon organic (C-Organik) adalah beberapa karakteristik tanah yang dinilai di laboratorium dan semuanya disesuaikan dengan informasi yang diberikan terkait evaluasi kesuburan tanah metode PPT 1995. Data dikumpulkan menggunakan sumber primer dan sekunder, dan kemudian dimodifikasi untuk memenuhi rekomendasi PPT 1995 untuk kesuburan tanah. Hasil penelitian menunjukkan bahwa status kesuburan tanah di Kecamatan Ererasa, Kabupaten Bantaeng berada pada status kriteria rendah hingga sangat rendah. Parameter kesuburan tanah yang menjadi kendala status kesuburan tanah adalah KTK, KB yang didominasi kriteria rendah, dan kandungan P yang juga memiliki kriteria rendah, C-organik dan K dengan kriteria sangat rendah dan pH didominasi oleh kriteria sedikit asam. Daerah penelitian dengan status kesuburan tanah rendah adalah 2.611,92 ha, sedangkan daerah penelitian dengan status kesuburan tanah sangat rendah adalah 72,96 ha.
