Prevent and Correct Magnesium Deficiency in Crops

Like all secondary nutrients, plants do not need large amounts of magnesium to thrive, but an absence of the nutrient will cause stunted growth. Our liquid magnesium sulfate fertilizer makes it easy to correct magnesium deficiencies at planting, or at any time during the growing season.

Magnesium is a key component of chlorophyll. Without magnesium, the plant cannot produce chlorophyll, which will cause photosynthesis to suffer. Magnesium also plays a role in the transfer and production of sugars, starches, fats, and oils within the plant. This means a lack of magnesium will cause starchy vegetables, sugary fruits, and oil seeds or nuts to lose their shape and flavor.

Fortunately, magnesium is mobile in plants, which means correcting the deficiency as soon as possible will allow the plant to continue growing normally. However, it is ideal to test the soil before planting and test tissue from the previous harvest to determine magnesium content and uptake. If you discover a magnesium deficiency, our magnesium sulfate fertilizer can be easily applied with other nutrients to correct it quickly.

Have us design a custom nutrition plan for you

An AgroLiquid nutrition plan is dependent on your location, climate, soil conditions, and goals with your crop. All of our tailored programs start with reviewing your soil samples with one of our expert agronomists. After our analysis, our team will provide you with a couple options that will help you meet your goals on a budget that won’t break the bank.

AgroLiquid Scientific Advancements

It is difficult to tell on the surface what plants are deficient in, as many nutrient deficiencies show similar symptoms. This is why we perform soil and tissues tests. These tests determine nutrient content in the soil, as well as how much of those nutrients are actually available for the plants to use. With this, and a variety of other research methods, our experienced agronomists are able to detect and solve nutrient deficiencies in all types of crops, soils, and climates.

Nutriq Technology

This bonds with your nutrients and creates a protective layer that makes up to 80% more of your nutrients available to plants. It sounds like magic, but it’s just science.
