The present work deals with the assessment of the effect of digestate (doses of 220; 150 and 80 kg N ha−1), mineral fertilizer (150 kg N ha−1), and compost application (150 kg N ha−1) on selected indicators of soil environment: (a) soil microbial activity (basal and substrate-induced respiration); (b) plant nutrient content (P, K, Ca, Mg ...
The main objective of the automation project was to change to an environment in which terminal automation, production automation, and the enterprise resource planning (ERP) system form a seamless whole.
INTRODUCTION This document gives a short overview on the control methods that are available or practically used in mineral processing (MP) plants (Hodouin et al. (2001)). A brief description of the chain of processes involved in MP plants is first …
For example, high volume production has high latencies and mass-balancing is particularly difficult. In addition, batch production where the plant's key KPI (referring to OEE) depends on batch cycle times and difficult product mixes is typically found in multi-purpose plants.
Nakhodka Mineral Fertilizer Plant has chosen Haldor Topsoe A/S (Lyngby, Denmark; ) technology for a 5,400 tons-per-day methanol plant near Vladivostok in the Eastern part of Russia. China Chengda Engineering Co., LTD, has …
Mintec mineral processing pilot plant was established in 1980s in Outokumpu city and experienced several changes afterwards, among which was a government decision to transfer the facilities to GTK ...
While the nutritional content of organic fertilizers can be inconsistent, influenced by soil health and climate, mineral fertilizers offer high nutrient concentration and immediate availability. However, as mineral and organic fertilizers complement each other, a comprehensive nutrient program should incorporate both.
The use of minerals that contain fertilizer nutrients in their native state is a very promising approach to reducing emissions associated with the processing chemical industries.
With the exception of C, H, and O, which plants obtain from air and water, plants derive the remaining 14 elements from the soil or through fertilizers, manures, and amendments (Parikh & James 2012).
As the demand for food is increasing worldwide, fertilizers are playing an essential role in improving agricultural productivity. OCI Nitrogen (hereinafter OCI) is a leading producer of mineral fertilizers and the world's largest producer of melamine, which is used to make adhesives and resins for a wide range of applications, such as furniture panels, laminate …

The heavy use of mineral fertilizers causes imbalances in the biological processes that take place in soil. Therefore, it is necessary to develop more effective fertilizers or fertilizer complexes that ensure agricultural productivity and soil conservation. There is currently a lack of knowledge regarding the effectiveness of biologically …
Even though it has thus far reliably fed an exponentially growing human population. The agricultural revolution, which began in the 18th century, allowed yields to increase enormously. It is based on the increasing use of high-yielding varieties, mineral fertilizers and chemical pesticides, on mechanization and large-scale artificial irrigation.
The utilization of plant biostimulants has gained importance as a strategy by which to improve plant productivity and soil health. Two independent trials were conducted across two seasons (2021 and 2023) to evaluate the effects of foliar or soil applications of various commercial organo-mineral fertilizers (Futuroot®, Radicon® Amifort®) with …
INTRODUCTION. As with all chemical process industries, the production of mineral fertilizers gives rise to emissions, which contribute to environmental problems, both globally and locally. Over the last 25 years, much research and expenditure has been …
Plant Automation for Energy-Efficient Mineral Processing. Jocelyn Bouchard, Daniel Sbarbaro and André Desbiens. Abstract Mineral processing is one of the most energy-intensive stages of the overall mining beneficiation chain, with an increasing share of the …
Long-term use of inorganic fertilizers can increase soil acidity, be harmful to the environment, and leaving bad effects on human health. Organic fertilizer application is one of the safer alternatives with numerous benefits, such as supplying nutrients for plant growth. Sunflower is one of the most important grown oilseed crops in the world. …

The use of mineral fertilizers has long been a key tool to offset nutrient outputs and thus achieve increased yields [1,2,3,4]. Fertilizer application is believed to have been responsible for at least 50% increase in crop yield in the 20th century [5,6].
Green Plant Organic Fertilizer Sdn Bhd is a subsidiary company of Havys Oil Mill Sdn Bhd. The company was incorporated in 2010 to focus in processing the industrial wastes from the palm oil mill. As Havys production capacity continues to increase, so does the quantity of industrial wastes.
The compound also has the additional benefit of preventing root rot and maintaining overall plant health. This nitrogen-rich fertilizer is best to use when the crops are also suffering from calcium deficiency. 10. Feather Meal . Feather meal is produced by processing the feather by-products from poultry farms.
