NPK Starter Fertilizer for Fast Early Growth

SpringuP is a liquid phosphorus fertilizer starter designed to give plants a jump-start on the growing season. The combination of phosphorus, nitrogen and potash sets the stage for strong, early growth. SpringuP can help plants emerge faster, giving them access to warmth and sunlight sooner.

Benefits of NPK Starter Fertilizer

When crops start the season with the nutrients they need, they can emerge faster and start growing sooner. However, most seedlings struggle early in the season to draw nutrients from soil that is still cold. SpringuP gives crops a boost by supplying phosphorus, potassium and nitrogen right from the start. This is especially important for seedlings, which do not yet have robust root structures to access nutrients within the soil. Since phosphorus, in particular, is not mobile in the soil, it can be especially difficult for seedlings to access phosphorus. Applying an NPK starter fertilizer gives seedlings access to essential phosphorus at critical growth stages, and supports faster root growth, which in turn supports faster growth overall. SpringuP fertilizer is formulated to maximize plant-available nutrients, so they remain available throughout the growing season, instead of becoming tied up in the soil.

Choosing the right NPK starter fertilizer is important. Seedlings are very delicate, and some fertilizer can damage their new growth. The SpringuP liquid phosphorus fertilizer starter is gentle enough to use at planting, with very little risk of tissue damage to young plants. Many different types of crops fortified with springuP at planting have shown to emerge faster, greener, and stronger. This can help farmers get an early start in the growing season and bring crops to maturity sooner.

Product Benefits

  • Stimulates early growth
  • Can be applied in-furrow or with planter placement
  • Low risk of seed or seedling injury
  • Can be applied with other nutrients or crop protection products

Applying SpringuP NPK Starter Fertilizer

SpringuP is easy to apply and works quickly after it’s applied. This fast-release formulation helps to promote fast results and get plants started as soon as possible. With the ability to apply springuP in-furrow, banded over the seed zone, or through fertigation, it’s easy to find the right way to get necessary nutritions right to the seeds. SpringuP can also be applied with other nutrients or crop protection products, so you don’t need to make extra trips to apply it.

How to Use an NPK Starter Fertilizer

An NPK starter fertilizer can be beneficial for many different types of crops in many different areas. Some crops and some soil types will benefit the most. Corn is particularly responsive to an NPK starter fertilizer. Farmers using conservation tillage systems will also see more benefits from a starter fertilizer. Also, soils with low nutrient levels will benefit most from a starter fertilizer. To see the nutrient quality of your soil, we can help you perform a soil test.

Starter fertilizers are most useful during the spring, when the soil is cold and wet. Optimal application methods for the fertilizer depend on the type of crop and planting method you are working with. For corn or sorghum, for example, it’s best to place the starter fertilizer about 2 inches beside and below the seeds. It can also be applied directly to corn as a pop-up, or banded with forage crops. Our agronomists can help you find the ideal application method and fertilizer plan for your crops, soil type, and planting strategy.

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.

Tested and Proven

Laboratory conditions can show us what cutting-edge agricultural technology does, but not always how it works in a real crop setting. Our North Central Research Station allows us to test our fertilizers in real farm conditions. With over 1,000 tillable acres and a wide range of row and permanent crops, we put our fertilizers to the test. Our products are carefully tested and the results measured over multiple seasons. This allows us to see the effects of each fertilizer in real time, including how the solution promotes growth, any leaf damage, how it interacts with rainfall or drought, and much more.
