    2. 1.2A chemical element (e.g., potassium, magnesium, calcium) required in large amounts for plant growth and development.
      • ‘Soil samples were also evaluated for pH and other macronutrients by the Arkansas Soil Test Laboratory to ensure that any nutrient deficiencies could be appropriately amended.’
      • ‘It is one of the three macronutrients (in addition to nitrogen and phosphorus) required by plants.’
      • ‘We always think of plants as requiring the usual N-P-K macronutrients (nitrogen, phosphorus, and potassium), but we sometimes neglect to provide the many micronutrients roses and other plants need.’
      • ‘It is chemically similar to sulphur, an essential plant macronutrient.’
      • ‘Despite phosphorus being an important macronutrient required for plant growth and function, many soils throughout the world are deficient in forms of P that are readily available to plants.’
      • ‘This factor may reflect essential plant macronutrients from materials leached from tree foliage and bark, or deposition of pollutants brought into the area by long-range transport.’
      • ‘Sulfur is a macronutrient for both plants and animals.’
      • ‘Potassium, a macronutrient for plants, is present in plant dry matter next to carbon, hydrogen, oxygen, and nitrogen and before sulphur and phosphorus.’
      • ‘Other macronutrients include potassium which helps maintain water balance and is involved in protein synthesis.’
      • ‘It indicates that there are measurable reductions in use of chemical fertilizers - most farmers use a combination of compost, animal manure or crop rotation to maintain fertility and replace macronutrients.’
      • ‘The main characteristics of such soils are infertility due to the low level of macronutrients, a Ca: Mg ratio < 1, and the high concentration of heavy metals; moreover, these soils are shallow, well drained and prone to erosion.’
      • ‘Lodhiyal et al. pointed out that the major macronutrients limiting the production of a forest crop are N, P and K.’
