Crop productivity and economics during the transition to alternative cropping systems
Many environmental benefits accrue from reducing tillage and increasing crop diversity; however, economic factors often encourage the continued use of intensive tillage and specialized crop production. This study examined crop yields, input costs, and economic returns during the transition to a range of cropping system alternatives in the northern Corn Belt region, including different system ...

Dairy cattle manure improves soil productivity in low residue rotation systems
Mineral fertilizer alone may not sustain soil productivity in cropping systems that return little crop residues to the soil, unless additional organic residues and/or manure is applied regularly to the soil. The objective of the present study was to assess the long-term effects of mineral fertilization (No fertilizer, PK, and NPK) and manure addition (0 and 20 Mg ha–1 yr–1) on soil physical and ...

Operation precautions of NPK fertilizer granulation coating
In the NPK fertilizer manufac?turing process, a coating process is added to make a slow-release fertilizer. Slow-release fertilizer is also called controlled-release fertilizer. The release rate of nutrients in fertilizers can be controlled to a certain extent for continuous absorption and utilization by crops. After the fertilizer is coated, it can reduce the loss of fertilizer nutrients, ...

Method for fermenting organic fertilizer by peanut shell
Peanut shell is a rare plant waste and flower fertilizer. As a kind of soil loose agent, it is often used in soil cultivation. If the peanut shell is not rotten, it is not conducive to the growth of plants. If the peanut shell is used in plants, it will have some side effects on the root growth of plants, and may also affect the absorption of nutrients and burn the root system of plants. ...

The mineralization of nitrogen from compost in the tropics
The application of organic matter is very important in maintaining high and stable crop yields under tropical conditions. Most of tropical soils are characterised by low content of organic matter and low structure stability. Animal wastes contain many nutrients, including nitrogen, phosphorous, potassium and other minerals. In addition to supplying nutrients, the application of animal wastes also ...

Potential of crop residue in India as a source of energy
Here is given an estimate of crop residue production and different recycling options as a source of renewable energy. India produces 388 Tg crop residues but only 182 Tg equivalent to 2818 PJ is usable. Recycling as manure can replace 15% of 595 PJ national fertiliser energy. Recycling in digester can produce 20.32 billion m? biogas. It can be converted into 182 Tg of biocoal generating 156?258.3 ...

Vermicompost production and its use for crop production in the Philippines
Vermicompost was produced with Perionyx excavatus and Eudrilus eugeniae using animal manures, leguminous leaves, grass and agro-forestry wastes. Yields of corn fertilised with vermicompost at 5t/ha and rice at 2t/ha of vermicompost were comparable with those for corn fertilised with 100% chemical fertilisers and 40% increase over the control for rice. Chinese cabbage and eggplant fertilised with ...

How to Compost Pig Manure into Organic Fertiliser
In general, a 200lb pig would produce about 13lb manure per day. Pig manure contains plentiful essential nutrition ingredients like nitrogen, phosphorus and potassium for plant growth, which can promote healthy growth and increase the yield of grain crop. Even though pig manure is a commendable raw material of organic fertilizer, lots of pig manures carry E.coli, salmonella, parasitic worms and a ...

Why organic fertilizer equipment is suitable for small investment
In agricultural production, in order to achieve the increase of crop production, people do not hesitate to pour a large number of chemical fertilizer into the farmland. More and more nitrogen, urea and nitrogen, phosphorus, potassium compound fertilizer are used, and the concentration is higher and higher. Although this has kept the effect of increasing production to a certain extent, the ...

A Guide to Compost Sheep Manure for Organic Fertilizer
Sheep manure contains protein, organic acid, cellulose, aliphatics and so on, and its organic matter content is higher other livestock manure. Without fermentation, sheep manure has various harmful bacteria that cannot be directly used on plants growing, or there would bring germs and parasite spreading. What’s worse, without proper disposal, sheep manure would generate heat to consume oxygen in ...

Pond fertilization / Aquaculture
Just as fish need good water quality conditions to thrive, they also need an abundant supply of food to grow. We can provide food for our fish in two different ways: We can give them “artificial” feeds that are prepared either commercially or at home, or we can ensure that they have an abundance of natural foods by using fertilizers to increase pond productivity. In either case, it is ...

Application of Biochar in Poultry Farming
In the ever-evolving landscape of sustainable agricultural practices, biochar emerges as a promising contender, offering a multitude of benefits to poultry farming operations worldwide. Derived from the biomass pyrolysis process, biochar is a carbon-rich substance renowned for its capacity to enhance soil health, improve nutrient retention, and mitigate environmental degradation. Its application ...

What is the development trend of organic fertilizer production process?
Organic fertilizer production process uses straw, livestock and poultry organic matter as raw materials, and harmless treatment of pollutants through equipment to produce organic fertilizer. This production project mainly uses chicken, duck, goose, pig excrement and crop straw as the main raw materials, uses the natural fermentation of microbial flora and organic matter, adds nitrogen release ...

Valorising Agri-Waste – Agriculture produces an unsustainable amount of waste, so how does the bioeconomy let us derive value from it?
For every kilogram of “usable” crop produced in agriculture, between 1 and 2.5 kilograms of residue is also produced. Of course, some of this residue must remain in the field or be used elsewhere on the farm in order to maintain a healthy ecosystem, but that which isn’t used thus is an unavoidable waste. Minimising waste is one of the central tenets of sustainability: the waste ...

Manure drying tunnel doing a good job - Case Study
Generating power from renewable energies is becoming increasingly important in Germany as well as on the international level. Thus, it is not surprising that the number of biogas plants is steadily increasing as are wind power plants and solar plants. On the agricultural sector, biogas plants are an additional source of income on many farms besides crop production and livestock husbandry. When ...

Decomposition of carbon-14-labeled organic amendments and humic acids in a long-term field experiment
The stabilization of soil organic matter (SOM) is an important process in the context of global change and is strongly affected by soil use and management. We investigated the mineralization and stabilization of 14C-labeled wheat (Triticum aestivum L.) straw and 14C-labeled farmyard manure under different cropping systems (crop rotation, monoculture, and bare fallow) in a long-term field ...
