Understanding Natural Fertilisers
Natural Fertiliser Definition and Types
Natural fertilizers sometimes referred to as organic fertilizers, are made from organic materials and include naturally occurring nutrients that are crucial for plant growth. These fertilizers are generally made of organic materials like compost, plant and animal waste, and other elements found in nature. Natural fertilizers offer a more balanced and gradual form of plant nutrition than chemical fertilizers, which are manufactured using industrial techniques and frequently include concentrated nutrients.
1. Natural Plant Fertilisers
- Compost: Decomposed organic material, such as kitchen leftovers, yard garbage, and leaves, results in compost. It improves soil structure, increases water retention, and enriches the soil with a variety of nutrients.
- Green Manure: Clover, lucerne, and other plant species are produced, then ploughed back into the soil while still green. Green manure serves as a cover crop and enriches the soil with nutrients like nitrogen as it decomposes.
2. Natural Fertilisers Based on Animals
- Manure: Animal manure, such as that from cows, chickens, or rabbits, is a rich source of potassium, phosphorus, and nitrogen. Additionally, it enhances soil texture and encourages the development of advantageous soil bacteria.
3. Natural Fertilisers Based on Minerals
- Phosphate of Rock: The phosphorus in this organic fertilizer is in a form that slowly releases into the soil, allowing plants to use it for an extended period of time.
- Bone Meal: Made from the crushed bones of animals, bone meal is a great source of calcium and phosphorus for plant growth.
Differences Between Them and Chemical Fertilisers
Natural and chemical fertilizers differ primarily in their content and mechanism of action. While chemical fertilizers offer an immediate nitrogen boost, natural fertilizers offer a more long-term and sustainable method of improving soil fertility.
- Release of Nutrients: Chemical fertilizers frequently have a rapid nutrient release, which causes an increase in plant growth. Nutrient leaching, in which surplus nutrients run away and contaminate water bodies, is another possible outcome of this. While minimizing the effects on the environment, natural fertilizers deliver nutrients gradually, giving a consistent and balanced supply to plants.
- Soil Health: Organic matter content, improved soil structure, and increased microbial activity are all ways that natural fertilizers improve soil health. When applied excessively, chemical fertilizers can have a deleterious impact on soil structure and reduce microbial diversity.
The Contribution of Organic Matter to Soil Fertility
In order to preserve ecosystem health and soil fertility, organic matter is essential. It performs a number of crucial tasks when compost or other organic fertilizers are applied to the soil:
- Supply of nutrients: Organic matter breaks down gradually, releasing nutrients like potassium, phosphorus, and nitrogen over time. This guarantees that plants receive regular nutrient supplies at all phases of growth.
- Soil Organisation: By strengthening the soil’s capacity to hold water and nutrients, organic matter strengthens soil structure. Additionally, it avoids soil compaction, which makes it simpler for roots to obtain nutrients and penetrate the soil.
- Microbial Activity: Organic matter provides soil microbes with food, encouraging healthy microbial activity. These microbes further decompose organic matter, releasing more nutrients and improving the general health of the soil.
- pH Control: Some organic fertilizers, such as compost, have the capacity to buffer soil pH, keeping it within the range that is most conducive to plant growth.
In conclusion, knowledge of natural fertilizers is crucial for environmentally friendly gardening techniques. While promoting soil health and reducing their negative effects on the environment, these organic alternatives offer an abundance of minerals. Gardening enthusiasts can grow successful gardens and help the environment by introducing natural fertilizers into their habits.
Typical Ingredients in Natural Homemade Fertilizers
Kitchen scraps (eggshells, coffee grounds, and vegetable peels)
Kitchen waste is a useful resource for making natural fertilizers at home. Vegetable peels are a great source of important minerals including potassium and phosphorus. Examples include peels from carrots, potatoes, and cucumbers. Eggshells give plants calcium, while coffee grounds are a fantastic supply of nitrogen for plants. These scraps can be gathered and placed in a compost bin or pile, where they will eventually break down and produce nutrient-rich compost that can be used as a natural fertilizer to feed plants and enhance soil fertility.
Yard Waste (Leaves and Grass Clippings)
Another rich source of organic matter for natural fertilizers created at home is yard waste, such as grass clippings and leaves. Grass clippings are a great “green” ingredient for composting because of their high nitrogen content. Conversely, leaves are a “brown” material in composting because of their high carbon content. They produce a balanced compost pile when coupled with kitchen scraps, promoting the decomposition of organic materials and producing a fertilizer that is high in nutrients.
Animal Manure (from Chicken, Rabbit, or Cow)
Due to its nutrient-rich content, animal manure has been utilized as a natural fertilizer for generations. Due to its high nitrogen content, cow manure is a great option for fostering lush vegetative growth. Phosphorus and potassium, which are essential for flowering and fruiting plants, are present in higher concentrations in chicken dung. Despite having a rather high nitrogen content, rabbit manure can be used as a moderate, all-purpose fertilizer. Composting animal manure is necessary before utilizing it to lower the danger of pathogen contamination and make the nutrients readily available for plant uptake.
The ultimate organic fertilizer, compost is created when a variety of organic materials, such as kitchen scraps, yard trash, and other plant residues, break down. It is a well-balanced source of micronutrients, potassium, phosphorus, nitrogen, and other elements. Compost improves soil structure, promotes advantageous microbes, and improves soil’s ability to retain water. Additionally, it aids in bringing the pH of the soil back to normal, which promotes the growth of plants.
Crops Grown on Green Manure (Alfalfa, clover, etc.)
Specific plant species that are produced and subsequently ploughed into the soil while still green, before they mature, are known as “green manure crops.” The ability of clover, lucerne, and other legumes to fix nitrogen from the atmosphere into the soil makes them ideal alternatives for green manure. Green manure crops enhance the soil by adding organic matter and raising nitrogen levels after being assimilated, which encourages strong plant growth.
By eliminating waste and recycling precious resources, incorporating these common items into homemade natural fertilizers encourages sustainable gardening practices while also providing plants with vital nutrients. Gardeners may grow healthier, more productive gardens while leaving a smaller environmental footprint by utilizing the power of nature’s bounty.
