The antagonism and synergism function analysis of the trace elements in the soil.

The antagonism and synergism function analysis of the trace elements in the soil. WHY the test results show no shortage of trace elements in the soil, but the crop is to show the lack of trace elements? Many farmers or land owers meet the same problem, we tested our soil many times and all the data tells us that everything is perfect. But every time we sowing seeds into it, and the result was not satisfactory. So, what is wrong? The answer is antagonism&synergism function of the elements. Let’s put more details as following picture: Antagonism: P:  K, Cu, Zn, Mo, Si; NH4+: Ca, Mg, Mo; No3+: B; K: Ca, Mg, B;

Oil palm tree nutrient management, fertilization of oil palm tree

Oil palm tree nutrient management Oil palm tree nutrient management   Oil palm trees: tropical crops, like high temperature, no wind and low temperature, etc., for the production of fruit trees, generally three to four years began to fruiting. Its nutrition management is divided into two stages: growing  trees and mature  trees. To growing tree: saplings   mainly with high nitrogen-based with phosphorus and potassium fertilizer, the proposed 30-10-10 type of recipe, with 2-3 kg per acre of mono potassium  phosphate. Can be once every quarter, each time per acre (12-15 trees) 10-20KG. Two adult trees: adult tree hi high temperature and humidity, non-resistant non-drought resistance to low temperature (critical point of 15 degrees), prefer potassium, before the flowering recommended 1-2 times high nitrogen fertilizer 30-10-10 ( 1:500 ratio foliar spray) to promote flower bud differentiation, fruit to high potassium fertilizer, especially like potassiu...
