The buffer pH in an indication of the soil’s ability to resist a pH change. The higher (more basic/alkaline) the buffer pH reading, the smaller amount of lime is required to raise an acidic soil pH...

Cation exchange capacity (CEC) is an indication of the soil’s ability to hold or absorb the cations or fertilizer that is applied. The higher the CEC, the more nutrients the soil will hold. You can...

In plants, Zinc (Zn) is essential for transformation of carbohydrates and regulates consumption of sugars.

Micronutrients are essential nutrients for plant growth that are only needed in very small (micro) quantities. The seven elements listed below are generally recognized as micronutrients, although o...

Magnesium (Mg): Activates many plant enzymes needed for growth, central atom of the chlorophyll molecule which makes it absolutely necessary to photosynthesis

Calcium (Ca) is an essential part of plant cell wall structure that gives the plant its strenght and plays a key role in root system and leaf development. While plants require calcium, this element...
