OBJECTIVE FORESTRY

Detailed explanation-1: -The 17 Essential Plant Elements include nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel. The non-mineral essential plant elements include hydrogen, oxygen, and carbon. These are either taken up as a gas or water.

Detailed explanation-2: -Summary. Plants require 18 essential nutrients to grow and survive, classified by their importance into macronutrients (C, H, O, N, P, K, Ca, Mg, S) and micronutrients (B, Cu, Fe, Mn, Zn, Mo, Cl, Co, Ni). Study Tip!

Detailed explanation-3: -Like humans, plants require certain key nutrients to grow well, develop, reproduce and remain healthy. The performance of a crop in the field depends on the genetic makeup of the variety grown, fertility and pesticides programs, and interaction with the environment.

Detailed explanation-4: -There are 15 essential elements that plants must have in order to grow properly.

Detailed explanation-5: -the macronutrients: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulfur (S), magnesium (Mg) the micronutrients (or trace minerals): iron (Fe), boron (B), chlorine (Cl), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni)
