Organic nutrients can be provided to plants through naturally occurring fertilizers like peat, kelp, slurry, manure and, worm castings. Nitrogen, Potash, and Phosphorous along with other essential micronutrients when provided to plants through organic sources will result in healthy growth of plants. They also increase fertility level of soil and are completely biodegradable. Organic nutrients even if provided in excess to your plants, have no harmful effects unlike in case of chemical fertilizers.
Hydroponics plant thrive on organic nutrition as well. Many hydroponic growers have reported that the growth rate of plants has increased with the use of organic nutrients. Organic fertilizer like Bat Guano is rich in nitrogen and helps in healthy growth of hydroponic plants. Another such fertilizer, earthworm casting are used traditionally to provide organic nutrients. Fishmeal along with providing nutrients to plants, also introduces growth enzymes in hydroponic nutrient media. Organic nutrients help the growth media to be rich in beneficial microbial growth.
Organic nutrients have many advantages. They help in improving soil structure by retaining moisture and humus to the soil. Nutrients are released at a slow yet consistent rate in to the soil. This helps in avoiding bloom-and-bust pattern in plants. Topsoil erosion is prevented with the help of organic nutrients. Inorganic nutrients are washed away with rain or irrigation water and the harmful chemicals accumulate in nearby water bodies. This causes harmful effects to the life in the water body. Organic nutrients on the other hand, even if get washed away to a pond or lake, they cause no ill-effect to the flora and fauna of the water body.
Organic fertilizers act as storehouse for many micronutrients, gibberins, auxins and many other useful elements. It is found that root expansion is better in plants which are provided with organic nutrients than the plants which are provided with chemical fertilizers. With the use of organic nutrients you can grow healthy, blooming plants, crops with better yields, and tasty, delicious fruits and vegetables and all this without any side-effects!
