Sugar industry press mud as alternate organic fertiliser source
Organic materials are added to soil for improving soil physico-chemical properties. In the present study different doses of press mud along with NPK were applied to wheat crop in pot and field experiments. The increasing levels of press mud application improved soil physical conditions like increase in total porosity and reduced bulk density. Organic matter content, NPK, Fe, Mn, Zn and Cu content ...

Project - Stone Columns for Ground Improvement at Tank Farm in Thailand
This challenging project was carried out in in the area of Map Tha Phut where Thailand´s largest industrial park is located. CeTeau´s scope of work included the ground improvement with stone columns under the footprint of full storage tanks. We installed a total of 2,605 stone columns with an installation depth varying from 6.5 to 12 meters. The improved soil enabled the tank farm to ...

In-situ soil moisture conservation: utilisation and management of rainwater for crop production
The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally cultivated fields. ...

Label policies, marketing strategies and technical developements of compost market in the European countries
Traditionally the use of soil improvers in agriculture is aimed at the restoration of the organic substance removed from the agro-ecosystem by crops. The addition of humus, as replacement for the portion gradually mineralised by the micro-organisms of the soil, leads to the conservation of its fertility under many point of view: physical (e.g. porosity, drainage, aeration), chemical (availability ...

How to maintain soil fertility
In order to maintain soil fertility, some low-yield soil (acid soil, alkali soil and salt soil), chemical improvers and irrigation should be used to improve, remove obstacles and improve the fertility level. In addition, reasonable cultivation and rotation should be carried out to regulate the nutrients and water in the soil and prevent some nutrient deficiency and water vapor imbalance. 1. ...

Recent advances on endophytic fungi optimising soil environment
Plants encounter a plethora of conditions in the soil that are either deleterious, neutral, or beneficial to plant growth. Endophyic fungi living in plant organs have a symbiotic relationship with their hosts. In the past, many studies focused on the interactions between plants and endophytic fungi. However, in natural environment, the interactions among plant, endophytic fungi and soil are more ...

Compost based products: history, recent activities, chances
The amount of compost originating from source separated organic household waste collection in Germany is still increasing. At the end of the year 1997, app. 3.0 to 3.5 millions Mg fresh matter of non-mature and mature compost were produced in 515 composting plants with an input of respectively more than 1.000 Mg organic waste per year in Germany. According to Mellen (1998) an estimated 27% of the ...

Soil microbial community change and recovery after one-time tillage of continuous no-till
Continuous no-till (NT) results in soil improvements, primarily in the surface 5 cm of soil. One-time tillage may improve NT systems by inverting surface soil with less improved deeper soil. Research was conducted to determine the change in abundance of soil microbial groups after a one-time tillage of NT and their recovery dynamics. Experiments were conducted under rainfed corn (Zea mays L.) or ...

On-farm evaluation of the improved soil nmin–based nitrogen management for summer maize in North China plain
The improved soil Nmin–based N management is a promising approach to precision N management, which determines the optimum side-dress N rates based on N target values and measured soil nitrate N content in the root soil layer at different growth stages. A total of 148 on-farm N-response experiments, in seven key summer maize (Zea mays L.) production regions of North China Plain (NCP) from 2003 to ...

What is `Learn About Composting Day`?
Taking place annually on 29th May, ‘Learn About Composting Day’ is all about getting to know how food waste can be converted into a valuable soil improver – and it’s a day, and purpose, very close to our hearts, here at Tidy ...

Function and production of carbon based fertilizer
Function of carbon based fertilizer Organic carbon fertilizer based on high-quality humic acid and fulvic acid can promote the formation of soil aggregate structure, reduce soil bulk density, increase cation exchange capacity, and regulate soil pH, thus contributing to improving soil water, fertilizer, heat preservation and ventilation capacity. Carbon based fertilizer processed by fertilizer ...

Principles for market-orientated production of compost products from the perspective of a plant operator
The treatment of biological waste, and composting in particular, has received a great boost in recent years since the introduction of source separation for biological waste in the 1980s. At the same time, legal regulations and guidelines for the construction of composting plants, production and trading of compost products were expanded. At present, about 6.5 million tonnes of biological waste is ...

What are the advantages of organic fertilizer production machine to make fertilizer from farm wastes?
Organic fertilizer production machine makes manure from farm wastes, mainly for livestock manure, kitchen and domestic garbage and other organic wastes to carry out aerobic high-temperature fermentation, kill harmful bacteria, add beneficial bacteria, use the activity of microorganisms to biodegrade and decompose them, so that the organic wastes can be transformed into usable organic raw ...

Difference between organic fertilizer and chemical fertilizer
What is chemical fertilizer Chemical fertilizers are quick acting and exist in many forms, such as liquid and particle. Chemical fertilizers are water-soluble, and plants can immediately absorb nutrients. Although this provides a fast nutrient and fast greening, it will not last. Only organic fertilizer can maintain plant growth all the time. Chemical fertilizer can promote plant growth rapidly, ...

NUE Explained: What is a Nutrient Use Efficiency score?
Are you making the most of your soil? Understanding your NUE score is pivotal to understanding not just nitrogen use efficiency, but also your soil’s overall potential. Effectively and efficiently managing inputs is one of the best ways growers can lower operating costs, maintain yield and reduce waste, but with so many factors impacting the production of each bushel, it can ...

Impact of fly–ash–amended soil on growth and yield of crop plants
Fly Ash (FA), a waste product of thermal power stations, has great potential for use in agriculture, because it contains almost all macro as well as micronutrients. In view of the potential disposal problem of FA, this investigation was carried out to search an economical and eco–friendly solution of its disposal by using it as nutrient source in agriculture for growth of crop plants. FA ...

RMDF Case Study - Compost Mulch a Plum Choice
ReMaDe Kent and Medway is managing a series of WRAP (the Waste & Resources Action Programme) funded trials on top fruit and other horticultural crops in Kent, the ‘Garden of England’, in order to develop the market for compost as a soil improver, and in this trial, as a mulch for young fruit trees. Twelve farms are taking part in the trials growing a wide range of crops, including ...

How the Earthworm Improves the Soil
Nature has ways of converting vegetable and mineral raw materials into high-quality products. The inconspicuous earthworm provides striking example — it is a minirefinery in the soil. The dew worm or common earthworm, which is native to Europe, is just one of more than 3000 earthworm species in the world. About 30 centimeters long, the powerful earthworm digs vertical burrows ...

Are endophyte-mediated effects on herbivores conditional on soil nutrients?
Neotyphodium endophytes are assumed to have mutualistic relationship with their grass hosts, mainly resulting from mycotoxin production increasing plant resistance to herbivores by the fungus that subsists on the plant. To study importance of often ignored environmental effects on these associations, we performed a greenhouse experiment to examine the significance of endophyte infection and ...
