Soil is the result of the transformation of minerals and organic matter from the surface to a certain depth. This process is influenced by various genetic and environmental factors, such as the properties of the parent material, climatic conditions, interactions with living organisms, topography, and changes that occur over a long period of time. This study aims to analyze the chemical properties of three different soil types—red soil, humus soil, and limestone soil—to understand their implications for soil management and agricultural productivity. The analysis was conducted at the Soil and Water Laboratory of UPT Agribusiness Development Malang from December 2023 to April 2024. The parameters tested included pH, P₂O₅ content, nitrogen, and K₂O. The results showed that limestone soil had the highest pH, phosphorus, and potassium values compared to red and humus soils, while all three types of soil had very low nitrogen content. This study highlights the importance of proper soil management to improve soil fertility and agricultural productivity.

Vertisols contain clay minerals that expand significantly during the rainy season and shrink during the dry season. This condition causes changes in the availability of water and soil ions. This study aimed to examine the effect of adding organic matter (OM) and sand on changes in vertisols and plant growth. The study was conducted using a factorial Randomized Block Design (RBD). The first factor was 5 kinds of OM: control (B0), 15 tons of banana peel compost ha⁻¹ + cow dung (10:1) (B1), 15 tons of leaf litter compost ha⁻¹ (B2), 15 tons of water hyacinth compost ha⁻¹ + cow dung (1:1) (B3), and 1 ton of biochar ha⁻¹ (B4). The second factor was the provision of sand as much as 3 level, namely: 0% (P0), 20% (P1), and 40% (P2). Each treatment combination was repeated 3 times. Sweet corn was used as a growth indicator. The observed soil chemical parameters were soil pH, organic C, NH₄⁺ and NO₃⁻, and Cation Exchange Capacity (CEC) using standard methods. Leaf area was measured using the Arnon method. The results showed providing banana peel compost + cow dung with 40% sand increased the best NO₃⁻ and soil pH levels. The highest soil C-organic content was found in the treatment with aloe vera compost + cow dung and 0% sand. The best leaf area and plant chlorophyll levels were achieved using banana peel compost + cow dung with 20% sand.

Degraded land affects almost all ecosystems and can harm the progress and quality of human life, so it needs attention. Saline soil is a land degradation with high salt content that causes toxic effects, increases root osmotic pressure, and inhibits plant growth. One solution is using organic mulch processed into biogeotextiles because it can provide solutions for erosion control and soil stabilization while minimizing negative impacts on the ecosystem. This research was conducted from May to August 2023 in the experimental garden of the Faculty of Agriculture UPN ‘Veteran’ East Java. This study used a group randomized design with one factor, the type of geotextile material consisting of reed grass (RG), straw (ST), pandanus odorifer (PO), and sugarcane bagasse (SB). This research was conducted with a litterbox of 20x20 cm filled with 100 g of biogeotextile material. The results obtained show that pandanus odorifer biogeotextile material is the best biogeotextile material because it can last a long time on the soil surface, but can still be adequately mineralized, according to the results obtained, reducing the C/N ratio and C-Organic but increasing total nitrogen. Decomposition is closely related to the materials’ quality rather than external factors. The quality of the material, namely lignin, organic carbon, C/N ratio, and nitrogen, influences the decomposition process. Furthermore, this technology can be applied to improve soil productivity and to keep soil healthy.

Kawasan Kopirejo, yang terletak di Desa Bambang, Kecamatan Wajak, Kabupaten Malang, merupakan daerah pasca erupsi Gunung Semeru yang sedang dikembangkan sebagai desa wisata dengan komoditas utama kopi dan durian. Wilayah ini memiliki karakteristik tanah dominan berpasir dan topografi yang bervariasi, dengan risiko erosi yang cukup tinggi. Dalam upaya mendukung pengelolaan lahan secara berkelanjutan, teknologi drone digunakan sebagai alat monitoring kondisi fisiografi lahan secara real-time.Pengabdian masyarakat ini dilakukan melalui pendekatan pemetaan partisipatif, yang mengintegrasikan data hasil observasi lapangan dengan pemetaan drone beresolusi tinggi. Hasil pemetaan menunjukkan bahwa kondisi biofisik lahan mempengaruhi produktivitas tanaman kopi dan durian, serta perlunya strategi konservasi yang sesuai. Pemanfaatan drone terbukti efektif dalam memberikan informasi spasial mengenai kemiringan lereng, tutupan lahan, serta perubahan kondisi tanah pasca erosi.Implementasi teknologi drone diharapkan dapat meningkatkan pengelolaan kebun kopi rakyat, memperkuat upaya revegetasi, serta mengoptimalkan pengembangan desa wisata Kopirejo secara sosial-ekonomi dan agroekosistem. Integrasi antara akademisi, masyarakat, dan pemerintah menjadi kunci keberlanjutan program ini.

