Influence of Soil Temperature on Corn Germination and Growth. We experienced June-like temperatures in March. Trees budded, spring flowers bloomed and fertilizer rigs crisscrossed fields. Soil temperatures matched what we normally experience in late April and early May, jumping well ahead of previous records.
An algal bloom is a rapid increase or accumulation in the population of algae (typically microscopic) in a water system.
An important factor in the growth of algal blooms is an influx of nutrients, particularly phosphorus, resulting primarily from spring runoffs and erosion from farmlands and urban yards, which are often polluted with excess fertilizers. The bloom will disappear if the input of fresh phosphorus ceases.
