After my 2 month coma stone we are back at it. New digs too.
*burp* It's all bout the salt
Plants need 17 elements for normal growth. Three of them--carbon, hydrogen, and oxygen--are found in air and water. The rest are found in the soil.
Six soil elements are called macronutrients because they are used in relatively large amounts by plants. They are nitrogen, potassium, magnesium, calcium, phosphorus, and sulfur.
Eight other soil elements are used in much smaller amounts and are called micronutrients or trace elements. They are iron, zinc, molybdenum, manganese, boron, copper, cobalt, and chlorine. They make up less than 1% of the total but are nonetheless vital.
Most of the nutrients a plant needs are dissolved in water and then absorbed by its roots. In fact, 98 percent are absorbed from the soil-water solution, and only about 2 percent are actually extracted from soil particles.
