Dear Jadamers!
JADAM book, page 216, paragraph "17. Examples of Jadam fertilizer programs" :

A) Dr. Cho suggested to use 60 lt of GC-JLF, is this supposed to be the undiluted input to add to the 500 lt of diluted JMS solution?

B) Adding 1.5 kg of sea salt for a 3300 sqm surface, diluted in 1000 times means 1500 liters?

Won't the repeated sea salt treatment, 3-4 times before transplanting or flowering, over-salinize the ground?

Some land tends to hold salt and you wouldn't want to add any. Other land is deficient. Some areas of Asia receive a monsoon that washes the land clean every year.

I'm looking at land in the Philippines. Some places have coral based soil and most salt is lost during the rainy season each year. The addition of salt is considered the least expensive way to improve the yield of coconuts, bananas and other crops that are deficient. It used to be quite difficult to get salt to Inland locations on larger islands. Now you can hire a tanker truck bring thousands of gallons at once. It gets put in a big tank, then used as needed. Each location and soil is different.

Land that is able to take this regular addition of seawater, benefits from the other micronutrients that come with it. Plants take up the phosphorus, magnesium, iodine and other things, and they become part of the nutrient cycle. Salt that accumulates during dry times is likely to be lost during the rains. Seaweed can be added directly to the land without washing, for a much higher concentrations of those nutrients.
There were millions of the little blood suckers. But thanks to this tiny ad, I wasn't bitten once.
