Что такое макро- и микроэлементы?
Все элементы питания, которые необходимы для нормального роста и развития растений, можно разделить на две группы.

К первой группе относятся макроэлементы, используемые растениями в значительных количествах, — это углерод, кислород, водород, азот, фосфор, калий, кальций, магний, сера, железо.

Ко второй причисляют микроэлементы, потребность в которых очень мала, — бор, марганец, медь, цинк, молибден, кобальт и т.д. Все необходимые элементы содержатся в органических и минеральных удобрениях.
