Water-Soluble Soil Tests for Crops

Plant tissue testing, as done by most labs, is not as informative as water-soluble soil tests. Tissue tests only test the soluble contents of the cells.

Foliar Feeding for Soybeans

Foliar feeding is a complex subject, but in general it allows you to supply small amounts of deficient elements to plants (through their leaves, primarily) at the time they need them. Fertilizers applied to the soil before planting may not be available to the plants when they need them most—during peak growth and pod fill. […]

Examining foliar health could give you the clues you need to find which nutrients and minerals are deficient, or in too much abundance.

Signs of Nutrient Deficiencies in Soybeans

If a plant is not getting the proper amounts of nutrient elements, it may develop certain symptoms, abnormal colors or growth defor­mities.
