Few differences between chemical fertilizers and manure with examples
The longer you use organic fertilizers, the easier it will be to maintain the level of organic fertilizers for the succeeding application. Rich in NPK BUT long term application can cause soil dehydration and destruction of plant tissue. Excessive nutrients can bind up other nutrients in the soil, making them unavailable to the plants. The longer chemical fertilizers are applied, the higher the quantity you will require for the succeeding application. Minerals Content: Microbes convert the organic matter to various nutrients and minerals. Minerals are typically present in broad range that complements with the soil, providing more balanced nutrition to plants. Lacks organic matter and lessens the activity of microbes in the soil. Corrects Imbalances: As the soil goes through the plant cycle of planting, harvesting and de-cropping, it becomes stripped bare of nutrients and the pH balance is also affected. Organic fertilizer helps correct imbalances in the soil pH to make it suitable for plant growth. It does not disturb the balance of the soil as it does not leave behind artificial compound. Turns soil into acidic. Direct application of high dosage can burn the roots of the plants due to high salt concentration. Environmental Footprints: Doesn’t build up harmful residues or cause pollution due to run-off from irrigation or rain.
A by-product of an organic process and require minimal further processing and energy/resource consumption to make usable. Chemical fertilizers tend to release many chemicals into the soil that contain nutrients helpful to soil BUT it may also contain elements that are not easily biodegradable. These may go on to contaminate our land and bodies of water.High energy consumption is also required for production. Water Holding Capacity and Aeration: Organic fertilizer blinds sandy soil and loosens clay/muddy soil. This provides the soil both the capacity to sustain water and good aeration for movement of microbes and healthier plant growth. Caused the soil to dry up that result in caking or hardening, which is difficult or impossible for planting.
Fertilizers are made up of macronutrients such as nitrogen, phosphorus and potassium. These are called primary macro nutrients. They also contain secondary macro nutrients such as calcium, magnesium and sulfur. Other substances in smaller quantities are also present in fertilizers such as iron, copper, boron, chlorine, manganese, zinc, and selenium. Fertilizers are added externally to the soil either by adding to the soil itself or by spraying on to the leaves of the plants that gets carried into the soil. There are various types of fertilizers available in the market containing these macro nutrients in varying proportions and one can choose a fertilizer depending upon the health of his soil.
Fertilizers can be either natural (organic) or synthetic. Natural fertilizers are those that are derived from plants or animals while synthetic fertilizers are those made in a laboratory. While natural fertilizers never harm the quality of soil and do not damage the produce, overuse of synthetic fertilizers may harm the soil in the long run.
Manure is nothing but organic matter that is used as a fertilizer to increase the level of nutrients in a soil. Cow dung is natural manure that contains macro nutrients and help plants to grow rapidly. These organic products are rich in nitrogen and other vital macro nutrients and can be used whenever one feels that the quality of soil is going down. Now manures can be either derived from animals or obtained from plants. There are also compost manures. Feces of animals such as cows, pigs, sheep, goat, rabbit and birds contain elements that are considered beneficial for the health of soil. Some plants have these nutrients in their parts such as leaves (e.g. Clover). Compost is manure that is hybrid in nature as it contains both animal and plant remains.
~~• Fertilizers are products that are beneficial for the quality of soil
• Adding fertilizers in required quantity helps in increasing the yield. Manures are organic fertilizers
• Fertilizers can be inorganic also (synthetic fertilizers)
• Manures can be added to soil without any fear while inorganic fertilizers must be added after careful examination of the soil quality to decide which are the nutrients soil is lacking from.