Captan is a fungicide that inhibits the growth of fungi such as Alternaria porri. This fungicide is non-systemic, forming a layer on the surface of leaves and fruit. The continuous use of captan fungicides can leave residues in the environment, especially in soil. One technique to reduce captan fungicide residues is bioremediation. Bioremediation is a way to remove fungicide residues by utilizing microorganisms. The purpose of the study was to obtain yeasts in land polluted with residues of fungicides made from active captan, knowing yeasts that are adaptive to various fungicide concentrations and have the potential to reduce the toxicity of fungicides made from active captan. This study includes soil sampling, isolation and characterization of yeasts morphologically and molecularly, yeast adaptation tests to fungicides, and degradation tests using a complete randomized design. In the adaptation test, all yeasts were able to grow on media added with various concentrations of fungicide product recommendations. Molecular identification of yeast includes DNA isolation, DNA amplification, PCR product sequencing, and molecular data analysis. In the treatment with the addition of yeast, the largest average diameter of A. porri on the seventh day of observation was in the treatment with the addition of W. anomalus and W. onychis yeast. The yeast with the highest ability to degrade fungicides containing the active ingredient captan is W. onychis.

One of the national strategic foodstuffs is maize, whose production can still be increased because the actual yield in the lower than the potential yield. Problems that often arise is low fertility, especially nutrients N, P, and K. The aims of this research is to know the effect of NPK 16:16:16 fertilizer application on the growth, production and uptake of corn plants. The research was conducted in Mojokerto rainfed paddy fields with a randomized group design. The treatments given are 8 in the form of different doses of NPK 16:16:16 fertilizer and control in the form of no fertilizer and NPK 15:15:15 according to the recommended dose. Observation parameters observed were soil analysis, number of leaves, plant height, plant dry weight, NPK nutrient uptake and weight of 100 grains. Data analysis used ANOVA f test at 5% level and DMRT further test at 5% level. The application of NPK 16-16-16 fertilizer at 1/4 dose significantly increased the growth of corn plant and nutrient uptake. NPK 16:16:16 fertilizer at 1/2 dose significantly increased production.

Sistem tanam raised bed beralaskan limbah organik diduga berdampak terhadap kecukupan air, nutrisi, dan gas-gas tanah. Tujuan penelitian untuk mengkaji pengaruh variasi ketinggian raised bed terhadap perubahan sifat fisik dan kimia tanah terpilih. Penelitian dilaksanakan pada bulan Juni hingga Agustus 2025 di Jemur Wonosari, Surabaya. Rancangan Acak Kelompok digunakan untuk mengevaluasi perlakuan ketinggian raised bed : 20 cm (P1), 25 cm (P2), dan 30 cm (P3), masing-masing diulang tiga kali. Sampel tanah diambil pada kedalaman 0-20 cm pada setiap raised bed untuk dianalisis nilai pH tanah, EC, dan C-organik tanah. Hasil penelitian menunjukkan bahwa ketinggian raised bed mempengaruhi nilai ciri tanah tersebut. Nilai pH tanah berada pada kisaran 7,08–7,63, nilai EC tanah antara 0,594 dS/m dan 0,402 dS/m, dan kandungan C organik antara 1,09% dan 0,6%. Kandungan C organik berbanding terbalik dengan EC tanah. Bedengan yang ditinggikan optimal pada ketinggian 25 cm karena dapat menjaga kelembapan, aerasi, dan mendukung dekomposisi bahan organik yang baik.
