It relies on local natural conditions of the surroundings rather than using inputs (like fertilizers, pesticides, etc.) The use of organic fertilizers helps to retain nutrients from the soil. In fact, the plants may show signs of nutrients deficiency in the first months of the application as breakdown hasn’t picked up yet. What actually is organic matter and how does organic matter make the soil more fertile? First we must define “organic” to make a proper comparison. The term “organic” referstothe way agricultural productsare grownand processed.Specific The difference between soil texture and soil structure (effects of excessive tillage), the advantages and disadvantages of each soil texture (clay, silt, sand), the importance of organic matter in the soil. If soil was ALL organic then when it gets wet it gets soggy ,sodden wet with little air spaces possible. 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. Increasing organic matter in agricultural soil improves the soil structure, creating more air space and water retention within the soil. Organic farming also conserve water and soil. Looks like you’ve clipped this slide to already. contributesto soil healthinthe followingways: The fine particles, clay and valuable organic matter are eroded first, leaving a poor, hungry soil. Creatingyourownorganic fertilizerfromleaves,grassclippings,kitchenscrapsandyarddebrisrecycles Different farming techniques cause negative effects on organic matter in the soil. Though it is expensive , it saves much of our money in other ways. Clipping is a handy way to collect important slides you want to go back to later. Nutrients are so low that a huge quantity of manure has to be added for the desired dose of nutrients. Sewage sludge, fish emulsion, blood meal. This can lead to rainwater runoff and soil erosion (Plate 3), removing the potential food for organisms, i.e. Organic Matter is so helpful to us. What are the disadvantages of using organic fertilizers? Organic mulches are more beneficial than inorganic mulches. Used well, mulch is highly beneficial for any garden but it does come with a set of disadvantages you should consider. And because these microorganisms need moisture and warmth to carry out this process, organic fertilizers get limited seasonally. Organic matter is a much used term referring to a wide range of invaluable materials for feeding plants, improving soil and as mulch. 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. Whether we are farmers or not, we all know that the success of any plant relies on how it is cared for. 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. in soil. Misuse of fertilizer and livestock manure is a problem, but excess organic matter can be a problem too. (GMOs),petroleum-basedfertilizers,andsewage sludge-basedfertilizers. It enhances the fertility of the soil but there are other types too. Most of our productive agricultural soils have between 3 and 6% organic matter. 5.
