What theory is capable in organic fertilizer?
Best insight from top research papers
Organic fertilizers are capable of mitigating problems associated with synthetic fertilizers and maintaining soil fertility. They gradually release nutrients into the soil solution, improve soil structure, and act as an energy source for soil microbes, resulting in healthy crop growth . Additionally, organic fertilizers can provide specific nutrients needed by plants during their growth period, improve plant yield and quality, and enhance disease resistance and cold resistance . They can also reduce soil heavy-metal pollution by adsorbing and passivating heavy metals, thus improving the quality and use value of the fertilizer . Furthermore, organic fertilizers can overcome soil hardening by improving soil bulk density, porosity, water retention capacity, and nutrient content, leading to increased plant emergence rate, survival rate, and yield . Overall, organic fertilizers offer a sustainable and environmentally-friendly alternative to chemical fertilizers, with various benefits for crop growth and soil health.

Organic waste as fertilizers?5 answersOrganic waste can be used as fertilizers to improve soil fertility and increase agricultural plant yield. Studies have shown that there is a large amount of unused organic waste in Azerbaijan that can be processed and used as organic fertilizers. Compost obtained from municipal solid waste dumps in Nigeria has been found to have good fertilizing potential and can be used as soil fertilizers. However, the concentration of nitrogen, phosphorus, and potassium in liquid organic fertilizers made from waste vegetable, charcoal, and snail in Indonesia did not meet the standard quality. In a greenhouse experiment in Malaysia, a combination of organic waste fertilizers with NPK fertilizer, particularly NPK 12:12:17:2 (10 g) + chicken manure (25 g), showed the highest growth and development of okra, reducing the dependency on inorganic fertilizers. The manufacture of liquid organic fertilizer from domestic waste using the 3R principle of Reuse, Reduce, Recycle has been successfully carried out, resulting in a cloudy white liquid with a tapai-like smell.
What are the different types of organic fertilizers?4 answersThere are several different types of organic fertilizers mentioned in the abstracts. One type is a combined type organic fertilizer, which includes components such as polyaspartic acid, fruit residues, calcium carbonate, potato straws, and entomogenous fungi. Another type is an agricultural green organic fertilizer, which includes manure of poultry and livestock, industrial and agricultural wastes, and wasted traditional Chinese medicine residue. A third type is a biological organic fertilizer, which is prepared from pig manure, plant straw, organic fertilizer starter culture, and various other components. Additionally, there is an environment-friendly type organic fertilizer, which is prepared from grain production wastes such as corn meal, wheat bran, and distiller's yeast. Lastly, there is an agricultural organic fertilizer that is prepared from potato straws, wheat straws, rice straws, cow dung, pig manure, and other ingredients.
What was the main idea of Liebig's theory on organic fertilizers?5 answersLiebig's theory on organic fertilizers focused on the importance of providing plants with essential nutrients in order to promote their growth and improve soil fertility. He emphasized the need for a balanced combination of nutrients, including nitrogen, phosphorus, and potassium, to ensure optimal plant development. Liebig believed that organic fertilizers, derived from natural sources such as animal manure and plant residues, were essential for replenishing the nutrient content of the soil and sustaining long-term agricultural productivity. He also recognized the role of microorganisms in the decomposition of organic matter and the release of nutrients for plant uptake. By advocating for the use of organic fertilizers, Liebig aimed to address the nutrient deficiencies in agricultural soils and promote sustainable farming practices.
What are the benefits of organic fertilizer?3 answersOrganic fertilizers have several benefits. They can improve soil structure, increase soil fertility, and enhance water holding capacity and nutrient holding capacity. Organic fertilizers also provide macro and micronutrients to the soil, which can promote plant growth and production. Additionally, the application of organic fertilizers can increase the stability of soil aggregates, as well as the organic carbon and total nitrogen content of the soil. Using organic fertilizers can also reduce the need for chemical inputs, promote sustainable agriculture, and have positive effects on the environment. Furthermore, the use of organic fertilizers based on livestock waste and agricultural waste can be a profitable strategy for farmers and breeders, while also utilizing abundant resources and being supported by government policies. Overall, organic fertilizers offer a natural and eco-friendly approach to improving soil fertility and crop yields.
What is the best theory about fertilizer?4 answersThe best theory about fertilizer is the one that relates yield to levels of applied fertilizer in terms of parameters that have direct physical meaning. This theory defines the contribution of the soil to the supply of nitrogen, phosphorus, and potassium for plant growth, as well as the responses to nitrogen, phosphorus, and potassium fertilizer at low nutrient levels. It also takes into account the level of nitrogen required to prevent growth by raising the osmotic pressure. Field experiments on French beans and summer cabbage have shown that this theory fits the yield data very well. Additionally, the theory suggests that small, time-limited discounts on the cost of acquiring fertilizer can yield higher welfare than heavy subsidies or laissez-faire policies, as they help farmers commit to fertilizer use without inducing overuse.
What is organic Fertilizer?5 answersOrganic fertilizer is a type of fertilizer that is derived from natural sources such as plant and animal waste. It is used in agriculture to provide essential nutrients to the soil and promote plant growth. Organic fertilizers can contain a variety of ingredients, including effluent, macroelements, microelements, microorganisms, and natural ingredients like molasses and aromatic ingredients. These ingredients help to improve the efficiency of the fertilizer, provide additional nutrients to the soil, increase microorganism activity, mask unwanted odors, and meet the nutrient ratio demands of crops. Organic fertilizers are rich in organic matter, have long-lasting fertilizer effects, and can improve soil quality, crop quality, and the ability of crops to resist drought, coldness, and disease. They also have the potential to produce potable water during the manufacturing process.
