Potassium & fertility: Higher alfalfa yields

February 8, 2016

Many elements are essential nutrients for plants. In relatively large amounts, the soil supplies macronutrients: nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. According to Purdue University, to keeps plants healthy and give them the best chance to compete against insects, diseases and other stresses, a balance of these nutrients is essential. The proper amount of potassium is critical for growth and development, particularly for alfalfa. Potassium helps alfalfa crops become higher-yielding and higher-quality, all helping maximize performance and profitability. Potassium also:

  • Helps regulates enzymatic processes in the plant
  • Enhances root development and tolerance to temperature extremes
  • Improves drought tolerance
  • Minimizes susceptibility to disease

When thinking about applying potassium to alfalfa crops, its best to take a balanced approach. It’s extremely important to consider the plant’s needs before fertilizing. Therefore, be sure to test the soil for potassium levels and fertilize accordingly. Adequate nutrition maintains alfalfa’s vigor and ability to deal with stresses. Proper levels of nitrogen, phosphorus, sulfur and potassium helps ensure high yields of quality forage, ultimately helping you grow more alfalfa.
