In farming, whether on a large scale or small scale, the ultimate goal remains to enhance crop production and increase profits. To achieve this, fertilisers are commonly used to supply essential nutrients such as nitrogen, phosphorus, and potassium to the soil. However, an improper or excessive application of fertilisers can lead to significant loss of minerals from the soil, which in turn causes crop loss and diminishes soil fertility. In developing countries, where farmers often rely on external inputs for boosting yields, there may be a lack of awareness about the effects of overuse, making it a costly and unsustainable practice. This is where manure comes into play, offering a more natural, organic solution.
The Key Difference Between Manure and Fertilizers Explained
Unlike fertilisers, manure is an external source of nutrients that can gradually replenish the loss caused by repeated farming. It helps improve soil structure, particularly for infertile lands, by returning organic matter to the earth, which enhances its ability to retain water and nutrients. Though it may not immediately yield the same results as chemical fertilisers, manure contributes to soil health in the long term. The challenge, however, lies in the capital required for manure management, which can make it less accessible in developing countries or to farmers without sufficient resources. Proper seed selection and management practices are also key to ensuring that the benefits of manure are fully realized without risking loss of fertility.
Manuring
Manuring is the process of adding organic or natural materials like dead wastes from plants, humans, and animals, along with excreta, to the soil. These organic products undergo decomposition, releasing essential nutrients that enhance the soil‘s fertility. Unlike chemical sources, manure improves not just the nutrient profile of the soil, but also its water holding capacity, aeration, and texture, making it more suitable for crop growth. When applied properly, organic manure promotes long-term development of the soil, fostering better root growth and enhancing the overall structure. It is an integral part of organic farming, where organic fertilisers are preferred over synthetic ones, reducing the need for harmful pesticides. Through this method, the soil becomes richer and more capable of sustaining healthy crops, without relying heavily on external chemicals. What stands out with manuring is its ability to create a sustainable farming system where nature’s own recycling process takes care of the soil‘s needs, unlike quick-fix chemical solutions.
Which Types of Manure Exist?
When we look at manure as an alternative to synthetic fertilizers, it’s clear that this organic material offers a range of benefits, not only supplying nutrients but also enhancing the soil structure over time. The waste produced by omnivores and herbivores such as chickens, pigs, cows, alpacas, and horses can be transformed into manure that, when properly composted, becomes a rich source of macronutrients and microelements. Unlike chemical fertilizers, which can leach minerals from the soil with high quantities of nitrogen and other elements, manure is a more balanced solution. The organic matter in manure helps improve the soil’s ability to retain water, aerate the ground, and maintain an optimal structure for crops to grow.
The content of manure depends largely on the type of animal that produced it. For instance, cows and pigs often provide aged manure, rich in essential nutrients for plants, while chickens produce high-nitrogen manure that needs to be composted for some time before it can be safely applied. The decomposition process gradually releases minerals that are required for the sustained growth of crops and other vegetation, offering a slower release of nutrients compared to fertilizers. This sustainable practice ensures that the soil continues to be rich in essential elements, fostering long-term crop health and maintaining soil fertility, without risking the adverse effects of over-application, often associated with chemical alternatives.

FAQS
What is manure and fertilizer?
Manure is a natural substance, primarily consisting of fecal waste from livestock animals, that has been decomposed and processed to be used as a nutrient-rich addition to soil. It is often applied for agricultural use to promote the growth of plants by replenishing essential nutrients. Manure can be collected from various animals and, when properly managed, is an excellent way to improve soil health and fertility. On the other hand, fertilizer refers to both natural and synthetic compounds designed to provide specific nutrients to plants quickly. While fertilizers are often commercially used and can be tailored to meet plant growth needs, they lack the broader range of organic matter found in manure and may need to be applied more frequently to maintain soil health. Both manure and fertilizer serve to promote healthy plant growth, but their application and effects on the soil differ due to their composition and nutrient delivery method.
What is called manure?
Manure is a blend of organic materials from animal waste, including feces and urine, along with plant matter like straw and bedding. This combination undergoes decomposition, resulting in a nutrient-rich substance that can be absorbed by the soil to improve its fertility. It serves as an excellent natural source of nutrients for plants and is commonly used in farming to enhance soil health and promote plant growth. Manure is a versatile organic material that not only nourishes the soil but also helps retain moisture and improves soil structure. By utilizing manure, farmers take advantage of natural waste materials, reducing the need for synthetic additives while enriching the land with vital nutrients.
What are the three types of manure?
In agriculture, manure is typically classified into three main types: green manure, farmyard manure, and composted manure. Green manure consists of plants grown specifically to be incorporated into the soil, boosting its nutrient levels and organic matter. Farmyard manure is a combination of livestock manure, bedding, and plant material, often sourced from farm animals, and it provides a rich mix of nutrients like nitrogen, phosphorus, and potassium. Finally, compost manure is created through the controlled decomposition of organic waste such as kitchen scraps, leaves, and other plant materials, making it a valuable, nutrient-dense addition to the soil. All three types offer different benefits, but they share the ability to improve soil health, support plant growth, and enhance soil fertility in a more natural, sustainable way compared to synthetic fertilizers.
What is the best type of manure?
The best manure for gardens often depends on the specific needs of the plants, but chicken manure stands out as a rich source due to its high content of nitrogen. It provides an excellent nutrient boost for plants when properly composted or aged, reducing the risk of burning plants. To maximize its effectiveness, chicken manure should be applied in the fall or spring, giving it a chance to compost and break down before the growing season begins. This process allows it to release its nutrients gradually, improving soil health and providing a steady supply of nutrients to the plants throughout the growing cycle. Whether it’s composted or aged, the key is ensuring it is handled properly to avoid nutrient overload, making it an ideal choice for boosting plant growth without harming the soil.
Which one is better, fertilizer or manure?
When comparing manures and fertilizers, deciding which is better largely depends on the goals of the farmer and the specific needs of the soil. Manures excel at maintaining soil fertility over the long term because they add organic matter that helps improve soil structure, water retention, and the overall health of the soil ecosystem. They are also free of the chemicals that can sometimes be found in fertilizers, making them a more natural choice for those focused on sustainability. However, fertilizers are more effective for quickly adding nutrients and boosting plant growth, especially when there’s an urgent need for specific nutrients. Yet, fertilizers can affect soil health over time by depleting organic matter and may contribute to a gradual decrease in soil fertility if used constantly. The presence of chemicals in synthetic fertilizers also has the potential to harm the soil’s natural microorganisms, reducing its long-term productivity. Ultimately, the choice depends on the potential risks and benefits of each approach and how they align with sustainable farming practices.
