Penelitian ini bertujuan mengukur kadar kromium…
Grain consists of seeds encased in husks that form grains. The quality of grain can be seen from rice cultivation activities depending on the planting process, such as the use of fertilizers, soil quality, and water polluted by industrial waste that can potentially pollute hazardous materials for human health. The purpose of this study was to determine the metal content of Zinc (Zn), Copper (Cu…
Increasing agricultural productivity is currently experiencing many obstacles. Continued use of fertilizers can lead to high fertilizer residues in the soil as well as increased levels of metals such as Cu. Copper is a microelement that plants need in small amounts and becomes harmful at higher concentrations. The purpose of this study was to measure copper levels in the roots and plants of ric…
Salah satu mikronutrien yang penting untuk pertumbuhan dan perkembangan tanaman padi (Oryza sativa L.) adalah seng (Zn). Kekurangan Zn dapat menghambat pertumbuhan, mengurangi hasil panen, serta menurunkan kualitas gabah., meski begitu seng (Zn) hanya diperlukan dalam jumlah yang relatif kecil dapat menjadi berbahaya apabila melebihi ambang batas. Ketersediaan seng (Zn) juga dipengaruhi oleh pe…
The Arboretum of the Faculty of Agriculture, Sriwijaya University was identified as having a distribution of peatlands in it. This research aims to determine the distribution of peatlands in the Arboretum and the characteristics of the peatlands, namely; thickness, maturity, water level, and topography whose data is presented in map form. The method used is a terrestrial survey method, sampling…
Pertambangan merupakan salah satu kegiatan yang dapat menyebabkan suatu lahan mengalami degradasi khususnya pada sifat fisik tanah. Karakteristik sifat fisik tanah yang umumnya terdapat pada lahan pasca tambang timah adalah tanahnya padat dan susah untuk diolah, sifat fisik tanah seperti struktur, tekstur, porositas, dan bulk density yang tidak mendukung, sehingga mengganggu perkembangan sistem…
Phosphorus (P) is an essential macronutrient that plays a critical role in plant growth. Its availability in the soil is frequently limited, particularly in acidic soils such as tidal swamplands. This study aimed to analyze the status of Total-P and Available-P and their relationships with the chemical properties of tidal swamp soils under different Cropping Intensities in Telang Makmur Village…
Peat is a type of wetland formed from the accumulation of decomposed dead vegetation. Peat has a high organic C and N content due to its high organic matter content. The purpose of this study was to examine the relationship between organic C, total N, and the C/N ratio with water table height in peat. The research was conducted at PT. Kelantan Sakti, on productive and unproductive land, using a…
This study aimed to determine copper (Cu) content in Andisol soil cultivated with Chinese cabbage (Brassica pekinensis L.) in Dempo Makmur Subdistrict, North Pagar Alam District, Pagar Alam City, and to analyze the relationship between soil chemical properties and Cu availability. The research used a survey method with purposive sampling at a soil depth of 0–30 cm. A total of 25 individual sa…
Tidal swamp land has several constraints, including high soil acidity, fluctuating water levels,and low potassium (K) availability, which can affect rice productivity. This study aimed to determine the potassium status and site-specific K fertilization recommendations for rice cultivated on tidal swamp land in Mulya Sari Village, Tanjung Lago District, Banyuasin Regency. The study was conducted…
This study aimed to determine the effect of microbial liquid organic fertilizer (LOF) on the chemical properties of peat soil as well as the growth and yield of upland water spinach (Ipomoea reptans Poir.).
