But before we go on and take a look at the importance of organic matter in the soil, let us first of all find out what organic matter is. Remember that organic matter in the soil is a reservoir of nutrients and that decomposition of organic matter mineralizes those nutrients. Most of our productive agricultural soils have between 3 and 6% organic matter. Where organic matter levels are depleted (< 3.4% organic matter) it may be necessary, depending on soil type, to adopt farming practices that will restore organic matter levels in the soil. In this It relies on local natural conditions of the surroundings rather than using inputs (like fertilizers, pesticides, etc.) List of the Disadvantages of Organic Farming 1.

If the soil is deficient in these beneficial microbes then the plants cannot get the full benefits of the organics. The processes of organic farming store carbon within our soil. What does“organic” mean? And because these microorganisms need moisture and warmth to carry out this process, organic fertilizers get limited seasonally.

The choice of organic mulch mainly depends on the user but using an organic mulch means utilizing a material available in the field and it might be degraded and breaks down into organic matter.Organic mulch adds the nutrient in the soil and also increases soil fertility. DISADVANTAGES OF CULTIVATION Cultivation has the potential to destroy soil structure and make soils more prone to other forms of degradation, such as erosion. However, the good news is, the decaying matter in the organic manure itself will provide energy. Organic farming (often also referred to as organic gardening) can be defined as growing plants in an organic matter and without the use of chemical pesticides, herbicides, fungicides or other substances that could contaminate the soil and also our food. Apart from releasing nutrients, when organic fertilizers decompose, they improve soil structure increasing the soil’s ability to retain nutrients and water which eventually will make plants and soil strong and healthy. erosion,helpingtoavoidthe dustbowl effectseeninthe 1930s. Advantages and Disadvantages Organic Farming. the soil. Humus is organic material that has been converted by microorganisms to a resistant state of decomposition. It won’t drain well and may become anaerobic easily. Organic matter is a much used term referring to a wide range of invaluable materials for feeding plants, improving soil and as mulch. For organic manure to break down and nutrients are released into the soil, microorganisms are required. 2. Nutrient ratios are unknown and their overall percentage is less than that of chemical fertilizers. 5. Its composition ... disadvantages 25 7. If soil was ALL organic then when it gets wet it gets soggy ,sodden wet with little air spaces possible. Where there are no longer organisms to decompose soil organic matter and bind soil particles, the soil structure is damaged easily by rain, wind and sun. The term is also used to mean that the nutrients contained in the fertilizer are by-products of an organism or purely derived from an organism. The possibility of nitrogen depletion is another drawback of organic fertilizers. Soil organic matter is the fraction of the soil that consists of plant or animal tissue in various stages of breakdown (decomposition). 2. It does not unfortunately give guidance on an acceptable limit for inclusion of organic materials within structural fill, I have therefore always adhered to the view that all structural fill should be free from organic material. 3. Organic farming offers benefits to our climate to consider as well. What actually is organic matter and how does organic matter make the soil more fertile? The general consensus is the more soil organic matter the better. 9. They’re just soil amendments. Increasing organic matter in agricultural soil improves the soil structure, creating more air space and water retention within the soil.  HealthyEcosystem:OrganicFertilizerisgentleronmicroorganismsandearthwormslivinginthe This organic matter maintains the pH of soil; Organic matter reduces plasticity, cohesion, stickiness, etc. Organic matter is extremely important for the soil and helps the soil in numerous ways.

This is another big advantage of mulching. Because of the natural m a terial existing in organic fertilizer, soil structure is elevated and as an end result from the soil’s capacity to keep on water and vitamins increases. It also improves root penetration, allowing the root system of plants to expand and access nutrients and water. Organic matter plays an important role in maintaining soil quality. This helps seedlings burst through the surface and emerge to access sunlight. … The biggest disadvantage of using an organic fertilizer is that it may not contain primary nutrients like nitrogen, phosphorous or potassium, also known as NPK. Organic material is unstable in the soil, changing form and mass readily as it decomposes. Soil organic matter is a major source of N used by crops. The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. maintaining the quality of soil and ecological balance in the environment. The University of Missouri Extension suggests that organic matter make up at least 2 percent to 3 percent of the soil for growing lawns. Organic fertilizers release the nutrients in a slow manner as in some cases the cooler soil temperatures hinder the release of the elements. (GMOs),petroleum-basedfertilizers,andsewage sludge-basedfertilizers. 1. What actually is organic matter and how does organic matter make the soil more fertile?
