For 20 years, BioGro products have been placed in-furrow. This is the most important application window for bio-products that aid in root growth, regulate set and also may help with plant stresses.
Spray in-furrow, directly on the seed piece. The good microbes (happy faces) are the first ones the growing roots encounter, helping keep the bad ones (mad faces) from colonizing the roots later.
In-Furrow applications are important for concentration; spraying our program in-furrow is equal to an early water run of 18 gallons per acre! Get the most out of your starter and bio-fertilizer package and put it where the plant really needs it for early root growth and development.
At this stage, products that stimulate fine root-hair development and VAM (vesicular-arbuscular mycorrhizae) growth begin to show positive results by increasing uptake of immobile phosphorus (P).
More root-to-soil surface contact means more P for the plant. You can rarely increase P levels in the plant. The level you start at is the level you get all year, which is why it is so important to start right!
VAM increases the soil-to-root surface area for a fraction of the energy required to build a root hair. VAM helps plants grow better in moisture and heat stress. It is a must in potato production.
Phosphate is immobile and is needed early in the plants growth cycle, so the goal is to apply products that maximize the root to soil surface area by:
From 6” rosette to full row closure, the potato plant develops most of its canopy dry matter, and it takes up 60-80% of its nutrients, especially potassium (K), at very high rates. For a 30 ton/acre yield, the plant may require up to 20 units of K per day, far more then even some of the most fertile soils can provide.
Applying 5-10 gallons per acre of CHB Premium 6 during this rapid growth cycle provides enough humic acid colloids to increase the uptake rate of nutrients, especially potassium. Yield potential is not only limited by the amount of K present, but the ability to take up a volume of K.
You now have the ultimate factory for producing high yields and quality:
All the energy to grow roots, to grow healthy vines and to maximize the amount of starch (solids) available to the tuber, comes from photosynthesis.
Especially when it is known that there are many good microbes (PGPR and VAM) that help promote plant growth and nutrient uptake! BioGro’s program promotes a sensible approach, although we don’t recommend eliminating fungicides; we do promote a system of starting plants with good root microbiology early in the growth cycle, when the plant’s root system is small enough to manage. Early application and volume of bio-product is the key to success!
