Soil Testing Articles-by Allan Fulton
Plant Micronutrients: boron, chloride, copper, iron, manganese, molybdenum, nickel, and zinc.
This article discusses micronutrients and the use of soil tests to evaluate their levels in orchard soils. Micronutrients are essential to almonds and other nut crops, yet are required in much smaller amounts than macronutrients such as nitrogen, phosphorus, and potassium or secondary nutrients such as calcium, magneium or sulfur. The eight micronutrients are boron (B), chloride (CI), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), and zinc (Zn). This article will help you understand the important roles these micronutrients play in the plant and in orchard management.
