Morfologi Dan Kandungan Flavonoid Total Bunga Telang Di Berbagai Ketinggian Tempat Tumbuh Berbeda, Bambang Pujiasmanto, Hawari Hawari, Eddy Triharyanto

Jurnal Kultivasi

AbstrakBunga telang (Clitoria ternatea L) merupakan salah satu tanaman leguminoceae yang memiliki manfaat farmakologis, namun sebagian besar pemanenannya berasal dari alam dan belum dibudidayakan secara luas. Oleh karena itu, perlu diadakan suatu penelitian spesifik terkait morfologi dan kandungan flavonoid bunga telang untuk dijadikan tanaman budidaya serta mengkaji kesesuaian lingkungan untuk budidayanya. Tujuan riset ini untuk mengkaji karakter morfologi dan kandungan flavonoid bunga telang di berbagai ketinggian. Survei dilaksanakan di lokasi berbeda, yaitu dataran rendah (Karangasem, Jeyengan, dan Purwosari) dan dataran tinggi Ngargoyoso, mulai bulan Februari sampai April 2021.  Lokasi survei dipilih dengan metode acak memihak (purpose random sampling) melalui pendekatan …

Estimating Soil Texture By Hand

Natural resources factsheets

Estimating or measuring soil texture provides valuable information about soil properties affecting crop and pasture growth. Soil texture affects the movement and availability of air, nutrients, and water in soil. A simple and quick measure of soil texture is the way a soil feels when manipulated by hand.

The department recommends laboratory testing of soil texture (and other factors) for all critical soil uses, including farm dam construction and claying.

Stocking Rate Guidelines For Rural Small Holdings, Swan Coastal Plain And Darling Scarp And Surrounds, Western Australia

Miscellaneous Publications

Small rural holdings are often owned by people who want to pursue a semi-rural lifestyle but who are inexperienced in land management issues. This can result in landholders stocking their properties with animals at rates higher than the land resources can sustain, leading to degradation problems such as soil erosion, water pollution and damage to vegetation. This document provides information and guidelines to help planners, developers, local authorities and land owners determine the base stocking rates for rural small holdings on the Swan Coastal Plain and Darling Scarp and immediate surrounds. The advice utilises Agriculture Western Australia’s rural stocking rate …

Method For Calibrating An Arduino-Based Soil Moisture Sensor Using Van Genuchten’S Equation, Victorino Bato

The Philippine Agricultural Scientist

Instructions on building a do-it-yourself soil moisture sensor using Arduino microcontrollers abound on the Internet. These do-it-yourself soil moisture sensors are favorite projects by both plant and microcontroller enthusiasts because the parts are affordable and the end product is functional. In the absence of proper calibration, these soil moisture sensors cannot generate usable information on the status of plant-available-water in the soil. This research demonstrates the calibration of an Arduino-based soil moisture sensor using the soil moisture characteristic curve of a clay loam soil. Van Genuchten’s model was used to generate an equation and various parameters specific to the soil. …

Aplikasi Pupuk Organik Dan N, P, K Terhadap Ph Tanah, P-Tersedia, Serapan P, Dan Hasil Padi Hitam (Oryza Sativa L.) Pada Inceptisol, Eso Solihin, Anni Yuniarti, Ayuning Arief Putri

Jurnal Kultivasi

Sari. Padi hitam memiliki khasiat yang baik untuk kesehatan, yang dapat meningkatkan daya tahan tubuh terhadap penyakit, mencegah gangguan fungsi ginjal, mencegah kanker / tumor, dan banyak manfaat lainnya. Dewasa ini, produktivitas padi hitam masih relatif rendah, dengan beberapa penyebabnya adalah degradasi lahan dan ketidakseimbangan nutrisi di tanah. Salah satu ordo tanah yang distribusi secara luas di Indonesia yang dapat digunakan untuk budidaya tanaman adalah Inceptisol. Oleh karena itu, Inceptisols memerlukan penanganan yang tepat, seperti aplikasi pupuk organik dan anorganik yang seimbang. Tujuan dari penelitian ini adalah untuk mengetahui macam pupuk organik dan dosis N, P, K terbaik terhadap pH …

Kompleksitas Pengaruh Temperatur Dan Kelembaban Tanah Terhadap Nilai Ph Tanah Di Perkebunan Jambu Biji Varietas Kristal (Psidium Guajava L.) Bumiaji, Kota Batu, Hidayati Karamina, Ariani Murti, W Fikrinda

Jurnal Kultivasi

Kawasan Bumiaji merupakan kawasan wisata yang berada di Kota Batu. Suhu rata-rata udara mencapai 20 oC menyebabkan Bumiaji menjadi kawasan yang cocok untuk tanaman hortikultura misalnya jambu biji varietas kristal. Tanaman jambu biji varietas kristal pada pemeliharaannya diberikan pupuk berupa pupuk organik maupun pupuk anorganik beserta beberapa pestida untuk menekan peledakan hama dan penyakit tanaman. Usaha-usaha peningkatan hasil produksi diatas ternyata dapat memberikan dampak kurang baik bagi lingkungan sekitar. Pupuk dan pestisida tersebut merupakan sumber pencemaran logam berat. Tujuan dari penelitian ini, yaitu untuk mengkaji bagaimana aspek-aspek seperti temperatu tanah dan kelembaban tanah mampu mempengaruhi nilai pH tanah di perkebunan …

Western Australian Soil Groups - A Diagnostic Key To Identify Soils In Western Australia, Edward Griffin, Dennis Van Gool, Shahab Pathan

Resource management technical reports

The aim of the Western Australian soil groups (WA soil groups) is to classify soils of Western Australia into a limited set using criteria that are easy to recognise in the field. It is a general-purpose classification with a focus on agronomic and rangeland grazing potential. The WA soil groups are designed for WA needs. It complements the Australian Soil Classification (ASC) by grouping the continuum of soils into a limited set of soil types, which simplifies soil variability for generalists, allows soil surveyors to create standardised soil-type legends for mapping products and permits further analyses of spatial data for …

Micro-Topographic Control On Soil Moisture And Ph Dynamics In A Northern Peatland Ecosystem: A Case Study From Saco Heath, Maine, Henry Mahoney

Student Publications

Peatland ecosystems are characterized by complex structural microtopography, prominently featuring elevated hummocks and depressed hollows that establish critical micro-environmental and ecohydrological gradients. This study investigates the influence of micro-topographic positioning on soil moisture and pH dynamics at the Saco Heath Preserve; a raised acid bog located in southern Maine. Data collection was focused entirely within Sphagnum moss, which serve as the dominant vegetative component across multiple structural hummocks and hollows. Using a systematic temporal framework and a robust spatial sampling strategy (n = 100 per micro-habitat) between July 16 and August 16, we quantified physical moisture contents and chemical pH …
