Table 1. Some Common Mineral Functions and Deficiency Symptoms
1)
2)
3)
Mineral supply and growth
4) 0% water only, 1%, 3%, 5%-inorganic fertilizer best nutrient supply and growth
At 10% the inorganic fertilizer improves growth and in the case of crops the yield would also be better
6) When there is less than optimal nutrient supply there is stunted growth, inadequate supply of nutrients this is also associated with decreased plant productivity and fertility. When plants are nitrogen deficient the leaves die from the tip and turn brown.
7) Oversupply of nutrients also harms the plants and affects growth negatively. For instance, nitrogen is crucial to producing chlorophyll and absorbing light, but too much nitrogen in fertilizers can result in nitrate toxicity when the leaves and steams ‘burn’ and can also promote fungal diseases.
