Tea is the most important part of the above leaves, tea leaves, but a there is a problem, then it means that the quality of tea, tea production is greatly reduced, so serious that it loses its value, which is a symptom of the color of tea shallow yellow, which is caused due to deficiency symptoms, that this is what is missing elements, should the use of water-soluble fertilizer that a large number of elements to complement it? Shallow tea leaves turn yellow, it is caused due to the lack of nitrogen, due to the growth of tea more high temperatures and humidity in the southern region and large, this environment will promote the soil nitrogen fertilizer consumption, coupled with volatile etc. This results in less nitrogen in the soil can be quantitative, or lack of nitrogen fertilizer, etc., can not meet the growth of tea, which led to the result of nitrogen deficiency and unable to meet its growing demand, resulting in lighter yellow leaves, in which Under the case would add to their available nitrogen, applying nitrogen-based water-soluble fertilizer macronutrients, because it contains a lot of nitrogen, and contain other nutrients needed for growth of tea in the supplemental nitrogen, while also able to prevent other elements missing, while chelated trace elements too, can make it faster and better absorption. So shallow tea leaves turn yellow due to nitrogen deficiency is the choice of type of macronutrient soluble nitrogen fertilizer, which can quickly add nitrogen for tea, and safe pollution-free, so they can quickly return to normal state, glossy leaves of fresh and improve their quality.
