Fertilizer plants at the time), the plants need. Plants grown in soil enriched with nutrients not usually dwarf the low, and productivity kraen. The fertilizer will help enhance nutrient shortage, there is sufficient quantity of plants. However, The fertilizer in the soil of the same type, the same plant may have different results. Depending on the timing (timing) of the fertilizer plant, it corresponds to the length of time a plant nutrient that is required at most? The range of nutrient needs strokes most of the plants of each type will vary. Plants that have a short lifetime, such as crops and rice will have a rhythm to get uptake markedly different at least 3 range.(1) the range of the first plant began to sprout and grow within 30-45 days for the first. Plants usually require less nutrients and slow. Because the root system and also the beginning of the. (2) a rapid growth phase where plants need nutrients are many. For rice, it is different, and that is that the extremists are creating a tad out. If the corn is at the age of 45-60 days, if it is 30 days before rice went about flowering and. (3) the range of full growth, and create a seed or create effects. Nutrient requirements at this stage will be reduced until the seed pods or an unforgettable. The plants need nutrients from the soil and nutrients from the soil to engage in fast rate is the range of the second phase, it is growing rapidly and needs cleaning, the sasomthatu and the grain, enough to generate results that will occur during the third, so the fertilizer plant, it is important that this second stage, in which plants should get nutrients from fertilizer, enough to last. Therefore, fertilizer plant to split insert The insert should fit within the plants to the effectiveness of the fertilizer supplied to the high suitability of the timing, plant fertilizers has been studied extensively. Each of the plants should be divided so that a fertilizer is the most productive plant vary, but may be considered a large basis. 3.1 breakdown of fertilizer is often detrimental to the same amount of fertilizer only once, now grown, except when using a very low rate of fertilizer. 3.2 entering for the first time, is now grown in less insert wear, but especially nitrogen fertilizer, fertilizer, phosphate fertilizer, and a section that will put all thaet now grown. 3.3 entering the second phase should be put on fast-growing plants, such as between the different stages up to extremists near trees, mainly to put a second time would be a nitrogen fertilizer. If the rate of nitrogen fertilizer that is used very high breakdown should be inserted three times, is now beginning to grow rapidly and short flowering and will soon go over the stage after flowering plants, or plants that start an unforgettable. (4) where the plants, fertilizer plants, can be tempting to take advantage of the fastest.In addition to the entry method to enter the rhythm, so that the plants are attracted to use it effectively is important. This is because in the fertilizer into the soil is in reaction to the changes and the movement of fertilizer will take place immediately.Nitrogen in the fertilizer will move very quickly because of the easily soluble. Nitrogen in Chennai water concentrate will be blowing out the layers of Earth, convection quickly. If the root is not attracted to plants, they will lose him and not be beneficial to plants. Usually, nitrogen fertilizer in the soil will be lost. By wash, about half the number that entered into it. Nitrogen in the form of aemmoniam, even though it sucked outside surface of clay particles and are difficult to wash, it's true. When the soil has good ventilation will be processed by microorganisms in the soil to make the reaction. Oxygen (oxidized) to Chennai (NO3-N) concentrate easily and very quickly. ฟอสฟอรัสในปุ๋ย ถึงแม้จะละลายน้ำได้ง่าย แต่เมื่ออยู่ในดิน จะทำปฏิกิริยาอย่างรวดเร็วกับแร่ธาตุต่างๆ ในดิน กลายเป็นสารประกอบที่ละลายน้ำยาก ความเป็นประโยชน์ต่อพืชลดลง และไม่เคลื่อนย้ายไปไหน ดังนั้นเมื่อใส่ปุ๋ยฟอสเฟตตรงจุดไหน ฟอสเฟตที่ละลายน้ำได้ง่าย ก็มักจะอยู่ตรงจุดนั้น ถ้าจะเคลื่อนย้ายจากจุดเดิม ก็เป็นระยะใกล้ๆ ในรัศมี ๑-๕ ซม. เท่านั้น ดังนั้นการใส่ปุ๋ยฟอสเฟตให้กับพืช จึงต้องให้อยู่ใกล้กับรากมากที่สุด เพื่อที่รากจะไม่เป็นอันตรายจากปุ๋ยนั้น การใส่บนผิวดิน จะเป็นประโยชน์ต่อพืชน้อยกว่าใส่ใต้ผิวดินในบริเวณที่รากจะแพร่กระจายไปได้ถึง ซึ่งผิดกับปุ๋ยไนโตรเจน ที่ใส่บนผิวดินก็สามารถซึมลงมายังบริเวณรากที่อยู่ใต้ผิวดินได้ง่าย ดังนั้น การใส่ปุ๋ยไนโตรเจนใต้ผิวดินจึงไม่มีข้อดีไปกว่า ใส่บนผิวดินPotassium fertilizer to move easier but more slowly than nitrogen, phosphate, potassium in the fertilizer, soluble nitrogen as it's actually easier, but because there is a prachubuak that suck based on the surface of clay particles is so difficult but it was washing a plant is so easy to put on, so put the potassium fertilizer on the soil surface or below ground surface, but the movement will be slower than the nitrogen and at the same time losing by wash.
