To summarize crucial parts of video for those of you that don't speak spanish:
This is a project in Mexico to produce mangos either early or late to get maximum price for their product. Kent, Ataulfo, and Tommy Atkins are produced early. The Keit is produced later than mormal. Three applications of foliar applications of potassium nitrate starting mid November are used, 15 days apart. First application is 3%, second 2%, and third is 1%. The variety used is all Kent, which is the main cultivar produced. Applications are done first thing in the morning and watering is witheld during times of potassium nitrate spraying.
They also discuss another flower initiator, Butrasol, for use on Tommy Atkins and Ataulfo. Measure area of drip line width by length, multipy by 2 and then use 2 ml per square meter of tree area. For an 8-10 year old tree that usually turns out to be between 25-35 ml per tree of spray. That amount is dissolved in between 1 and 2 liters of water depending on drainage of the type of soil. If your soil is sandy use 2 liters, for clay soils use 1 liter. Then spray around base of tree at a distance of 50 cm from trunk and at depth of 2-5 cm. It's important to spray correct amounts as Butrasol is a product that produces a lot of stress and if too much is applied the tree will dry out (die).
