Liquid fertilizers may be applied in the following ways: It is the most suitable method under dryland agriculture and in areas prone to erosion problems. The use of liquid fertilizers is not a very common practice, but this is the most common method in advanced countries. Small mud bolls are prepared, and these boll or pellets are dropped near the crop rows in rice Jr jute under deep water conditions. The fertilizer is well-mixed with soil after slight moistening, filled in gunny bags, and stored for two to three days. In this method, fertilizers (especially nitrogenous ones) are mixed with clay soil in the ratio of one part of fertilizer into 10-15 parts of soil. It is not easy to apply fertilizers in typical methods as the fertilizer granules get dissolved in water before reaching ground level. This method is adopted, especially in deepwater rice cultivation. Care must be taken so that seeds are not burnt by contact with fertilizers.Suitable for wide-spaced crops like cotton, castor, cassava, cucurbits, and chili.Fertilizers are placed deeper into the pocket (dibble), and seeds are sown in the same pocket about 5 cm above the fertilizers. When fertilizers are placed at a fixed spot with the help of a bamboo peg having a hole at the bottom in the case of very widely spaced crops, then the method is termed as pocket/spot placement method. When the soil surface is dry, this method gives very promising results.įertilizer is applied in a circle around an individual plant or hill base at a depth of about 2.5-5 cm. This method has a definite relationship of fertilizers with seedlings or seeds as the fertilizer is placed to the side of seedlings or seeds some distance away from them or at the seed level, above or below or by the side of the seed level. This method is also termed a discontinuous band application.Īlong the entire rows of closely spaced crops like cereals, minor millets, potatoes, and tobacco, fertilizers are applied continuously at 2-2.5 cm depth. In the hill, for widely spaced plants like cotton, castor, and cucurbits, fertilizers are placed on either side of plants along or across the row but not along the entire row. It may be of two types as the bands may be continuous or discontinuous: It is a localized placement of fertilizers by the side of plants or seeds (about 5 cm apart). Well-decomposed manure, ashes, and P and K fertilizers in small quantities are used along with seeds during sowing.Ĭare must be taken so that seeds are not burnt by contact with fertilizers. Sometimes fertilizer is drilled by implement, and seed is sown in the same furrow. It is done by using seed-cum-fertilizer drill. When placing fertilizer along with the seed, then it is called contact placement. The method could be adopted in the following ways: The method is very technical and needs special precautions.It increases fertilizer recovery and the response of crops to applied doses.Fertilizers come in easy reach of crop roots.Placing fertilizers in the moist zone, where they remain available to plants for a more extended period.Relatively lesser quantity is required for the production of an ideal crop Localized placement of fertilizers has many advantages over broadcasting methods of application such as. At the same time, the latter implies the application of fertilizer into the soil close to the seed or plant. The former refers to applying fertilizer into the soil without special reference to the location of the seed or plant. There is a distinction between placement and localized placement. P and K fertilizers are placed in deeper layers by heavy machinery to avoid fixation in strongly acidic soils. The method is termed sub-soil placement when placing fertilizers deeper than the seeding or planting depth and deeper than the previous two methods.
