In-season Foliar Potato Fertility | Farm Progress

Background

Assembly the nutrient demand of the potato plant is a important element of reaching yield objectives in potato manufacturing. In mild of this, important consideration is concentrated on fertilizer fee and timing in potatoes, using soil checks and petiole tissue checks as the primary instruments to make sure sufficiency all through the manufacturing cycle. There are completely different timings and strategies of utility, akin to: pre-plant, soil-applied, at plant, 2 x 2 or in-furrow, in-season fertigation and in-season foliar sprays.

Every timing/technique is necessary and can be utilized to nice impact relying on the nutrient and the objectives of the guide or grower. When the objective is to keep up optimum potato progress and/or forestall or appropriate nutrient deficiencies, in-season foliar sprays could be an efficient instrument.

Situations That Result in Nutrient Deficiencies In-Season

There are a number of causes nutrient deficiencies can happen in potatoes. One cause is that plant nutrient demand can outstrip the power of the soil to produce that nutrient. Potassium (Okay) demand from tuber initiation by way of early maturation is extraordinarily excessive. This places a whole lot of strain on the soil’s fertility to produce Okay throughout that point. As well as, leaching of key vitamins can contribute to nutrient deficiencies in-season, particularly on sandy soils when that nutrient just isn’t spoon-fed through fertigation purposes. This could happen with all of the vitamins which might be cell within the soil, together with nitrogen (N), potassium, calcium (Ca), sulfur (S), boron (B), and manganese (Mn), and is often extra of a problem in the direction of the second half of the manufacturing cycle.

Potassium Deficiency in Potato

Another excuse nutrient deficiency can happen can be excessive pH’s on calcareous soils (pH > 7.0), the place micronutrients akin to B, Mn and zinc (Zn) develop into a lot much less obtainable to the plant. Antagonism between vitamins for plant uptake, significantly when one nutrient is current at excessive ranges, could be a problem that causes deficiency as properly.

Methods to Preserve Optimum Potato Progress and Stop Nutrient Deficiencies

There are a lot of alternative ways to forestall nutrient deficiencies and promote optimum potato progress. Foliar sprays are a very good answer when: speedy, reliable uptake is necessary, you are not attempting to produce a considerable amount of a nutrient, and/or the pH or antagonism with different vitamins within the soil will forestall considerable uptake, which might preclude a soil utility. An necessary technique for monitoring nutrient deficiencies which might be or could also be growing in potato is petiole testing.

Key Utility Timings and Charges

The BRANDT® Sensible System® product line, together with BRANDT Sensible Okay B and BRANDT Sensible Trio®, make use of a sugar alcohol supply system that enhances the entry of vitamins into the potato leaves and the mobility of the vitamins after they enter the plant. They’ve a low salt index and are appropriate with many pesticides, typically permitting you to tank combine both of them with a pesticide spray already deliberate (jar check to confirm).

Suggestions: In-season, typically with a pesticide utility (to reduce journeys over the sphere)

  • 1-2 qt/ac of BRANDT Sensible Okay B at any level from tuber initiation to early tuber maturation with appropriate pesticides.
  • 1-2 qt/ac of BRANDT Sensible Trio at tuber initiation to dime measurement tubers with appropriate pesticides.

BRANDT merchandise can be found at ag retailers and sellers by way of the U.S., America’s, Europe, Africa and Asia.
